He has even taken every class Jake Raby teaches about the M96/M97 motor. Heck he might have even taught Jake a thing or two as he's been working on Porsche motors for decades. Anyway, he tried putting a 2.7 in a 2.5 car. He ended up getting it to run but I believe he had to put the 2.5 heads, wiring harness and intake on the 2.7 motor and it still kept throwing codes. I'm not sure how much farther he's gotten with it though. He was doing it for fun. On another note, you're not going to see much of an improvement with a 2.7. That's a lot of work and $$ for little gain.

Jake began working on Porsche engine's when he was 12.
