I have referred many new evo owners to this sticky to save a my voice; thank you! lol

 

Thanks for the list!

 

Bump great info thanks!

 

Got an 03 evo and not to sure what I should buy it. Just got it a month ago and it has the following

-injen intake and charge pipe
-hmbc boost controler
-custom turbo back exhaust with cat delete
-aftermarket clutch

Now I think the boost is set to around 17 psi.
I'm pretty new so tell me anything

 

Coilovers?

 

I've got it on springs

 

Do you know the history of the car? Is it tuned? I recommend a good wideband.

 

That's the thing. The people I got it from doesn't know much. So I have no idea

 

Break out the pocket book kid...Get cams, intercooler, injectors, fuel pump, and tune it for ethanol..lol It depends on what you are trying to do with the car. Unlimited options out there. What are your plans?

 

If your not sure if the car has a tune or not, you should definitely look into getting a tune first.

 

boost, wideband and oil pressure gauges.

Do you have a boost gauge and a wideband gauge? As of right now I would recommend doing general maintenance to the car because you really don't know how long it's been since the fluids and all that have been changed.

You can also bring it to a local evo shop and ask their opinion on what they think you should do.

How much power do you want out of the car? Are you going to race it at the strip? Autocross? Road course? Daily driven?

 

maintenance is the timming belt done , plugs wires boost leak test, fluids trans diff transfer case. Then check compression test, and then a good tune if all is well

 

As already said get a wideband and oil pressure etc and chexk your idle afrs and wot afrs and get a tune!

 

Why you guys tell op to get oil pressure gauge?his engine is not build,he's not pushing 500hp.
