SR20 B12,
I'm curious to know why was it more difficult to put the CA18 in a B12 than an SR20. The Pulsar is built on the same platform as the sentra which equalled a straight bolt-up ( no cutting, drilling, etc). You say the SR20's bottom end is more stout than the CA18's? That statement my friend is very argumentative and many nissan gurus will argue that as well. I've seen your uncle's engine opened up because of some trashed pistons. The SR's block is alloy whereas the CA18 has an all iron block. I'm gonna put some pics of my girlfriend's set up as my own B12 is in surgery (major reconstruction). My friend has an SR20DET in his 200sx and surprisingly it hasn't blown up since installation in Feb. 2000. He has ran a best 13.9@103mph on street tires, but has gone through 3 trannies already in which I just recently put one in on 6/8/02. But whatever anyone choose to put in their vehicle, they should do some serious background searching because different folks desire differents strokes. The SR can kick some butt on the street and strip. And the CA can kick some butt on the track and has proven to be one mean and nasty 1.8 on the top end (My victims will atest to this). My friend with his 200sx are almost equally powered when racing my friend with the S2000 and whom both are pretty good street racers. But the S2000 walks away at 135mph. At 155mph the s2000 is about somewhere about 6-8 car lengths behind my B12, but that's about as close as he get before I step on it a bit more. Long gears+power= Goodbye...........
