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 !

I did a 4th gen 3sgte last winter and it is awesome! I am guessing you got the motor from a supplier who imports them. For piece of mind I did the following to freshen up the motor:
1. Crankshaft seal rear
2. PCV grommet
3. Valve cover gaskets
4. Water pump and gasket
5. Timing belt - Sun brand
6. Timing belt tensioner
7. Thermostat and gasket
8. Spark plugs
9. Lower timing idler
​10. Oil pump o-ring and seal
11. Camshaft Seals
12. Convert to 3 inch cat-less downpipe
13. Light weight flywheel
14. Axle Seals
15. Magnet Oil Pan plug
You can get all those parts from PrimeMR2.com. Stick to OEM parts as much as possible. I know most of these companies say that the motor has less than 60k miles on it but unless they show you the original odometer, how do you know for sure. I lost my first 3s due to it being a worn out motor so an engine freshen up will never hurt.

For the intercooler, I started with an air to air intercooler and I was having engine heat issues because it blocked the radiator. I think part of the problem is due to the hot, high elevation climate I live in. Here are some pics of the air to air setup.


I now have a water to air intercooler and I love it. Here are some pics of the water to air set up.


The air to air is cheaper but the intercooler piping can be tricky. The water to air was more expensive but it really cleaned up my engine bay.

As for the wiring, I sent it out to WireGap. It cost me $500, I sent him my 5s and my 3s wiring and he combined them into 1 plug-n-play system. He is so detailed that he even put the clip on where the wiring attaches to the motor. It looks almost stock. He provides connections for you to plug in a tach adapter and will even provide power and ground for an intercooler water pump on request. Save yourself the headache and let the pros do the work for you.

Like they stated above, you need a 3s flywheel, 3s pressure plate, 5s clutch disk, and 5s throwout bearing. I will emphasize to get an OEM throwout bearing. Most of these clutch kits come with Chinese knockoff bearings that die after 2k miles. Mine did and it sucked to have to replace that with the motor in the car.

I have hit almost every problem possible with my swap some due to bad luck and some due to not listening to all the knowledge on this forum. The rule I learned the hard way was the cheapest way is almost always not the best way.
