Hey guys i have a b18c, integra engien i min Civic Ek4, there is making about 260 Crank Horse Power on stock, sleeves. The engien spec list is:

Wiseco pistons 13:0 in kompression
I beam Light wait rods.
Walbro 255lph pumpe
RC Engineering 440cc
Jenvey 48mm throttel bodies
Blox Racing Cam gears
Hytech manifold,
Skunk 2 pro 2cams.
Supertech titanium retaniers, and springs.

But i am going for more power, so i am thinking about going from Skunk2 Pro 2 Cams, to skunk 2 pro 3cams.
But here is my question: I am afraid of the sleevs is going to crack, i am runing 9300rpm right now, and i really doesn't want to run higher Rpmīs.
So will i get any gains of the Pro 3cams? Or do you "guys" have other ideas for cams?

I am doing a lot of drag racing So i think high end power is good.

I'm sorry if my English is not too good. I come from Denmark.

Your current cylinderbore is what? And have you calculate this CR, it is actual? Wisecos shelfpistons with 8.3cc dome? Also, is that header real custom made Hytech or just eBay-copy? I'm sorry, but you leave lot of questions in air .

What i think, in this point you can net some gains with properly made headwork and header. If they haven't already made for this setup. But bigger is not always better.

Regular (RON)98E? It is equivalent for US pump 93. Have you tried something else fuel, like E85?

I apologize also my english.
