Bought this GN in 2009, it had sat in someone's garage for 9 years. Stock engine had a very loud valvetrain and a wiped lobe, the stock turbo was on it's last leg too. One thing led to another and I ended up rebuilding the whole drivetrain. Finally it's ready to hit the road.
New Look:
3 year long project rebuilding the engine/trans, new turbo, etc..., details:
Engine: 109 block .030 over, Blue printed race balanced, Steel crank, Steel rods, Forged pistons, 2 steel center mains, Disassembled, cleaned, new seal rings & new bearings, 212/212 Comp Roller Cam, hi rev lifters, pushrods, timing chain, Harland Sharp roller rockers, Ported Weber iron heads, new exhaust valves, springs, retainers, locks, seals, & shims, Decked flat and cleaned up pedestals, Cometic head gaskets, Refurbished exhaust headers with new hardware, Siemens 80 lbs injectors, Billet adjustable fuel pressure regulator, HRParts heavy duty motor mounts, TA valve covers
Turbo: PTC 6262 Ball Bearing Turbo with .63 exhaust, ported S cover, HD wastegate
Intercooler: Precision SLIC intercooler (stock location)
Electronics: Extreme Extender chip, Powerlogger & Scanmaster, Fuel & alky pressure transducers installed and connected to Powerlogger, LT1 MAF, Translator Plus
Gauges: MTX-L Automotive Wideband A/F Gauge Kit, Autometer Sport Comp II Gauges-Boost/Vac-Water Temperature-Oil Pressure
Methenal Kit:Alky Control alcohol injection system
Exhaust: Terry Houston 3” downpipe, ATR 3” race pipe, ATR 2.5” exhaust
Suspension: Bilstein shocks, rear seat brace, new body bushings
Transmission Upgrades:
HDS Hardened Stator, Wide Alto red lined band, Shift Kit, Transgo pump ring kit, 10 vain rotor (pump), New pressure regulator valve, Line pressure regulator spring, Line pressure boost valve 0.500, 2nd reverse boost valve 0.300, Alto race red clutches 3rd & 4th, Competition Valve Body, Pan Spacer & 700 4R Filter, Hayden transmission Cooler
Wheels: Budnik Tillers, Front: 17 x 8 with 4"bs 245/45/17, Rear: 17 x 9.5 with 4.75"bs 275/40/17
Other Upgrades:F-body radiator, Duel SPAL fans with new wiring harness, converted to vacuum brakes
The GN is tuned for zero knock wtih 25 psi boost, this thing scares the hell out of me at WOT.
