Entire 96 Stroked Motor into 2001

[woodjeep]

Have a 96 stroked running in my 92 Cherokee...took many months to get the head/block combo correct..had many issues.. Its now running fantastic.I will get my sisters 2001 Cherokee this spring. I would like to just drop in my motor whole .I DO NOT want to separate the 96 head to install an easily compatible 2000 series head. I know the 2001 does not have a distributor, and uses a coil rail. I see this as my only real issue in the swap. Any way to go about installing her " ignition distribution " on my head without replacing it..Thanks

The only problem is the exhaust manifold. The stock 2001 manifold will intrude into the earlier head as well have limited sealing area at the bottom of the port. The easiest solution is to get a set of headers for the 2001. They will fit the port better.

The second issue, which really isn't a problem is the coil rail mount. You could run some straps from the valve cover "studs" to the coil rail. Or replace it with a Viper coil. Link in in my sig for that.

you will also have to change the injectors or adapt them to the new connectors, a couple sensors may also be different

Injectors need to be addressed, yes. As far as sensors use the one from the 2001. As well as the intake manifold, its sensors and the throttle body.

Thanks I forgot about the fuel pressure differences and matching the intake is no real issue. My exhaust is the APN exhaust manifold, but since I'm keeping the head do I need to change the intake and exhaust? or if I must change the intake to the 2001, can I match the 2001 intake to the apn exhaust I am currently using. I thought my difficult issue would be the distributor and coils setup.thanks...more research needed

I just looked at the Viper ignition link...I am unfamiliar with a distributorless ignition..even on jeeps. What does the new "distributor thing" plug into and does the viper coil pack just plug into an existing connector...or will it be fairly obvious once I start fiddling around with the 2001

The 2001 most likely has the Cali emissions package with 2 pre cats and 4 O2 sensors. The two upstream sensors are in the stock intake manifolds, the two down streams are after the precats. You need to take a look at the vehicle to see what I am talking about. To use the APN header you would need to have two O2 sensor bungs welded in for Bank 1 and bank 2 on the header. You would then have to remove the precats and do something about the down stream o2 sensors. Its much easier to just buy the correct header.

or if I must change the intake to the 2001, can I match the 2001 intake to the apn exhaust I am currently using.

the 2001 intake will provide better performance and the only matching that may need to be done is a slight dent in the header.

The coil rail/ coil pack plugs into the harness at the back of the head. You would need to extend the harness so you have more room to locate the coil pack. The wiring is just straight through if you use the Viper coil (also fits some Ram trucks). The distributor is replaced by a cam sensor. Check the FAQ section on how to index it properly.

Thanks..all this will probably make more sense when I start looking under the hood of the 2001..I didn't realize they were so different...the 96 basically interchanged with my orig 92..I think the PS pump and bracket was different and that was it.

on the exhaust you can get away with having the 2 bungs welded in your manifold for the upsteam then just change your downpipe. the downstream o2s you can just zip tie under the body somewhere as long as they read oxygen you wont get a cat efficiency code
