i am planning to buy and rebuild a motor for my 95 4dr teg LS. i am a bit of a purest when it comes to things and a tad bit too ****. i know a b18b would be the easiest because i can drop it right in and go. but i want more tourqe, for auto-x. so i was thinking b20. if i go with a b20 what do i need to know. is it a direct drop-in or will i have to modify things? most of the ones i have found are ODB2 as well but considerably cheaper. any help would be nice, and thanks in advance.

 

if you decide to go b20, you can use your ls wiring harness and it'll plug right in. the b20 does have a nice flat torque line. but if you plan on building it, do not skip sleeving the block. b20 has weak cylinder walls.
