I have a 98 Mitsubishi Eclipse RS so its non-turbo. I've already put an intake on, a new muffler, and an ultra high-flow race cat, but I'm tired of doing small mods here and there. Does anyone have any ideas I can do to the actual motor itself (besides turbo or super charging) to make it faster. I was wanting to do some motor work, but I dont know my options. So if you have any ideas besides bolt ons like headers and stuff then leave me some suggestions..(oh yeah, don't suggest nitrous either, because i already have a nitrous express kit, its just not on yet)

8.8:1 CR pistons
Head resurface and acid bath/cleaning
Re-ground valve seats
3 Angle valve job
New valve stem seals
Bore
Polished crank
Balanced crank
Machined lower end of block
titanium retailers
forged rods
port and polish intake manifold

Wow, that's a lot of options :) . What are we talking as far as price range of these ideas and actual performance gain? Which would be a better decision?

it will probably cost you a good $2500-$3000 depending on the parts you get. you would probably get between 35-45whp

which is good for the rs...it needs that kick!

agreed

thnx for agreein!
