JDM K20Z2 Motor Questions

[PetefromtheStreets]

Thanks for the reply..no, i didnt change the RRC rod as the size are bigger and cant be fitted into the stock k20z2 crank shaft..but the pistons are interchangeable..

Here's are my mod:
1. k20 cl7 cylinder head
2. k20 FD2r camshaft
3. k24a2 310cc injectors
4. RRC 11.7 CR pistons
5. RRC intake manifold & throttle body
6. Hondata flash pro
7. Fd2R 6 speed MT gearbox

My foreman told me it could make 200 whp or higher with higher RPM (>8k) but i was afraid as it might just blow out...well, after reading your post i'll stick to my current 7600 rpm..thanks guys...

Gotcha gotcha. Yea I would play it safe but im pretty sure you can make ~220ish whp with the mods you've listed. Even at only 7600rpm.

I really say it depends on bolt ons and how much air hes moving....... Im still at ~200whp at 7600rpm

But remember... He has RRC pistons

Idk from the test I've done with my car and compression ratio differences it is deff gonna help him but how much still depends on bolt ons/air flow. I'd give him the ~220whp range with a big boy intake/manifold and a big boy header/exhaust system but with off the self bolt ons that's a stretch. His weak point will deff be the rods though cause that's the same problem I have lol.
