this could seem like a stupid question, but i just decided to ask cuz i was pondering. well the question is, why don't they use integra type R engines instead of h22a. i heard the type R is a better engine. also it put out the same HP right?? and well it a better engine to turbo. would it be better the use a Type R engine, then to swap for a h22,h23, or h22a(version)? i mean i have a lude and i love it, except for the SS thing. Well thanks for your time. most prelude owner should be really mad at me now, but i just wanted to know.

 

It depends what you want to use the car for... remember to have a goal when building. H22s have better torque at a lower rpm. B18C5s have closer gear ratios etc etc...autocross/road racing/drag/street...

 

i dont think a b18c5 (jdm b18c) would perform as well with the prelude weight. the h22 has much more torque

 

H22's have much more torque than a B18C5, and handle boost better. They also bolt right up in the lude! Whoa!

 

As others said, it's one factor: torque.

I have them both, just not in the same car...

 

That is not true.
