the last D series NA motor that came through here that made over 190whp, blew up 20 dynos later. Impressive motor, but they are PURPOSE BUILT RACE MOTORS, they do NOT last.

150-160whp D series is a STRONG NA motor with TONS of work and money in it, and it wont go 12s.

you could just buy a GSR an have the same power out of a STOCK MOTOR an it would probably cost WAY less.

Or

Turbo the D series an pwn everyone.

NA d series is cool for a race car. Call BIsi, i suspect his motors run $10,000-15,000

there is a reason why everyone runs DOHC
