very nice!

btw, i know its cool to dress up the engine, but the blue just dont look good at all. if i were you id go for painting things black or silver.

[Drocay]

looks great man, but i agree with lagos it looks wierd but if u get it to run then i don't care wut color the bay is

[97sccelica]

dont waste anymore time painting stuff

get that hybrid running!!!!!!!

and since your going with a custom wire harness, why not get somethign better than an ae86 ECU?

[Kwanza26]

Cool... I'm gonna be doing that sometime soon... ;]

My question, why'd you use a bigport head? With that, what intake manifold are you planning to use? And why the Ae86 ECU/ Many questions... hehe. Looks good so far. And you might have to get a new dizzy... unless you're gonna splice.

[celicarocker]

it looks fake blue... like it doesnt look like a real engine...

[Dr_Tweak]

Looks awesome. Forget what everybody says about the color, if you like then go for it. I think it looks good.

What kind of boost are you planning? You are using 4AGZE pistons, right? That's exactly what I'm planning right now...

I'm gonna use Megasquirt though.

[frotou]

This is not the real color of the blue ; it's because of the flash...I run the ecu to go with the distributor and with e manage .... I'm sure it will be suficient for my setup.I plan to boost 8 lbs in break-in (5000 km) and after I don't know ...My friend plan to boost at 18 lbs with a 7agze and stock rod .

Celica rocker : come see later I will send pics of engine in the car ....

I use the big port intake with the tvis removed ; maybe a four throttle upgrade later ....

[FallenHero]

18lbs... that doesn't leave a lot of room for error. You are looking at lots and lots of tuning my friend. I can't wait to see how it turns out.

Awesome stuff man, Have any pics of the whole car?? Dont worry about these guys they are just jelious haha jk

The most Ive seen done with an ST on this site anyways!

Im with the guys that say to forget the other guys.... ?... lol anyways I think that the color is perfect for the yellow engine bay and car. It should look really nice when all put together and make sure to post specs and pics when done. Way to go man!

[dstrbcelica]

looks great man! can't wait to see some pics when you get finished and have everything up and running!!

[x_itchy_b_x]

its gunna haul "butt" i bet

[Digndoug]

Man that is awsome, thats crazy, first, why did you choose building up an boosting, second how muh is this stuff costing you. an how much power are you planning?

[frotou]

My goal for this summer is first to make the car run ... After the break-in , I plan some hours of tuning on a dyno and run 14-15 lbs of boost. I expect 220-230 hp at the wheels. Yes I have also a wiring from a ae86 to splice with my harness; after some hours spend on my wirings diagrams I plan 1 day or two on it . I don't calculate the cost for now , I wait to have finished . The main reason to have go with this setup is because I will be the first to have it in a celica . (I think ...)The motor is in the car and the manifold is completed ; I'll send pics this week .

Thanks for the encouragement !

(The guy who plan to boost at 18 lbs will make it in a ae86 and with a supercharge , so I think it's different than 18 lbs from a turbo)

[van95st]

looks beautiful, you didn't say anything about a tranny though, are you sticking with stock?

[SpedToe169]

Looks good. We'll all be very interested in the info on your G head swap when you get a chance to go in depth about it.

[toyotaspeed_90]

i've said it before and i'll say it again (maybe on this forum, maybe not).... if you're going to use an ECU with t-vis (like ALL 86 ecu's) then DON'T REMOVE THE T-VIS...... it'll freak the ecu out when you get to those rpm's and it isn't there..... from all stories of those removing the t-vis and not doing anything with the ecu, when it gets to the (~3800?) right rpm's, the engine actually hesitates & slows down.... then it jumps back up accelerating.....

but yeah, it won't be happy that it's not there.... if possible, use a 90-91 ecu..

btw, you shouldn't need a custom harness...... find an ae92 (redtop bigport with t-vis)... the harnesses should plug into the ae86 ecu (same bluetop ecu... just the blocks are different)... but i'm not 100% sure on that one.... but in any case, i'm using my 4a-fe ecu and wiring on a 4a-ge..... just need to lengthen a couple wires

and i would suggest since you're spending all the money as it is and spending the time for the rebuild.... go with something other than a US 4a-ge ecu.... go with something that is map based... just IMO

[kuruptedsnake]

will those cam gears work on my 7afe

[toyotaspeed_90]

[kuruptedsnake]

ok then where can i find cam gears or cam sprockets

[FallenHero]

the 7a is a slave cam engine. they do make cam gears (look up 93 Rolla on nopi) but there's really no need if you aren't boosting.

[kuruptedsnake]

really why not?

[97sccelica]

[frotou]

Finaly after hard times the manifold is completed and the motor is in !









