Sounds like a good combo, those shorty headers are not going to do much for you.

If you mostly race from a roll I'd go with a tight converter like the PI2800. But if you race at the track mostly I'd do a PI3200.

Your original cam choice is fine, you might need to drill out the TB air hole to help the idle once you do the converter and the cam.

 

thanks but how cud i drill out the TB air hole ?

Find out what size hole other are using, then put a metal cutting bit on a drill motor or drill press and drill the stock hole out to the new size. Blow out the TB real good with compressed air, then put it back on the engine. Did that answer your question?

the tb is 80mm shold i drill out the hole.?

and f u have any pics? pleas.

 

Since the hole is only active when the butterfly is closed, it won't matter what size TB you have. The blade or butterfly valve of your TB has a small hole in it that lets some air go through to help the engine idle. That's the hole you're going to make slightly larger. Start with computer tuning; you may not need to enlarge the hole. 13/64" or around 0.200" is a typical drill size.

 

ohh thanks ill try the computer tuning.

but what well hapeen if i do the computer tuning with enlarge the hole???

 

I just installed THE new cam 216 / 220 .525 / .532 on a 114, hardened pushrods and 918 springs. I also have all bolt ons. Wondering what I should set my rev limiter at I really don't want to over rev my engine. Also where would you expect best shift points to be.

This is a small cam though so I think you could get by with just doing one or the other if you had to.

I doubt it will produce additional HP above that, but you could check with the cam manufacture to be sure. I don't know anything about shift points; I'm a 6-speed guy . . . <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
