hey guys just wondering what kinda power you make out of gt3540/.50front housing and 1.06 rear internally gated or xr6 turbo ????

I dont think 350rwkw would be out of reach I think however you might have to modify the shaft on the gate to allow more boost. I made around 250rwkw on 10psi on one

generally 400rwkw @ 21 psi was the most that was pushed out of one at HPF.

sweet so 350rwkw seem promising thanks guys just curious about the internal waste gate holding this pressure how unstable will it be or should i weld it up and go external

They done a couple tests on the XR's and found with no cat and a high flowing exhaust that the internal gates had problems holding boost down. Not sure what its like on the VL's as there smaller engines. Maybe be ok, a lot of people use them so cant be to bad. If you were going to use external though you should just get rid of that one and get the external gate turbo. I think there about the same price.

Pretty sure they are cheaper just get a gate on the stock manifold or something.

ok guys now i know this turbo can give me the power i want ill tell you everything else i gettin done well the engine consists the block blue printed and bored too suit oversize acl forged pistons shot peened rods linished crank n1 oil pump oringed block steel headgasket arp head and bigend bolts and arp rod bolts head consist of just a major clean up and a little bit of porting cam is a stage 2 jpc with double valve spring every part of the engine is being balance a hienergy sump the race sump not the street sump im gunna get one of the the extreme turbo manifold and i have the turbo as i been asking about above xf throttle body on standard plenum 044 fuel pump and undercar surgetank still have not got injectors or fuel reg yet it will all being run by a plug and play wolf3d i want 350rwkw will this get me there ??? might be a few things i have missed but you get the idea

Why would you do this and then go for an internal gate? Whats the reason? You might as well go external gate and then you would push 350kw and have a better control over the boost level. Unless of course you allready have the turb.

i got the turbo really cheap
