Is a 35r too big for a street ported motor.
Looking to pick up a 93 street ported rx7 with a aspec 35r kit. Is a 35r to big for a street port? Would it be too laggy? Ill get more info on the a/r of the turbo. But is a 35 generally speaking to big for a street port.

I have one on my car (GT3574R) and it is street ported. Typically porting helped the turbo spool faster, not slower. |
Is the BWS366 larger than the gt35r?

Borg Warner S362 has a similar size compressor to the GT35R with a larger turbine. |
I had my 35r on a streetport 12a.. It is t4 hot side (Turblown stage V)and I still very quick spool times. I only ran off the gate spring. 7/8 psi.... Gate was fully open before 3 grand... in high gears around 2500 if memory serves me correctly... 13b street port will be even quicker!

welcome to rotary world. since the rotary needs 30% more air than a piston engine to make similar power the math is different w re to turbos. turbos for the rotary come in 3 relative sizes small medium large. small is GT35, BW S300 62 and the compressor area is approx 6.3 square inches average medium is Garrett TO4Z, GT500, S363, PT67. compressor area 7 sq inches large is GT4094r, GT4294, BW S366, BW S475 and compressor area is approx 8 sq inches small is around 450/475 max medium is around 550 max large is 600+ obviously there are additional turbos and hp numbers can be plus or minus but it is a good way to start the fitting process. the GT35 is an excellent turbo for many rotary app and A-Spec is a respected vendor. good luck, howard |
I'd like to possibly put down 500whp on pump I'm assuming 35r could possibly get those numbers

I don't know if you have read Howard's post #6, or, simply don't understand it. Your answer is their.
