Havent you put alot of money into that car? What will come of it?
If I were you Id stay away from VR-4s. As many know, Ive been building DSM engines for about 8 years. The VR-4 has some balls, but the weight is such a huge issue. Ive raced various highly modified VR-4s in my Z and had no problem beating them while I was in close to a stock trim. Stick with a Z man....Perhaps a new 350? =)
