240 ls1 t56 build thread
My goal is to make a nice street car with 4-500rwhp, and not go broke doing so. I am a dealership technician, this will be the first time I swap a car to a non stock motor(although I change motors and trans regularly), and have minor fabricating capabilities(110 mig). Im really looking for advice on how to go about this without making mistakes other have already been through. Right now I am thinking of getting a gto ls2 and trans and the swap kit from hinson or sikky. But I really have no idea if that is the best route or if there is better/more cost effective way.
edit: I forgot to mention I want power steering and ac, Im not worried about cruise. Also was wondering if dbw or cable is the better way to go?
Thanks for any help, I will continue searching and reading all the threads and forums I can.

If you go with cable, make sure the PCM will work with it. There are certain PCM that have a chip in them that allows you to switch to cable. I'll see if i can find the post, there is one floating around here somewhere.
If you go with a truck motor, you'll need to switch the accessories to f-body or corvette setup. Depending where you get them from, this makes a truck swap comparable in price to LS1 swap. There is a guy on silviav8 that fabbed up his own also.
I am thinking of going with the Moroso pan, either from them or Fueled Racing. It's like $600 with filter relocation and dipstick.
If you can weld you may be able to save some money and fab up your mounts. I am also going to try to fab up my own headers. JEGS and Summit have kits for like $250-$300 that has a flange and a bunch of tubes.
Also keep an eye out on car-part, i have found some good deals through that site as well.

I am still undecided on what I want for mounts but I am leaning towards going with sikky for mounts, oil pan, and headers. Anybody have any bad experiences with sikky?

Im going to do all the harness work myself. As for the diff I plan on starting out stock(open 4.08) but will change later once I find parts. I actually have a lead right now on a early 90s q45 diff. If I can get that I may be able to get the vlsd and 3.54 gears out of it and installed in my stock carrier.
