What engines have you put in your CJs?

Just curious. This all came about when someone told me they put a dodge neon engine in theirs. Or, at least that whey he told me.

Hey,
Just got done installing a small block chevy into my 74 setup this past sunday. I used a noval adapter kit and motor mounts and everything went smoothly. A bit more welding and she'll be ready to roll

I was thinking of a 'simple' 4.0 swap, well, actually have my mechanic friend do it, and buy him lots of beer.

dodge neon swap?

thats funny, cause we were actually looking into the neon head and performance parts to try a nd pep up the 2.5, the neon is a 2.4 we figured they were the same block so the parts would also be universal/interchangable.

That's a negitive, ghostrider, the pattern is full.

Neon is a 2.0
The 2.4 is a 1" larger deck height. Bore on the pistons is the same.
The Dodge truck 2.5 is a diffrent beast.

The 2.0 and 2.4 can swap heads. Base neon (from 95-now) offered a SOHC head. From 95-99 you could find a DOHC head. In 00-now a SOHC Magnum head was offered that has larger exahust ports. Starting on 03, the SRT was made with the 2.4 Turbo that's also found in the PT cruiser. This is about the same DOHC design as the 2.0 DOHC and the 2.4 DOHC (that can be found in the stratus, PT and minivans in NA form) Good luck finding any SRT/Turbo PT parts in a junkyard. Neon people tend to snap that up super quick.

The dodge 2.5 is closer kin to the 2.2 of the 80's. If you find an old turbo 2.2 or 2.5, that would be a better pull for performance parts.

The 2.5 used in the dakotas and such was put into use around 1995. This is an AMC design. Far diffrent from the neon 2.0


If you have any more information on the neon/cj swap, pass it my way. I got a spare engine and I'm almost crazy enough to do something like that.

The neon engine is probably about the same HP as the 258 and is fuel injected and much better MPG. But...

Would it even work? How would it mate up to the tranny?

Yeah, with about half the torque...and what little it has in all the wrong places. It'd be like driving around with a Singer sowing machine under the hood.

fuzzy, why not just go straight to a 351W? They fit in the same hole. . . 351 is about an inch taller and wider than a 302.

I don't do Jeeps, but i'm here to help.

Remember, anywhere a car can go a 4x can go, only slower and more deliberately. The ONLY advantage of a 4x is to be able to go where the car can't.

302 Free from dad = $0
351W from wherever = some amount of money I don't have to fork out.
