No you don't need a catch can, you can put one for kicks and giggles but you'll get along fine without one

 

you dont need one but the more pressure in the engine, the more oil that will end up in the intake. Its always a good idea to have one. Mine is basically a air compressor filter inline to the intake. You can get everything from home depot racing for about $30

$14 for the filter
$12 for the fittings (1/4" to 1/2")
$6-10 for hose

BTW, those pics were in my gallery and got deleted for space

 

Would an EBC work just the same, or do you recommend using a MBC?

 

EBC's are the best. Go with an Apexi AVCR they have the most features and you will be able to get the most outof a stock turbo.

 

I don't mean this to sound offensive, but if this mod is so cheap and just as effective/safe/reliable as a chip....why are people still paying $500 to get their ecu flashed? I'm assuming most just don't know about this or don't trust it?

 

not everyone can use it, trust it, or install it. A chip is still the best way to make power and reliably. This is just a cheap thing to do until you go that route or bigger

 

So I guess what your really saying is if I got the $500 to spend I should go the chip/flash route unless I plan on going BT in the future.

 

this has few more limitations than a chip. it will not make as much power as a chip because you cannot alter your redline. Also (though some say you don't have to) you need to increase the amount of fuel you inject and advance your timming for best results. The reason people still pay for a chip is the same reason people still pay people to change there oil.

 

the power dies past 5500rpms. Why would you need to increase the revs past 6800? Your making about 30-40hp less there than 5500rpms.

 

do a little research on the early chrysler omni/daytona/laser cars. this was one of the first things you would do to the 2.2 turbos. MBC and a zener diode would drop minimum of a second in the quarter.
