Hi my name is paul for all who dont no that already
I have bought a new turbo for my track car i am currently building and as a few no had bought a T4. I have desided now to got the GT route as people telling me that they spin up easlier than a T4. So at Nashional Day i bought this...






I no it is a GT28 which i wanted or a GT30 as i want about 450bhp.
The thing is that it has been modified the exhaust side has .57 and the GT28 i think has .64 or .67. quote me if i am wrong.
A couple of people have said that the exhaust side is that small that i might struggle makeing 450 bhp when others say it will, can anyone help me at all as i am a bit confussed. I thought that with it having a large compressor as in the pics and a smaller exhaust housing than the T4 that it would spin up earlier so less lag and still produce the same amount of boost i need I am confussed now. can someone help and explain in laymens terms PLEASE.

 

md240R I think
I have heard they surge there tits off
May be wrong tho cus i usually r

 

Hard to tell from the pics, but I reckon that might be a GT30.

The Turbine Housing does look a little small and might make it likely to surge.

Has the Turbine housing got 0.64 on it?

Tricky one though, from the pics.

 

it aint a gt30 ROFL,, md240r as my mate has one on his car
