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 think a 35R single turbo is a perfect sized turbo for the rotary. it makes the majority of the power in the midrange and has both lower and top end as well when properly fitted.

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?

Yes...significantly bigger actually.

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!

"Is a 35r too big for a street port?"

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
