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...

You got that thing in/out and rebuilt really quickly bro. props.

just less crap on the motor.
i also deleted the a/c idle up valve, PS idleup valve, and the VSV's attached to the back of the intake manifold.


didnt seem like it to me..lol
waiting on parts sucks, and having to work 1-2hrs at a time made things take alot longer than it really should have.

changed the oil this am (100miles) and will again @ 250, then switch back to synthetic @ 500.

Good plan. Whenever i do things like this people say I'm obsessive

icic...

changed the oil yesterday @ 270miles, just about no metal at all in it, which is good.
a note to guys with relocation kits.
if your using the trans-dapt relocation peice for the filter side of your setup, dont ever use penzoil filters.
since i am breaking in the motor, i am using dino oil, and penzoil happen to be on sale at the local advance auto.
so, i picked up oil and a filter for 15$, and did the oil change, figuring "hell, its only gonna be on there for ~150miles, why waste a toyota filter for that?!"
started the car up, and had 0 oil pressure. after a bit of cursing, and checking things out, i switched back to the toyota filter that was on there previously, started the car, and had perfect pressure again.
hrm...damn penzoil filter must be defective or somthing!
other than that, all is well so far.
i was hoping to have enough miles on the car to hit the dyno before the CSP meet, but it dont look like that is going to happen.
oh well, a few more weeks and i'll be ready to go, i've already got the itch like crazy! i have to keep convincing myself the engine isnt ready yet!!! haha

How much more power with this beast have? Also will you be running more boost than before?

Good to hear the motor is running well Manny

I only use OEM filters

im not really sure. we'll just have to see when i hit the dyno.
no plans right now to run any more boost than i have in the past.

thanks jim.

i normally run toyota filters as well, just happen to use the penzoil cause it was basicly free, and i didnt have another clean toyota filter in the garage at the time.

P - it's because ALL toyota filters use a check valve to keep oil ready to go into the motor on startup - some/most aftermarket ones do not.
Bet you don't do that again

no no, d, this wasnt a no oil pressure on startup, followed by oil pressure thing, this was ZERO oil pressure...like none. check valve or not, within a few seconds you should have full pressure at the gauge. when i didnt after 10+ seconds, i wasnt about to let it continue to run to find out if it would ever come up..lol

and no, i dont normally, and will never again use a penzoil, or any aftermarket filter.

Im new here and have been doing some research but i just wanted to know what work would need to be done on an 180k mile 5sfe to prepare it for a turbo?

check compression, fix any leaks. if the engine is healthy, just boost it!

What should the compression be on the 5sfe?

spec: 178 PSI or more
minimum pressure: 142 PSI
difference between each cylinder: 14 PSI or less

remember to fully open the throttle while cranking.

come on guys, lets keep non related stuff in seperate threads, this thing is long enough for the noobs to sort thru as it is.

we finally made it over to the dyno today

set it up, and let her rip.

just to sum up the changes since the last dyno, we've added:

webcams "294" grind
fidanza LW flywheel
2.5"intercooler piping
26X12X3 intercooler
devils own water injection
and the emanage ultimate.
once i got things going, i set up the map clamp on the emanage ultimate, i cranked up the boost alittle and this is what it gave us.
once again, we used a 50/50 mix of 93 pump and 110 sunoco race fuel.



more comparison charts to come later.

damn, nice numbers there bud, now go and battle those 3sgtes. haha

the O.G. stepping up to the plate yet again to show them 3sgtes who's boss.

Damn, 200ft-lbs under 300. Impressive.
Got a lot of Wheel spin ?
