What's the max output of stock t2 turbo? and at what psi? what's the name(maker) of the stock turbo?

 

It is a hitatchi turbo.. there are 2 different versions..


The 86-88 and the 89-91... Now, the 89-91 have more potential..


They can do about 11Psi and about 225RWHP

Does the size of turbo matter?

For example the mitsubishi td05 (Big) 16g for eclipses is a lot smaller (compressor and turbine) yet its rated to 370+ at the flywheel?

 

um, Like i said there are 2 turbos that came in the second gen RX-7

the 87-88 ( well i put 86 last time which was a typo.. no 86 TII)
and the 89-91



The 89+ turbo is good for ~225 RWHP@11Psi

You can go more than 11psi on the stock S4 turbo I thought. People on here have gone as far as 15psi that I have heard of.

I think all that depends on alot of things(ported wastegate/fmic/etc).

 

You'll get differing opinions, depending on who you talk to.&nbsp My experience have limited use to about 15psi; anything more would compromise the oil seal on the stock turbo.&nbsp At this boost, 250bhp at the flywheel is about it's max.
