2003 Lancer OZ Rally Upgrade Suggestions
 

Hey guys I have a 03 OZ rally (automatic transmission :thumbdown) recently got it about a month ago. I was wondering if any of you guys could make some suggestions on upgrading my OZ. Which would be the best 'cold air intake' 'exhaust' etc. I wish I had a 5 speed but this is what I have and what I can work with. Thanks.

Welcome to the forum, try searching on google with "evolutionm.net" to search around the forum quickly. There are many threads on this very subject.

There is no upgrade besides a turbo that is going to give you real power gain on the 4g94 :/ This is why most of us went the turbo way...although if you dont want to spend the 2k+ going turbo a couple bolt ons is always fun for the sound!

Thanks
 

Thanks for the replies. So going turbo is the best thing to do? I would have to build my own kit correct?

Exactly...there is plenty of threads on how to turbo your lancer! You can search whatever you like on google and write evolutionm at the end and you will find what you are looking for. Good luck u can always pm if u need help

Just got a 03 oz where should I start for building the motor

To build the motor? Honestly no where man.

pistons & rods, wisecos and k1 from speedcorps.com. Currently burning oil, but i think im using too low of a viscousity. Going to run 20w50 since i have a suggested clearance of .0035 PTW.

Corndog did you have to notch your block for the k1s?

What kind of turbo should I go with for a stock oz 03 five speed and what kind of ecu I want 300 + whp..

You won't have 300+ hp with a stock bottom end engine...you can search a little more in the forum there is plenty of turbo threads.... here's 2 of them:
This one uses evo 8-9 eom parts

This one uses evo 8-9 aftermarket parts

Good luck.

Some cheap and relatively easy options would be a CAI, a decent header, and a nice exhaust with a sound you'd like. If those basic power options aren't suiting your fancy; consider a piggyback for your ECU to get the most out of those upgrades and your basic engine.

No, no need to notch the block. Cranks no problem.

hey guys
 

i need some help im in tampa fl i was on tge highway and my clutch is going all the way down with no pressure and popping back up there was also fluids leaking under the motor some told me it could be the slave cylinder or master cylinder anyine around who could take a look or suggestions..

Hoping I don't offend any other Lancer owners out there, but if you really want more power, keep the 2 grand you'd need for a custom turbo install and use that towards a car with a bigger motor.
