my 5SFTE turbo project, 300+whp PG 23!!!!!!! Options

[presure2]

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 very sorry to hear this Manny, BUT I eagerly await the build thread! I am sure it will be a very worth while and informative read to say the least. And from the ashes will rise a Phoenix.......owwwwww I can only IMAGINE!

Any details on the build.....?

nothing set in stone yet, jimbo, we're still in the process of figuring out what the next step will be from here.

once we get the details sorted, ill be sure to post up the plan of attack..lol

[SeverX13]

sorry to hear that manny.


You will have one badass phoenix after she arises

[Smaay]

oh no, i feel your pain Manny. hopefully its just a ring land. i wouldnt drive the car untill its fixed. if you are grooving a cylinder wall you dont want to make it worse.

[Followtheornghat]

sounds like hes gonna have to rebuild the motor.. (rings and such.) to get the compression back to normal and retune it.

[presure2]

thanks guys.

damn...i really do know i shouldnt drive it...but the car still hauls a$$...lol jenn took dustin for a ride yesterday, so he could see the smoking...even he was impressed by how hard it pulls..thats the only ride we've taken since i did the tests over the weekend, im trying to hold off driving it. although...i am STILL pondering just saying screw it and going to the dyno anyway..lmao..

[jcaron9gt4]

dooooo itttttttt. You're going to be building the motor anyways.

[6strngs]

do it! it should last a few more pulls. just drive it very conservatively on your way to the dyno and have a trailer ready just in case it blows on the dyno.

lol, i live 5 blocks from the dyno...AAA gold FTW!

[DEATH]

Dude - very sorry to hear that. Look at it this way tho bro - you already proved what can be done on a stock block - maybe this was the kick in the ass to build the block and get stupid with it?
Anyway you go I know it'll be better tan it was before - LMK if you need any parts.

[Defgeph]

Damn that's crazy. I know you'll get her back on her feet.

[d0w0rkS0n]

oh damn... well... dyno it! lol lets see what she does...

[presure2]

got the motor ready to come out last night, its sitting on 2 mounts right now, im about to go out and put the 3s on a dolly so i can use the engine stand for the 5s.

with the help of a few of you, i smartend up and decided against dynoing this motor, but i WILL be dynoing dustins 5s, if for nothing else than to clean up the tune for his motor,..but no 15+psi runs..lol, i dont think that motor could take it, its got 160k on it.

pics in a while.

[x_itchy_b_x]

ouch sorry to hear man. let me know if you need a hand.

[6strngs]

will you be putting the cams into dustin's 5s before the dyno? or are you going to leave the cams in the 98 engine?

[BBoYRuGGeD]

oh damn...wonder how much harder it woulda pulled if the compression held + tuning...hmmmm

-bboy

[presure2]

6strings:
i will be installing the cams back into dustins motor.

b-boy: agreed, it was definetly much faster than before, after tuning and driving shannons car, and jims, im guessing that it was easily all of 270whp, and at least 300+ftlbs. the thing pulled like a rocketship to redline..lol

i didnt get nearly as much done as i wanted to yesterday, the baby kinda had a cranky day so i wasnt able to spend any real time in the garage.
all i managed to do was get the 3s off the stand, and finish pulling the 5s.
i want to get the 5s on a stand today, and start getting the turbo kit and stuff off.



on a good note, at least i can finish painting my engine bay. lol

[playr158]

so i guess we know one of the 5sfe motor limits!

Sorry to hear it did blow on you, but good to hear you aren't going to abuse it further.

good luck on the restoration.

[Smaay]

it looks like you pulled the power steering pump off with the engine. any reason you do that over leaving it on the car and not openeing the system?

PS fluid is cheap, easy to refill, and the banjo bolt crush washer is like 2$...lol
i just hate messing with the PS in the car, im lazy like that.
