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 !

Addressing the clutch, the S54 Transmission (what your GT has) has a different number of splines on the input shaft than the E series transmissions that come on the 3S-GTE’s, so you need a 3S-GTE flywheel, 3S disc with 5S splines, and a 3S pressure plate. If you call Southbend Clutch and tell them what you have, they’ll make the clutch you need. However, always use the OEM Toyota throwout bearing. It seems like the aftermarket ones always fail. A lot of people run an F1 Racing lightweight flywheel from eBay with no issues. You will also need a Walbro 255 lph fuel pump or a Supra TT fuel pump. The stock GT fuel pump cannot keep up with the 3S. As far as the intercooler goes, you have a couple of options. You can use the stock 4th gen top mount intercooler but you will need to cut a hole in your hood and use an aftermarket hood scoop, or you’ll have to replace the top mount intercooler with a front mount. The 3rd gen 3S-GTE’s use a water to air intercooler so no hood scoop or front mount is necessary, but the 4th gen uses an air to air intercooler which was fed by a hood scoop on the Caldina. The intercooler would have no air flow in a Celica though.
