for the record:
ditch the h23a1, it really doesnt make enough power (NA), even with all the bolt ons, my engine stock would destroy you.
turbo is the only thing an h23a1 is good for.
i know this because i raced a 96 prelude Si (it had dual exhaust coincidentally) with a sh*t load of bolt ons, and a nice big tach.
this is a few days after i finished breaking my fresh engine in.
he went on 2 instead of 3 and got a car length head start but that didnt matter, because i was still in 2nd gear at 65 mph while his h23 was trudging well into 3rd. i couldnt even see him anymore on the highway by the time i topped out 3rd at 90.
then my bro beat his ass after me with his 93 talon tsi.
then i beat my bros ass.
also
i raced a 1995 GSX with my h23a1 injectors on my h22a1 and was dead even at about 80-90.
i had the wrong injectors in when i raced the 96 lude too, but that didnt even matter.
now that i have the right injectors (345cc) no honda (besides the s2000) is safe from me. :fawk:
i take 5th gen ludes too no problem

the turbo eclipses definitely have more potential "from the factory" because it already has a turbo on it. but i agree with the earlier comment that a turbo prelude can easily compete with a super boosted eclipse.
dont forget that honda makes 197 horsepower from a 2.2 liter NA engine in 1992, that fact alone is very impressive. the fact is NO mitsubishi 4 cylinder NA engine will ever come close to the power honda has with DOHC VTEC engines. not too mention that engine life decreases severely when you start playing with boost levels
boost is for wussies
