Minor turbo related update...
This weekend as I had the Redline R33GTR with me, I took a few comarison pics of the turbo for the Chaser next to the one on the R33.
The turbo on the GTR is a Blitz-KKK650 jobber and the powerband on the GTR is more than acceptable for me, even though its very roughly mapped at mo, and running a low comp engine with 280degree cams.
It has good power from 3.5k and mental power from 4.5k and with RB26s being very high revving engines, its a really big powerband.
Even with a massive exhaust manifold crack it had all weekend it still had a good enough powerband for me.
Hard to tell in pics really, but in reality the compressor is a little bigger on my turbo, but if anything the exhaust housing on mine is slightly smaller, and without the gay 280degree cams it should be just nice.
NEED to do it though. Even the GTR isnt fast enough to keep me entertained for long TBH. It takes a properly fast car to keep me amused.
