This is a build we did for one of our GTRC members this winter.
It took alot longer than it was supposed to but over all we were very happy.
We had a Customers GTR show up on a hook a while back complaining of a loud knock in the engine.
He told us a story of a spirited drive in the mountains and a nice revmatched downshift on his way home and than this.
bought the car and drove it for a total of 3 weeks before the build.
History on the car.

Fire it up and sure enough, spun rod bearing.
So out it comes and we tear it down.
Pictures will explain it better.

I've heard the OEM O2 housings are pretty restrictive too. Add a nice set of HKS ones and breathing will be even better.
