I was just wondering how much of a power increase you get from each type of port?

https://www.nopistons.com/forums/pub...1047683621.gif i am having my engine (88 se 13b) rebuit i have 2mm atkins aviation seals with a bridge port how much boost could i run with out blowing my engine if it is tuned right?

how much power? well, your bridgeport will net you tons of power top end, and some loss down low.



How much boost? depends on your fuel system.

Is it a n/a 6 port engine? Just curious b/c you said it was a 13B out of a SE...

yes it is a n/a 6 port. so i will have alot of top end how much of a hp difference do you think there is?i am thinking of going with 550's & 1600 255 pump with a af meter and s-afc

as for low end you think it would be a good idea to run nitrous to pull of the line just before the turbo kicks in?

FrostRacing 09-07-2003 12:57 PM

o yea the turbo i am referring to is the t3/t4 i will be adding soon

I think you need to build the motor and get it tuned with just the turbo before you even mention nitrous..

Why not save for a EMS? Be alot safer and not that much more than piggyback crap and other things you'll get. Find a used E6k or a Microtech lt8 or something.

yea i think that would be a better idea i just am not all that great with wiring and tuning who would i need to talk to if i get stuck? so while im waiting how much boost could the stock fuel system hold and when i get the ems how well would the internals hold up?

So you are gonna run 2 of those right? If you plan on running that HONDA turbo on a bridge port, all you are going to accomplish is making a little breep breep noise and a slow car. That turbo is way to small for a rotary much less a bridge.
