An LS3 swapped 1991 Nissan 300ZX with a pair of Precision 6266's making 1000+ horsepower to the wheels
There is a reason LS swaps are possible. They work, they're reliable, they're fairly affordable, and they can make huge power. Purists may hate seeing an American V8 under the hood but the owner is making too much horsepower to care.
The correction factor on this Dyno Dynamics is not shown but quadruple digits are no joke. This is big, big power:
This swap is actually more popular than you might think and LOJ conversions offers a swap kit: https://www.lojkits.com/pages/300zx-1990-1996-overview
The engine certainly looks right at home:
As for the motor specs:
Quote:
The engine features a bored and honed head, JE FSR pistons, Manley Pro Series I-beam rods, 1250 HP Turbo camshaft, Manley Extreme Duty Series valves, Fast 120mm intake, and Nick Williams 102 mm electric throttle body.
The engine is fed by two Walbro 450 LPH E85 fuel pumps through Fast LSXR fuel rail and ID 1300 cc injectors. Two Precision 6266 turbochargers are mounted in rear of the car. The combination made the wheels spin on the dyno at 1,017 horsepower so they estimate it’s making 1,110 whp and about 1,287 horsepower at the crank
Awesome.
