I have a h22a prelude and I was at first planning on going turbo, so I got some dsm 450's....then i decided to ditch the turbo project for all motor, I am positive the 450's are way too much fuel for all motor, but what is the suggested fuel injectors for going all motor...im planning on upgrading the whole engine soon(high compression bottom end and built head including camshafts)..i have a fpr and a afc for fuel management also just to throw into the equation....

 

You could still use the 450s. I'm running 39#(410cc) injectors all motor. I'm using Hondata though. You'll have to take out quite a bit of fuel, but I think you can get them to work.

 

Im running dsm 390cc's from an auto TSI with a chipped ecu from Cheetah.The car runs a little rich but thats how I wanted it.
