I just decided to supercharge is down the line. Alot less work and really about the same amount of money if not less
dont want power much below that. I like my 35 mpg and i've already got a z6 head so I'll have the advantages of a somewhat higher redline. and with some pulley work I should be able to get the power to kick in about at 4500-5k RPM.On a d series? Good luck with getting power under 5-6,000 rpm
