7a rebuild and Vortech Supercharger Options

[al94st]

So first off, I've been using this forum a lot for reference and information in the past few months and it's a great tool for anyone who owns a Celica, so thanks to everyone who puts up good information.
I'm in the process of rebuilding my 7afe. It had 136000 on it when i pulled it out, but it hardly looked like 30000 were on it once i opened it up except for some oil sludge. I purchased a V-5 vortech f-trim to put on after i get the car running again, but I figured I'd share a few pics of the rebuild and update some more when I get to the fun stuff.
Pulled the engine in Feb, (i travel around the world a lot, so I've been off and on with this project) brought block and head to my machinist. Block only needed a fine hone. Head didn't need much, but had a valve job done just to freshen it up since 16 yrs on the valve springs is probably enough. Started rebuilding on Wednesday and relaxed today, I might finish rebuilding tomorrow.


Block painted and piston one reinstalled.




nice picture of the little 7a rods


head and cams installed, water pump on


timing belt installed

wow. very unique. Have never heard of anyone putting a supercharger on a 7a. keep the info comming

[95celicastLSR]

i have thought about this because of instant boost and great low rpm tq. this may turn out to be a start of a whole new way to power the 7a"S..... great work man keep us up to date

[Johnnyny]

if you want some low rpm power get some cams work done

[al94st]

As far as I've seen the stock cams are designed for low rpm power and efficiency, that's part of why the 7a gets sluggish in the high RPMs. Grinding the cams is going to give you better power in the upper RPM range. I don't think it'll do too much for low RPM hp and torque.

[SwissFerdi]

I'm very interested to see how this'll turn out, I was under the impression that a supercharger on a 7A was impossible due to the positioning of the intake manifold.

[Nartanian]

This should prove to be interesting.

[JoKeRkId613]

the v5 might be a little big for the 7a, but props on building the brackets to make it all fit. it's a good blower.

[al94st]

Quick update. Yesterday I started and timed the engine without any problems. I'll try to get a couple pictures of the car up in the next few days. Once I get the car back on the road I'll break in the engine then start installing the blower.

[Tom_SS2]

i heard a 7A-GZE had been done before using pars from the 7A-FE and the 4A-GZE, but i suppose you're trying for a 7A-FZE?

edit;

quick google finds a you tube vid of a 7A-FZE

[JuMPiiN]

Nice vid find, GL with your build bro, this is def different.

[cheela]

very interesting indeed. I'll be peeking into this thread to see how it goes. Good Luck with everything. hope it turns out well.

[al94st]

I've put about 90 miles on it since rebuild. I also installed my megan coilovers. Very happy with them. I had a header on the car when I put the engine back in, but I decided to take it off until I have more time to mess with the exhaust. I plan to go 2.5". Current setup is stock with supertrapp muffler. I'll probably start messing with the blower in a month or so.

Quick update on this. Haven't given up on the project, just on hold for awhile because I'm in the process of relocating to NC. Just installed a new exhaust system.

In order to make the Vortech fit nicely, I need to make a solid motor mount for the passenger side that attaches further back on the frame to open up some room and help with the supercharger mounting. Then the relay box and windshield washer filler tube need to be moved (which is simple). It might just fit under the hood after that.

[celica74]

What part of NC? im located just outside of raleigh

[al94st]

Wilmington

[HectortheRican]

Nice choice of wheels! I dunno how to explain it, but they flow nicely with the body lines. I can't wait to see a supercharged 7A, that'll be cool.

[celica74]

might have to take the 2 1/2 hour drive to check it out when your all done

[al94st]

Thanks, they're 15x7 Drag Dr-17's. They're like 14 lbs I think. Discounttire.com sells them for 100 a piece including the hubcentric rings and lug nuts.

Might take a little bit , but that'd be cool.

Haha thanks, I'll keep that in mind when looking for replacements. Right now I have 17x7.5 Drag DR-19's.

[GriffGirl]

2.5" exhaust is going to be a tad big for a 7A, even when it's supercharged (or turboed too for that matter); you'll lose some low-end torque due to lack of back pressure. You might want to reconsider and go with 2.25" exhaust.

