Wow! WOW!!!!
Thanks a LOT for all that great information!!! I certainly didn't expect such a bountiful response to my questions. I want to thank everybody who responded, and I'm going to investigate all suggestions, because they ALL made lots of sense!!!
My partner in this, has several MoPar "toys," and I have a blown, V8 bracket car, myself, but we both wanted a new project, and it looks like it might happen. But, with all this new information, now, I'm not sure just what direction it will take. We'd never considered anything but a /6, and had initialy just thought of bolting a Buick GN "take-off" turbo onto a fairly stock 225 slant 6 and going from there... but, those 4-bangers make that idea look pretty lame.
FWIW, I have raced a potpourri of drag cars since 1956, and have never had one with a manual transmission, so a 904 was the first thing we agreed upon.
Now, I'm wondering how to go about bolting a 904 to an SRT-4 motor.
My partner in this venture is 72, and I am, 71, and neither of us has the faintest idea of what is involved in the details of dealing with EFI. My first reaction would be to remove the injection and go with something I do have a limited amount of experience with, a blow-thru carb setup of one kind or another, but my common sense tells me that that could be the dumbest thing I could do, so don't worry; that won't happen.
Before I waste any more of your time, he and I have to investigate the cost factor involved in there two possibilities. I'm on a "fixed" income, and it's not "fixed" very well...
We initially decided to make this a low-budget, junkyard-parts, experience, since we both already have bracket cars that we work on, constantly.... it was just going to be a low- budget exercise to give us some experience in turbocharging (some of my best frriends own Grand Nationals!!!)
But, now, that may be changing, with all this new information.
I want to thank you all again for the good info and advice! I KNEW this was the place for quality opinions and info I just couldn't get, elsewhere!! You guys didn't disappoint me!!!
I'll get back to you!
