stand alone fuel injection
stand alone fuel injection hey guys...well i got my project car..94 lt1 trans am. it has no motor or trans..the wire harness and ecu is still there.i was originally going to try and source a used lt1 and rebuild it to handle a hefty shot.but since i have no accessories by the time i bought a used setup with all accessories,then rebuilt it and bought new heads,.injectors..etc..etc..i would have so much money in it i could have prob built a bad a$$ smallblock..SO here is my plan. i want to build a sbc to put in it. Forged bottom end with all top end goodies..i then want to add a fuel injection system with abot a 200 shot.my plan is to get 500 horse without the spray. i have been looking and looking at aftermarket fuel injection kits. so far i have looked at the accell and holley..i really like the holley stealth ram setup but dont know if it would clear the cowl on the firebird..i could cut it if needed but dont wont to cut the window. i need suggestions on a system..i see some of you run the accel dfi setup.hows that work for your? i cant seem to find much info on these systems..i also need suggestions on rotating assmeblys..i have been looking at the scat assmeblys with the forged pistons. also need soem suggestions on what heads to run..leaning towards a set of darts. this setup will be a track mostly car and an OCCASional weeekend of cruising the local strip. another question is about the nitrous setup. i guess you would just use a conventioal plate system under the throttle body as you would a carb setup? or i guess you could always go direct port..i am really hung up on the stealth ram though..i love the looks of it..i just wonder if i can direct port it for n20 or not..was originally going to go with a procharger but the cost is so much..i cant justify not juicing in instead..any and all comments are welcomed.
thanks matt

I bought two Accel DFI units along with the wideband O2's. Well just after I received them Accel they did an upgrade from there 3.2ver to the 4.0ver. Well after just forking out over four grand for there stuff I thougt I could get them to upgade my ECMs. Those greedy F___ers wanted to charge me $180.00 a piece. Well, these are the last I buy from accel. There are two many others out there to have to put up with this crappy customer service. You may also want to look at the Fast system or the latest Big Stuff units. I hear alot of good things on those.
As for as the manifold, I'm running a super victor converted for EFI. You have two ways to run the throttle body. A conventional 4V type are the cool 90deg. sheetmetal ones. The holly stealth may give you a bit more low end tourque though.

i dont really care about the low end torque all that much..its just the holley had the manifold and stuff already prefabbed so i wouldnt have to modify a sbc unit for the fuel injection..i dont know..probably wont fit anyway, just thought it looked like a promising system..i just dont know how much "tuning" you can do with their software or if they really support the power they claim to..you can get the systems all the way up to like 750 horse..
In my opinion, I'd use the DFI Gen. 7 system. There is a Company in Florida, Force Fuel Injection that converts intakes for EFI. His web-site is http://www.force-efi.com ask for Rob.
I can understand the pain you feel about the $180 for the update, been there done that. But I can say it's worth it. After we got ours back it had quite a few extra tables that I was able to work with and it enabled me to remove the manifold surface temp sensor, which looked nasty on top of the intake.

Wilson Manifolds also converts manifolds to EFI, and they have some killer looking fuel rails, if you like purple anyway. i'm sending my rails out to have them speced and a new set of theirs sent back just for that reason. plus mine were a bit ugly looking too.
later,

oh yea.......another vote for the Accel DFI Gen 7.
so you guys have had good luck with the accel dfi setups? i plan on building a high compression forged sbc motor..all the normal good stuff, prob some afr heads or darts..good solid forged pistons,crank etc..then going to spray a 200 shot on top of it..i want to go with a stand alone injection..ive weighed the cost of swapping a ls1 into it or putting another lt1 back in it..the prob is that i dont have the accessories or anything for either motor..i can build a sbc with a stand alone system for less than i can get any of the other two..i would like to have about 550 horse on the spray.. i thought real hard about getting a lt1..but then i thought of having to buy a whole pullout then buy new heads..port the intake injectors etc....hell the sbc will be cheaper i would think....

I realize this thread is a bit old now but it's still on topic. If you look at teh new Hot Rod (may 2005) they have a good article on page 84 all about the new EFI systems that are out on the market maybe you should try and check that out.

If you're not an EFI expert I'd look into the F.A.S.T. system. I've done a bunch of them when I had my shop, it's by far the easiest system to install. They don't have as many tables to work with, but the one we installed in our 66 Mustang last year worked flawless and got 21 MPG on Power Tour last year. The DFI has more tables and if you know the system really good you can get more out of it, but for a beginner I'd suggest the FAST.

look no further than the Ron's Flying Toilet - This thing is bad, 1200-1400 cfm may sound like a lot but its not. I think Its comparable to a 750 or 850 cfm carb. This is a standalone unit with no wiring(mechanical fuel injection). Very simple to tune, all you have to do is change the "pills". Comes with belt driven fuel pump. The kit is only 1400. Thats not bad for a fuel injection system that includes the fuel pump. This system is supposed to be real consistant. www.killerrons.com

Has anyone run this system so far? How is it tuned?

I havent ran the toilet before but I know a guy who has and he had good luck with it(8 sec range w/a sbc and a mini blower in an s-10). I have also seen it on a lot of bracket cars. I am getting ready to buy one. I read about how to tune it somewhere but i cant remember where. From what it said it was very easy to tune, you just change out jets or "pills". Also try www.ronsfuel.com

Ron's on a street car would be a mistake. Even though you said it would only be a occasional street car you don't want to do a toilet on a street car. IF it were a track only car then it would be great, but not even for an occasional street car.
