So...Convince me on a cam.

[01Blackgtp]

I have done everything, I mean EVERYTHING possible to this car except cam, and bottom end.


Paint, interior, exterior, wheels, suspension, brakes, headers, e85, intake, rockers, intercooler, 2.8, e-85, plugs, wires, hp tune, stereo, dynamat, carpet, floor, seats, alarm, tint, full exhaust, gauges, TEP trans, 3.29s, fuel pump....whatever....Its pretty much been done. Or its been taken apart and re-assembled.

Here is my dilemma.... I am at 303 fwhp, stock cam, stock bottom end. I want more.

I am thinking the next step is full phenolic IC, Northstar tb, cam, swapping out rockers from a 1.9 standard, to a 1.8ish yella terra roller rocker, with springs, dual timing chain, custom grind cam, ect...


My concern is emissions, I am in an area that runs a sniffer test on the dyno. and I already have to run a special lean tune I put in to pass then every 2 years.

My question is, how impossible is it to make a cam pass emissions?
If I go for broke, do the cam, head work, tb, ect. am I screwed when it comes to emissions time? I fully understand that pulling that blower off and going turbo will make more power. but I am really looking for that 350, 375 fwhp blown mark.

We don't have emissions here, so I don't have any experience as far as passing goes. However, using the car's systems to test emissions, I can tell that you will have a difficult time passing with anything other than a vs cam. All the other cams misfire too much at idle making it difficult for the o2 sensor to work properly.

You also may have a shot with the xpz, but I don't know for sure. You may be better off working on improving your intercooler.
