this is for any turbo guru out there 
if you was going for a pair of turbos for a 700/800 bhp or more which would you chose
and with what size compressor wheel and size turbo housing would you go for

PassionFord Post Whore!!
what engine though?! a 1300 motorbike engine!? or a viper v10?!
all depends on what revs and boost youre gonna have to run. on a viper, a pair of T3s would probably make 700bhp on about 10psi. on a small engine, you need bigger exhuast housings to be able to rev the fucker high enough to make the power, and obviously a compressor man enough to chuck enough boost in.

PassionFord Post Whore!!
so its on a v8?!
if the rest of the engines been worked dude id imagine you'd only need a pair of fettled T3s!! stg three kind of spec, 360 thrust bearing, maybe a bigger zorst housing....
im not expert though
just what id sugest with my relativly limited knowledge!

Pair of T34 wouldnt be too bad to be honest in principle, but it all dependson the VE of the engine, and rpm you would be doing.
How much boost do you need to flow 800bhp on your engine?
You need to know that to cross reference it to a compressor map to find a turbo that wants to flow 35-40 lbs at that boost level.

ITs about rpm + capacity + boost mate, its not just T34=5500rpm, it is in a cossie at 25psi, but it wont be on a 7 litre v8 at 10 psi, that why you need to give more details before anyoen can be useful.
Two huge turbos like GT42's seems very over the top, as its going to be laggier than two GT30R's which would do the job just as well at that level.
But ONLY if they are on their compressor map at the boost you want, and you still havent said what that is so no one can help!
More details needed, a lot more details!
What CR is it?
What boost are you going to need?
What volume is it?
