Looking for an XJ approx '89-'95. What bolt on power is available in these years for the infamous 4.0? Best I can tell throttle bodies etc. start becoming available around '91 but I see several nicely built '87-89's.

Any help is appreciated.

 

i have a 1995 with a couple bolt-on options that give it a nice little zip. i have a 62mm BBK throttle body, aFe intake., did the exhaust with bigger piping and a Magnaflow (still want to do the header when i get the money), and when i have time and money want to replace the intake manifold with the '99-01 mani, and do a injector swap for the Neon injectors. i also want to do the fan clutch mod and replace it with the spacer, which is supposed to help give it some more power, as well as help with overheating issues that are known for with the 4.0L.
