Hi all, looking for advice. I've got a spare low mileage engine I've been threating to build for years. I'm now going to have a lot more time soon so I want to start collecting the parts. Main advice I'm looking for is what Pistons and rods. Any other advice would be greatly appreciated. One other, I currently have a gt2864rs and was wondering what it flow, would I be using the potential of a forged engine or is it time for a turbo upgrade? Thanks all

I take it this is for 20vt rather than 16vt??
If so I don't know enough about 20vt's to advise but I do know if I was going forged I'd want to go with a turbo bigger than the one you have.... I'd say minimum turbo size I'd go for would be gt2871r.....,
If I were gonna buy a new complete turbo unit and not just upgrade one I had ( which you could do), I'd prob go for GTX3071r, a good mix of response and top end.... Apparently?!? ;0)

Yeah sorry it is a 20v, thanks

Not to sound silly but how do I upgrade my gt2864rs. It hasn't covered many miles and to be fair I have no idea on the pricing of them now. Thanks

I think that RS turbo can get you to 350bhp which can be done reliably on standard internals, so if you are going forged you might as well aim for 400bhp+, otherwise little point, hence the bigger turbo advice

I had a gt3071 on my Nissan 200sx mapped conservatively at 430bhp
