You can get just about as much HP with a BIG streetport than a bridgeport, and get better reliabilty and not as much porting. Just a thought. Buddy of mine gets 275 HP out of his 12a streetport at the flywheel.

with 48 IDA induction.

what do they do in street porting?



and once i have my engine out, were would i take it to get it street ported? and how much will it cost??

camocarl 01-30-2005 06:09 PM

If your not doing it yourself, in my opinon the best thing for you to do is just go buy a engine ready to go. Will be cheaper in the longrun. Carl

Buy an engine already built and sell parts of you other motor to help pay for it. Carl

rootbeerdragon 01-31-2005 05:40 PM

were would i start? and what gets streetported, another words what parts will i need off the street ported engine??

No offense, but you need to read around in the Rotary Engine Building&Porting section. All off these questions are already answered there.



Good luck with your decisions.
