I've dumped thousands of dollars into my car in the suspension, rims, bodykit, etc. but I've spent little if nothing on the engine. I'd say if you want a cam gear--go for it, but be sure you get a good one and know why you would want a cam gear.

As for Nitrous, it seams like a real quarter mile tool and I'm not sure the Accord is a true qtr. mile threat. I'd be sure the tranny is up to it first manual or auto.

I've also had the pleasure of driving many turbo charged Accords, thanks to some very generous owners. And I'd say as awesome as the rush is, more often then not the setup is never done being tuned...and I'd rate even the best as 8 out of 10 for streetability. As for fun 4cyl. I'd still rate the H22 Lude as the best with the manual TSX in second. I wouldn't swap a 6th gen either I'd sell the car and purchase a used Lude my self.

If your Accord is used, and I'd say most of them around here are.....I'd really dump every penny I could first into fixing the parts that keep the car running. I'd replace all the belts, hoses, plugs, wires, etc. And not with speed parts just good old fashioned new stuff from Autozone or what ever. Then replace everything that needs fixed on the suspension, new bushings (if needed), if your shocks are junk buy new ones and they don't have to be ubber Koni's to improve the ride. Then instead of replacing the exhaust or intake, get the car cleaned up. Fix the carpet if needed, replace seat fabric or headliners if needed. And if you can't polish a car to new car detail pay someone to do it for you.

Clean up the ride first, make it mechanically sound, then and only then dump money into tuning it. If you can't start the car everyday and drive it to work, school, etc. faithfully you might as well own a POS or something.

Sorry for the long rant.
