Asking for thoughts and suggestions on turbo size, and type on a bone stock 98 jdm b18cr.
I have access to a t3/t4 ar57 will that be okay on a stock block if ran at low psi?

 

Low psi? Psi is meaningless give us a hp goal you would wish to hit

 

I would like to get 300 whp if poss on a stock block

 

Just search and find a turbo efficient in the 300whp range and do a quality install. Your tuner will run as much psi as is needed to reach your goal of 300whp. I am running 11.5psi with a GT3076R on a stock 97 spec B18CR makes low 300's at the wheels.

 

Nice thats what im looking for is 300whp. In a 88 hf that ought to be pretty fun. what do you think about using a t3/t4 578 trim. will that be over kill?
