With the possible exception of Hesco the others are going to be in the $125-150 range so it makes little difference. Hesco does specialize in 4.0L engines and makes a great stroker themselves. They ship worldwide. Call them if their e-mail isn't answered promptly enough. (205) 251-1472. If I wanted any kind of performance changes to my 4.0L Hesco would get my business. But that is JMHO.

Blue, I know you are a Renix man. Do they offer anything to hop up the Renix era XJs?? Thanks!!

BlueXJ

You can get a bored TB and headers. More than that will be an expensive proposition. Cam, thinner head gasket and reduction in head thickness(milling) are always an option as on any engine. After that you can adapt the H.O. TB and intake to the Renix but we are talking about spending as much as a Renix XJ is worth to make those kind os alterations. And finally there is stroking and supercharging both of which are available through Hesco.

where can i get the closest to stock cam? and a timing set?

kmanxj5050

how many cubic inches is a 4.0 (in an 01 if it matters)? 242?

BlueXJ

I think that is the correct cubic inch number. As for stock cam I would look into Crown as they may have what you want. Hesco makes the best as a performance cam but you need to call and speak to Bennie at Hesco he will be able to make suggestions depending upon your particular needs and requirements. (205) 251-1472

There is a vendor here Gerr who has a crown dealership. His prices are good and his reputation is also good. Try him first then see if you need another link. He can be located on our vendor page.
