high flowing turbo. worth doing?

[handyandy]

hi guys, i'm thinking of hi-flowing my stock turbo on my r33 is it worth it? should i buy a 2535 instead? i have stock internals with boost gauge and tap brass button clutch pod filter bov, with fmic and safc just around the corner. will i need to do internal engine work if i want my car to last with a high-flowed or larger turbo? if so what should be done? :wassup:

i'm not always a hoon just when some punk in a commondore thinks he's the shit.

Depends on what power you are after, 230rwkw???? you really don't need internal work but then again it depends on how much power you are chasing.

Have you done the exhaust yet? Dump-front, cat and cat back.

Have a search this topic has been covered a few times.

thanks craz0, i have done the exhaust and will consider how many rwkw i am going to chase. :Bang:

Lager turbo doesnt really mean a rebuild.

You wont need internal upgrade unless u want to run over 13/14 psi

With a good manegment eg. PFC or E - manage that is turned properly with a bit more fuel and proper timing to avoid pining ( every car is diferent some ping erly some ping less, depends on condition of ur engine ) your car will last, i would suggest 0.8mm gap for ur plugs aswell so u dont puf and pop under boost.

Like craz0 said dumb pipe and exhaust system is essiential.

Make sure u have all ur gear in (fmic ect) b4 having a lager turbo as air flow is much higher i would also suggest a z32 afm as some tend to max out and cause cut outs.

But again it all depends on how far u want to go with ur power.

You won't need to touch the internals for just a hiflow (which are capable of 250-260rwkw with the right supporting components).

Their is about a thread a week on 'hiflows' so do a search for GCG. Also take a look (within the GCG threads) for info from 'Sydneykid' about his R34GTT with a hiflowed turbo.
