Gt42R 1.00 Hot Side.

[turbohead]

im looking at upgrading my turbo as im going external gate, and im thinking of going for the gt42r with 1.00 hot side. just need peoples opinions on if its to big for 350rwkw (till I get a built engine)

because aventualy I want over 450+ so the turbo side will all be finished, im just thinking of doing it once, but I dont know if its over kill for 350ish?

Nah it'll make 350 on low boost but it will be laggier than a stock turbo at the same power level... then when your ready for the 450+ wind up the boost.

Ive run a GT45R which is simiar on my old BA at 350kws for ages, the lag wasnt too bad.

Decide the power you want and choose a turbo suit, such as a 42, fit it all up and just run low boost until your ready for more power... easier and smarter to start with a bigger turbo and work up to it, rather than getting a smallish one, say T04z or similar and then eventually max it out and have to buy another turbo... again, then change oil water fittings ect again.

For 450-500 id look at a GT51R, which is smaller than the 42, but if you looking for 500-600 Id go for a 42, or if the coin is there, a gtx42.

The GT51R will spool quicker but not support as much max power as either Gt42 or GTX42.

The 51 has a 3.5inch inlet which makes it easier to build an intake for, compared to the 42s 5inch inlet... although a fabricated alloy 5inch intake does look horn!
