My top chum imports Skyline GTR's into Christchurch, NZ. He races one. He gave me the use of a "Fairly soft" 380hp thing, when we were out there. Holy cow! It frightened the crappers out of me. Snick it into 2nd off the line, floor it and all hell broke loose. The revs went mad, all four wheels were spinning and the steering wheel was having fits! The one he races is 850hp using a standard block. Put Christchurch GTR into a search engine and checkout 'Pommy John' if your interested.
