[dyno305]

Hi everyone im a new member and im glad to see i have finally found some true celica fans from around the world ..... I got a few questions that i need to solve,I have a usdm celica gt automatic everybody knows it comes with the 5s-fe engine but i always wanted more power so ive been looking into buying a 3s-ge its the ideal engine for me i have found a couple of them on ebay im mostly looking for automatics. but all the ones ive found have the ecu wireing harness cut off do u guys no of anybody or anywhere that sells the harness or maybe somewhere i can get a 3sge with the ecu and its harness together i dont want to go through the pain of connecting all those cables. ohh and one last thing are there parts outhere for this engine? thank you

On a side note, I tend to agree with Czwalga and Kaos, a 3sge motor swap (non beams) is a worthy investment. When we're talking 40-50 hp increase for 500-700$, that really isn't bad. Think about it, we're discussing a group buy on some Colt Cams for the 5s. Change the cams = $400 , SAFC=$100, dyno time to tune it right = $50-100 So by the time you've done that, you've got $600 or so in a motor and only gained 35hp? Granted 35 hp off of one modification is very substantial, and there are obvious work advantages in not having to remove the engine etc etc..... but if you can do your own work, for around the same cost you can have ~10-20 more hp and it's bone stock....

Dyno305- I'm not going to say "hey, go read the stickies" - but I will say go to the my project section of this forum and just start reading. Read through Richee3's thread, read through czwalga's thread, read through greendemon's thread, read through S8S8's thread, read through my thread, read through anything and everything presure2 has written, read through everything that Batman722 has written and you'll learn more than you ever thought possible.

It took me hours and days to go through post by post.... and when you do you'll find out things that will answer your questions

i.e. 3sgte can mount to a 5sfe stock transmission, the S-54... infact all S-series engines can mount to the S-54. if you want a beefier tranny, get an e-153 (really only used with the 3sgte).
You'll find you don't have to remove the dash to do a motor swap, just the glove box and some small panels near the floor....

FINALLY- I am going to tell you that I'm getting the vibe that you are relatively new to modding cars. I came to this conclusion because you want to keep the automatic etc. So i'm going to assume that if you want to do a motor swap, you'll end up paying someone else to do it. And if you are going to pay someone else to do it, it's going to be cheaper to swap out cams and get a tune, than to swap out a whole motor because it all comes down to labor labor labor.

So I would recommend to you, unless you have all kinds of experience here, to start with the cams, we have a 400$ group buy of the best cams for the 5s in the works, and you should see what that does for you. IMO(in my opinion) that's the best thing you could do for yourself..... right now that is.
