4k engines and heads

[79rolla]

go to club-k
gueys there that are making as much power as a 4a on there... 4ks can handil quite alot from factory aswell and have a nice sound to them...
still wont get alot of cheep power out of them as they will still be a pushrod non cross flow motor... but hey... 4ks are cool

Doesn't take that much to make them rev a bit. 10k is a bit of work though lol

Yeah mine isnt even near that, and will be happy to 7700. I believe the maincaps are a weak point if you want to rev them really high.

Turbo one rips around past 8 before you know it, tacho runs out at 8 though

Oh yeah, outright revs I daresay mine will probably pull well over 8, but there wont be any power up there. I do wanna get a few k's out of it before I have to pull it down again, damn lack of chrome top rings
