From what I hear, it's HP......gotta have it.
The chassis is great out of the box, improvements can be made but are marginal. As for HP, there's one name: John Milledge Engineering. He's local to you. Thats the good news. The downside is, for various reasons, the technology involved in chasing 944 power is pricey. Less cyliders than an E36, but more dollars than a Sunbelt E36.
Break out the piggybank, AND the IRAs!
Kip Van Steenberg, and Chris Cameadell are two NE guys with spotless cars. Top notch spare no expenses deals. I will be badgering them for info when I decide to do mine, thats for sure.
Milledge has a book, like Jim Suskos RX-7 set up manual for 944s for $100.....
