Looking at a turbo available in my area...

"It has a ported and polished inlet bell, polished intake housing, and comes with an adjustable wastegate.

A/R is .60/.63 Hot/Cold. "

He wants $350 neg.

At what kind of (ballpark) numbers would this become too small for a 87 6-port NA thats going to be rebuilt, maybe minor porting? Car needs to stay streetable, so I figured this may be a decent option... I know I'm leaving a lot of variables, but I've barely started in on the motor, so I haven't decided on aiming for anything! Open to suggestions, and lotsa info! thanks!

 

Too small, you'd be better off with a TII stocker.

I thought the stocker was around a T3 size? Must be my mistake. thanks!

 

a turbine that size would worry me on a rotary. my opinion: you'd be asking for trouble. stock turbo or maybe something like a 60-1.

 

Your tittle says t3/t4 which is a hybrid, t3 turbine and t4 compressor. The stocker's turbine is equivelant in size to a t3 and its compressor is yes close to a t4. The turbo you described even though you listed no trim levels I know already is too small due to the A/R values you listed (way too small turbine A/R regaurdless of the trim, and the compressor A/R although not as critical I know that only small trim compressors come with such a lame A/R, so its a small trim compressor). The answer is NO, its too small, let some Honda guy buy it.

yeah that thing would be better on a single cam civic or something

 

way too small.
