I recently did a compression test on my 25 and number 6 was low.
I have pulled the engine down and it has Tomei cams and Tomei forged pistons. The rest of the engine internally was totally stock.
The engine made 399rwkw on 17psi and had redline at 8200 using twin T3/T4 turbos, Greddy plenum, 1000cc injectors, splitfire coils, and Haltech E11v2 blah blah blah.
Everything else is like brand new except for number 6 piston. Even the bore is fine.
I will have to measure up the piston but is there anywhere I can buy just 1 Tomei piston just to fix it up. I am currently getting a 3lt bottom end built so just want to fix the 25 to throw in something later down the track.
Cheers
