yeah I had pix of the porting cause I was gonna post them in the external section but I thought the porting did not look that good so i did not post them,I deleted the pix on the camera.I think it gave me around 30rwhp from the manifold & tb swap
next plan is to put qtp or american racing headers.my slp's have popped twice in the last couple of months where the collector meets the y pipe cause the car is lowered and the exhuast hangs to low.that should be arond 10hp there also.
