6G Celicas Forums

Just to inform you, i embarked on the project with all of the components required but didnt really feel the need to list them here because as you say, its basic knowledge.
If i had blindly gone into it i wouldnt of been able to bypass fault code 54 either would i?
You missed off IAT, and it works fine on my old Tps.
All running on the St205 ecu, my problem was loose connections in the repinned harness.
Now making a set up for charge cooling the Mr2

Hi guys, so im converting my Mr2 turbo rev1 to use an ST205 Ecu.
I made a patch cable so i could swap back if needed.
Started up first time then wouldnt idle, did this a couple times.
Got fault code 21, expected as im using the old 1 wire lambda.

Then i revved a bit more, while still, and got a string of fault codes, 21, 22 24, maybe 26, and another which i missed as i got distracted not 54 as ive already done the resistor mod for the charge cooler stuff.

Pretty certain my patch cable is correct.
Then i decide start the car again, turn key and de-immobilise (toad alarm) and the three engine lights etc dont come on, and it doesnt even do anything when i turn the key? Weird as i didnt change anything.

Swapped back to old ecu and started fine.

So i thinking that my lambda needs to be swapped for 21 and would that of caused it to run rich and give 26? And wrong lambda might if caused the no idle?
But the water temp is in same place as on the Mr2 so that should of been fine? (Coolant temp?) So not sure why 22.

And my IAT, 24, the one i have looks exact same as the engine bay temp sensor with same connection? Is that correct?

Thanks all,
Dan
(ps. I used to have a celica, should of kept it)

haha no worries man yea i guessed it was more than just the compression ratio but just wondering whether or not it is feasable really. i read that link from rusty now and aye it looks complex haha
Cheeers

Another question, would either of those ECU's be ok to use on my 3gse as it is?

thanks man i'll give that a read, and i didnt realise that with the ECU so i'll look into a new one, im not worried about insurance either im getting it fairly cheap at the minute so will just hope it doesnt treble in cost haha.
Thanks for that mate

Hello, please someone shoot me i know i probably shouldnt be asking this but i cant really seem to find any solid info on the subject.

Basically i have a gen6 3S-GE (97 plate Celica GT) not a Beams unfortunately, its an st202, engine which i would like to convert to a 3S-GTE. According to wikipedia (yes i know the most reliable source in the world?) the 3SGTE engine is basically the 3SGE engine with a lower compression ratio and a turbo.
So how can i convert my 3SGE into a 3SGTE? how do i lower the compression ratio and/or just make the engine work with the turbo without causing excessive engine wear etc?

im expecting it to be expensive as n/a to turbo is but is it possible to do? I feel that the engine is good any finding a GT4 has seemed neigh on impossible to be honest.

If not possible without spending thousands of £££s what upgrades can be recommended? Im intending on a complete remap already.

Would aftermarket fuel pump and fuel injectors make a noticeable difference?

Nitrous? i looked into this but i'm not sure i would want to refill every 20 shots to be honest.

Also what about superchargers? ive read into them partially and i have a feeling they aint very good for your engine? Sort of the same as a turbo i guess but not so easily fitted for a reliable quick car im assuming?

Thanks for anyone that does reply and give me a couple tips, im not very engine orientated to be honest but i likey fast cars. Im expecting to do most fitment work myself however or get my cuz to give me a hand so labour aint an issue, thanks again.

Hey ekan thanks a bunch thats perfect

ok nice one man, guessing its easy enough to do? Cheeeers

Hey guys sorry im an idiot, as far as i can tell it is straight swap[ sorry i cant delete the topic

Hey guys, probably a stupid question but i was wondering is the GT4 front bumper and bonnet a straight swap onto the GT version? Also is there anything else, other than the spoiler, that is different in the trim of the GT4 and GT? The GT4 front just looks so much nicer
Cheers Dan

Hey guys thanks for the info, at least i know it would be harder than i thought, im not all that experienced with modding cars to be honest. Im gonna get the Ecu remapped for now that will have to do

Hey this has probably been discussed before but i havnt had any luck finding it, is it worth changing the S54 tranny on my Celica GT to the Celica ST tranny C52?
Also can this even be done (im assuming it can)

Ratios are:
C52 - 3.166, 1.904, 1.310, 0.969, 0.815
S54 - 3.285, 1.960, 1.322, 1.028, 0.820

Not alot of difference but was wondering, if it is possible to swap these, whether the accel difference would be noticeable?

Celica is GT basically standard just alloys, exhaust and short ram.
Remap Ecu at some point soon, is chipping the Ecu the same thing?

Cheers guys, Dan
