GT30R on RB20

[BLUEGTR]

A mate of mine was thinking of buying a gt30r .63 exhaust side and that is interally wastegated and he was wondering what it would be like on his rb 20. He is aiming for about 230-240rwkw.

Be a well matched turbo to that engine, a little on the large side maybe.

.63 might not take him up to 240, probably 220 if was to hazard a guess, but none the less the .63 will make it more responsive on the 2 litre.

.63 will give him 250rwkwsplus at 16psi on an rb25 , maybe 19 to 20psi on an rb20.

I don't think Garrett makes a .63 integrally gated exhaust housing for that Turbo / turbine .

I'd probably use a GT3071R or a GT2871R (a lil less laggy). They should both get you to your power targets.

Wont a properly sorted HKS 2530 make 230rwkws...if you want a bit more then go a HKS2535. If you want more headroom for later mods then cool go the bigger series turbo, but a reasonable punchy 230-240rwkws is heaps (To put it into perspective its way more power then a Porsche GT3:)).
