Gotta some questions for you guys.

When you street port a motor, what needs to be adjusted on the car if anything, specifically the idle??
Will the car run rich with a street port?
How do you lean a rich running motor?

Any advice???

I would think to really tune your engine to work good with your port you would need a stand alone computer. Something like a Haltech or an SDS unit(my personal favorite, its inexpensive and does everything I need it to do).

how much does the computer, a/f digital gauge, and injector controller run for all together?

You can run ported on stock computer
I would guess some fuel upgrades would be necessary.

SDS is realy a nice little computer and i've used there product in the past. Just wish they would have some type of spark managment. CJ

Like higher volume injectors? Or what?

My car is in my sig-
Without some of the mods, I would be fine with the stock fuel system, but with everything else I have, and more things to come, (hehehe- evil grin....) I am leaning out at high RPMS.
If you stick to just intake, exhaust, and a port, you should be OK, but 550 CC secondaries might be a good idea
I have a TII fuel pump and 4 550 cc injectors waiting to go in, just have to get a fuel computer. S-AFC, I don't want my mileage to go down more than it is.
Mild port on a series 4/5 engine only adds about 15% more power.

What kinda 1/4 times do you get?

The computer, sensors, controller and wiring harness cost about $800 +/-. This is a true stand alone unit meaning you don't have to have a laptop computer to make changes to it. The hand held controller is easy to use. Since the SDS EM-3 D doesn't control ignition you need to convert your car to electronic distributor from an 81-85 12A. It sounds a little backwards to put distributor on a fuel injected 13B but it works very good. A used distributor and some new coils will cost $100 give or take some.
