I am done modding my MR and like to share my experience

I've tuned the car with the intake and it runs great at WOT, just getting the same trouble others get when using the RS intake. The idle is not steady. It keeps hunting or surging.

have you got the car dyno'd?? i'd be interesting in seeing what numbers it made.. considering those are pretty much the same mods i have... HKS RS kit, 3inch turbo back exhaust, walbro fuel pump, boost controller @ 21-22lbs, and of course dynoflash.
my '03 evo makes 291 whp with that

1. HKS RS Instake - Easy 1 hour Installation, but the motor will run like sh*t if you don't retune the ECU. I was somewhat disappointed with this intake though, because it doesn't really fit right. The bracket provided will not fit. I have to rest the yellow mushroom filter on the frame. And the filter/MAF sensor silicone tubing is bent slight upward. I don't think it will decrease performance, but HKS should have done more test fitting to ensure it will fit correctly in a USDM evo. One thing I really like though is the loud "psssssssh" sound from my stock BOV.

Thanks for all the inputs guys!
I will definitely try to redo my RS intake to see if if the mushroom filter can rest on the bracket. If possible, can someone please post the underside of the filter so I can see how the bracket and filter are sitting?
I ended up with the HKS EVC V instead of the Hallman MBC. The installation is quite easy after figuring out our evo has the internal wastegate setup. One small flaw with the EVC is it didn't come with vacuum hose size reducing adaptors. Our car has 4mm nozzles on both the turbo outlet and wastegate, but the HKS uses 6mm hose on the boost control solenoid. So I picked up some adaptors from pepboys to finish the job.
I also got Kartboy polyurethane exhaust hangars today to see if i can eliminate the rattling noise.
Al from dynoflash told me that my car should net around 300whp with 91 octane or 320whp with 93 octane, but I plan to dyno it soon. Anyone know where to dyno an EVO in So Cal?
Actually, I really meant to say I am done modding my MR in the engine/power area. I am pretty happy with the power and handling of the car. I just don't want to risk taking apart the motor to do cams/cam gears, bigger fuel injectors or messing with a bigger turbo. I still want to do simple mod like turbo timer, radio upgrade, and HKS SSQV, etc... Any other mods you guys recommend?

I've used Harman Motive (www.harmanmotive.com) in Torrance. They have an AWD Dynojet.
that was very organized. I heard Al from Dynoflash saying that the ES hallman MBC wont hold more than 15psi.
I think you may want to reconsider before you do all the work to install that.

Very nice write up. My MR is similar to yours, in terms of upgrade path. What you said about the RS intake also happened to me, in fact, the whole kit is slightly too long that the filter was hitting the tramission fluid bottle. Had to cut .5" off the pipe to get it fit perfectly. I'm using the HKS downpipe which fits perfectly, and so are the UR 2.5" test pipe & HKS Cf-Ti catback. For intercooler piping, I chose RMR's, which wasn't hard to install, perfect fit, but does require a bit of patience. I'm getting my car dynoed & tuned at TT on Thursday, I will post results that night on how things are.
