I own a second 1987 GN in addition to the one featured on this site. It is a high-mileage car (175,000) that I purchased in 11-second form in Jan '98. It serves as my co-daily driver with the Silverado. I grew tired of a variety of tranny and engine-related nuisances so it got an overhaul. The engine received a number of hand-me-down performance parts from my faster GN and I bought some other stuff for it, too.
I installed the rebuilt engine in October 2000 and swapped in the tranny from my faster car at the same time. The tranny had a 2-3 flare that got worse until the tranny gave up in Feb '01. I sent it to Mike Kurtz to rebuild it, including a billet forward drum/intermediate shaft and input shaft. After abusing it at a couple of races, I pulled the engine for freshening in summer 2002. It didn't take long after that for a stock piston to come apart at the track, and the rod broke into the adjacent cylinder. The block was destroyed and the turbo damaged. In May '03, the car was running great again, with the original ported stock heads and stock block from my faster GN installed (with TRWs). The hand-me-down parts from my faster car are: heads and intake, roller cam/lifters/rockers, intercooler, turbo, injectors, DFI and shocks. Here is a summary of the current build:
Engine: Stock block and rods from my race GN (bought that car new), steel center mains, TRW pistons.
Heads: Ported stock (Lingenfelter port, 1993).
Intake: ported stock lower, Hemco upper.
Cam: Comp Cams 210/206 roller and 1.65 T&D roller rockers.
Turbo: LT70, P-trim, 0.82 A/R, 3" inlet (built in 1996).
Exhaust: Poston headers, Terry Houston downpipe, ATR 3" singleshot.
Intercooler: CAS V2.
Cooling: Kenny Holm 3-row radiator, dual Spal fans.
Fuel: Sequential DFI, 72# injectors, in-tank double-pumper.
Tranny: PMAC 2004-R tranny, AC 16930 9" NL converter.
Suspension/wheels: Bilstein shocks, VR rear springs, air bags, Weld Pro Star wheels, BFG radials, M/T ET Streets or M/T slicks.
I don't spend much time racing/tuning this car, but I do drive it a lot. At a Streetcar Shootout in September 2001 (density altitude 4800 ft.), it ran a "traction-limited" 11.02 @ 124.0 at 25# boost on ET Streets, and ranked #2 out of 79 cars. After putting 200 miles on it after the '03 rebuild, I babied it down the track for 11.50 @ 120 (May '03) at only 18# boost, soft launch (1.85), with the density altitude measuring 5100 feet. Then, I won the "X-Treeme Automatic" Heads-Up class in Summer Street Wars in June '03 at the same track with 11.09 @ 123 at 24# boost, still launching softly on DOTs (1.70), and this time the density altitude was 6620 feet. This combination was good for mid-10's with more boost in my other car, so the performance is where it should be.
In October '04, I drove the car to the track with ET Streets, put some good fuel in it and ran a 10.99 @ 124.7, density altitide 4800 feet, and, as usual, poor traction (1.75 60 ft). It ran 10.95 @ 122 in December but bent a valve during the run.
