Hey, I new to fourms and want to know more about Evos amd Mitsubishi in general. I'm selling my WRX soon to get one, so hope you guys don't flame on me too bad. Thanks

 

Don't worry about it. I didn't know much about turbocharged systems until I bought mine.

 

Thanks, yeah I very well rounded with turbo charged car but when i pick up a evo I want to know what parts to put on there and what not to put on there. For example for our subaru, MBC are a no. Stuff like that.

 

i like how you say OUR subaru but ianm12 doesnt have one. but yeah ive had a mbc on my wrx since i got it and had no problems. wtf? plz search before you start askin dumb noobie subie questions. stuff like that.

PS
welcome!

 

What I didn't even ask about putting a MBC on. In fact I did my research and WRX don't do very well with them. YOU CANNOT SAFELY RUN A MBC ON A 04-05-06 WRX.
THE ECU HAS A CLOSED/OPEN LOOP DELAY THAT WILL CAUSE YOU TO RUN IMMENSELY LEAN WHILE UNDER A GOOD AMOUNT OF BOOST. THIS WILL END UP IN YOU BREAKING PISTON RINGLANDS (IN OTHER WORDS BLOWING YOUR MOTOR) THE 02-03 WRX'S DO NOT HAVE THIS PROBLEM, WHICH IS WHY THEY CAN SAFELY RUN AN MBC. YOU HAVE AN 05, YOU CANNOT RAISE THE BOOST SAFELY WITHOUT REAL ENGINE MANAGEMENT. IN FACT, YOU CANNOT EVEN RUN STOCK BOOST, OR LESS THAN STOCK BOOST, WITH A MANUAL BOOST CONTOLLER. YOU CANNOT SAFELY RUN AN MBC AT ALL ON AN 04-05-06 WRX. So you ****ing do your research.

 

Boost Controllers: Manual or electronic, both can cause serious problems. With the stock boost control system, the car only gives you full boost at full throttle (which is over like 76% or something... ish). With an aftermarket boost controller, you'll get full boost whenever the turbo is capable of it, which includes partial throttle times from like 15% throttle on up. You do a lot of daily driving and highway driving in this range. The problem is with the ECU once again. At partial throttle the car usually sees 7 to 10 psi, or about wastegate pressure. It injects only enough fuel for 7-10 psi. When you pop a boost controller on there it just assumes you're still getting 7-10 psi, but you're getting full boost, which is probably 14.5 to 16.5 depending on where you set it. So you've got the fuel for 7-10 psi but 14.5-16.5 psi of boost! This causes an extremely lean condition because of all that extra air without any extra fuel, EGT's (exhaust gas temperatures) shoot through the roof, and soon a piston melts. stuff like that
