increasing 98 performance

[anthonygubbin]

Hi guys I have come across random posts mentioning a few things to improve performance on the XJ's. Can anyone tell me what these mods are. I have read somewhere about ignition upgrades, headers and manifold. I would be interested in some ideas around the ignition coil upgrade. Headers well they are self explanatory and will be done when mine crack. Is there anything else I have missed? Injectors can stay the way they are for now as I run LPG. I may look at an upgrade to gas injectors and the other bits later down the line once the rebates disappear and competition returns to the LPG parts market. But my guess is there are a fair few other upgrades but they don't often get a mention on here.

regards A

Headers, and a bigger throttle body. Don't bother with chips, most are a waste of money on the old 4.0
The Diablo tune module has shown some good results apparently though, but not cheap.
