OK, Here's my question. I purchased a 90 Integra with a spun rod bearing. I used that car as a doner car for my swap in my 89 Si CRX. I bought a 92 B18a1 to replace the bad engine. Now from what I understanding, The 90-91 B18a1's only had a 130hp and the 92-93 had 140hp. I'm running a 92 b18a1 with a 90 teg ecu. Is that other 10hp in the engine or is it in the ecu, or is it a combination of both that make's that 140hp?

 

I'd think it'd be in the compression/cams

 

The 90-91 had a horrible stock exh. manifold.
The cams probably also changed along with the intake manifold.

I put a 90 ls motor together w/ the int/exh manifolds off of a 98 along with the cams and it ran pretty well.

I'd bet the computer had little to do with the extra 10hp.

 

doesnt a spun bearing usally mean the engine is gone? Just curious?

 

I think that's just a trip to the machine shop to get the crank reground and some oversized bearings.............

 

Nope.

And I wouldn't regrind a crankshaft EVER. Just find another crank in good condition and use that.

 

honda cranks have some kinda coating, you can regrind them, but only so much
thats what my dad said anywho

 

Keith thats not your hatch in your sig is it? Cause if it is man you must of had some kinda secret stash. Thats pretty nice.
