LsS13

hey guys my question is probably not very smart but I need to know i want to grab preferably the all aluminum l33 vortec aand swap to my s13 but just to make sure i need the complete engine harness (obdII included) and the factory pcm? Also when i get those I need to get the pcm reflashed? and lastly is the trans harness part of the engine harness? im new to swapping different makes i usually stay in the realms of the manufacturer lol any help would be apperciated!!!

For your first time, I would recommend getting a complete drop-out with engine, trans, wiring harness, ECU, and all accessories. Find a salvage yard that does this regularly, so they know what you need. Little things like exhaust flange and transmission yoke sometime get forgotten, and are hard to find later on.

Next...send your harness to one of the vendors on here, like BP Automotive, who will rewire your harness.

Last.....Plan on finding a local tuner who has experience with LS swaps. They do have their quirks, and sometimes need more time than a "canned" tune.

Good luck.

Maybe $300-400, depending on what you need done.

okay cause i got the lm7 and a t56 from an lt1 that im gonna convert over to use on an ls1 but the harness has the trans wire on it as well am i correct?

Not sure on that. I don't mess with wiring at all. It's too time consuming, in my opinion, to remember all of the variations.

Probably. I have never used them, but I know they are one of many mentioned on here. Most will remove VATS, if you have it. But you still need a local tuner to really get it right.
