OMG, I'm going through another phase....
Anyway, tell me about the ZR1-specifically 1991.
Wiki:
During 1986, General Motors acquired Group Lotus, the UK based engineering consulting and performance car manufacturing firm. The Corvette division approached Lotus with the idea of developing the world's fastest production car, to be based on the C4 generation Corvette. With input from GM, Lotus designed a new engine to fit in place of the L98 V8 that was powering the standard C4. The result was what GM dubbed the LT5, an aluminum-block V-8 with the same bore centers as the L98, but with four overhead camshafts, 32 valves. Lotus also designed a unique air management system for the engine to provide a wider power band by shutting off 8 of the 16 intake runners and fuel injectors when the engine was at part-throttle, while still giving the ZR-1 375 hp (280 kW) when at wide open throttle.
I can get this one for a pretty fair price (I know the owner):

Absolutely the pinnacle of the C4 technology, and a world-class car.... for the late '80's/early '90's. Nothing is a problem on that car, except the engine. Not that it was a problem, but parts are. I know a couple of C4 ZR1 owners, and they have to buy up whole engines/drivelines for parts, because new parts just do not exist (blocks, cylinder heads, etc).
The engines were designed by Lotus and manufactured by Yamaha. There haven't been any new parts made in over a decade, if I remember correctly.
That being said, if I could find (and afford) a red 1990 ZR1, I would park it in my garage and put a prayer mat next to it, and tell it how beautiful and awesome it is every single day.

I thought Merc modified them?

In my honest opinion, I would spend 5k more and get a 2002+ Z06. No need to worry about replacement parts for a Z06.

i wouldn't buy ANY corvette from the early 90's.

You're absolutely right, I believe, I was thinking of another engine made by Yamaha.... Merc made the LT-5 engine from that gen of ZR-1.
GM didn't have any supplier at the time that could do that multi-part aluminum intake. So Merc got the job.

I believe you were thinking of the old Ford taurus sho.

Okay. I'm over it. Whew! Glad that impulse was brief!

lol
Ballooning next then Mr Toad?

Rip,
I always thought those ZR1's had a special nickel alloy block that merc had to machine for GM. I can tell you they are a nightmare to fix and parts are easier to find on an old BMW507!
I think Reaper might have confussed the "ford" yamaha engine with the vette's,Ford got Yammy to build the V6 in the SVO taurus,another nightmare to fix!
IIRC the Zr1 had the first "Vallet" setting on the ignition so you could detune the engine and limit the power output. Oh and I think there was a reason it was only built for 1 year......... :devil

But it does have a CD and cassette tape player. How cool it that!

From what I understand on the Corvette forums, A total of 6,939 ZR-1s were manufactured over the six-year period.
And, you're probably right about finding parts for a Lotus-designed engine. :uhoh

I thought it was Mclaren that did the work on that engine? I was talking about that motor when I said they built the ZR1 only 1 year,I meant with that motor.
I'm almost positive Lotus has tyes to Ford and not GM,I could be wrong with the way the buy and sell marques but lotus used Ford power for years.

Well, I'm no expert, and this was the wiki entry. Shrugs.

The Corvette division approached Lotus with the idea of developing the world's fastest production car, to be based on the C4 generation Corvette. With input from GM, Lotus designed a new engine to fit in place of the L98 V8[citation needed] that was powering the standard C4.

In addition to the engine, Lotus helped GM design the ZR-1's (which in prototype version was called "King of the Hill"[4]) upgraded braking and steering systems[citation needed], and helped them pick the settings for the standard "FX3" adjustable active ride control that Chevrolet was fitting to the car[citation needed], helping to ensure that the vehicle was more than just a modern-day muscle car with a big engine and no real capability on the track.

irs Wikipedia. If you edit it to show mclaren instead of lotus you will look like an expert. ;)
