I agree, sell the non turbo and buy a GTT !!
They are starting to sell for reasonable prices. I picked up a 2001 R34 GTT, silver with only 28,000k's, HKS cat back exhaust, Tein Type Flex Coilover Suspension with EDFC, Apexi Turbo Timer and a few other goodies for under $30 k about 4-5 months ago.
Good luck.
