I was doing some thinking I was wondering if it would be worth it to get a b20 block for my ls integra. What would I expect power wise, and what needs to be done for this to work??

 

you need a different head as well....a vtec head. b16 would be good...I dont think it would be worth it to put the b20 block w/ b18b head.

 

the B20 already comes with a B18B head. it uses the same head as the intagra LS.

 

I know that I should get a vtec head, that would be much better, but I'm just curious if the added displacement would help me out.

 

I think that if your engine has alot of miles on it and you are about to plunk down the cash to replace the timing belt, water pump, etc. you should definetly consider paying a little extra and get a newer b20 block because it will definetaly help your performance.
