Subadozer Posted February 13, 2013 Share Posted February 13, 2013 At long last my shelf queen 16g is on the car. Took over-advance CEL's and discovery that the shaft on the turbo on the car was starting to loosen up (later discovered stuck-open wastegate) to motivate me to end the 2+ year procrastination. Now on to the tuning. Link to comment Share on other sites More sharing options...

Yes, its overkill but if its basically the same price, actually cheaper, why not just put them in? That was my thinking anyways.... Link to comment Share on other sites More sharing options...

fahr_side Posted February 15, 2013 Share Posted February 15, 2013 so people are actually running stock fueling on the 16g's? That seems crazy to me. Â Anyone have any insight on power/efficiency with a stock fueled 16g vs 650cc or 740cc and a pump? I have to image there is a noticeable difference... You will have to turn the boost down a tiny bit at the very top-end with stock fuel, but it's only past 6k you'll notice this. With just an STi pump I can run 16.5psi at redline and keep to 11:1 AFR on the coldest days. Yes, I'm at 96 or 97% IDC but with enough fuel pressure to back the injectors up and a WBO2 to confirm, this is quite safe. I can tell you that even with a very efficient intercooler it is not worth increasing boost to even 17psi as compressor efficiency is really dropping off there. If you have a stock pump you have to taper more as it can't hold line pressure steady at high revs / IDCs. You need a WBO2 to confirm your actual AFRs and you want to have a good MAF scaling. The easy way is to throw more money at it and get the injectors, but it isn't necessary and IMO not worth it.

ExRex01 Posted February 15, 2013 Share Posted February 15, 2013 Thanks again fahr_side. I have WB02 so can keep a close eye on things while driving and log the data also for MAF scaling with my tuner. Will be sure to carefully creep up to the top end with a few tune revisions. Long term plans are for larger injectors and E85 but not until I can afford to be replacing the OEM clutch! Link to comment Share on other sites More sharing options...
BigBopper Posted February 15, 2013 Share Posted February 15, 2013 I have finished the install of (Infamous') IP&T's Turbo Oil Supply Line Filter Kit on my '10 LGT w/BNR TD05H/20g. This kit was developed for the 4th Gens, so I had to change up a few things, from the standard kit, to adapt it to the 5th Gen turbo setup. I used (2) two 16" oil lines and made it work, along with some stainless bolts and silicone covered straps. Thought this might be helpful for anyone going down a similar path.

Let me know if I can assist in your turbocharger needs! Bryan@BNR 205 640 1193 www.BNRsupercars.com Bryan (or anyone else for that matter), have you seen high EGT's on the TD05-20g LGT setups? I ran a TD05-20g on my STi swapped time-trials WRX for a while years ago, and it was an incredible blend of low-lag and high output, but on long pulls I'd see 1800+F EGTs. During long track sessions, it was hot enough that stuff like the radiator fan housings and plastic timing covers on the motor were melting.  A friend of mine more recently ran the same turbo on his STi for autocross. Again, it was a great blend of spool and power, but the small-ish exhaust housing apparently lends to high EGTs... he eventually decided just to got back to stage 2 on his stock STi turbo due to the high temps and a fuel pump issue he no longer wanted to try to solve. At the time, we didn't realize that the EGTs were just a side effect of the particular turbo, but when my friend sent off his request for an E-tune to Clark Turner for a TD05-20g map, Clark's response was "whoa, that turbo is going to have high ETGs!". I'm wondering if the LGT style TD05-20g turbo will have the same temperature issues as the WRX/STi style turbo. A 20g is likely larger than I want for my outback, but knowing how "in the sweet spot" that turbo was for making early torque without giving up tons up top, I might consider it if doesn't exhibit the same EGT issues we noticed on the other cars.

fahr_side Posted February 16, 2013 Share Posted February 16, 2013 Depends on the exhaust housing. TD05H-20G really wants an 8cm2 housing on an EJ25*.

Even though not applicable to my situation I found your information interesting and I'm sure the 5th gen folks will find it very helpful. Link to comment Share on other sites More sharing options...

sperry Posted February 18, 2013 Share Posted February 18, 2013 Bryan requires that you use an aftermarket filtered oil line with all of his turbos in order for him to honor the warranty. Do the newer cars even have the same problems as the older cars with the turbo feed line clogging? Seems like a silly requirement if the 2010+ cars have a completely redesigned feed line, especially if there's no bolt on filtered feed line available yet in the aftermarket. Denying warranty coverage to someone who's unwilling or unable to reengineer the existing line kit to fit a newer car sounds a little harsh.

BigBopper Posted February 18, 2013 Share Posted February 18, 2013 Were you seeing oil starvation issues or something else which led you to upgrade the line or was this just for piece of mind? No starvation issues. Found some excessive radial end play in the turbo journal bearings after only 600 miles on the turbo, 500 were clutch break-in period (no flogging or boost), 100 were to/from and inclusive of my dyno tune session.  Sent turbo back to Bryan @ BNR for inspection, and he found the journal bearings had been contaminated and was the cause of the issue. Turbo has been returned to pristine fresh condition. So, to answer your question ... I had been debating about upgrading the turbo oil line and having an easily accessible inline turbo oil filter, so I took the opportunity to modify a kit that Mike S had developed for the 4th Gens, and made it work on the my 5th Gen, while I was putting things back together. Bryan (BNR) and Mike Sprank (Infamous) have recommended this type of oil line/filter configuration on turbo upgrades for years, especially for those customers that had suffered turbo failures.   Bryan requires that you use an aftermarket filtered oil line with all of his turbos in order for him to honor the warranty. ^ Bryan has seen his share of turbos that have met their demise over oil starvation and contamination issues ... it makes sense.  Sounds reasonable to me. Who else warranties aftermarket big turbos? ^ I agree... just good business practice. Link to comment Share on other sites More sharing options...

Either you're willing to make sure the component is operating in an optimal environment or you can deal with it when it if it goes boom.  Sounds reasonable to me. Who else warranties aftermarket big turbos? If I were in that business, I wouldn't warranty anything that requires the layman to engineer and fabricate an oil line filter kit based on adapting another kit. Either require a specific kit, warranty it anyway (because perhaps the newer cars don't have the oil starvation issues that the older cars have?), or say "sorry, no warranty until someone comes out with a good 2010+ line kit". I'd hate to see people that aren't comfortable or capable trying to build their own oil feed line just to get a warranty if the risk of screwing up the turbo because the line isn't right is higher than the risk of using the OEM line. Again, it comes back to the quality of the OEM line on the 2010s. I haven't been paying attention since I've got a 2009... but I haven't heard of the newer cars having turbo failures. In fact, I haven't heard of frequent issues since the switch to the vf46 in 2008, compared to the nightmare people have with the vf40s. Is the oil line really something people with newer cars should be concerned about? Sure, it's a good idea to have a nice high-flow serviceable in-line filter on any turbo... but is it as risky on the gen5 cars as it is on the gen4?

SurlyOldManMN Posted February 18, 2013 Share Posted February 18, 2013 You're right. It would make more sense for him to offer no warranty at all from a business perspective. Thankfully he is willing to offer irrational goodwill to customers. Nobody knows about risks for the 5th gen. Hardly any aftermarket turbos installed anywhere. I can count the ones I know of on one hand and still have enough fingers left over to get myself in trouble in a few different ways. Fewer still that have hit 100k+ on a stock turbo.
