ZR1 Corvette Nurburgring

Part of a lap at the Nurburgring in my 1991 C4 ZR1, not very fast as it is only my 4th lap, I eventually get fed up following the Porsche and try to keep up with the BMW that goes past.

The LT5 is not simply a LT4 with quad cams. The LT5 was engineered by Lotus and entirely different than the LT1 and the LT4 (which was just a buffed up LT1). LT1 engines were cast iron, not full on aluminum like the LT5's were. The LT5 was much closer in basic design to the L98 if anything, but engineered way more competently. Best motor made until the later LSX architecture. For their age, those cars and engines were bad ass. They still are today.

Its funny, I know every inch of this track and never been on it. Thanks to Grand Turismo 4. Nice vette bye the way.

@Artuir82 You're welcome. It's an interesting history because while many believe the LT5 is dead nothing could be further from the truth. Much of the technology that went into the LT5's heads later went into the Cadillac Northstar engines. One could even go so far as to say that the LT5 motor is the granddaddy of the Northstar motors & when Carole Shelby went looking for an engine for the Shelby series 1 it was not surprising to me that he chose a Northstar engine & then later supercharged it.

@bronxboyXXX Thank you for the clarification :D

@Artuir82 Not totally true. The reason the LT5 got the LT designation is because it shared the 4.4 inch bore spacing with previous LT engines. The first LT engine was the 1970 LT-1, the next was the LT1 II with reverse cooling & some parts are interchangeable. The LT5 was engineered by a team headed by Mercury Marine Project Engineer Terry D. Stinson & only the 32-valve DOHC heads were designed by Lotus.

it's awesome to know every turn, every curve and every piece of this track thanks to Gran Turismo 4. Thanks GT4! If I ever get my car there I'll be comfy as a kitten like I'd driven it 1000 times...haha.

i WISH i could take my rx7 there!

where is the super charger whine? think about that

Were did in the F*%#@ did you get that this was basically an L98 block? This is asnentirely different motor. Not one part was used fro the l98 except fuel injectors, but instead of 8 there are 16. I own one and it is a terrific motor.

Not quite, in fact, not close.. GM owned Lotus at the time, and Corvette approached Lotus to assist with the design of the fastest production car in the world. Over four years both Lotus and GM designed the engine which was eventually assembled in the US by Mercury Marine at Stillwater. So, Lotus had an important input; the DOHC in particular, but they certainly did not 'engineer the entire motor start to finish'

Love the motor. Lingenfelter has some amazing potent kits for this motor. They have a 475hp, 530hp and 610hp packages for the LT5.

The LT5 block is basically an aluminum L98 block, but almost everything else is different. DOHC, and 32 valves. The motor was designed by Lotus and was built by Mercury Marine. It was a very expensive motor to make and it was the only OHC V8 Chevy has used [not 100% sure, but I think so]
