GT2871 USERS. SR motor

[slider2828]

Any more, I'm becomming less and less a believer in the stock manifold providing world changing low end response. Sure it's there, but it's only a 2-300 rpm of spool, and maybe 5-10 ft lbs down low. To me, that is not worth giving up the 20-25 peak HP up to, and the elongated torque band. In the end it's not worth nitpicking over, as the average power increase of the greddy manifold is worthwhile to me.

I fully agree with cody on this one after getting my setup tuned on a stock.... I found that I rather go with greddy or truthfully ISIS.

1. Unless you are trying to initiate drifting at like 3500 rpm and probably still not have enough torque to do so on that GT2871R to drift, your not going to miss that spool up time

2. It cleans up EVERYTHING under the intake manifold. Oil filter, water lines, knock sensor, oil relocation/oil cooler lines have WAY more room. You can get to it from under the car!

3. You lost a LOT of top end. I mean after about 6000 RPM, your torque and HP drops like a rock.....

This is what I found....