I repeat it ; the blue look very bad because of the flash ... Now waiting for the intake and valve cover (chrome) and I'm now in the intercooler piping . There is not a lot of space for it . My car have been in accident last summer and I will send pics of it later. Now my biggest concern is for the management ; some friend are tell me to go with jdm 4agze map ecu , I have the ecu , the igniter , the crank angle sensor, the map , the coil pack, the 365 cc injectors but no wiring .... Maybe I'll start with the standard ae86 ecu and upgrade later .

how is your project coming along? I'm in limbo on which type of build up I want to do. The 3sgte or 7agte. I'm really starting to like this build up. I saw an engine on club4age It was awesome ! good luck with the project please post some more pics!

edit: lol he posted these pics as I was writing this.

Go with 3sgte if you don't like to fit things (custom work) .... My motor will cost more and take more time than swapping a complete 3sgte kit . I choose it to be different and as a personal challenge .

[Punch]

you should use 4A-GZE wire harnese it comes with a MAP sensor.
It's does not ues a air flow meter, thats the best for turbo toyota, all the big toyota pros go that way!

[Jeremy1210]

any updates on your engine?

[frotou]

See topic ; celica 7agte started last week .

[FallenHero]

I have heard you have to re-locate the Alternator for a 4ag. Is that true?

[Kwanza26]

[FallenHero]

yea, just throwing this out there, those cam gears from HKS he has cost a bleading fortune.

Hey Kwanza. I am Probably going to end up doing this in one form or fashion and using it as my DD when i get out of school. I'm probably going to use 256 duration cams so my car will still idle properly. Do you think I should go with more if I do ITB's? And I am going to use the big port head.

Also, HKS' cams are most likely the best, and highest quality, but web cams make some that are $330 for BOTH, not $270 someting each. What are your thoughts?

[frotou]

I have now a wiring, ecu, igniter, coil pack, crank angle sensor from an ae92 jdm 4agze map dli; this is my next challenge/update for this winter. No more "us" ecu and *&?%$/! afm ! I read and look for the autronic stand alone management ; it's very complete and high quality but not really worth the cost for an 220-260 hp engine ... We will see !

[FallenHero]

I'll be flat out honest with you. I'm going to call jet and tell them what I am going to run, and see if they can get a roundabout ecu set up for me. that way, I don't have to change any wiring, and it'll be plug and play. (plus I can fine tune with the AFC in that manner) And I also was under the impression that if I used the ITB's, the port size really wouldn't be that major of a problem. After all, the intake will be controlled by the ITB's. I wouldn't think the flow characteristics would really hurt power. I figured there would be a torque loss, but not that major of one.

IF the 272 cams are running well for you, I might just go that route. What did they run you? Also, what are you thinking for a redline. I was thinking 6500-6800. Probably 6500 because the block will have 120k miles on it. that coupled with a .7 or .5mm metal head gasket could lead to compression worries.

I figure all that would Easily topple the 130 hp mark. Throw on a few basics (header, exhast work, UDP) and it could make considerably more power. In the end. I'd like to see how it would run agains a stock 7afe turbocharged. Were i to rebuild the block properly, I think the all motor 7a with a bit more compression and the above head work would easily take a 7afte. But price wise... I will probably end up spending more money.

However, when I set out on this I said it would be a reliable DD, not a weekend race car. I just want a little more under my right foot. Plus, it's going to be a fun little project.

[Kwanza26]

[FallenHero]

Use AEM cam gears. You'll pay for them, but you can get a variety of colors. That's fairly cheap for cams, and probably the way I will go. And yea, I have heard about the 2zz rods, pistons, and even crank being very close to a 7a fit. A bit out of my price range for now though.

I see what you mean about Velocity. It never crossed my mind That explains the tivis 'increasing velocity'... I have large port parts available to me. I don't know where I would look to find a small port head and intake. they cane in the late rollas before they started using the 7a right?

[Gilbert_619]

wow thats a damm hott ride for sure...that manifold looks crazy...
the paint is all crazy too

you should get a custom guage set from doggy...a nice yellow one

[nik]

well i know who to talk to when i take the plung into the 7agte world. But for now i'm exploring the limits of the 7afte

[Kwanza26]

[frotou]

My engine finished (expect the management) I love the sound ;



Now I can't wait for the spring ...winter will be long for me

Claude

[dstrbcelica]

wow. you are the f*ckin man. looks great!! u should post some sound clips or something. wow...

-dstrb

[FallenHero]

[Kwanza26]

[FallenHero]

check a price for the smallport head for me with the manifold and crank gear.

[Kwanza26]

[Dr_Tweak]

I would seriously recommend getting a Megasqurt setup. You are going to need programmable engine management anyway because of the turbo, and since you don't have a wiring harness this is a perfect opportunity.

If contact the guy a www.4AGTE.com or .net he can help you out, and I know some other people as well. Too bad you don't live close otherwise I could hook you up.

[KAMiX]

Dude that is ****ing awesome... mad props.
