Hey Johnny5,
Your V4 TypeR turbo should be a VF28.
as for V3 UK car i don't know but it wont be a VF
probarly a TD0 ?????.
When i say should be the VF, they are a weeker turbo and it's
common for them to blow and be replaced.
So find out what turbo's they actually are.
A VF28 is good for 280BHP with quicker spool up times than
say a TD04 which is also good for 280BHP but alot stronger.
If you can get a bigger Turbo like the Hybrid ones AndyF sells
and you'll see a big differnce.
Niall.