PS: I <3 this thread already and will be very interested to see how it progresses!

[al94st]

I actually just redid the exhaust to make the car my daily driver again, now that I'm not traveling all over the world for work. I put in a silver powder coated ebay header and down pipe (which is burning off the powder coating nicely, but at 45 bucks who can complain) cut out the cat and ran a Walker resonator pipe and Walker stainless quiet flow muffler. It's all 2" for now.

Also disconnected the second O2 sensor and haven't had a light or any issues. (yay for pre 96)

Finally getting back to this project, bought supra 315s and 2 bar map off of Manny. Haven't decided if I want to buy engine management or wait to see how it goes without it. Has anyone run 315 injectors, 2bar with no tuning on the 7a?
Went to dyno day at a speed shop down the road today, seeing the power some cars are putting down these days makes me wonder why I'm doing this in the first place haha.

I often wonder the same thing...Just remember your Celica will be/is one of kind.

[al94st]

Having trouble locating a good oil feed adapter block to purchase, any ideas?

[al94st]

Oil pan painted and oil return installed...10an


Oil pan reinstalled

[al94st]

Well, my walbro fuel pump, stoich gauge, breather tank, NGK plugs, and new welder got delivered yesterday, so I suppose I have some work to do this weekend. Once my pulley from Vortech comes in on Monday, I'll be able to start making up some brackets for the damn thing.

[al94st]

Finally got my gauge holder finished and gauges all set up. I wanted something different than pillar pods, so I did this:

[al94st]

just so you guys get an idea of where this bad boy is going. I'm moving the alternator to the rear of the engine, the blower will be run off the inner (4rib) belt, the same one that spins the A/C compressor.

[SwissFerdi]

Wow. Best of luck. The awesomeness is strong in this thread!

[al94st]

hard at work..should have it mounted soon...

[al94st]

Mounts made up (unfortunately the process took forever long), I'll take better pics of how I did it later. Belt obv doesnt go like that, I was just using the old one to get the alignment right.

[delusionz]

edit;

http://www.youtube.com/watch?v=8AafhU0qiXE...feature=related

It sounds awesome, but it looks really slow compared even with a 3S-GE.

If it's like that with a supercharger, I hate to imagine what it's like 7A-FE in naturally aspirated mode

[al94st]

Yea the 7a is pretty slow. The blower on that car looks like it could be a sc12 or 14, which would be fairly inefficient compared to the vortech ... I really don't know what to expect. I'm sure it wont be a rocket, but it should make some decent torque.

[OOBE]

Keep on, bro. Our cars are unique. It's not about power. It's about being different. The 7A is a very fun engine when boosted. It might not offer cheap thrills like stronger engines but it's VERY enjoyable.

[al94st]

I got an idler pulley and found the right belt length, so the supercharger side of the project is pretty much done. The alternator on the other hand has been a bit of a challenge. I made a bracket and had it mounted to the rear of the engine, then realized it's almost impossible to tension the belt enough with it back there to make sure the water pump will be spinning and I'm not about to risk problems with that. It looks like the best case scenario is mounting the alternator back on the front side, but turned around backwards. I also was super happy when the s****y brass Vortech oil feed snapped on me when I tightened it, so now I need a stainless one for another $55. BS if you ask me. Even better, I had to pull the damn supercharger apart to get the broken one out.

I had to put the car back together so my wife could take the Genesis to FL and I wanted to make last weekends meet in Raleigh, so here's a little pic of my temporary DD setup. Once we're back from vacation, end of the month, I'll work on finishing this.



Things left to do:
Mount breather can to firewall
Alternator mounting and belt
Install walbro
Cut, weld, install intake piping
Make heat shield for Hot as **** Ebay header

Burn rubber

[lagos]

Really cool project you got going here!

[al94st]

Thanks Lagos

[PolliS_5S-FE]

do the ebay headers get hotter than stock?

[al94st]

It seems to be pretty hot and at least the stock manifold had a heat shield too. I definitely need to do something since the intake for the supercharger is right next to it.

