Wow Steve, you've really let yourself down... :P

Made a little progress today. Wen't around looking for some slim fans, and the cheapest I could source was $99.99!!?! What?! So, I busted out my handy-dandy hand-saw, and started shredding into my stock radiator fan. No pics, but I got it to fit! Only a few things left to do. Intercooler and piping w/BOV, oil feed/return, and fluids and a belt. Then it will be boost, for me. The rest of this week will likely show no progress, but I hope to be finished before the end of next week, assuming shipping of miscellaneous things doesn't bend me over

BLAAST

at the junk yard, looking through all the used rad fans, You'll see that some factory fans are way thin and they will certainly sell them for under 50$.

haha neat!

props man

I like it. It's somthing different.

MAF's work just fine with boost. If any thing they do a better job of metering air then a MAP sensor can.

Both of my turbo Escorts still use a MAF sensor, and they both run great. One has even seen 20psi.

I'll see how long the "modified" stocker will work out...

Thanks Luke XD

I'm sure the MAF sensor is just fine, but I'm led to believe that the Megasquirt doesn't like it much. We'll see how it works out. I'll be running the car at 7PSI on upgraded injectors alone, leaving the rest to the MAF, dual O2s, other all-inclusive sensors, and the ECU. I guess that's one advantage of OBDII. It's not the greatest, but it is reliable for a street setup. And if all works out well, I won't be running like that for long anyway.

I doubt this car will see 20PSI, but if I happened to stumble upon a spare motor, it would be fun to tear into it and see what could be beefed up. This "A5" motor is supposed to be loosely based off Mazda's "B6". I know that the "B6" also came as a -T, so there might be something there.

Completely unrelated, but I also share a front suspension entirely identical to the Ford Festiva. With all the V8 projects out there for those little egg-cars, there's some really sturdy suspension gear out there. Furthermore, if I'm not mistaken, the Festiva is the pre-predecessor of the Rio. The Festiva was, revamped if you will, as the Aspire, which is the distant cousin of the Rio. So, there may be some Mazda/Ford capatability out there worth looking into, as far as motors are concerned.

If all your going for is 7psi, going to a standalone is a waste of time, money and energy.
Just slap a FMU on there and call it good. I have a hard time beliving the factory fuel system can keep up with 7psi with no engine managment. Sure I belive you that some guy some where did it and it worked, but I bet it was pinging like a **** and running lean.

Is'nt your motor based of the mazda bp and not the b6?

7PSI isn't the endgame, only the first tourist attraction! Basically, the ECU has a limit on how much extra fuel it is burning, (not just running rich, but cumbusting) and it ends up being pretty near 7PSI. The turbo I got is actuated at 7PSI, so that's just a magic number for a first stage in the setup.

Once it's all up and running, the 19# injectors will be replaced with 30# ones, and the standalone will be installed. From then, it's turn up the boost and tune, until things break. Fix the things that break, and try again. I'm not talking about putting it to 12PSI, romping on it for a week, turning it up to 15, yadda yadda. I really plan on turning it up notch by notch, and maybe sitting on it for months at a time. Not going for any world records, or break-neck trap speeds here. Just trying to see what I can do. If the (2) guys that ran setups similiar to mine experienced pinging and lean conditions, the lie about it tooth and nail. But, 7PSI on the stock computer isn't the endgame, just a staging point while I wait for the standalone. And oh by the way, it's a direct plug into the stock harness, tuneable on a laptop on the street, and will cost me less than $300 bucks. So no, it's not a waste of money, time (well not mine anyways, but the guy who's assembling it yeah) and energy I'm not quite sure about. 4 10MM bolts probably will take less than 200 calories to take off and put back on, so I'll eat an extra cheeseburger and still net some energy for sex later that night

And yeah, it may be the BP, now that you mention it. It's been a long while since I've discussed it with the real gear heads that figured most of this stuff out, but yeah, BP; I think you are right.

I know a guy with a turbo'd tiburon gt (the earlier ugly ones w/4 headlights) that was running off stock injectors and maf. He swore that it was good to 5psi (what he was running) until he got additional injectors. He beat on it all the time and from what i know its still running

NethercuttML2

Believe it or not, the 19# injectors ARE NOT stock...

I'm sure this setup will work well enough to use as a commuter until the standalone is done. I have no doubts in my mind, in fact...
