5SFE to turbo
 

So I know this is mostly a honda and domestic forum but I know the general custom turbo talk that goes on here is universal. What I want to know is is there anyone here who has experience with a 5SFE swap or have any info on 5s limitations. I have done lots and lots of searching but everything I find is either a no longer working web page or just not what I'm looking for. I know the 5s is generally larger but at the same time under powered due to that lack of boost. At the same I know the 3s head can go on the 5s block when you drill in the water jackets for the water ports on the 3s head. Anywho,is there a list of stuff rolling around on some unkown webpage or possibly this forum for 5sfe boost does and don'ts ? O0 Thanks in advance

Re: 5SFE to turbo
 

seen a few boosted 5sfe but they don`t seems to last too well on 250ish hp.
you should look into mr2 forums regarding 5sfe / 3sgte / combine engine infos.

Re: 5SFE to turbo
 

just do it and learn from trial and error. then next time someone asks this question you can be the person to answer it.

just put a turbo on and start tuning... youll learn the limitations and weak points pretty quick.

Re: 5SFE to turbo
 

there is a guy here that turbos yotas... i beleive its snafu something...anyway, find him and ask away

toysareme is the other big toyota nut

Re: 5SFE to turbo
 

MR2oc.com has all the info on slapping a 3sgte head on a 5sfe block.

I'd just throw rods/pistons into the 5sfe and boost the bitch. Run something sexy for engine management, though.

Re: 5SFE to turbo
 

3sge has bigger ports and a hotter cam, i've got one sitting outside :)

Re: 5SFE to turbo
 

I had the same question (Ive got a 1991 Celica GT-S DD). Im just going to make some kind of log for it and use an old TE04H, Il let you know how it turns out.

Re: 5SFE to turbo
 

just stick a camary v6 in that mr2 and turbo that. It will haul. there is a "how to" guide in an SCC magazine somewhere.

Re: 5SFE to turbo
 

Why mess with a 3S or 5SFE or even a V6

Re: 5SFE to turbo
 

I've got a 3sgte manifold i can sell you for 45 plus shipping, better than a log.

Re: 5SFE to turbo
 

I was thinkig of that, but I thought there was some kind of issue with using the stock manifold and turbo from the 3SGTE on the 5SFE? If theres not, than it sounds good to me.. Would you mind posting a pic.. or sending me one U2U.

Down with Toyota....Honda FTW!!!!

Re: 5SFE to turbo
 

Been a while since I seen this thread,thanks for all the help though and I've done assloads or research since then. I figured I'd ask here since it's called "homemade" turbo and figured someone around here might have done it before.

Re: 5SFE to turbo
 

Yes, the 3s turbo mani will work on the 5s, but there's a couple of things you need to consider before you boost your 5s.

1. 5s uses a map sensor that doesnt like boost....
2. cranks are prone to cracking...or spinning rod bearings. Not in that order.
3. TPS is a three wire...which on toys means past half throttle...the ecu guesses its load maps. not good for boost....

If your serious about boosting it, build the bottom end, and run a standalone (megasquirt FTW).

The biggest thumbs up about the 5s is that they are so common (camry, mr2, celica) that you can blow it to hell one weekend and slap another back in and be out the next weekend to mop up at the street races.

Just so you know, both the 3vz and the 5vz twin cam V6's BOLT TO THE S TRANNY!!!! :y And were designed to be boosted to 10psi from TRD's supercharger kit. My friend Jim has a turbocharged 5vz in his n/a chasis mr2 that looks bone stock but absolutley halls ass. PM me and I can give you his cell # if your interested.

Re: 5SFE to turbo
 

Goodluck with the swap,shouldn't be too hard and remember no boosting past 8psi :).

Re: 5SFE to turbo
 

Too bad toyota didn't make more of the all-tracs. Those kicked so much ass.

Re: 5SFE to turbo
 

thats a clean ass celica, ive been looking for a 5th gen shell latley since my car is all beat to ---- now, it would be cheeper to swap my stuff over than to fix my car.

Re: 5SFE to turbo
 

:S :6 :y

Re: 5SFE to turbo
 

5sfe + turbo = kaboom


if you are serious about a build for a 5s block, you chose it right as it is a cast iron block nad is VERY stout. Build the bottom end with pistons, ESPECIALLY connecting rods, and a crank as well, you will be ok. However then the head tends to start having problems. If your going to turbo it, spend the money and do it right and put a 3s head on there. With the v6 5 spd tranny, you will be looking at some major hp figures.

also the max ive ever seen on a stock 5sfe engine is 200hp with some nice tuning. The head on it really does hold it back alot.

Re: 5SFE to turbo
 

NEGATIVE,

If anything the strongest part on the 5S block is the crank as it takes a hell of alot more of a beating then the motor can put out. As for the head it's actually not as bad as the people say it is,granted,the 5S ihead was designed more conservatively and in "STOCK FORM" will stop making power around 4.5k. The 3SGTE head on the other hand in "STOCK FORM" is good all the way till 7K. If you where to go through the effort of custom regrinds,supra valves,valves springs,and shims, you'd have a nice head.

Re: 5SFE to turbo
 

Il probably do a jihad (G head) swap somtime this summer since i found a decent donor car at a local wreckers, so iI can get the head wiring harness and ECU.

Re: 5SFE to turbo
 

The S-series cranks are fairly stout, not quite as beefy as a 4g63, but still nice. Make sure you have a competient machinist inpect your crank for hairline cracks. Also remember that S cranks are nititrided from the factory, and as such will become WEAKER if machined for oversized bearings. Basically, if its out of spec, chuck it in the trash can.

Re: 5SFE to turbo
 

Its notr super clean but its OK for DD duty. Basically its just slow as balls and heavy. Fantastic handling though..

Did you say you had a spare 3SGTE head??

Re: 5SFE to turbo
 

It is the very reason why I'm going with a V6 instead

Re: 5SFE to turbo
 

3sge

Re: 5SFE to turbo
 

Trust me, you will NOT be dissappointed!!!

VZ heads flow very well, and are overall a very well designed motor, some ppl believe that they are mechanically superior to the 2jz, with the exception of the pistons of course ;) Cams are the only big restriction in the motor, and I think they have a few options now too.

Re: 5SFE to turbo
 

Yeah I was reading on that and in reality the 3VZFE sounds (mechanically) alot like nissans VG30E motor with a few slight differences. My only problem is the fact that I am in Guam and everything here is WAY overpriced. So I will have to wait some time and get some meney saved up. It'll probably be another two or three months before I have enough money for the swap. O0
