Then you could put one of these on it.

Than an RB30DE with ITBs?

FFS dudes. Thread needs to die now.

It is a shitty idea, there are hundreds of better engines out there that will have better throttle response and make more power NA with no mods needed.

RBs are great with forced induction, NA with cams they will always be inferior to large capacity NA motors such as a 4L six or a 5L+ v8. The later will also be cheaper as it will need no modifications, just the engine mount/transmission modifications.

You failed three times in as many lines skins.

I will be building a 25/30 non-turbo twin cam with custom ITBs utilizing the bottom half of the manifold. POSSIBLY bodging with some VG30 throttle bodies.

Then I'll be ripping out my 25DET and building that to awesome spec.

Rolls, I don't want to make that much power out of it... enough to have fun while I build other engine. Thats it.

edit: maybe a VQ30...

A 2ltr N/A 6 will never compare to a six cylinder twice it's capacity. Don't forget the RB is quite old technology noe too.

Ltr for ltr I can vouch for ITB's working on an RB20, this year I won my class (1600cc- 2000cc) for the second year in a row. I went ITB's because they are cheaper than three Webbers, although I'd probably get more power from the carb's, nothing worng with them if you know how to tune them.
