Since you're on a IX you can add a bit of MIVEC advance at idle to get some more lope. I'm running 6° MIVEC at idle on Cosworth M2's, idling at 900. 12 degrees timing at idle. I get just a slight lope; just enough to tell the car has cams, not enough to shake apart the whole interior

i've tried that before and it seemed to cause slight idle issues. i can hear the lope but its nothing like an 8 would have.


heres a clip of my buddies evo 8 that i have been working on with HKS 272s and a muffler delete pipe.

Kinda surprised no one brought up the FP4/5Rs those have the best sounding lope ive ever heard on an 8.
The sucky thing about cam lope is the driveability of the car will suffer, around town at those low RPMs is sometimes very unpleasant.

I actually plan to remove a bit of my choppy idle. Not a fan of the crappy initial start off/parkin lot maneuvers that result from "that cool sound"

Yeah, unstable idle results in unreliable take-off's. It generally requires a quick blip of the gas before starting from a stop. If you take off during one of the lower RPM lopes, it may want to stall and make you look like a silly noob.

Lol, 90% of the evo's I've driven are rocking' an Exedy Twin. I honestly think an Exedy twin is far easier to drive than a heavy 2600lb single disc.
