25/30 Cam Options

[WHITER33GTS-T]

Ive just finished my 25/30 and had it on the rollers. Currently it has Tomei 256 cams, Tomei springs and a ported head. The head was off my old RB25 that burnt a piston. After its run on the dyno with 20psi to 8000rpm (first big rev) It has started to rattle in the top end (to much clearance)

My tuner has said to change to a solid lifter setup and some bigger cams.

How big is to big??? Am thinking about Tomei Procams 270 10.25

Who is running a solid lifter setup and what brands are best to use?

This is how it went.

Also that is thru a C4 auto and running a Garrett T51r

well ull definately need to go solids for more cam

i'd send the head over to will @ jhh in brisbane to do the solid lifter conversion. then also talk to him about cam selection, however he'd recommend something around the 270 10.5 or even bigger for that turbo

if money wasnt a big concern, i'd also lookat puttin 1mm valves in the exhaust side, ull also need some big springs

Thanks for the info. It seems like he is the man to see.

Has anyone else had work done by JHH??
