Protege MP3 all motor mods

[Spiced MSP]

just looked them up, not a bad deal at all. What specs did you go with? Stage 1,2, or 3 specs? Are they installed?

Stage 3. They will be installed in 2 weeks.

I sent my stock cams with the Intergral specs to Schneider Racing Cams to regrind. Got them back in about a month and they were under $500.

That is a good deal. But I'm confused about this. How do you regrind already smaller lobes to make them larger.

 

[cphillips23]

Lift and duration are increased by grinding away the "base circle" of the cam. The lobe doesn't have material added to it, but the non-lobe part is ground away making the difference between highest part of the lobe and the lowest part of the base circle a greater distance. If you grind away enough of the base circle, you can flatten the top of the lobe and still increase the lift while changing the duration profile substantially. That is the quick explanation

Stage 3 will be a bit too wild IMO

My car is not driven on the street, only the track. So not an issue for me.

what would you recommend for a DD? Is stage 3 cams that bad? They seem ok to me:

I can picture that. But how do the caps fit afterwards.

Spiced they'd be fine really jut that you'd have a really narrow power band. Do you have an aftermarket ecu?

Stage 2s would be better for a car that's a dd IMO.

 

[Spiced MSP]

yeah, Haltech Sprint 500. Had it installed not too long ago working on the idle and pretty much have it dialed in. But I took it back out until I get a few more things.

Id still go stage 2 or *maybe* max 2.5.

Otherwise your car just ends up really peaky.
