I'm like neck-deep in the build now, so it's probably too late to turn around, but curious what you guys think. I got them super cheap so couldn't pass them up, so this is my life now. I'd like to check out this build. There's gonna be some sick parts to support these little guys. Do you have a build thread somewhere?

Let me throw a thread together some time this week and I'll let you know.

Full-Race Geoff Posted August 12, 2017 Share Posted August 12, 2017 (edited) Ok - I prefer to see 3" as the smallest diameter for the inlet. edit: the 2.5" will work fine, but 3" can better avoid any surge with 7163s Edited August 12, 2017 by Full-Race Geoff Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/46/#findComment-7844212 Share on other sites More sharing options...

Full-Race Geoff Posted August 14, 2017 Share Posted August 14, 2017 ok good - 6758 is not nearly as sensitive to the surge margin as 7163. just something simple to keep in mind since its just a 90 degree bend and a filter on the end Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/46/#findComment-7844489 Share on other sites More sharing options...
iruvyouskyrine Posted August 15, 2017 Share Posted August 15, 2017 On 26/02/2017 at 8:32 PM, Meathead said: I'm using the turbosmart twin port actuator (14psi springs 3 turns preload) with 5.4w 4 port Mac valve @20Hz max d.c 60% for 1.6 bar boost @3800rpm. High and Low 3d boost maps on Link G4+ Had the EFR high boost canister but it is hopeless for good control and used to severely over-boost after 20 mins driving when WOT. It was about 20mm away from #1 runner so I extended the turbosmart actuator 50mm forward. Boost control is damn near perfect. @Meathead did you have to cut some more thread on the arm of the turbosmart actuator? My IWG actuator hits on the body of the car and was thinking extending it in this fashion would work almost perfectly i think.

Meathead Posted August 15, 2017 Share Posted August 15, 2017 Actually I cut some more off leaving around 30mm of thread and added an extension which I turned up to cover the spacer width.

sneakey pete Posted August 18, 2017 Share Posted August 18, 2017 Hope so, mine just left Austin... The 'Inconel' brand stuff kinda lost me at them trying to make it out like the inconel was what makes it insulate, and not that the inconcel is just the high temp protecting casing for whatever they use inside for insulation. And also the prices Link to comment https://www.sau.com.au/forums/topic/466636-borg-warner-efr-series-turbos-v-20/page/46/#findComment-7845361 Share on other sites More sharing options...
Piggaz Posted August 18, 2017 Author Share Posted August 18, 2017 Buraz' car. Went from a Precision 6262/0.84 to a 9180/1.05 on his Racepace built 2.8L. "target boost" was the same RPM - 4700 RPM, however the 9180 feels much stronger sub 3500 RPM. (Yes, the bigger turbo with the bigger ass end felt stronger down low). That falls in line with a couple other 2.8/9180 results that have come through lately. 6262 made 430 rwkw at 24 psi 9180 made 483 rwkw at 24 psi and 498 rwkw at 27 psi so possibly needs a larger exhaust. It's only a 3.5 inch RP item. * Adnan loves to rape this thing so the tune is softer than most. Once again, the transient response is the stand out. The stuff that can't be shown on the dyno.
