Want to increase boost - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Hi,

I'm running a R33 GTR... pretty standard currently running about 350Bhp, i've had the car a year and I really want some more power.. my brief spec is as follows

Rebuilt engine
Hks Filters
Tomei 1.2mm steel head gasket
ACL big end shells
Standard ceramic turbos running 0.8 bar.

Is there any way I can squeeze more power out without spending a fortune on new turbos, and if so what can I expect.. Would I see a big difference running 1 bar??
Also if I put a boost controller on and run 1 bar, is there any chance of det? would I need mapping?

Thanks

No it will be ok, but it would be advisable to get a 1bar chip from someome like RK tuning/abbey or buy a mines or similar ecu.

1 Bar chip? would I also need a boost controller to change it to 1 bar, or would the chip do that..? what sort of cost am i looking at?

What about putting on some nice downpipes and a nice free flowing exhaust system? You don't mention this in your spec so I assume yours are stock.
