I have a '90 Civic Si manual with a lopey engine. It rumbles, or rather struggles to get up to speed. I'm thinking in case I can't find a solution to fix this motor then I'll just swap in a spare motor. Let me know what you guys have laying around. Thanks.

 

look up foreign engines in lynnwood.

 

I've been there twice many years ago and was just looking for that place but could think of the name.. Thanks function83

 

I called them, they want something like $695 for direct replacement. I'm not paying that. I just learned of a guy in the Portland area who is pulling his really smooth d16a6 in about a month. I'll buy his motor so he can buy his B series. At $250 for the motor/tranny/ecu I'll take that option.
