Hi folks from Canada's East Coast! I have a 99 B4 EJ208 TT that I've been tinkering on for past 9 years and I'm having an issue with my secondary turbo leaking oil out both ends into compressor snail and downpipe/ECV. 2nd turbo is a VF26 CHRA with VF27 exhaust and compressor housings, so it's journal bearing type. The banjo bolt is identical to the one in the primary VF26 turbo, so oil flow should be the same. No restrictors that I've seen, but I've heard they're usually in line for the VF27 BB turbos. The stock VF27 was leaking oil too before swapping it out for the VF26 CHRA. Both turbos have fresh rebuild kits with primary being completely dry, yet 2nd leaks like mad. I'm almost positive the ECV is collecting oil because I get a bit plume of blue gray smoke when I spool 2nd turbo and the up pipe is oil soaked (maybe coming out through the ECV flap linkage. My current thought is over pressure inside the turbo CHRA which is pushing oil out through the seals (small piston ring type). Cause is either too much oil flow or poor drainage. I have a dual oil catch can setup that I've confirmed has good flow out of the crankcase and head breathers. And I'm positive I haven't overfilled the oil pan so it shouldn't be an issue of oil not draining due to crankcase gases flowing up the drain line. For oil supply, there is no restrictor, which I think is proper for a journal bearing turbo. Mind you the stock VF27 didn't have a restrictor either. Kinda stumped on why its leaking. Anyone have any advice? Related Mod List: Killer B oil pickup and windage tray Ebay Silicon TT inlet DIY dual oil catch can setup (PCV valve clean and floating proper)

I need some advice on whether it would be okay and whether my engine will work properly if I was to install a BOV. Would I need a BOV with an adjustable vent to atmosphere and recirculation? Would I need to have it on 50:50? What BOV would be recommended? Cheers. Also I own a 2001 Twin turbo Subaru legacy automatic.

Hey Fellas so still pretty new new to the subi scene with my first subi being a 02 BE5 REV D Legacy Twin Turbo. So the problem I’ve got is I want to get a bit more power out of it especially in the mid rev range where boost drops off. First off I’m trying to find a zerosports sequential controller as I’ve found that it will fix my problem but I’ve also herd there are some electronic Boost controllers out there where you can set the boost through certain rev ranges. I just have no idea which EBC’s do that and or what EBC will be the best for my car. So so just looking to see what other B4 TT owners have done mod wise to gain more power or help with the boost ranges. thanks guys look forward to some reply’s

Hi all. Because dumb question thread seems to have gone will ask here. I have a fair bit of smoke coming out of bonnet scoop after a bit of hard driving. There are no oil spots on my drive, no signs of leakage anywhere and oil level isn't dropping at all. Seems from what I've looked at that it's not coming from the turbos but more from under the intercooler. Only other thing to add is I think I may have a little too much oil in the car atm. Thanks guys
