What changes need to be made for a streetport?
I tried searching but I can't find what I'm looking for.
With a street port using stock twins that are rebuilt to be a bit better, is there anything that needs to be changed?
Don't changes need to be made to the ecu? If so, what exactly and how would I go about doing that?

I drove around with a stock ECU for over a couple of years with a mild streetport. I just made sure that my boost stayed at 10 psi MAX.
So off the top of my head I don't think there is anything you *really* need to change. *But* to be on the safe side, and because you are going with a streetport (not a mild Streetport) I suggest you get yourself a wideband A/F gauge to make sure you aren't leaning out during WOT runs. If you are then you really need an ECU.
Note that you aren't really taking advantage of the port job if stay stock.

There is no point in getting a streetport unless you are going with a full exhaust. A streetport hurts low end torque slightly and shifts the powerband up a bit -- right where the stock turbos and cat start killing off the power.
That being said, if you plan on modding the car quite a bit down the line, it would be best to go ahead and do that now (obviously).

Well I don't plan on modding the car much. I just got a rebuild from Atkins rotary, they asked if I wanted a street port and I said no but they gave me a street port anyways.
So isntead of bothering with sending it back and waiting all this time, I just need to know what to do to make it run right with the street port.
And I think it's just a mild street port.

To get the most of the port job, primarily you should upgrade to a full exhaust set up. Catback, MP, DP that way your exhaust can flow much easier (no more bottle neck). Upgrading to a real CAI and an aftermarket IC, will lower you intake temps. which = more oxygen = more power.
A car with a Mild Streetport, CAI, Upgraded IC, DP, MP, Catback @10 psi has quite a bit more RWHP (around 260-280, all depending on how good is the setup) than a full on stock car @ 10 psi (220 - 230 RWHP).
The ECU is only needed for higher boost levels (creep or spike). As far as runing higher boost: A car with all of these aftermaket mods responds much better than a stock mild streetported car with only an ECU upgrade. For obvious reasons.

I'm just going to drag up an old topic on this one.
I plan on getting a Large Street Ported Engine (soon)
What I need to know is if I can run it with out any danger on the stock ECU, or should I just wait till I have a PFC to install the motor.
it said earlier that a mild street port may require raising the idle a bit, but could a large street port on a stock ECU (with out tuning) cause it to blow?
I have more modifications in plan, but the motor purchase is what I am dealing with now.
Thanks

with a serious port and the stock ecu, but if it was my car I wouldnt run it without the power fc.

Thanks, I'm actually sitting on a set of turbos that are slightly leaking oil.
(I assume this will be okay for break in period, due to the little extra oil that will be blow through the motor)
A PFC is in the works, but the motor is too good of a deal to pass up right now.

Yes, wait for those turbos to get converted, they were not just leaking internally, but externally as well. I was going through a quart every 50 miles on them. Not to mention the R&R of the twins...