[Smaay]

that AF gauge is junk, its not accurate, you need a wideband O2

[al94st]

It's really not junk, I wish people would stop making that statement or "it's just a light show" lol. It does exactly what it's designed to do. It's just not sufficient for tuning your car with, which I'm not doing since I have a dyno right down the road to check the a/f ratios once I get the setup completed. If you undersand exactly how it works, it's useful. A lot of gauges could be considered useless, but if you know the car's trends, little changes can be big indicators before things go wrong.

true statement!!!^^^^^ looks good my friend. although its not super fast all that really matters is a unique mod done to a unique car. cool thing about different people is they have different likes and dislikes. and not to mention diff taste in car and diff. ideas. keep up the great work.

[al94st]

Thanks, dedicating this weekend to trying to finish it. Pulled out my A/C and I'm making a new bracket to mount the supercharger. I wasn't happy with trying to relocate the alternator. I'll try to take a bunch of pics as I go at it.

[al94st]

So like I said I decided to make a new bracket and ditch my A/C. I spent the whole weekend fabricating crap, but it's almost done. I'm waiting on the silicon couplers for my intake piping and then I'll be able to hook it all up.

First I started with some 3/16 steel. 3/16 only because that's the limit for my fluxcore welder (also why all my welds are ground down)
So I cut up some pieces like so.


Before that (last weekend) I welded up some steel on the A/C bracket so eventaully the supercharger bracket could be welded to that. Yea I could've made it so it bolted to the A/C bracket...but that would've been a real pain.


So after some welding, grinding and more grinding I had something like


Then I welded that up to the A/C bracket after a lot of measuring and in and out of the car crap


Then I messed around added another piece to the bracket for more stability since it's only 3/16" I figured better safe than sorry. The picture is crappy and doesnt really do justice of the time it took, but w/e.


Then after that I started make up piping. 2.5" Hooker J pipes...cut..weld...grind..cut..weld..grind..grind..grind. I also welded up my BOV flange, but I didnt take pics. It's not alumium its mild steel, but looks shiny from hitting it with a 120grit pad on my grinder.



I installed the Wlabro pump like a month ago...and I think I have the right length belt now after realizing the one I got yesterday was too long. So once I get the couplers I just have to put everything in, connect the oil lines, which are ready to go, and reinstall the 2bar map and injectors.

[al94st]

Vortech charged 7afe alive and crusining. It's running suprising well for noy having any tuning. I expected it to idle like ****, but it's fine. I don't know where I'm going to be with boost yet as I've taken it pretty easy today. How do most people insert their IAT's into their piping? I drilled a hole and insert the gromet then the IAT and RTV'd the whole thing...but is there another option? Sucks that it's made of plastic. I'll try to get a vid up today :-)

Weld in bung in the piping. Atleast thats what I did.

[SwissFerdi]

Congratulations, I'm anxious for the video, and for power numbers.

[al94st]

Just need to get my header wrap on there.


Thanks, I took a vid but I can't find my cord for my video camera so at the moment I can't upload it. I have a meeting with the dyno on Wednesday. Looks like I'm around 5-7 lbs of boost right now..and I don't know if there are any leaks or if my gauge is accurate, so I'm pumped to see what it puts down, what the a/f read out is, and what my boost is at.

This post has been edited by al94st: Jul 18, 2011 - 9:21 PM

[al94st]

OK got this thing on the dyno today. Numbers aren't incredible or anything (not that I expected they would be) but considering my boost is so low I'm pretty happy. I have a lot of room to grow with smaller supercharger pulleys. Also, remember I'm running 315cc injectors, 2bar map, walbro, and absolutely no tuning or intercooler.

