well i was about to buy a GSR swap for my CRX, but im deciding to go another route and i dont want to spend too much money on my car right now(and trying to keep it sleeper). ive decided to go D-series route...D15B vtec to be exact(the old D15B2 might find its way into a go kart or my lawnmower maybe ). here's what im thinking of doing so far: P29 or ZC pistons and new rings(.25 oversized) P28 ecu with uberdata gsxr1000 itb's(ive had them for awhile now) bisimoto header spark plugs :shrug: Does anyone know what the compression would be? i used a d-series calculator but its giving me like 14:1, is this right? im also trying to decide on the cam right now: JG engine dynamics or Crower stage-3. ive read that the stage-3s need head modifications; does anyone know what exactly needs to be done? also, which one has a better(flatest torque band that will go up to like 7500-8000rpms). last question; does anyone know the flow rate of the GSXR750 injectors? is it even possible to use the GSXR injectors? Thanks for the help.
