200R4 update
Just because I haven't updated this in forever, I did have to rebuild the 200 4R after 7 years of abuse. the front pump was going and I was about two hard shifts from breaking a bunch of internals according to my friend who rebuilt it. I went with a PTC 3800 stall at that time and gained about .2 off my quarter mile times.
about a year ago I had a knocking in the motor. I pulled it and had it rebuilt. There was a vibration he believed was from the Fluid damper and my oil pick up broke in three places. There was a bunch of other stuff going on so I had it line bored and the cylinders cleaned up. All new bearings and rings, but reused the Diamond flat top pistons. Found 4 cracks in the Scat crank and replaced that. Went with a sloid lifter cam this time. I also went with nitrous this time. It got expensive, but it dyno'd at 530 hp naturally. The nitrous will add 125 more. It's going back in in a few weeks and I can't wait to drive it again and get it to the track.
