I've got a couple thousand to play with, and need help making up my mind...

- different cam (2nd gear too sluggish at low RPM's) ($400?)
- Ported Fast90 intake & throttle body ($1500)
- new QTP/Kooks/ARH headers ($800) & y-pipe (mine are cracked inside the collector and at the cat)
- custom valved shocks to match my 650/300 springs (DA's right now)
- brake upgrade
- adjustable rear sway bar setup
- fix A/C (been dead for years)
- suggestions are welcome


I've made up my mind on new headers, because I can't get accurate wbo2 readings with the leaks in both banks. Even though it adds cost, cats will be on it to keep the noise and odor at an acceptable level.

I'm not sure how critical the custom valved shocks are. I also haven't found an easy way to obtain custom valving while maintaining the stock mounting style.

It's cheaper to buy the cam now and wait on the intake & TB, but if I change heads later then I'll probably need to change the cam again. Buying the intake/tb now won't affect my later decision, but costs more now. I don't particularly want to spend the labor on installing new heads now.

I doubt the new headers will give me much more than the headers I already have unless the merge collectors are worth something. So you're saying to I need to switch from 3.73's to 4.10's? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)

Headers (with merge collectors) and shocks are what I'd do in your situation. Headers to fix the leak, and the shocks to put more distance between you and your competition...(IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

If you still have the OE rearend housing, I'd stay away from the 4.10s. gear teeth are too thin to handle the load compared to 3.73s or 3.42s. If you upgrade to a 12-bolt or 9", you'll be adding weight.