[presure2]

Thats about what id expect without an intercooler or tuning.
can you clock the outlet so it points down and run the ic pipe down low to get away from the header?
I think water/meth injection would work wonders for ya, especially since your running no ic, and how close that pipe is to the header.
keep learning and progressing, next thing I would invest in would be a basic water/meth injection kit, and a used safcII, then get on a dyno again, and do some tuning.
i wouldn't be surprised to see ya gain 20whp or more with those 2 mods, or an ic and safcII

:edit:
Looking at the chart again, your,not really making any significant boost till almost 4rpm, which is way after the tq peak for the 7afe (iirc its something like 2800rpm)
would a smaller pully make boost sooner, or would you need a smaller charger, similar to turbo exhaust housing sizing?

I can clock it but I'm not sure about how far. I'll look into that. I do have header wrap on it at the moment tho, but yea it's realy close. I'll probably be looking into an intercooler. A smaller pulley should bring it in sooner I think. It's proportional to RPM, so I can't see why it wouldn't come in sooner since it will be spinning faster at a lower engine RPM. I do think it's a little large though, considering that's almost 50 flywheel hp on ~5lbs, so I think getting it spinning quicker will help. It's also hard to see on that graph but I must've had some belt slip b/c boost is bouncing in the low r's as well. On most of the runs boost was right between 4.5-5. Thanks for the input Manny.

[al94st]

I switched to a 2.62" pulley today from a 3.25" and it definitely made a difference. I can't tell what the boost tops at yet, it's really hard to tell b/c it goes up so fast between 4k and 6k RPM. Next I just need to decide on something to tune with and get an intercooler.

What's the main difference between the apexi SAFC and SAFC2...and is it worth it or should I get something like the Split Second PSC1?

[PolliS_5S-FE]

so its basically like a stock 5s, apart from torque, thats ok though. What costs have you run so far?

[al94st]

so its basically like a stock 5s, apart from torque, thats ok though. What costs have you run so far?

It's not really like a stock 5s, that whp not flywheel, if anything at that boost it was about on track with a 20v. I think Coomer's car dyno'd a 130whp. Anyway, cost a few grand. I stopped keeping track and I did a lot of other things at the same time, like interior, coilovers etc...so I'm not sure the exact cost. I spent $700 on the Vortech new from ebay. No I didn't spend $2300 on it lol. The whole reason I did it is because I got lucky and got a deal on it. BTW that dyno run is just a starting point, I'd ike to get about 200-210hp (flyhweel) out of it.

[Keiri]

Just re-read the entire thread AJ and you have done some great work. Glad to see you made it to the dyno and numbers are impressive compared to a stock 7A - good gains. Can't wait to see the car in person in August!

[Cuts_the_Pilot]

I like this, its different.
As you know getting that pipe a bit of distance from the headers would be good, then water injection or a fmic would help.
Would be a sh!t load different to drive, nice and torquey compared to stock.

[stephen_lee]

it actually looks like the stock tune is really nice, too. at about 12.5-13:1 the whole time. The 7a likes to run rich WOT so it worked out for u here

[al94st]

Thanks Brian, I appreciate it. I also looked back to the beginning and noticed my original plan was to make a solid motor mount attached further back on the frame to fit the charger...the reason I was thinking that is because when I bought the vortech on ebay it was labeled as ccw rotation. Luckily I noticed it was actually clockwise rotation before I made up the bracket to install it.

Ben is supposed to hook me up with a good deal on a FMIC when we meet up.

I made a little heat shield over the weekend that kind of wraps around the header (there's also header wrap on there). It's thin gauge aluminum, but better than nothing. Also got rid of the purple and coated everything with some zinc chromate primer and a little clear. Not everyone's cup of tea for color, but atleast I have corrosion protection to the max haha.

Nice!
Anything to keep the heat off that charge pipe is a good thing imo

[celica-s]

very nice install, i may ask, will a stock charger from a 4agze work on 7afe?

in the philippines its hard to find those vortech chargers, but i can definitely find/get a surplus 4agze charger.

TIA.

[PolliS_5S-FE]

oh sorry i thought that was flywheel hp, very nice then, you've done some decent power increase if you ask me. far from stock!

Yea you could use it, it's just a matter of making it fit, aligning it and all of that fun stuff. They're kind of dated though and it'd be hard to find one in really good condition without a lot of miles on it, but that would still be cool.

oh sorry i thought that was flywheel hp, very nice then, you've done some decent power increase if you ask me. far from stock!

