I think a 1jz would be more fit for an xj lol

Just remember if you over heat those engines their done. The apex seals are what you really want to watch out for. They also have to be rebuilt around 80k to keep them in good running condition. If you think a xj is bad on replacing parts just wait. I would try to find someone in your area that is good with the rotary engines and have him check everything out.

Awesome info thanks that the kinda advice I like to get. Also any wiring advice would be awesome as well.

96xj_2whlr

I don't know very much about the wiring, but deffinatly don't skimp on the cooling system. My brother wrecked the front end (Doing doughnuts) of his after we had gone through it with carlos and replaced all the bumpers and apex seal and overheated it and it was like starting from scratch with the engine. almost every seal had to be replaced.

Oh damn def not gonba skimp on the cooling system then

And the apex seals are only good for 50k if you baby it 10k if you drive it like you stole it.The hillbilly iin me screams throw a big block in it.a 460 or 454 can be had cheap they both was used in 1 ton trucks deep in to the 90s,Or a caddy 500.If you want gas mileage and some power a ford 2.3 turbo could be fun to have.

I drive everything like I stole it lol. Big block would be fun but wanted to try something different.

i wouldnt put a rotor in something that weighs as much as a cherokee. not that cherokees are that heavy, but that motor came in a car that weighs 2500 or something lbs. i would go with something with more torq like the chevy 4.3 vortech or ford 4.2 or something along those lines

The lack of low end power in a Wankel engine makes this quite possibly the least appropriate engine for a jeep. They make Hondas seem like torque monsters.

A turbo still need to be spooled up, if you want big power from a big turbo you're going to have massive turbo lag. If you go for the faster spooling action of a small turbo your end gains will be much lower.

If you are set on the rotary path, familiarize yourself with "oil blow by" and be aware that they consume oil at an alarming rate.

Slim357

Ya I know they eat alot of oil but from what I understand from what my buddies have told me they are designed to do that. Main reason I'm thinking about doing it is because its something I have not seen done before or much less even heard of being done before

Sometimes there's good reason no one has done it before.

If I were set on swapping a Japanese motor in, I'd be thinking more along a Subaru 2.5 turbo from an sti or a K23 turbo from an Acura rdx. You'd make more power more reliably and wouldn't have quite as much issue with low end torque.

If you want to be different look at a rb25det or build a rb30det.Or a toyota 1uzfe its their v8 reminds me of a ford mod motor kinda.

Talked to my brothers mechanic carlos about the swap and he just shook his head and said " crazy a-- white people". He was worried about the power-to-weight ratio.
