6G Celicas Forums

hi guys i'm new to this forum and am looking for help with a project of mine so any help would be much appreciated.

START READING FROM PARAGRAPH TWO IF IN A RUSH

So here it is I brought my first car from an auction over a year ago now and all I knew about it was that it needed a new clutch and cambelt. I didn't even drive the car before I brought it (rookie move i know but payed off). so the car has been a real pleasure to own. i'm loving the way it drives, sounds and looks. but recently while giving it a bit of a heavy foot and hard shifting i have blown my gearbox. so being the young 19 year old i am i went out and brought a turbo engine for it at the same time.

So i have brought a full engine loom and ecu out of a st215 caldina (3sgte) and i know that it will bolt straight in (i think) thats the easy part the problem i kow im going to have is the wiring. so what im looking for from you guys is any tips and other probems im going to run innto. also if any body has a wiring digram from a st202 3sge celica and one from a st215 3sgte caldina that would be much apriated. before any of you guys try and say ive chosen too big of a job the sort of person i am will not let it get on top of me and i am planning on trying to get this done before my summer brake in about 4 months. i am training to become a auto eletrictian so have access to plenty of peole to help but am wanting to do as much on my own as possble.

also if i can get any recomidation on other upgrades which would suite this build well would be helpfull. such as coil overs, brakes and gearboxs. j

you shouldnt have to do much to the body harness. just compare the ST202 and ST215 wiring diagrams. it should be fairly similar to 3rd gen. with more wires. since 4th gen has COP and more sensors

Sorry I've never herd of COP what is that. I'm planning on getting both looms a merging them into one. I was taking to one guy and he said I might have problems with speedo rpm and coolant temp. he also said that I'm going to need and after market fuel pressure regulator. do you know where i could find a wiring diagram

google is your best friend. search, read threads on people that have done same swap.

the tachometer, is not a problem. there are solutions. (digital tach adapter)

COP ----> Coil On Plug

Why aftermarket fuel pressure regulator. need to be more specific. Celica has a return fuel style system, not sure if the 215 motor is the same. easternpiro has one, and he can help

i wasnt sure why i would need one apparently when he had finished his swap he was having the injectors going full on start up so it would be hard starting and lots of black smoke but i will have to see when i get mine don

did he do his swap on a celica?

fuel pressure regulator has nothing to do with that

yeah same swap. I thought it was a odd thing to need to change but i think I will be fine with the swap will let you guys know how it goes it should be all completed with in a couple of months

hey guys ive been trying to find out weather or not my fuel pump in my st202 will be allright in the st215 engine any ideas

Your fuel pump was a 190 lph pump when it was new, and it's now aged. The 3S-GTE will need a 250 lph pump.

hey thanks for the replay i can get a fuel pump from work thats a walbro one which is 246 lph for a decent price which should do the trick

hey guys quick question. you guys might know or be able t point me in the right direction. when I got my engine i also got a new gearbox but its come out of a st206 curren 3sfe is this going to be weaker than my 3sge st202 gearbox. will it still bolt straight in

they both should be s-54, unless youve got a E series tranny..

hey guys im further into my build things are coming along nicely. was starting to look at buying my front mount so started taking measurements and trying to work out how to route it and was wondering if anybody else has tried front mounting their Celica looks like its going be a bit of a squeeze
