I was in the pick n pull today and I found a late 80s early 90s prelude (the style before the last one) with an engine that had what appeared to be an LS head with a block stamped B20A5. I thought Holy **** is this a B20 motor with an LS head? SO my question is: IS IT?!? I can get the whole thing for like $150 is this a B20 or did the lude come with a similar engine? Thanks

 

don't buy it.

 

i wouldnt buy it

 

that generation of prelude came with b20's..

 

but they have very little in common w/the b-series your thinking of. this b20 got its size from stroke, not bore, giving a horrible r/s ratio

 

What they said. I really like 3rd gens but the motors are bloody freakin' average.

 

And??

The B18C5 has a " bad " R/S ratio, and it revs nicely to 8000. In fact, the H22A with its " less then ideal " R/S ratio can also rev pretty high...

R/S isn't the final say in what makes a good engine from a bad engine...Hell, someone provide me with valid, scientific evidence that 1.75 is the " ideal " R/S ratio.
