I found it is usually cheaper to find a kit that has most of what you are looking for then add bits as necessary. Not sure exactly what kits work on a crossfire, but a quick google should get some hits. You should be able to find some kits without bottles if you don't need/want to have two.

you'd have to use some seriously small jets on that, and it looks pretty easy to build.

That's the setup that I'm going to re-create on my engine as well. Got all the parts to do it, just lack the guts to bolt it on........

Why?

It's not like you're bolting on a 400hp plate system or something. Just keep the jets small, and if you have any questiosn, talk to NOS, Edelbrock, or whoever you're using the most parts from. They'll help you to make sure everything is set up correctly.

Like any major mod, be careful and watch things closely till you get used to it and know it works correctly.

I'm just a whimp and don't want to grenade the engine. I've got jets for 70hp and 100hp so it'll be tame. I just want to get my EBL computer setup first as I'm just running a stock ECM with an ADL "off-road" chip in it now. I'm sure my tune is pretty far off.

My setup was stolen over the summer. I had everything needed to do the nitrous. but now i am kind of glad they did because my engine is slowly starting to wear away. i guess it just wasnt meant to be. but this winter im going to rebuild it and maybe have a base hp of 450 so i will not need nitrous. also changing the intake to projection FI.

Well, that sucks. I'm interested in what you have planned for the new engine though. Have you seen the Renegade intake yet?

Did you get your car running with the renegade yet? Have you did the post dyno run yet?

I had a problem and had to leave it parked last weekend. I'm headed up there now to see if I can sort it out. The Renegade was fine, the problem was with the valve lash - possibly that the cam is going flat.

That production kit is no longer available for CFI, but you may still be able to buy the parts or cobble something together and make it work. If I remember right, there was a guy that was featured in one of the vette mags a number of years ago that ran the CFI kit in his 84 and ran like 11.4s or somethng like that with it. I just don't remember all the details anymore, but you may be able to Google it. Good luck and don't let it go lean.
