what engine can i put in a 90 prelude?

 

swap whatever you want into that car. you can do the h22a swap. there is a mount kit for it. it all depends on what you want to do with that car and how much you want to spend on a motor swap.

 

The easist and probably the most trouble free swap if you have the B21A1 is a B20A. My B21A1 has 240,000 miles on it and showing it. I am planning this swap next year. Pretty much everything is a bolt-on, even the tranny

 

that would be swapping in a lesser motor. unless you mean the jdm b20a motor. that has more power than the usdm b21a.

 

i can get anything you want out of a 90 si b21, including the engine and tranny, let me know if you want it

 

of course I meant a jdm b20a... but even going to a us b20a would be an improvement in overall quality of engine design from the b21a1. From that solid foundation you could build it up to kicka$$ specs
