LLT 3.6L swap in a gbody

[Clone TIE Pilot]

its a guy on ebay that rewire lsx harness and add a fuse box to the harness for 190.00 i figure that would solve the wire harness issue.the next challenge would be the motor as far as getting some custom made.along with the drive shaft.but im hoping that it wont be a hard thing to do being that the car came with a 3.8 carb turbo.

I dont want a 350 in there because the are just not as efficent as the new motors i would rather rebuild the turbo v6 thats in there if i was going to go that route.not to mention if that heavy camaro gets 30 mpg to the gallon then i can only image what a 80 monte would get being that its a lot lighter than the camaro.

If you are really looking to go that route you would almost have to find a wrecked camero and get everything out of it b/c there is A LOT of electronics behind that engine between the high pressure fuel pump, coil on plug, and the cam phasers, besides the throttle by wire.

It would be easier, and probably cheaper just to get a E-rod LS3 crate motor, there really isn't much sense to put that much effort into swapping in a base motor V6 that would cost just as much as a V8. BTW, Gen 1 SBCs can get good MPGs if built right, most people just built them as cheap as for as much power as they can, not for best MPGs. Good heads like Vortecs, good CR, and proper quench, and at least a Qjet if not some form of EFI with a overdrive trans and you can get mid 20s easy. Most people just slap a gas dumping aftermarket carb on a a SBC built with a poor combo of parts and a non OD trans.

i thought about the 3.8 Supercharged from GTP swap for my GP before settling down on my LS1 swap... IN hindsight i should've went 6.0 or 5.3 turbo'ed... it was just as complicated to to that swap vs the ls1... and i had to contend with the supercharger facing the firewall....from i gather biggest issue with direct injection is the fuel system... :?

What happen to the 4.8 turbo you kept talking about?

I still have it but i trying to decide if i should install in it in my trans am or not.I had always toyed with the idea of getting a 6 banger from day one but i had got the most awsome deal on a complete low miles 4.8 ended up with that.but for some reason the idea of a turbo charged v6 at 500hp is just idk more exotic.

Hmm My suggestion is wait for the new 3.6 Twin Turbo motors caddilac is making and buy it Crate from GM?? can you say modern day GN? :lol:
