I have been reading on this forum and I have noticed some people are talking about an optional 1.32ar? Does garret make these to suit the turbo and does it still have the large exhuast outlet?

The car wont be driven everyday on the streets, only weekends.

I'm still waiting to see if anyone will know what power it will make on a stock 20b on 15psi.

 

I would say somewhere in the ballpark off 500 to 600 rwhp. Then again that's just a guess.

Thanks Alex, I found a 1.34ar for this turbo. That will suit me perfectly.

Thanks for all the info.

I will keep you posted on HP figures once its up and running.

 

Well you definetly have the turbo for your goal. Just hope everything turns out well for you in the tunning department!

I have a gt42 and red-rx7 yes the smaller gt42 might be out of your range but this gt42rs seems to sound large enough. Your more in the T81 or thumper range...

w/ the numbers 20b-3rotor got on the gt42 (i beleive he has the 53trim like me) @ 8psi it seems to be more then enough for the street. I plan on running 6-6.5 psi on street which i expect 350rwhp and about 240-250 ft/lbs at.

RED-rx7 w/ that engine you have i think you might see numbers around 700rwhp at 15psi (w/the gt42...gt42rs i dont know but i would expect it to have a flow rate of about 100-110lbs/min) ON YOUR 20B


so to answer the poster.. port the hell out of it and get 700ish at a bar (good guess)
keep it stock at get.... 575ish??? @a bar
maybe you'll get 400hp @ 8psi like 20b-3rotor (if you get tuned well) but you will spool a lil sooner w/ that dual BB turbo OR YOU BETTER FOR THE MONEY IT COSTS!
