I know this is the LSJ section but I can't get a strait answer out of anyone in the LNF section, but does anyone know if the LNF tb and the LSJ tb are the same?

BTW, you won't see a gain like we do on a turbo car. Your charge piping will act differently that a blower sucking air in.

I dunno, hard to deny dyno proof. I think they have problems with customer service and actually going 100% complete on a custom project. But dynoing stuff is easy.

true statement. I already told you I'm going to be doing my own dyno testing. I'm also going to have both throttle bodies to swap out and test at the track at the beginning of next season.

Well, it will benefit due to having a bigger whole to cram **** in, how much I don't know. My main wonder is if they are the same size or one is bigger than the other. We had pretty decent gains when upgrading TB's on the older turbo dodges. Well worth the money.

No traction what so ever. The stock wheels and tires where so small that they would break loose on the high way in 5th gear. In the 1/4 it would run 13.2. Just a fun car all the way around.

Maybe, I think the car has had a popped motor for a few years now.
We did allot of them aswell from omni's to daytona's. They are just so damn cheap to build. Including the car and mods it cost 3 grand. The internals were all stock and we had a T3/T4 turbo with upgraded piping and blow-off valve and multiple in house suspension mods. When the last motor popped he talked about building/stoking/boring a new one but nothing has come of it as far as I know(I moved away after college). I haven't talked to him in about 3 years. I need to see if I could get a hold of him and see whats up.

Does the LS4 tb cause a CEL to come on if you're not tuned for it? where do you find them? lastly, Do they just bolt right up?

You CAN run the LS4 TB without tuning, but the car will run like complete and total ****. It will idle at about 2200RPMs and will be soo weird and touchy that it is hard to drive. Also it will try and stall. I drove mine for about 2 days before I was able to get tuned. Soo in essense it can be driven with it on, but it DOES NEED a tune.
And NO it does not just "bolt up". The TB blade is much bigger and will not clear the blower inlet causing it hang up and not open. You either need to port the hell out of the inlet of the blower to clearance it, or buy a TB spacer that will clear the TB blade. The spacer will likely need to be clearanced to fit also. The best and cheapest thing to do it just to port the blower inlet, because if you don't, your newly made higher airflow will just get greatly restricted again as it hits the small SC opening... The LS4 TB will however bolt right up to the TVS, if you are soo fortunate to have one...
