is it ok to run a say gt35r on a rotary and not have the turbo working to hard. I heard a t3 flanged turbo cant move enough air on a rotary. I am going single and i want 375-450 whp without major lag (sorry sp sloppy dont have much time)

people run gt53's on these and make 375-400hp, it works, turbine is a little small though

do u know if they have hade cooling issues?

Personally I wouldn't run that turbo, however if you are set on it, atleast get the real T4 Turbine housing from Aspec-tuning.
