I have a slightly messed up, yet fairly good looking '90 celica. The previous owner decided to "repair" it before taking it to auction. The car is an st184 with a 5s-fe mounted to the auto trans from an st, and the motor has so much blowbye that if the oil cap is opened while the car is running that you get a face full of oil(no small amount). The motor also leaks oil badly.

I plan to rebuild the motor this summer with new seals and rings at minimum and, since i'm taking my summer term for school off to work and rebuild, I may as well have a bit of fun while im at it.

A few of the things I had planned(this year and next...and the next...etc.):
1.Rebuild/rebuild with turbocharging/swap
2.Auto-to-manual conversion
3.7th gen/short shifter kit
4.water meth inj. kit(with turbo)
5.afc(with turbo)
6.piggyback ecu and tune(with turbo)
7.begin the process of acquiring a life if I have time

I've been constantly told that the 5s is tough, and read that the rods are forged. Is this true? Would it be worth turboing and tuning the 5s after a rebuild, or should i just go spend my time in the junkyards looking for a 3s swap(constantly praying in find it before my mr2 obsessed friend)

Thanks

Got nothing to do with blowby. You'll get a face full even with a new engine. Remember that's where you fill oil and with cam shaft rotating it'll throw oil everywhere.

1.Rebuild/rebuild with turbocharging/swap
2.Auto-to-manual conversion
Do the above together unless you really enjoy taking engine out of the car.

3.7th gen/short shifter kit
Don't even think it'll fit. Why not get a 5th gen short shifter

4.water meth inj. kit(with turbo)
5.afc(with turbo)
6.piggyback ecu and tune(with turbo)
Get a full aftermarket ECU.

No it isn't. The ST celica had a 4afe motor and the transmission will not attach in any way to the 5sfe.

and the motor has so much blowbye that if the oil cap is opened while the car is running that you get a face full of oil(no small amount). The motor also leaks oil badly.

All of that is normal. It's not blow-by as Pineapple said, that's a very rare occurence on a naturally aspirated motor. And yes... old toyota motors leak oil. From everywhere. You're probably leaking power steering fluid as well. You're leaking oil out of the valve cover gasket (in the back) and the oil pan gasket, and more than likely the rear main seal.

I plan to rebuild the motor this summer with new seals and rings at minimum and, since i'm taking my summer term for school off to work and rebuild, I may as well have a bit of fun while im at it.

I agree.... FUN!

A few of the things I had planned(this year and next...and the next...etc.):
1.Rebuild/rebuild with turbocharging/swap

You have a 1990, has a "rev1" motor with no knock sensor. Don't boost it, you'll regret it, unless you do it right with a built motor and a standalone.

2.Auto-to-manual conversion

Can't go wrong there

3.7th gen/short shifter kit

You COULD do that.... A stock 7th gen shifter can be made to fit in the 5th gen. Personally, i'd just order a TWM kit. Or cut down your stock shifter. OR (easiest way) swap to a 92-93 shifter, they're shorter than 90-91, and feel great.

4.water meth inj. kit(with turbo)

Meh. I guess that's one way to try to control a knock.

5.afc(with turbo)
6.piggyback ecu and tune(with turbo)

This is kindof redundant.

If you're power hungry.... then swap a 3sgte or a v6 in that thing. You CAN make power with the 5sfe, but it's WAY easier to start with a 92+ model year. Yes... the rods AND pistons are forged. However, the rod bolts are tiny and weak. It sucks.

If you want a cheap built bottom end, you get your 5sfe crank machined to fit 3sgte rods, and attach some 3sgte pistons in there. With new bearings and rings to go along, you've just built a 400+whp capable block for under $1000.

If it isnt the trans from a 4afe we have just proven that the local shop owner is a moron. I replaced one half shaft last year, but went to have the other side installed this year by someone else because of time constraints. He told us that the axle that I brought him wouldnt fit. The idea that the trans had been swapped seemed to fit(the previous owner did a full engine/trans swap as well as many other things and screwed about 75% of it up). It should be possible to swap in a different trans with a custom conversion plate, not easy though.

Would the 3s pistons actually work? If I remember, 3s pistons are 86mm while 5s are 87(im not much on internals, most of my previous work has been full engine/trans swapping since it's usually faster and cheaper than rebuilding).

The 7th gen shifter can be swapped in, but you have to do some minor cutting to make it fit.

Not only would a water/meth kit help control knock, it also allows increased boost(cool intake charge), increases octane to something along the lines of 111, and helps remove carbon deposites.

The only real problems with leaking i have are around the oil pan gasket and distributor. My power steering doesnt leak at all, and the rear of the motor is as clean as I've ever seen.

The 3mz swap would be mean, but would also take a while considering I need to learn to weld for the mounts >_<

It seems the solution would be to drag the motor out of a 92-99 model and build it separately, buy a 3s, or just sell the thing and be done with it.

I should honestly get over the sentimental value of the car and go buy a s14 and save for a 2jz swap kit.

you could say that...about 80+ texts a day about how to improve downforce, decrease weight, improve power, and hide no2 bottles in various cars.

Lucky you. My last motor was as leaky as a tour bus full of senior citizens at the Taco Bell drive-thru.

Where are you located in Indy?

As for the bore, you are correct. Stock bore 3sgte is 86mm, stock bore 5sfe is 87. You MAY be able to fit the 3sgte rods to the 5sfe pistons, but i cannot confirm that. If you could, i would go that route, as the 5sfe pistons are not the weak point of the motor. Otherwise, you can get some 87.5mm aftermarket 3sgte pistons and plop them in there, leaving enough room to make sure you get a smooth cylinder wall.

As for dragging the motor out of a rev2 car... you'll need the whole thing. Wiring harness/ecu included. The motor itself is no different other than slight cam difference and lack of knock sensor. The main difference is in tuning and ecu.

I'm 100% positive you don't have a 4afe tranny.

PM me where in Indy you are, i wouldn't mind coming out to take a look at the car and we can talk from there.

 

[yellowcel]

not actually in indy, all the way down in seymour(probably junk civic capital of the state).

As for the rev2, is the cam more aggressive and by how much? I assume it's probably obd2. The motor has been swapped, but im not sure which gen it is from though I assume it's from a 5th or 6th seeing as it supposedly only had 110k miles at the time of the swap. I'll check to see whether I can find a sensor or not when I get time saturday(hurrah for getting 40 hours in four days each week). I'll probably have a pic of the piece of junk in my sig soon(prepare to go blind), and if it isnt a 4afe trans I'm going to kill that mechanic seeing as I have the axle sitting at the foot of my bed until I get time to fix it.

I hate to ask so many questions, but knowledge recessionproof, so expect more.

Rev2 cams are slightly more agressive, you'll pick up about 5hp from swapping those in.

92-93 rev2 is still obd1.

buy my 91 gt all the parts are there you could rebuild my 5sfe while being able to drive yours its a man trans with twm shortshifter and all the parts you could need all there

you know you could take some pictures and we could tell you which motor you have. and @ asphalt victory i'd think he'd wanna get rid of the rev1 5sfe not get another one.
