Camshaft questions

2001 xj with basically a stock engine

Im looking into a bigger cam, found the one id like and i have a few questions.
http://www.summitracing.com/parts/CCA-K68-239-4/

It says No for computer-controlled compatible, look at the applications it says it will work in a 97.
What do i need to do to make this cam work in my xj? 97 computer swap?

I have a bored throttle body a 95 cylinder head im going to get a header and port the head.

Any other information or ideas would be great. Thanks in advance.

Why are you looking at a cam ? The Jeep 4.0L already has lots of low end torque.

Installing a cam is not a one step modification, you would need to address intake, fuel injection, and exhaust modifications at the same time to achieve any real benefit.

You should look into building a Stroker Motor instead. Just Google, there is plenty to read.

I understand that. I'm basically asking about the fuel injection part. And I dont have the money or space to do a full engine build.

So, you're looking at pulling the entire front of the truck apart, pulling apart the front of the motor, taking out the rockers and pushrods (at least), replacing the timing chain, and then replacing the camshaft (assuming there are no problems) and you say that you don't have the space for an engine rebuild?

It's true, you never forget your first Jeep. - 1999 Cherokee - 188,000 miles. DOA.

Then you should look at a Catback exhaust, a K&N style air filter, and a bored Throttle Body.

I am not an engine builder, but I don't think the 1996+ OBD-II would be able to deal with a performance cam and no other modifications.

Those application charts are not always correct.

Yea dude. Forget the cam unless you're doin' a 4.6L. Do the 99+ intake, EV4 Neon injectors, borla headers, 2.5" exhaust, 33's and re-gear to 4.10's and THEN see if you even need a cam.

Tim I addressed that in my original post. I have bored tb, I have the high flow 95 head, im getting a header, and I'm porting the head as well. I also have a cold air intake.

I don't have the ability to pull the engine at home. I can do everything else. The front end is torn apart already. Quarter panels and all. All I need to know is what needs to be done to run this cam without switching to carbureted.

If it says it won't be compatible with the factory computer you'll need to either buy one this is or find an aftermarket computer that is compatible. I don't think that cam is the best choice for an otherwise stock motor at all though. You'll need a fully ported head, probably bigger valves, valve springs matched to that amount of lift, it says you'll need a double roller timing set, probably a cooler stat & 3 row radiator to make it all work together and even then you'll probably just blow out the bottom end in a few months if it not beefed up as well not to mention the possible emissions/inspection issues and CEL lights your sure to get all the time. I think your just asking for headaches but if you really need it and have the cash to do it right make sure you do a build thread so we can see how it turns out. I'd be interested in seeing it.
