so are they all the same? and are they pretty much universal? i mean im looking around for one for my brother and they all say/look the same as lets say the rx7store ones. was thinking about getting the megan racing one for like 50.00 which looks almost exacly like the old style greddy

 

Don't get your brother knockoff junk for Christmas

I'll AIM you later, I'm sure I can find ya a nice one for a decent price (and cheaper than a Tial WG too)

 

HMM, great question.

im pretty sure they all have the same function, but i can put some cash on it that they all wont work the same. some designs are more efficient than others.
but like you said the megan does look very similar to the greddy ones.

can any one elaborate, im curious now.

 

i think more along people with 240s/silvias have something like this in their car,

 

All the catch can does is it...... catches oil in the can

You can either run a line from your oil filler neck to the can, and smack a breather filter on the second nipple of the can to de-pressurize your oiling system, or you forego the breather filter and run the second catchcan line over to the compressor inlet (between the air filter and turbo charger). This is the way the factory has it hooked up.

With stock twin turbo cars there's usually no need, unless you're doing some serious road racing.
