hey guys this will sound like a silly question, but I was wondering what improvements can be made to a standard vf 35 turbo in terms of improving flow and or running higher boost more efficiently as i am new to all this? my turbo currently runs at around 22 psi and I have been told that it is very close to max efficiency for these turbos.....can they be high flowed?

yes they can be high flowed.

you can port it, coat it and create a hybrid using vf34 and vf35 parts.

i may be completely wrong, but i think stace got 330ps at the hubs using a vf35. confirm / deny?

better.

get a vf30 p18 housing and bolt it on. Bigger exhaust housing will give you a decent improvement on your top end over the stock p15 housing.

You wont be able to use a vf34 exhaust housing though as it comes off a ball bearing core vf turbo. you will need to stick to thrust bearing core vf turbos.

vf35, vf30, vf37

ok kool thanks for tha advice....just i'm just trying all avenues of making around 300 hp at the hubs before having to go to a front mount as i have enough trouble with the police as it is....( got yellowed on Fri night for exhaust being too loud.) so I am on the lookout for modifications which can make power but are relatively un noticeable...

get a decent twin tip rear muffler. Looks stock and will quieten down the exhaust considerable without restricting power.
