There's that lag I was talking about. Regardless I wouldn't mind it lagging a little bit. Makes for a better daily driver in my opinion lol.

A 4.3 is said to have a bottom end that is good for up to 350hp. As was mentioned by a couple people in here you will have to upgrade to a high flow spyder assy like the one from Al at Wynjammer or a marine intake. Personally I like the intake route for real injectors, more ports for temp. sensors etc, fuel rails, medium rise & a bit better air flow.

350 huh? I was expecting more, but that's still a good number. My Integra is putting down about 260whp and it's pretty zippy as is. I think the intake would be the best route to go.

Freeing up the exhaust will be a bonus by allowing the engine to exhale better as well as a cam for obvious reasons. You will not see any mpg gains, lol trust me.

I really hadn't planned to do much to the exhaust. I currently have a hollowed out catalytic converter and a stock exhaust system, I was thinking of either replacing the cat with a high flow, or just welding in a straight pipe. The stock muffler is probably going to be replaced as well. I don't want it too loud, but I do want it a little beefer sounding then stock lol. I didn't expect to get better MPG with a turbo. Honestly I kind of expected it to go down a little. I suppose the marine intake could help things flow a bit better though.

As for the PCM you can go to pcmforless.com, waitforme.com & others to get the pcm tuned for your application. I took mine to a local dyno shop & had them tune it on the fly on the dyno. (see my signature)

I'll look in to the websites you listed there. I'm not sure if I can track down any shops that will tune it. I've looked in the past and had no luck locally.

Oh I know how that goes. You learn and get some experience along the way. It's all worth it in the end i'm sure, haha.

Thanks again for all the replies! I have a lot of reading material I can look in to now. I really appreciate it. Any more comments/links are also appreciated.
