Some questions about the different years - Page 3 - ZR-1 Net Registry Forums

Can't answer your question to regards of comparing to the foreigns you mention.

What I can say is as far as performance....it's really dead even for safe sake. Stock for Stock

The major difference is feel in the cockpit due to the seat changes from 90-93 to 94-95. It's going to come down to your feel in the piloting seat.

I for one love the earlier seats once your in them. Getting in can be a difficult task depending on the size of the fellow. The later seats are much easier to get in but not as much upper body support.

This is all based on my opinion and having owned many C4 cars over the years.

The best thing for you to do is decipher price range and start searching! We/I will not be held responsible for ticketing that may occcur from excessive usage of the secondaries!

I cannot relate to the RX analogy, but if you refer to Marc's web site, you'll see
that with the "full Montie", both motors 90-92/93-95 are equal.

a 1990, if it has had a plenum and injector housing port job, long tube headers and the usual mods that alot of them have, will not give up anything to a 93-95. The 93-95 are usually more money unless you get a car with some mileage. There are plenty of 1990 and 1991 that flat out fly and the 93-95 have nothing on them. the extra horsepower of the 93-95 came from tuning and a little better intake flow from the factory and maybe a little bit of cam timing etc.. not much at all. A 1990 and 1991 with an intake port more than makes up for that hp difference and you can bet a much better deal because they simply made more of them. I would have never bought my 1990 if I thought for a minute my engine was inferior in any way to the other lt5. You most important task is to find a good car and hopefully with some good mods, not trashed and ready to go. If you can get one with intake plenum and injector housing port along with head porting then you got a winner. there has been one for sale in this forum for some time in arizona.
