Turbo Mini Forums

I don’t think anyone would say get a 12g295 anymore, too rare, too expensive.

I’ve never liked the 12G940 on small bores because of the valve/block risk (and pocketing looks janky to my unprofessional eyes). Along with the valve sizes being too big in most cases but that will depend on the cam you use.

Many of the 998 builds on here start with a CAM4810 because it’s cheap and is a good enough starting point, my own build included.


When you’ve got all the bugs ironed out on a simple setup (because turbo conversions never go to plan) then start to look at what to change.
