what are the trick mods for performance power when building a D-jet motor . it is a tired 2 liter that will be getting a big bore 2056 piston kit.

what are recommendations for valves, porting compresion , etc....

will be a driver car 91 octane gas, , have SS heater exchanger, and I do want heat.

There is a shop in the Venice Beach area, I think, named "NARW" and the owner raced a 2L type four in vintage events for a few years and it made about 120 to 130 HP and had a "stock looking" throttle body, FI brain, injectors, etc. I think the brain was done over by a shop in northern L.A. and used heavier injectors and the throttle body was honed a bit as the engine would easily rev to 7K RPM which is difficult to do if the FI system is stock. I used to have the contact info but it all went with my car when I sold it but that could be a place to start. But as some have said, anything will NOT be cheap!

Unlikely stock D-Jet trigger points for the injectors would stay accurate at 7k rpm's.

could yo not bend the trigger points spring (or shim it) to increase tension to prevent bounce? (of course the wear blocks would wear faster)
