Complete 2005 LLY swap done to 2001 LB7 truck!

[MACKIN]

How come you didn't just swap out the heads like others have done? Yes I know a little more to it then that but you know what I'm referring to. The LB7 motor seem to be the motor of choice.

With EFI you could not run a very similar turbo on a LB7? Nobody wants a LLY except for Ben. LOL

the biggest reason I wanted to complete LLY type like this is to be able to run a LLY turbo. I want to do some work stock truck pulls, in which you can only run any stock size duramax turbo. as u prolly know that LLY turbo is the biggest stock duramax turbo. also then since im running LLY ecm and ficm its exactly the same as tuning real LLY truck.

Oh OK I guess I understand it's the "rules" meaning stock so even if it were a identical sized LLY turbo on a LB7 motor it isn't stock on a LB7. Do they really check vin codes and they will take your word for it that it is a complete LLY even tho it's a 01?

 

[bonomax]

Yep must have stock size compressor and turbine wheels but can be different geometry blades configuration. No sorry, I didn't mean they check the Vin. Like any duramax truck can run any duramax turbo.

Coulda just had Ben develop a VVT controller to compete with the other one on the market.

Yea fleece used make one but if something goes wrong u can't just run to the dealer and order replacement like if u do complete lly swap like I did

LLY > all ... punk

 

[bonomax]

i have to agree that I like the LLY motor much better than LB7. in my opinion it starts much quicker, easier, heats up quicker, runs smoother, better turbo, injectors, heads, etc...

Bingo

Don't flatter yourself, you still got the lbz, lmm, lml that are better

I will say that the 6 speed is nice.

Meh, my 5speed gets better mileage then the 6 speed trucks.

I was just busting your balls I really don't like anything about the new ones at all

So its been a couple months, how is this setup running and working?

 

[bonomax]

No problems what so ever. did few 4wd launches got zero to 60 in 4.5 seconds, pretty consistently. Thats Even on ez launch conly like 1500rpm at 2.5psi boost. my trucks pretty heavy too. like 7500lbs or so because truck cap and stuff.

 

[mgramke1]

Very awesome! Liking the lly?

 

[bonomax]

Love lly vs lb7. Turbo pulls harder low end and smoother power even lowest tune, warm up quicker, on and on. Very happy with the results and def do it again.
