Rb20det 250kw

[black sky]

Hi guys

Yea yea i know this has been done to death but every time i do a search on it i don't find exactlly what i want. so here goes.

At the moment my car is making 241.3rwkw at 17psi with the good old rb20det, it has a t3/t4 ebay turbo on it which i must admit am very happy with (best $320 i've spent on that car) but it kicks in at full boost a little over 4500rpm.

So what i'm after is a turbo that will make the same power or above but make full boost somewhere between 3500-4000 rpm and when i say full boos i mean 17psi. I also want the turbo to be able to make that power without turning up the boost more than 18psi.

I've got a gt30bb turbo which is about to go in it's a .64 rear housing and is rated at 500hp now can anyone give me a definate answer of when it'll kick into full boost and what psi will i be making 240 to 250rwkw. Cause if it's to laggy i'll sell it and get another one.

so people post up and tell me which turbo best suits my application. I don't mind lag but i feel like i'm waiting an eternity if it slightly bogs down in 1st.

mods that relate to the turbo are a

SS manifold

Tial wastegate

3 inch Zorst with highflow cat

airfilter running of a map sensor

and all the other suporting mods to get the power

Cheers
