HarrisRacing Posted February 1, 2016 Share Posted February 1, 2016 Overrated mate save your money. Your response looks better than an 8374 for sure. I have never seen a convincing dyno chart for and rb26 or 28 yet even though these things have been out forever. Will be interesting to see piggazis and Harrisracings when they eventually post a chart. Sorry for the delays in my project, but I'm back on it and set my goals to have that thing dyno'd within 45 days. I'm trying like hell! Trust me, I want to see an 8374 efr dyno on a stroker as well Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/116/#findComment-7676141 Share on other sites More sharing options...

MaximuSmurf Posted February 4, 2016 Share Posted February 4, 2016 Anyone running one of the newer T4 TS 6758's on an SR20? Can't find tooooo many people around with the setup. Thinking about going low mount T4 TS manifold and 6758 T4 TS 0.80 turbo (stiffer spring on internal wastegate) on my S15. It's daily driver. Some weekend warrior, and occasional track day. I'm all about that response. Poncam, Z32, 2000cc injectors, Forged engine, RB25 gearbox, Nistune (e85 Fuel).... was hoping for 300rwkw, maybe full boost around 3500rpm. Which seems to be a fantastic package, especially with that off boost and 'transient' response the BW are known for. Can anyone speculate on results of the TS 6758?? I know everyone totes the 7163, and I do love it, was considering in T4 TS version... however I just think I'll end up netting ~350rwkw which I just don't think is useable in an s-chassis. "slow is smooth and smooth is fast" - some guy probs a while back.

MaximuSmurf Posted February 4, 2016 Share Posted February 4, 2016 Oh also, has anyone seen these new BW 90 degress housings? Seems like would make pipe layout on an SR20det (S15 in my case) alot easier.

MaximuSmurf Posted February 4, 2016 Share Posted February 4, 2016 That front housing is a brilliant idea. Yeah I've emailed GCG to see if they can get it in. Will try Fullrace in USA if they can't.

Piggaz Posted February 4, 2016 Share Posted February 4, 2016 I can't find them anywhere online. Can you purchase one to suit an 8374?

HarrisRacing Posted February 4, 2016 Share Posted February 4, 2016 Agreed that housing is more compact in everyway. My boost solenoid (8374) is out on the edge of the compressor housing as well. While mine fit well like it is, I bet the 90 degree is a better fit with piping.

MaximuSmurf Posted February 4, 2016 Share Posted February 4, 2016 Gcg got back to me and said they can get them in for the 6758. Not sure on other sizes. They don't carry them as they're brand new and don't have any on order yet. But maybe email them if anyone is interested in converting over.

MaximuSmurf Posted February 5, 2016 Share Posted February 5, 2016 Another update. GCG just advised they won't be getting those compressor housing till at LEAST May this year. I'm not in a rush but just an FYI in case anyone else was keen.

Full-Race Geoff Posted February 5, 2016 Share Posted February 5, 2016 these new BW 90 degress housings? Seems like would make pipe layout on an SR20det (S15 in my case) alot easier. agreed- for SR20 s-chassis that 90 degree housing B1 turbo posted above can help clean up pipe routings. They are much more expensive housings however for the bigger 8374 and 9180 turbos, these already come with an optional vband you can add a 90 Anyone running one of the newer T4 TS 6758's on an SR20? Can't find tooooo many people around with the setup. Thinking about going low mount T4 TS manifold and 6758 T4 TS 0.80 turbo (stiffer spring on internal wastegate) on my S15. It's daily driver.

Which seems to be a fantastic package, especially with that off boost and 'transient' response the BW are known for. Can anyone speculate on results of the TS 6758?? I have not tried the TS6758 but I agree it may be a perfect combination for what youre considering. You can use it with the 90 degree housing I have a beater S14 with SR20 and was running an old 6258. it works so well on a junk setup for 350hp that i dont plan to change anything Holy smokes is that really 630 whp on PUMP GAS?! Well I'm hoping to hit my target of 550 whp on pump gas. yes that is pump gas, on a built/prepped RB30. 550whp seems reasonable if the wastegate actuator is properly sprung and everything is in order. Geoff, does full race have these in stock? We stock the entire line of EFR turbos, the 90 degree comp covers are en route to us AFAIK, They've only released the 90° housings for the 6258, 6758 and 7163... 100% correct. 8374/9180 already have a vband outlet that can serve as a 90 addition easily Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/116/#findComment-7678924 Share on other sites More sharing options...
HarrisRacing Posted February 7, 2016 Share Posted February 7, 2016 Can't believe I have this turbo and didn't notice that? Do you simply machine off the end and then use a 2.5" vband? Does someone sell a 90 with flanged connection already? I'd really interested. My piping does fit well but it is all silicone. That outlet really gets tight near my shock tower. 1 Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/116/#findComment-7679800 Share on other sites More sharing options...

Full-Race Geoff Posted February 9, 2016 Share Posted February 9, 2016 yes that is correct @harrisracing -- cut the end off and its a standard vband. the same as any Cummins/Holset turbo and many other BW or MHI turbos. There are cast 90 degree vbands available for this application but you could also just but a vband and weld the intercooler pipe to it Link to comment https://www.sau.com.au/forums/topic/341890-closed-borg-warner-efr-series-turbos/page/116/#findComment-7681095 Share on other sites More sharing options...
