Hey, I hope to be picking up my EVO this weekend, and have some questions:

Is there any way to solve the boost taper from 19 to 16 besides porting the turbo.

What is everyones favorite exhaust? What is the loudest/nicest/best flowing?

If I were to get an MBC what is the highest I could set it at on the stock turbo?

Thanks, this is a picture of my WRX I will be trading in :

 

nice WRX

nw to answear your ? :

1) no need to port the turbo, all you need is a boost controller to hold the boost all the way to redline.

2) exahust is a personal prefference and it is really up to you. some good companys that people seems happy with so far are:

Vishnu, HKS, JIC (although some had problems with it), BR, AMS, Perrin, RMR and Ultimate Racing. for pics of all of the exahusts that are out there , check out this thread:

3) i think you should be fine with 20-21 psi but just to be on the safe side, i would talk to some of the great tuners we have on this board and see what they think.


good luck with your new car and enjoy.

drive safe!!!!

 

Thanks Blonde.

I also have a Perrin oil catch can from my WRX as you can see there, It came with the red hoses and 2 little black connector type things. Can I use that on the EVO or will I need additional parts?

I also have a Walbro Fuel Pump 255 LPH, will this work too?

I was looking at the Buschar and APS exhaust. I know a lot about the cat backs already but do not know of companies that make just a catless downpipe.

 

Wow, that flat 4 looks complicated. :P

 

Mili,

The catchcan and the fuel pump will both work on the evo. Nice wrx, by the way.

Buscher is by far the loudest, but I think the B&B turboback has the nicest sound and one of the quietest. The Perrin is also very nice sounding and constructed beautifuly. Buscher has the best flowing exhaust also, as far as I know.

I use 94 octane pump gas and keep my HKS EVC 5 at 20-21. It's all about the octane.

"Is there any way to solve the boost taper from 19 to 16 besides porting the turbo."

Besides a MBC or an EBC, you could have your ECU reflashed by Alfried with Dynoflash, works, or a few other tuners. Shiv's XEDE or AMS EMS can also be programmed and configured to boost control.

 

Thanks for all your help.

I think I will either go Buschar, APS for exhaust.

Ill install my oil catch can the day I get the car. Then would like to get :

Exhaust.
Gauges.
MBC.
Wheels/Coilovers.
ECU reflash.
AFC.

Etc, etc.
