We performed a great deal of work on a Nismo as Dai sated. The car laid down 598rwhp before running out of fuel. For cooling it had a Z1 34row oil cooler, CSF radiator and a vented hood.
Last week we also tuned a GTM Stage II TT Nismo that laid down 544rwhp. And as far as the driving experience the GTM kit pretty much blows the 20G out of the water. The Greddy feels really lazy kind of reminds me of driving a Z32 with larger turbos. Laggy but when they kick in they really kick in. The GTM kit pretty much is a rocket every time you shift gears.
Hope this helps you in some kind of way
