I have been reading up alot on rx7club and np and i noticed alot of people say dont go full bridgeport on the street or even 1/2 saying i would regret the descision.



Now what changes? just less power down low?



I am looking to bridge my 20b and i would like to clear this up.

I have no experience with a half bridge, but general consensus from people who have driven them is that drivability is not that far removed from stock.



I do have experience with full bridge and peripheral port engines. The best way to visualize the problem is to imagine trying to accelerate gently from a stop, or to have a steady city-speed cruise. Simply put, with a full bridge engine... you can't. They do not run smoothly at all in the low load portion of the driving spectrum. You will have "assloads" of power down low, and you will have bucking and snorting, but not all that much in between.

Aux bridge = best of both worlds

Aux bridge sounds pretty difficult to set up.



I am going to look into the half some more since i figured the full would buck.

its better when you're accelerating or decelerating, but cruising under 4000-5000rpms it wants to buck

i drove a half bridge port single turbo FD on the street for about 2 years. It's not that bad, it is however, too god damned loud to be practical. IS this gonna be an NA 20b?

im strapping a gt4202r onto it



so no to the n/a https://www.nopistons.com/forums/pub...IR#>/smile.png



And the last thing im worried about is emissions and noise, those do not matter

I regret doing a 1/2 bridge...it's so damn noisy and draws too much unwanted attention for street use. I think a properly setup large street port is fine...Lupe/Eric/alias-of-the-day got 603rwhp on streetport, no dowels, and an HKS T51R.

Is there such a thing as a 1/4 bridge? I have been looking in to this for my next engine. I have the A-Spec 500R and a street port currently. With my Buddy Csub exhaust, it's quiet as a mouse even with a mid pipe! I love the brapidy brap https://www.nopistons.com/forums/pub...IR#>/smile.png ...and would like a higher red line. I hate to loose low end but as long as I have power before 4k I should be fine for the street but preferablt 3500 would be alot better. btw: does Judge Ito still buod engines?

Well if you have 4 inlet plates a half bridge would mean 2 of them are bridged so a 1/4 bridge would mean 1 plate would have a bridge. https://www.nopistons.com/forums/pub...1047683664.gif So No unless you want a bit of a Lumpy motor thats a pain it the rear to set up. LOL



You can of course get a Big extended port to Brap if the exhausts are big, that may be where you have seen a Mlld Brap.
