Hello,
I am getting a motor built, a 2.9L m20. I believe that is the 84x85mm crank / bore with the standard 2.5i head. The head has a decent port and polish, +1mm intake valve, it will have long tube exhaust header and custom exhaust, with dbilas ITBs.
Question about the cam: will this thing be suitable as a daily driver? As in, will it idle, will it have a smooth power band, will it pass emissions (with a temporary cat installed)? I will have an MSPNP and a proper tune.
Thoughts, comments, suggestions?
Cam specs:
296 inlet
296 exhaust
258 inlet / exhaust
106 lobe center
12mm lift
3.6mm lift at tdc
42/74 - 74/42 IO/IC - EO/EC
2mm clearance to
122kp valve spring hardness
37mm fitted length
I think it is very similar to this cam, except with slightly less lift:
EDIT: I had the wrong link. This is the correct link to the 296 Dbilas cam:
Thanks!
