i have put in a TDO6 25G turbo with 4" inlet in my 95 sti, now its in what happens to the breather pipes that went to the bent flexi induction pipe from the old turbo,

they went to:

1, the valve under the throttle body housing
2, both heads top breather pipes
3, the thing with A,B,C on, on the back right of the inlet manifold (sorry i dont know the proper name for it)

any help would be appreciated, cheers phil.

 

Oil catch tank.

 

i have a catch tank to put in and was wondering which would go to it, but what about the one on the right of the inlet manifond with A,B,C on the top of it.

 

The two head breathers and the crank breather go to the can, blank the pcv at the same time.
The othe hose you mention goes to the idle control sol, and needs plumbing into the intake somehow.

thanks for that, which one is the pcv pipe? is it the one that went to the turbo housing, and is the idle control solenoid the thing with A,B,C on it, sorry for being a bit of a div but im just making sure.

 

If you look at this pic of my engine, (click on pic!) i replaced the turbo intake elbow with a blue silicon one. The 3 positions i've circled in green are the head and crank breathers, whitch all go to the intake elbow via plastic pipes. The head i've put small filters on,(yours to the catch tank) but you can't see them. The crank breather has a 'T' in it, and goes to the inlet elbow, and to the pcv on the manifold under the trottle body, where the yellow circle is.I blocked it at the manifold, but you can block it at the 'T' on the block instead, and vented the crank to atmosphere.( yours to the catch tank)
The 2 white circles are the idle valve pipe work, and need to be kept. I take it you've ditched the standard air box?

It was easy for me as i had the inlet manifold off for the parallel fuel rails, paint, inlet insulators etc, and ditched all the plastic breather pipework when it was off.

Where did you get that blue silicon turbo intake elbow from??

Just replaced my turbo and wondered to plumb that in made my own up but slight leaking making it run off!

do you have to keep that black box bit in? (between the MAF and turbo)

 

Hi, i got the elbow off ebay. Theres a few companies on there that do various sizes.
I kept the black resonator box as the idle control valve pipe goes to it, i also plumbed my dv to it as i wanted to keep the recirc type.
The boost sol also vents to it, but this can be left to atmosphere.

 

thanks for all the trouble you have gone to, yes i have ditched the air box and everything, i wont be putting the filter back on or the air flow meter as i have a apexi pfc to go on, so what to do with the idle valve pipe work, phil.

 

You can delete the 2nd resonator with this:-




Appears to have all the various breather ports on it. Get it from:-

MRT Performance - PLENUM STL REPL SILNCR WRX 94-96+RS

 

That looks interesting, i wonder if it really makes any difference as they say

 

Obviously, it would be best if a tweak was made to the map to cater for the fact that it's freer flowing... but you probably wouldn't notice the difference on the road (Bet it makes a good noise though ).
