Great read so far, keep the updates coming!

Me again, here are some pictures comparing a 7064 to a 7163. The space gained from the 7163 will probably be used up by the v-band to t3 adaptor. Another option would be to slightly tilt the engine. Anyone got any experience with that?

Well, space is tight but not tight enough for welding something on a new 2000$ turbo

Dynosheet: http://www11.pic-upload.de/24.10.14/jqwwwwooo3j.jpg Specs: - engine stock - 3" downpipe - Blitz Nür Spec - K&N pod filter - FMIC - Nistune - stock manifold - tuned to 1.3 bar (= 18.85 psi), falling to 1.15 (= 16.68) in the higher revs due to the used boost controller Same car (= not mine) from the pictures I posted.

Like I said - the pictures are from a friends car. I do have a bit of time before my engine comes back from the engine builder and I have to make the decision. Thanks for the machining tip though Will do (probably around April).

I recently bought a 7064 and my tuner is struggling a bit to get it fitted into my engine bay. Car is a R34 GTT with stock manifold. Problem is the exhaust housing (almost) hitting the strut tower. Will the 7163 with a T3 to Vband adaptor really be a better fit? I couldn't find any dimensions for the exhaust housing of the 7064 and 7163 aside the BW catalogue pages: http://www.fin-turbo.fi/uploads/files/EFR7064_1.pdf http://www.3k-warner.de/files/pdf/BWTS_2014_Performance_Turbo_Catalog.pdf (page 19) Attached some pics of a friends R34 GTT with a 7670 fitted on the stock manifold. Very tight fit around the strut tower.

Have a look: http://blog.perrinperformance.com/borg-warner-efr-7163-test-and-tune/ It's on a Subaru STI.

Great thread and great read! Good luck being back in AUS

Finally finished with all of the 96 pages! Very interesting turbos that BW churned out. I'm currently in research mode for my next turbo to buy, because my R34 GTT needs a new one. The one thing I hoped to get answered from this thread: Can you run the EFR turbos with an old ECU like an Apexi Power FC without fiddling around too much? My tuner hasn't got his hands on any EFR turbos yet and is a bit reluctant to first try one out in a customer car... He specifically stated that the EFR turbos were different compared to older turbos in boost control and/or waste gate control and the ECU would need input ports that the Power FC doesn't have. Can't find any reference to that in this thread nor through googling I do think he knows what he is talking about and has has got extended experience with Borg Warner turbos. The shops owners run 3x S366 on two Supras and a R34 TKR. Anyone care to clear this up?
