new engine mounts
new spark plugs

I don't know how many hp my current mods give (intake + exhaust), maybe 5 ahah^^ but I want a little more :)

I want to now what should I install next ? I don't want to delete the Cat, don't want any trouble with inspections. I don't have the cash for S/C or turbo, just want some parts to upgrade engine HP/Torque.


thanks for help !
Add a set of Crane cams & a 23st exhaust manifold. Flows better than the log you have now & the cams will wake up your performance.

I have NO cats. Header to flex to resonator to tip. If you get a tune it will cheat the missing 02 from removing the manicat due to a header. I'm debating on cams right now. Trying to figure out if the power gane is worth the cost. A tune is a MUST if you want to optimise your upgrades and the driveability is MUCH better with a tune as well.


If I win the lottery tonight I'm gettig a 2.3 dropped in with a turbo.
