At my local speed shop, one of the techs told me that he had a customer that had at least 3 J-spec engines, he thought they were 13b. He didnt have the guys number but he told me he would get the info and call me when he saw the guy. He told me that he would want around 3 to 4 hundred per engine, what should I look for? I was told that some of the J-specs wont mount up in place of the original and fabin my own stuff would be a bitch. When I get the info and someone is interested, I will post it. Mine is a 88 n/a SE. Forgive my name, wishful thinking.



Thanks

3-400 is a good deal, but becareful, word is they are only good for rebuilds, unless you get lucky. If they are 13b they will all mount up fine.

I considered buying a j-spec one but ended up just rebuilding. I figured if I kept the car for more than a few more weeks i'ld be happier if I did.
