3sgte 4th gen swap, Hello I am trying to swap my Toyota Celica 97 gt to a 3sgte 4th gen Options

I have the 3sgte 4th gen engine on the way and getting things ready to go! Looking for help and ways to get it going ! Right now I have done alot of research and talked to tons of people. I was wondering if I could get some help with my project . Right now I'm planning on running the engine stock I made sure it came with the 3sgte hanress and ecu and im getting a flywheel and clutch kit . Iv been looking around and doing research and I might attempt my wiring harness myself I have two harnesses and I might just try it . But I also need help from people that have experience with the swap and the 6gen community. Helping me find parts, and help me get it on the road with a wonder build ! I hope this goes well , would appreciate all the help I can get !

The clutch setup can be confusing, so I’ll try to explain it a little better. The flywheel bolts up to your crankshaft, so it needs to be for the 3S, not the 5S. The pressure plate bolts to the flywheel, so once again it needs to be 3S specific, not 5S. The clutch dish has splines in the center that the trans input shaft slide into, but most 5S/S54 discs won’t hold the power of the 3S, so most people run a hybrid disc which is a 3S disc with 5S splines. South end makes this disc pretty frequently and they are familiar with it, where most companies you call will not be willing to make a one off hybrid disc. South end clutches are modified Exedy clutches, very good stuff. As for the throwout bearing, stick to OEM. As Hardhead stated above, the aftermarket TOB’s tend to fail pretty early on.

The clutch setup I have mentioned here is not your only option. Feel free to search the forum to see what other members have used. I’m just referencing what I’ve seen most 3S swaps use.
