I have every spec on this engine all on paper. If you want to know more detials let me know! Engine was built for a lot of nitrous as you can see. NEVER BEEN SPRAYED ON! Nitrous has never even been on the car at all.
Top end work was done by Brett Land at Landspeed Development out of Indianpolis, In (former Katech employee)
L92 heads with Bretts stage 3 port job
Ferrea hollow stem 2.165 int. valves with flow modified angles (nitrous finish on chambers)
Ferrea 1.600 exhaust valves
Stock l92 rockers (would be a good idea to have the trunions upgraded)
Bullet custom grinded cam 238/250 .643/.620 on a 114 LSA
Patriot double springs (good to .675 lift)
Titanium retainers, locks, locators, and seals
These heads flowed over 370 CFM's!
LS3 intake with Bretts stage 3 port job as well (custom throttle cable holder since the ls3 is originally made for a drive by wire setup)
FAST big mouth 92mm throttle body
Custom 4in intake with ls2 maf along with the ls1-ls2 maf adapter
Red aluminum catch can
Fuel Support:
72lb injectors from Fasterproms
FAST ev6-ev1 injector adapters
Walbro 255lph fuel pump
This car has been on e85 for almost 2 years now. Stock fuel lines are still fine with no leaks and support this big engine nicely. If you wanted to spray the car you would most like need to upgrade the fuel system to support the e85
Drivetrain:
2006 GTO Differential
Spec 3 clutch and flywheel just installed with engine 5,000 miles ago
Difftechnics 3.91 gears
BMR drag bags
Peddars urethane differential mount bushing
Exhaust:
1 3/4 Stainless Works longtubes
3" piping into 3" dynomax pro bullet race mufflers
The exhaust setup is very loud right now. I would suggest an X pipe if your going to drive it on the road a lot.
Brakes:
Slotted and Drilled rotors
Front pads are still good, just changed the rear pads and have an extra set to go with the car
Visual:
17x 8.5 ADR M Classic's in black (10lbs lighter than stock)
06 black tail lights
Xenon HIDS
Foglights have blue colored bulbs, not sure of what they are they were in there when I got it
15% window tint
Could use a set of rear tires.
I have changed a few things after the dyno. This being the 4in intake with ls2maf, and the exhaust setup. It was prior tuned speed density. The overall stoich has been adjusted but it really should be retuned since the exhaust change alone is drastic because of my previous choked up setup. I would imagine the car would make closer to 550 now with this current setup. I drive the car daily and its pretty easy to drive. Runs on e85 and will be sold that way. I wouldnt put it back on reg oct because of the compression but thats your choice to choose if you buy it.
There is a dent in the front fender by the headlight. It may pop out but ive never messed with it. There is also a scuff on the rear bumper. The car is an animal and is super fun to drive. You can call or text me at 765-337-4393
or just send me a pm on here.
I am not interested in trading unless you are giving me $10.5 with your trade. Thats what I still owe and it would need to be payed off. Interested in stock ls cars or street bikes
