So I'm getting back in the game after 6 years off with my GN. I decided after seeing what's happening in the industry, and the amount of money I've already got in my grand national, that doing the LS twin turbo setup would be the best overall choice moving forward for me.
Here's my dilemma since I don't know much about doing an LS swap.
1. A local Speed Shop recommended I buy a used L76 engine and harness instead of putting together a new LS2 engine piece by piece. I know it's cheaper but after upgrading it with rods, pistons, bearings etc it doesn't seem like there's any real advantage time wise or money-wise in doing that. The Holley computer is the only price part that would appear to be the difference.
The L76 engines used are around $2500 to $3500 with the engine harness but missing usually some accessories. Then these engines need to be rebuilt cuz they're usually 60k to 120,000 miles on them as I'm not risking a turd engine at start up.
What do you think about the above, am I missing something in their thinking aside from time convience and a little short term $?
Here is my initial plan with NEW parts....
Holley Dominator = $2000
Holley Unterminated Harness = $320
LS2 block = $1150
L92 heads assembled = $1200
LSXR 102 Intake/TB = $1300
Stock LS2 Crank = $315
Eagle Rods = $450
Pistons = $400
ATI Damper =$400
Twin 62/66mm T4 Turbos $1050 each x2
CX Racing G body LS Twin Turbo Headers/DP/Wastegate Piping = $1000
Tial 44mm Wastegate = $370x2
Tial 50mm BOV = $260
Fast Fuel Rail = $200
Holley 120lb Injectors = $360
LS1 late 90s water pump = $180
Then I'd still need pulleys, alternator and other things like sensors Etc so I know it's going to be over $10,000 minimum on just the parts. Selling my GN stuff will get me close to this part scary enough.
Is it a better idea to buy the L76 and then have the Machine Shop go through all that or should just buy all the new parts and have the Machine Shop assemble with new parts etc?
The Speed shop thinks L76 with harness and using stock computer to flash tune but I can't see that being great for 1,000hp and E85 with the 4L80 trans in the future.
I plan on using my beefed up 200-4R trans for the early stage and then going 4L80 later to save time and $ now.
