1998 wrangler sport vs. 2000 wrangler sport

what is the differences between a 2000 wrangler and a 1998 wrangler in:
1) cosmetics
2) engine
3) transmission
4) smog crap that dramatically affects mpg??


so is the 2000 year model basically the same (performance and mpg) as 1997-1998 jeep wranglers?


Thank you guys so much!!!!

The 2000 would be a much better choice.

As it got a power boost, (190 hp, 235 lb-ft from 181 and 222) from what Rocky showed above- distributorless ignition is the big one. Also, in 99, there was a redesigned intake manifold

Plus you get the NV3550 over the AX-15

well, yea but the 1998 had far less smog detactors which allowed the 1997-1998 to be more powerful and higher mpg, i talked to a couple guys and they said their 1997's got 17+ lifted with 33's.


With the new cylinder head, didnt that make things alot worse, (MPG, power??) or did that not start tell 2001?



Thanks alot tho!!

The 97-98 weren't more powerful.

as i said:
97-99 had 181 hp and 222 lb-ft of torque.
00+ had 190 hp, and 235 lb-ft.

no, the new cylinder head didn't make things worse. The biggest gain was to be found in the new intake manifold though.

My 2000 window sticker said 16/19 for gas mileage. I get 17-18 mpg on 31s with 3.73 and the NV3550

Getting 17mpg on 33s has more to do with gearing and transmission and driving style than minor engine changes

your worrying about all the wrong things, lol.

the only difference, if any. is that the 2000 might have pre-cats that the '98 doesn't. But pre-cats are only useful on cold start-ups to reduce emissions before the main cat warms up, after its warmed up, the pre-cats are useless.

The earlier TJs had exhaust manifolds that are prone to cracks. The manifold was changed in 2000 and is less likely to crack.

Very minor differences between those years. Just buy the best vehicle if that's why you are asking.

Cosmetic/package wise yea, but drive train wise there were quite a few important differences.

My favorite part of the 2000 was the distributorless ignition and redesigned intake. You can't just swap the ignition but I did nab a 2K intake manifold. Bolted right up.
