8:1 should be perfect for that range. It just means you can run more boost without knocking. :) > >The setup you describe gives about a 8:1 compression ratio.

Any ideas on injector sizing? > check this out: http://www.smokemup.com/utilities/calc/fuel_injector.cfm for a 300hp turbo'd 4cyl, it says you would need 41lb/hr injectors. You'll also want to pay attention to where you end up putting your injectors... I would try to stay as close to the stock locations as possible. You might want to just make a new top piece of a manifold and use the lower half, as long as the fuel rail would fit ok. > >The SDS EM-3 is probably the least expensive easiest to use programmable > >system out there for the setup you describe. > > The SDS system complete should run around $1000, right? > Sounds about right to me, with the sensors you'll need, etc. > >Oh and you have to clearance the piston tops to clear the 16v valves.

A custom set of pistons won't set you back that much, and you'll want forged ones for high boost levels anyways. Using the ABA block would help you drop compression, but it would porbably be cheaper in the end to start with a 9a. _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
