im sorry. the muffler tip is 3.5. the inlet is 2.5

 

2.25

 

You are 100% RIGHT. he will lose a ton of power. Stay at 2.25 inch max, N/A or Turboed.

ROAD/RACE

 

so no high flow cat then?

 

i don't think it will be beneficial for a naturally aspirated engine...

 

thank you. but id like to get more power. already looking into a cai. anything else beneficial?

 

the best intake mod you can do is RalliartN's intake mod, with like a K&N filter in the stock air box...the cost is minimal, and the plastic won't absorb heat like aluminum piping will...

as far as exhaust, go 2.25" max, and a free flowing muffler. Next i would go with a urethane engine roll stopper, and a tune. Bolt on mods will not give you huge gains, tuning will allow you to take better advantage of bolt on mods, but for dollar:horsepower ratio for bolt on mods is the shyts...in my opinion if you want any noticeable power gains you'd be better off boosting it, but that's also expensive, and a whole other can of worms...

It's a fairly powerful little car anyways, i recommend engine mounts, shift bushings, and coil springs, and sway bar...make the car drive and handle better, then worry about what route you want to take for power.

 

thanks for the advice. im just starting to upgrade from stock parts and i really had no idea what to do.

 

i need o2 sensors by saturday so i cant have them shipped. do the es model's or oz model's have the same o2?

 

so i'm thinking all i need is the k&n air filter for a starter intake mod? that's pretty neat

 

with the air box drawing air from down low, and also drawing air from more than just the stock locationg you'll pick up more dirtn so you'd be replacing your filter more oftem, but K&N's can be cleaned. They say they flow better than stock, but then which manufacturer are they referring to, when they make that claim.

 

I used this but I think there should be something in here telling all noobs like myself that there are better ways to get parts that are cheaper and maybe a little list of things that are good deals or something you know? just a thought.. I know that I did check this thread out first and then went and bought a few things that I wish I would of looked around more for.

 

I've read and searched and red and searched some more and I haven't seen any ?'s or comments addressing whether or not a stock/OEM OZ rally rear spoiler will fit on an RA. I'm talking about the one with the pillar underneath the third brake light.

Also, I was wondering if the harness for the brake light is compatible with the one on the RA or would I have to splice and dice?

 

It will fit, but I'm not 100% about the light connection. I would think it would plug and play though. Do a search on the oz spoiler maybe you will find a picture of the plug to compare

Or ask Cranswick to check it out , he has an OZ and a Ralliart

 

negative, my 03 is an ES wingless, soon to have OZ body kit, the wife didn't want the wing, but you are correct the dimensions will fit, but i can't confirm the electrical connection...
