I am planning on running twin TO4S turbos. I have AR .70 O-trim exhaust sides. I have a big side port. Are these housings to big??

No idea. Maybe get ahold of Fulltuned7. He works down at Border, and we all know they have experience with that type of crazy ****. https://www.nopistons.com/forums/pub...DIR#>/wink.png

Yeah, thats too big. I would go with .56 A/R

You are on the small island just go see chris (Dragon) he will help you out with your rotary questions.

Something tells me he already knows Dragon https://www.nopistons.com/forums/pub...DIR#>/wink.png

That is correct. We share a shop.



If they were P trim I would run .58's, but they're O trim. I currently have a 67-1 w/P trim 1.15. I don't care if the boost comes in late, as long as when I shift, the car doesn't come out of boost/power.



I'm not one of those GT 35/40 rotary chokers!!!!!

my bad https://www.nopistons.com/forums/pub...1047683664.gif

Why don't you just run twin GT 35/40's... https://www.nopistons.com/forums/pub...1047683329.gif two of those little exaust housings and wheels almost = enough volume to make some real Horse Power..

Twin TD025's would produce much more usable power https://www.nopistons.com/forums/pub...1047683329.gif

Maybe on a Honda!!!!
