Engine swap 2.0...2.1

To swap from a 2.0 to a 2.1 in an 88 SI are there changes needed.
Different ECU...Intake...transmission???

Better idea would be to drop in a B20A. the B21A1 that you want to drop in tends to have problems burning oil, because of an experimental material used for the cylender sleeves.

Check out www.preludepower.com you can probably get more questions answered faster and more completely then you can here.

lol I thought I was the only one refering people to www.preludepower.com ! lol, good advice man. Yeah, drop in a jdm b20a like he said, much better choice.

The JDM B21A had the same piston sleeve material that the B20A had. you are correct about the USDM though. I would take the JDM B21A3 because it has a higher comp ratio, 165hp, and 137 lbs of Tq. yes the stock tranny will work, no you will have to find a USDM ECU, and Intake manifold. I highly recoment a clutchmaster stage 1 or higher clutch with this swap.

Your V-8 can't touch this sweet Honda Integra XSi....
