can I get some opinions on this , just going to be a daily driver with some bolt ons for now possibly awd its for the truck in my project gallery

 

Why not lq9/80E combo?

 

just picked up a ly6/6l90 combo out of wrecked 08 sierra its in my classifieds would love to put it in there , smokeshow is saying its alot of work but i think it would be worth it ? I do have a 4l80 laying around also

 

You could sell it and buy a different combo, have just as much power, and save a few headaches. Smokeshow is a knowledgable guy. What kind of truck are you wanting to put it in?

 

I would sell the 6L90e trans.

To get the Ly6 to work, you need to get a few things. TooTall gave me the list on my Ly6 thread

90mm DBC Throttle body
58x to 24x converter from

knock sensor relocation harness
Injector adapters - Injector Connector Conversion Adapter Harness LS1 to LS2-EV6 USCAR

To go from a 4 to a 6 speed, I would not try that on my 08. I saw 1 person here do and it is possible though. Iamkniff is the name i think

58x to 24x converter is 258. alone cant i just get a tune to unlock/get rid of vats and run the whole set up only thing im not going to use is the vvt

 

You could do like Speartech did with their 2001 model installing an LS2/6L80E combo and piggy back the system. The old computer was retained just so that all of the gauges and A/C would still function properly. They built the harness(s) required for the swap. About the only extra item you should need besides the ECM is the ETC accelerator pedal.

 

Exactly what I did.

 

Nice, thanks .

 

get the whole harness and tcm and it will be perfect and fast,thats the same combo i run
