Seriously I expect to lose some bottom end and slower spool but that is why the EFR is quite tempting.
With Fullrace telling me that an EFR 6758 is 53lbs/min and a GTX3071r only 2lbs/min more and then following on to say that it will spool faster than a TD05 it sounds too good to be true.
The big question is will 53lbs/min provide enough flow for 300+kw ATW?
See email below from Fullrace
Are you able to give me some advice on sizing for an BW EFR.
I have a Subaru Legacy GTB with a Cosworth CS600x long motor (2.65L, 272 Cams etc)
I currently run a stock location Blouch TD05-18G XT.
I am looking for more power while trying to retain a much low end spool as possible.
Is the 67/58 0.64 the correct size?
Does a 7163 fit in the stock location?
I have attached a dyno of the car currently and I would like to gain 50kw at the wheels.

Hey Shane,
That turbo is between 43-47 lbs per minute. The EFR 6758 will be 53lbs per minute, but will spool faster. The 7163 will fit in the stock location but we are still months out on having them in stock.
The EFR 6758 would get you the gains you want and the spool as well.
