6G Celicas Forums

hey guys, since i've been fielding alot of questions about turboing the 5s, and most of the links in the 5sfte sticky are dead, i figured i start a thread about the buildup of my kit, and try to include as many details as possible, so everyone can learn a little more about what exactly goes into a setup like this. ill keep updating the threads and adding pics and stuff as i upload more ect..
im not gonna get into the whole why not swap a 3s instead debate here, thats a dead issue as far as im concerned. (not that i think swapping is a bad idea, just not for me.)
so, ill start off by saying the single most important thing you can do if you wanna turbo your 5s is RESEARCH! take your time, learn about the diffrent systems that all work together to make a good kit work. go to www.howstuffworks.com and find out how EVERYTHING works, it'll make understanding the hows and whys of everything so much easier. i've been reserching about this for 2+yrs and i STILL learn new things everyday.
#2 is DONT BE CHEAP...can you do it cheap? yea..will it last? prolly not.
thats gotta be the SINGLE biggest mistake i see EVERYONE make. cheap out on all the little stuff, and it WILL come back to haunt you in the end
that said, i decided i wanted to turbo my 5s. lol
so, off on the hunt i went...parts lists, install sites, the burien kit...i searched it ALLLLLL...for MONTHS!! talking to people, looking at sites, printing info..basicly what the old timers call "goin to the woodshed"
then, i started looking for parts:
3s exhaust manifold, ct-26 turbo, oil hard lines, elbow and primary cat (also known as a downpipe), if your not planning on getting a aftermarket downpipe. also the oil pan and 2bar map sensor.
your gonna want these off of a 2nd gen 3sgte from a 90-93 alltrac or mr2T, and are pretty easy finds over on www.alltrac.net and or www.mr2oc.com. if your not a member of these 2 sites, YOU SHOULD BE!!! theres a wealth of info on these to sites, and while alot of it may not be 5sfte spacific, its still VERY good info, especially the 90-99 mr2/ 3sgte forum.
next was injectors. there is ALOT of confusion here, where to find them, what they look like, what size are they really ect.
what we're looking for is the MKIII N/A supra injectors. not turbo injectors, not alltrac injectors, N/A MKIII supra. theyre a lime green color, and 315cc. just to clear up another point of confusion, they do NOT become bigger injectors in our cars. the fuel pressure between the n/a supra and the 5s is the SAME.
there is a pic in the 5sfte sticky of what they look like and the flow tests to show it.
i found mine on ebay, but you can sometimes find them on some of the boards ive mentioned, and the supraforums.
also, i really reccomend having the injectors cleaned and balanced once you get them, if you look closley at the printout for my injectors in the sticky from when i had them cleaned and balanced, youll see why i say this.
one of my injectors wasnt even spraying, it was DRIPPING before it was cleaned. i'd HATE to see what would happen if i'd installed that thing in there and cranked up the boost!
so yea, i really cant stress enough, HAVE YOUR INJECTORS CLEANED BEFORE YOU INSTALL THEM!!! www.rceng.com did an excelent job on mine for about 100$, and ive heard thru the mr2 board that www.witchhunter.com also does a very good job, and are only 12$ per injector.

EDIT!!! 315CC injectors are TOO SMALL for use in a turbo 5sfe. 460cc rx7 injectors are a drop in replacement and are discribed later in this post!!!


you'll also need to upgrade your fuel pump, use the 255lph walboro supra pump. you can get it for under 100 usually on ebay., and pretty much bolts in.
next for me was the intercooler..now contrary to popular belief, bigger IS NOT always better when it comes to intercoolers.
you wanna choose the smallest intercooler to fit your needs, with a LITTLE room for growth. for instance, in my case, my goal is around 190-200whp for now, so i chose a intercooler thats 26x6x3 overall length, with endtanks. its good for up to 300hp. why not somthing bigger? well, the #1 reason is theres no NEED for anything bigger. lol the bigger you go, the more pressure drop you have, and thats not what we want. with all the piping invloved for a 5sfte FMIC, the last then we want is some big honking core, sucking up 2-3 or more psi of the boost we wanna get to our engines.
for the piping, again, bigger is NOT always better. 2" or 2.25 " is more than sufficent for us. you'll need to buy pre-bent lengths and cut and fit them for your particular setup. jcwhitney is cheap for aluminized steel, or burns stainless if you want stainless pipes.
then the noise maker of the bunch , the BOV...your choice here, i chose the HKS SSQV... got it from ebay for 190+ shipping i think it was..just make sure your buying the real thing if its from ebay, theres alot of shady copys floating around. youll also need a mounting flange to have welded to your intercooler piping, make sure you get the correct size and material to match your piping.
TOO BE CONTINUED...

I am not sure on boosted motors but seating rings under heavy initial load is common among many
good NA engine builders, my brother does it for a living and it is the prefered method of many.
After initial seating they obviously don't keep it up, they break them in similar to manufacture
suggestion. Glad to see it coming together Manny.

I look forward to an update everytime i get on 6gc (457482 times a day) and have been crushed each time for the last two days.

update please

lol
nothing really over the past couple days, just cleaned up the rest of the stuff for the motor, today after work i will finish buttoning it up, tommorow it goes back in the car.

motor is finally off the stand.
WOOT.

ill reinstall the clutch later today, dustin is comin by and we'll get the motor in and start buttoning her up.





and what i've been up to while waiting for parts to arrive:



look ma, no ABS!

why get rid of the ABS?

cause ive had dead sensors for years, i always hated the way the 94 system worked, its cheaper to remove than fix, and it cleans up the engine bay.

motor is in, pics later.

ahhh well i guess that makes sense then.

GOSH!!! Everything looks soo clean Manny.. I've got to get me one of those parts washers.

hey pressure? let me know how u removed your abs i want to do that too! but the motor is comin out really good! let us know how the drop in and start up is comin along..

Fcuk yeah - looks really nice P. Can't wait to see that dyno sheet with the new cams and CT-27

you need a non abs master cylinder, and then use toyodiy.com to compare the diffrences between the abs and non abs lines. there are like 5 or 6 lines that need to be changed, and there are also 2 splitters that are needed, one of them is actually discontinued from the dealer, i got lucky and one came in for me, even though it came back as a discontinued part.

a pic of the progress from yesterday, i havent had a chance to get out there today, ill get out there for a while tommorow and start refabbing up the oil lines again ect.

oil lines are set, axles ect are in...just a few more things and she'll be ready for fluids and then it'll be back up and runnin again.

Nice man. Cant wait to see it rolling again!!

for no more blue valve cover.

Everything else looks great though!!

Manny, don't you have a heat shield for that turbo?

yup, its just not installed yet.

solid

Get a Non-ABS master cylinder---#47201-2B090---about $175 (list is $260) from the dealer, I got Manny's from the junkyard for $15
Then some brake lines and splitters from the dealer, followed by the list price:
#47311-2B090 $14.80
#47311-2B120 $7.34
#47313-20700 $12.69
#47314-20590 $14.80
#47315-20640 $9.97
#47318-20350 $7.34
#47371-20540 $21.95 <---this is a T splitter that showed up as discontinued in the parts database, I had it ordered anyway and it came in directly from Japan
#90904-13009 $15.20

One of the lines wasn't necessary but I have no idea which one that was.

Looks like you'll be back up and running soon... Nice work!

I like the new spot for the oil filter much more then the old one.
How much does that whole relocation kit go for anyway? I wouldn't mind doing something like that on my 3s. I hate when I change my filter and all the oil gets all over the block.
