Lq4 6.0 Swap On A 5speed 1500

[dunesdude]

Hey im in the market for a 1999-2006 sierra/silverado 1500 5 speed manual 4x4,Im plannng to swap in a lq4 or an lq9 from a totaled denali or escalade as soon as i find one . anyway what i want to ask is what parts do i require to swap from the 4.8 or 5.3 to the 6.0 also are there any drivetrain differences between the v6,4.8 and 5.3 because i searched and found out that they all use the same transmission (NV4500) and transfercase so if im gonna do an engine swap it might be cheaper to start with a v6 or a 4.8

 

thanks

You definitely don't want to start with a V6. You'd have to change motor mounts, PCM, wiring harnesses, etc. whereas when you start with a V8 it should just be a drop-in replacement re-using most of the original parts (even the accessory drive can be re-used). You WILL have to re-tune your PCM for the 6.0L engine's parameters, but past that you'd be in good shape.

To go to a 6.0 you would need to get a new trans. (4l80e) to handle the power. I'm also pretty sure you'd need a new transfer case. The rear ends are also different as the 2500's came with a 11.5" 14 bolt. Just some things to consider.

He wants a manual trans.... and the NV4500 should be able to handle it fine.

I wouldn't suggest an 80e transmission, just get a beefed up 60e. The 80e will result in power loss down low due to the gearing.

Both the 4.3 and 4.8 powered 1/2 tons that were available with a 5 speed originally used the NV 3500....... not the NV 4500 transmission. The 3500 is not an overly robust transmission so I would be careful with putting a lot of power to it........

i had a 2002 sierra single cab short box step side 4x4, came with 4.8 wtih the nv3500 5 speed. i blew that motor up and swapped it for a 6 litre lq4, port and polished heads and a mild cam. never had an issue with tranny really. just changed oil often and ALWAYS use the DELCO syncromesh, not the cheap stuff. at about 200k kms i sold her. had the 6 litre in it for 100k kms. when i sold her 2nd gear syncro was gettin pretty rough. but thats not the trannies fault lol. and thats with a hd sachs clutch, rear locker, 33 x 13.5's and a little bit more power than stock. the tranny never pooched out on me. over all i think you wil do fine with an nv3500 man, just servicce it and dont powershift every time your in it LOL
