Have a local guy who has a complete setup from a JDM Evo 6.5.... engine, transmission,turbo, ect. 61,xxx on parts. COMPLETE. And he's giving me a good deal on it. My current motor is around 130k, not showing any signs of going anytime soon... but having a complete setup is my garage waiting for DDAY wouldn't hurt my feelings any. ESPECIALLY at such a good buy. I know, I know... save the "build it!! MOAR POWER!! blah blah...." I've come to the conclusion that at my power level (425/400) and the way I drive... that stock motor and tranny are all I need and I don't want the hassle of a built motor.

So, my question is will the engine and transmission from a 6.5 bolt right in to my Evo 8 or will it take any modifications? Also will all my parts like cams and internals also swap right in? Lastly, will the ecu and wiring from my 8 work with the 6.5 motor? Thanks

The engine should fit, but I don't think the transmission would. You could install the engine with the 8 tranny. The 6 turbo is almost identical to the 8's, it would be a nice bonus if the the turbo is the 6.5 RS version (HRA), it's such a fast spooler, check the turbo's number it would end with '560'

I would end up selling the turbo, as this is indeed out of a Tommi Makinen 6.5... it's the tdo5hra-15gk2-10.5t turbo and only has 61k on it. Would sell the transmission too then and just have shep rebuild my 8 tranny if it ever goes. But the motor will bolt right in, which is what I was hoping for. Anyone know if there would be any downside to running a this motor in my 8? Personally, I think I'm gonna do the swap JUST BECAUSE it's the closest I'll get to an Evo 6 here in the states.

Yes, the motor should bolt right in, no downside that I can think of, providing the engine is in a good shape. 15gk2 is the GSR turbo which has a 65mm compressor, the RS turbo is 16g6 with larger 68mm comp, but still both are great in spooling due to the titanium wheels. Is your 8 tranny 6 or 5 speed? If your tranny needs rebuilding, the 6 & 8 share many internals such as sync rings & sleeves, so you could use those for the rebuild.

A friend of mine who's a good mechanic just told me that the 6s tranny would also fit in the 8!

I really thought it would, the bell housing and mounts look identical.

Yeh it all should fit.... There will be little differences tho... Like alt belt is shorter, cam sensor bolt and intake mani has no egr etc
