Started the supercharger install on 09 G8GT this past weekend, would have finished had I not forgotten to order intake manifold gaskets. Picked those up today and should have the top end all together tonight.
LSA 1.9L Supercharger
ZL1 Lid
LS9 Cam
60# Injectors
Zl1 Pump
LTH and 3 inch exhaust
ATI Damper with oversized pulley (10psi)
This is daily driven year round so not looking to break any records, just a reliable quick car that surprises people.
Random pic of turbo that was on my cavalier back in the day
Headers modified with Flomaster Cats
finished exhaust
Stock breathless L76
new cam going in, ls3 valley cover installed
Started buttoning everything up, ls7 lifters, heads, and front cover installed right after this pic
My buddy has this same setup with H/C/stall auto/e85 just went 11.2 @ 131 with a 1.8 60’
He did have to do some heat exchanger upgrades whatever comes with the kit wasn’t enough if you run into any issues let me know I can put you in touch with him he did everyone on his own and had to work out a few other small things.
do you have to do any spacing for the belt/ac stuff? I think then I looked at the lsa blower on top of a ls2 motor there were a few obstacles. was already a tvs1900 and after thinking about it I just upgraded to a tvs2300 which made things much easier.
one pulley needs a washer to keep from interfering but other than that its all of the pulley brackets from the ctsv. The water pump has to be swapped to an ls3 style as well to clear the blower snout.
Got mine for 350 shipped. Was being sold as-is for parts on ebay because of the isolator rattle…replaced that with the solid one from lingefelter for $50 and its all set. Even came with all the sensors.
the hardest part about this swap is doing the cam. So if you have everything apart you might as well…
It does add some time, a couple pieces of the harness have to be extended, the power steering reservoir relocated, the coil brackets slightly relocated, the crank pulley pinned. G8Board.com has a bunch of build threads and someone even posted a pdf how to.
L76
The L76 is derived from the LS2. And like the LS2 it features an aluminum engine block. However, the L76 does feature Active fuel management (AFM). While the displacement on demand technology was disabled on Holdens, this feature is enabled on the 2008Pontiac G8 GT and subsequently refitted in the 2009 model Holdens with AFM enabled, but only on models fitted with the 6L80 Automatic Transmission. The engine also meets Euro III emissions requirements. Output is 348 bhp (260 kW) at 5600 rpm and 376 lb·ft (510 N·m) at 4400 rpm for the Holden variant, and 361 bhp (269 kW) and 385 lb·ft (522 N·m) for the G8 GT.[SUP][11][/SUP] The Vortec 6000 or newVortecMax version is based on the Holden L76 engine, and features variable cam phasing, along with Active Fuel Management. It can be considered the replacement for the Generation III LQ9 engine. It produces 367 hp (274 kW) at 5400 rpm and 375 lb·ft (508 N·m) at 4400 rpm. Production of the Vortec 6000 started in late 2006, and is only available with the new body style Silverado and Sierra. The final year for the option of the VortecMax engine was 2009 in the Silverado and Sierra. vin code (Y)
