you could do a g23 all motor. does anyone remember that? IT had an article awhile back about the g23 motor this guy built. i dont remember his name. i kno i got the issue somewhere tho. all the motor is is a f23a short block and a h22a head using k20 pistons and a b series transmission with i think it was earlier integra axles. i kno there was alot of different parts from all the motors mixed in there too i just dont remember. but it was supposed to be cheaper than any of the other motors with a higher out put in power in stock (not aftermarket) form. id love to see someone do it big with that motor
