HEAD bottom end CAMS

[CyccX]

Hi, on start i'm asking for patience.. I have few doubts..

I'm going to make hybrid R19, allready have bottom end from F7R and just rebulid them now.

1. Witch Head is better to use.

F7P from my old engine ?? (polished and matched)
or buy f7R head ?? (in F7R are bigger inlet valves.)

2. Witch cams you to recommend to this engine ??. Car is for daily drive, but i'd like to gain about 170 - 180 bhp

3. Witch ECU ?????? frome F7P,Williams,F7R ??

1, id personally use the F7R head if you can

2, myself i have catcams 225's and mine is in that region of power(depending which rr you use lol) last time mine was on a rr it made 175.5bhp/145 lb-ft torque

others have used there aswell and theres a few who have the piper versions making about the same power etc

3, doesnt really matter which ecu if there remapped properly, but try use a early 16v ecu or williams ecu as there no immobiliser on them(less to worry about)
