The stage 2 block is just an upgrade over stock internals. In my case, the SBR (
www.slowboyracing.com) stage 2 block has eagle rods, and ross pistons. It varies from vendor to vendor. I went with a built block because I plan to make up to 600 whp in the car eventually.
Tuning means that you are using some type of feedback device (datalogger), and something to tune your airfuel ratio (and perhaps timing). This can be an EMS, but very few DSMers go to standalones with the other options that are available. It could be as simple as an Apexi SAFC (250 bucks) to control fuel and a pocketlogger (
www.pocketlogger.com) to datalog, so you know what changes to make. Some 90-94 guys swear by HKSs now discontinued VPC instead of, or inaddition to, the AFC. Also check out
www.tmo.com. Most poeple with 95-99 cars prefer the DSmlink, at
www.dsmlink.com, which combines everything you need into one package, but still isnt a standalone EMS. Poeple are running into the 7s with these simple options and stock computers.
