Early (pre 1991) 4-cyl engines were fuel injected via throttle body - 2.5L
Second gen (post 1992) 4-cyl engines are fuel injected via MPI (Multi-Port Injection) - 2.5L


Early (pre 1991) 6-cyl engines were carb'd - 4.2L
Second gen (post 1991) 6-cyl engines are fuel injected via MPI (Multi-Port Injection) - 4.0L

And of course the TJ's and LJ's are also EFI'd.

That info would be on the YJ, FYI.

That info would be on the YJ, FYI.....and it would apply to the TJ and LJ since they're post-1991 ;)

I personally prefer the TJ's (97-06), but I am biased since I own a 98.

I wouldn't mind owning a 91-95 YJ, but only for a part-time vehicle. I feel the TJ's are much more practical for everyday use.

I prefer the V8 CJ's 4X4X304

I don't know if the wranglers used the 0331 heads nor do I know if you want to buy that new of a vehicle, but the 99' 00' 4.0s with the 0331 casting head had problems with cracking. You can identify the head by looking inbetween the #3  cylinders on the driver's side of the engine right beside the valve cover.

personally i like the cj's look more "jeepish".

IN XJ's, should this come up, the 2.5 went from carb to TBI in 86.
