i got an 88 xj with a I6 and im looking into buying some performance parts for it, what do you guys think will get me the best bang for my buck? i was thinking a new COI and ignition system, but beyond that i dont know much for performance upgrades.

i did a air intake ,neon injectors ,and regeared a header will be in the future but for now a free flowing exhaust for now not alot of aftermarket parts for renix, unless you fork out the money for a renix srtroker motor

really the only thing you can do is add a free flowing exhaust and better flowing intake?TB. Neon injectors will give a bit better throttle response. Other than that the Renix 4.0 is hard/not worth the cost to upgrade. It simply wasn't designed as well as the later 4.0L engines.

This should give you a good idea what *can" be done with the intake

60mm bored TB from strokedjeep.com, upgraded multi-hole 19# fuel injectors, tune up (oil change, spark plugs/wires, cap/rotor, o2 sensor) custom downpipe without crease in it, replace cat if necessary, free flowing muffler, I prefer Magnaflow or aero turbine.
