okay my 3sgte is going into my 6th generation celica...would my 98 5sfe go right into my 92 gt-s without mods?..thanks

The 92 GTS has the 5sfe engine right?(GT/ST have the 4afe I think)

As long as your 92 has a S-Series engine, it'll work.

yeah my 92 gts has the 5sfe...same as the 98 gt motor 5sfe.

you might have some wiring issues putting an OBD-II motor into an OBD-I chassis, but maybe you can still use the '92 5sfe ecu with the 98 5sfe longblock and tranny...

i mean do a complete swap...remove everything...switch ecu's and everything...that is okay tho right?

The GT has a 5sfe as well.

The 98 is OBDII. There are plenty of people here that will be able to tell you the various approaches that you can take regarding that issue.

no dont do that.

i sold my 98 OBD2 motor to presure2 and we put it in his 94 OBD1 car. to make it work, you have to swap a few small things over from your old obd1 car.

to make this motor work in your car, you have to :

use your 92 harness and ecu with the 98 motor.
swap over your 92 distributor onto the 98 motor.
swap over any small sensors that are on the 98 motor but dont want to plug into the 92 harness (i think we had to swap the egr sensor , o2 sensor and some exhaust temp sensor in the stock header/downpipe) .

if you do that, the motor should run perfectly in your 92 car

k cause i thought they both were 5sfe so it would be a complete just bolt on without problems...so now i need to swap some sensors?..weird...ok so is that it?...

k this means it would be a waste of time to swap then...so if im gonna do the 3sgte swap, might as well do the swap on the 92 gts then?...i really want it on the 95 celica gt but dang it im not gonna go through all that when i have to find some old 90-93 celica parts...

ok, now im confused as to what you are trying to do.

if you are swaping a 90-93 3sgte into your 6th gen, then you use the 3sgte harness, ecu and all the sensors that come on the 3sgte motor.

if you are swaping in a 98 5sfe to a 92 5sfe car, then you should keep the harness and ecu from the original 92 car, and take off some of your old sensors and misc stuff from your old 92 motor, as needed. really easy stuff, and you will have the sensors that you need on the old motor.

Word. I think you might be confused, because what lagos explained is very doable and straight forward. The only scraps will be the 98 sensors and ecu.

yeah i understood but tryin' to get a lil' more info.
here's the situation:

i have a 92 celica gts shell. still has ecu and some misc sensors (i think). the motor is blown. i also have a 95 celica gt with a 98 5sfe. now what im trying to do is swap the 98 5sfe into the 92 celica gts. so i can buy a 3sgte and put it into my 95 celica gt. that way i will have 2 running cars. i understand what you're saying lagos but can you tell me all the sensors or items i should keep for the 92?

so what you're sayin:

keep my 92 celica harness and ecu - goes with 98 motor/tranny
92 distributor goes with 98 motor
egr sensor, o2 sensor, exhaust temp sensor from 92 motor goes to 98 motor
what other sensors should i take out from 92 to go with 98 motor?
what do u mean by "swap over any small sensors that are on the 98 motor but don't want to plug into the 92 harness?" dont i need to plug it to work it?
let me know of other things i need to complete.

thanks lagos

what other sensors should i take out from 92 to go with 98 motor?

other then what i listed before,you shouldnt need any other sensors. if there happens to be any other sensor on the motor that i dont know about, then all you have to do is unscrew it from your old blown motor, and screw it into the 98. its VERY EASY.
oh, you can add the ignitor to the list of 92 parts to use. i know that the 98 ignitor will not plug into a 92 harness.



what do u mean by "swap over any small sensors that are on the 98 motor but don't want to plug into the 92 harness?" dont i need to plug it to work it?

ever sensor has its own harness plug already on it. each plug is "keyed", meaning that their shape is a little different so that you dont plug in the wrong wiring harness plug to the wrong sensor. if you find any sensors on the 98 that have keys that dont match up to the 92 harnes, then just replace the senor from your blown 92 motor into the 98 motor.

so the basic idea is. if you 92 car has a motor, ecu and wiring harness, then you should have no problems swaping in your 98 motor, because youll have any spare parts that you need on the blown 92 motor.

my 97 5sfe went into a 93 no problems... I just used the shortblock and head though....

Yeah, your idea of putting the 3sgte into the '95 Celica, then putting the '98 motor/tranny into the '92 shell, is very doable and fairly easy. You just have to do a little modding to the '98 motor to make it work right in the '92 chassis, but the mods aren't difficult at all.

btw - in case you don't know, the OBD-I and OBD-II things we're talking about is your emissions equipment and sensors. Hold on...I just had a thought...Did the '95 Celica come with OBD-I or OBD-II equipment? I thought the last year for OBD-I was '95. If that's true, then even though your '95 Celica has a '98 motor, it might already be modded for OBD-I, in which case, you might not need to do any of those mods...

Hmm...I'd find out for sure about that...

Or, you could just use the '92 ECU and do all those mods that Lagos talked about anyway, just to be sure it'll work...

Hope I didn't make you more confused.
