well my ls motor has too many mile and I am getting a good deal on a b20 long block and I was wondering if I can swap all the ls parts on the b20 and run perfectly?

 

yeah u can transfer everything over, but running perfect - well good luck Get it fine tuned and it will run perfect. The one thing is the wierd canister thing on the back of the B18 (which I think is for emissions) will not be present on the b20. Well it wasent on mine (JDM b20) so I just plugged the line off of the Intake mani that would lead to it with a screw and some red silicon. Hope that helps.

 

thanks!!!

 

Everything can be swapped over, and it will run perfect. Just run the pcv line from the top of the valve cover to the input on the intake mani (where it would normally goto the seperator on the back of the B18 block).
