just got my itb's in from ausy. now im debating what i should do. i want a full bridge port i think but i need some help. i would really like to push near 200hp with my n/a set up.


also where is the best place that people know of near or surrounding illinois for rx7 porting and tunning? thanks for the help.

 

we need more info

engine? 12a 13b? 4 port 6 port?

are you gonna overhaul the engine at the same time?

for a full bridge would be good to have 1 piece apex seals...

give us more info

budget?

 

You can do 200hp with a street port 13B (especially with a *good* independent setup) and it will be much more pleasant to drive.

 

With that said, you can get far more than 200hp with a full bridgeport, and as long as the car is not a daily driver you will learn drive it fine, and with fuel injection and ITB's its not even that bad. With minimal tuning on my full bridgeport ITB setup Ive got a car that idles at 1000rpm with reasonable low speed driveability. It cruises well and on the open road I get around 30mpg. And when you open up the throttle you will forget all about any driving issues and be glad you didnt get a streetport.

Just my 2 cents, far too many myths out there that bridgeports are not streetable.

 

Epitrochoidal - What standalone are you using for your ITB setup? I'm going to be rigging my E6X up to my setup...

 

Im using a megasquirt 2 with ms2/extra. Working like a charm so far. Im using an Alpha-N (TPS vs RPM) VE table to tune.

 

would I be able to achieve 200whp w/ a S4 6-port w/ a large street port, hayabusa ITB's w/ tuned length runners, and a tuned length collector? I would like the engine to peak around 8000rpm. This car will not be used for the street at all. Would I benefit from hogging out the 2nd and aux ports since the individual runners aren't divided going into the end plates anyway?

 

^ With full exhaust yeah
