1987 Performance up grades!!!?!

[SeniorGustas]

Hey, guys so my 1987 xj no longer has to go to emmisions testing. I know theres a whole bunch of stuff in there just to control pollution, because on my dad 1986 toyota pickup he cleared out about 30% of his engine compartment with things he didnt need along with adding a new carborator. And it runs way better now and sounds great. :D Now i've searched and searched for what i cant take out but have no idea its 2.5L 4 banger fuel injected. If any of you guys know what i can take out id really appreciate some information and pictures are always extremely helpful! thanks Guys :anyone:

Nothing that I know of.....

The best you can do with a 4 popper is lower gears for more 'power.'

Then roller rockers, header/exhaust, CAI. But these last things listed.....installed, probably will not feel a difference.

Drive it and enjoy the mileage!
