Bridgeport NA guys check in...
Hey, I'm very serious about bridgeporting my NA while it's out. What were your first impressions about driveability? Any words of wisdom about anything you would have done different? Also, what injectors, ecu, etc are you running with this setup?

i was also wondering this. because if you have to run a diffrent ecu for a bridgeported n/a then i cant do it like i wanted 2. but if you can run all stock injectors and ecu and stuff then im freeking doing it! some one with some smafts chime in i want to know 2!

THe biggest problem with the stock ecu and usng a bridgeport is that the air flow meter is a HUGE killer of power. The stock afm is fully open well before redline on a stock ported engine. Without a free flowing intake, you'll have alot more exhaust dillution into the intake side of the engine. A good header with a very free flowing exhaust is also a must. While it can be done with a stock intake manifold, you will get far and away more power with an aftermarket manifold and a standalone ecu. As long as you have a stock ecu (no piggybacks either) forget about bridgeporting. Stick to streetports. If you are willing to change the intake manifold setup and ecu, go for it.

For AFM I'm not sure what you mean, with standalone you no longer HAVE an AFM.
For my current partial bridgeport project I will be using the stock ECU for break-in only, just because the port isn't going to be major, I wont have to tune while breaking in, and I wont be revving it up high anyways. After break-in is over, though, I'll be going with megasquirt for fuel and a distributor with MSD6AL for ignition, at least that's the plan for now.

Picking her up tommorow. Bridged on auxiliries, S4 Shortblock, s5 longblock accessories, harness, ecu, afm, smog equipment, ra rebuild. jacobs fc1000 ignition, huge vac leak and almost idles perfect at 900. And it has s5 TII secondaries.
-Andrew
Edit-I'll be throwing on my full rb exhaust and controlling it with my afc II. I think i'm going back to s4 though, i just think the s5 ecu isn't meant for my lower comp s4 block.

And I'm assuming you've kept the aux port actuators and sleeves intact? Well that's why it idles, with it closed you're not getting the massive overlap that comes with an open bridge at idle.

Is that ReZ311 old car? If so you got a great deal. You picked it up dirt cheap.

Here is some info of the car for people who don't know.

I don't think this info has entered the manual yet. There is an active discussion about it here:
http://www.msefi.com/viewtopic.php?t=7544
The general holdup is that the test car got into an accident a couple weeks ago, but they're still working on a scope until the car is fixed.

Sounds cool, I look forward to it. I'll probably change my mind between different types of porting another thousand times before I get it all apart and do it. It only really needs to be weekend driver streetable as I'll have a MX-6 DD. Tryin to keep it in the family

For a person who just graduated high school and only owns 1 rotary, a stock one at that, I don't think you have any room to say who knows anything about rotaries. I started rebuilding rotaries when you were in the 4th grade and I hardly have experience compared to others out there. Chances are that out of the 2 of us, I'm not the one with the problem.
