non-tuneable street port ?
I was wondering if it would be possible to have a street port and 4 850's along with aftermarket exhaust, air intake and a boost controller, yet no haltech, PFC, ect. ?. would it be possible to get it to run safely(no boom)?

would it be possible to hold off on the injectors? or would the modifications still be too much for the ECU?. I can't get a PFC right now, so I'm trying to find a way to get it driveable without wasting money on a piggyback system.

Yes, i did for a few weeks. If you don't have a boost gauge get one. intake & exhaust is often a recipe for boost creep and your stock ecu will *not* compensate for it.
I wouldn't try to extract any fun out of the car until you have stand-alone. -That is to say don't be stupid. The car isn't going to spontaneously explode but it's not prepared for your mods. The PFC was my greatest bang for the buck improvement. I imagine other computers are similar.
EDIT: You don't have a midpipe do you?

I figure I have to baby it for the first 500 miles anyway(new port job). I Had a T2 done up the same before and went the S-AFC way. I don't want to go that route this time. I figure by the time I do the 500 miles I will be able to get a PFC installed and tuned. I'm just trying to find out if it is possible to drive it like it is till the seals are seated.

It's possible, without the 850cc primaries. it's very much so not advisable though. As well, if you have the engine out right now, it'd be a real pain in the *** to install the injectors after the motor's been put back in.
do it right, do it once.
where's East Petersburg? I've heard of it, but can't place where that is exactly. I'm in Mohnton.

Wow, seriously errant advice in this thread. There is no reason to need larger injectors with that setup whatsoever. Just run the stock injectors and a boost controller to keep boost at 10 psi. Do NOT run a midpipe.
If you're planning on a full exhaust later, then you should port the wastegate while the engine's out.

So you're saying that at 10PSI, with stock injectors, aftermarket intake and exhaust, and a street port, the car will be fine to boost with stock ECU? I've never heard anyone say that before.
I also didn't comment on his large primaries, because he didn't ask if they were too much for the setup he has.
Of course, I'm no mechanic, I just know what I learn from the forum and people I meet on the forum(basically tons of people to contradict one another)

I don't know if Wade's site is still up, but there was testing done to show that the stock ECU could support bolt-on mods at 10 PSI.