No problem, thanks....it's an OK increase, but I can't wait to get an intercooler on it and get back on the dyno. It already feels a lot faster with a smaller pulley and more boost.

[celica-s]

a 205 bonnet and a top mount intercooler should be great!!! ????? hehehehe

[Cuts_the_Pilot]

a 4a blower would probably be a reasonable match for a 7a-fe, as they would have no where near the VE of a 4a-ge and dont rev as hard.

[Johnnyny]

this is great keep it up

[stephen_lee]

the 7a runs around 15:1 idle and cruise. more than 50% load it runs about 11:1

[al94st]

Got my front mount aftercooler, at some point I'll have to install it and dyno again.

[al94st]

FMIC and Half Radiator installed. For any 7afe guys thinking about an optional radiator, a civic half rad will work with the stock radiator hoses, you just need a couple pieces of metal to secure it. I'll try to get pics up 2morr. Turns out that vortechs are super easy to clock, you unscrew the 6 allen head bolts and can spin it any where you want 360degrees.

[cheela]

been waiting for someone to start a thread like this. It's totally different and looks like a fun ass ride.

[zoik]

i hope to see a sleeper version of a compressed 7afe

[playr158]

There is so much win in this thread!! Great work.
I was just in Wilmington two weeks ago, wished I would seen this!

Here's some pics, I still need to clean up/paint the piping and get some new t-bolt clamps, but it's pretty much done. I'm planning on auto x'ing the car on the 24th :-)

My 3 year old son "helping" me. Lol he's not a lot of help, but atleast he's interested.






Vortech


Civic Half Radiator, with stock 7afe rad hoses.

There are very simple aluminum L brackets (upper and lower) that I made to make sure the radiator doesn't move, but I missed them in the pics. I used the old top radiator bracket hole and one of the holes for the underbody plastics for the bottom (plastics are still installed).
*Edit - also forgot to mention there is a 1500cfm fan on the rad in the front, but it runs so cool it hardly ever comes on.

Thanks, I'm kind of surprised no one has tried the rad before (that I've seen anyway).

Yea, those ramps were totally worth the $ and time, I hate using the jack stands. They're way safer than those short plastic ones they sell too.

Well ran my first auto-x today. It was fun, but I tried to go too fast. It would've been better to try it out before I added the supercharger. It was still a ton of fun though and I can't wait to do it again. Here's a few pics, but the wife didn't get any action shots.

[al94st]

Well, I doubt I'm going to be selling this baby and since I can't leave well enough alone, there's probably a supercharged or twin charged 3s coming eventually. Need mo power.

[bsamps4]

Twin Charge FTMFW!

Why not try to twin-charge the 7A?

Glad to see you're not selling, I never understood why people invest into a project like this and then sell it shortly after completion.

You would have to fully build the 7afe and get a better head to be able to spool two chargers. Displacement is too small but it might work if you have a smaller charger spool a mid sized charger. Would be an interesting build. Good job Al! post results of the Autox event? 3sgze? Sounds fun haha!

Why not try to twin-charge the 7A?

B/C it wouldn't be worth it. Id have to buy the turbo and manifold, up the injectors, get some type of engine management, and tear the engine apart to put in stronger internals. If I get a 3s I can build it and still drive the car. Plus I just think the 7a is too smal...I want a lot more power.

Thanks, Auto-x results = crap haha. 3rd from last. Only a 240 that DNFd everytime and a mustang were behind me, but it was still fun.

Well, I doubt I'm going to be selling this baby and since I can't leave well enough alone, there's probably a supercharged or twin charged 3s coming eventually. Need mo power.

make rod millen proud!

Well it don't matter what you placed as long as you had fun! I wish I could AutoX my Car but it's down due to oil pump leading to bad cams... Any definite plans on engine? As to twin charged, ect?

Nah, no decisions made as of yet. Just preregistered for autox this weekend, but might go to the drag strip on Fri instead...still up in the air.
