Advice going forwards - Turbo Options?
To avoid clogging up either my build thread or the warning about CRV/BOV I sent out I figured I would ask this separately:
As you may know I had some bad luck and broke another set of twins (BRAND NEW < 1,000km on them). My build seems to be doing a great job of spiraling out of control cost wise (which sucks - I am not rich, I just saved really hard for this car).
I do not want cheap out on this build, but would like to try to make a smart choice going forwards.
Therefore, I would like to ask you all, what would you do in my situation? Please vote and send me your comments. I am open to all advice and suggestions.
I am quite interested about peoples thoughts on whats best for driving as well as future value - what is more desirable?
1) Rebuild the twins and just bolt them back on = <$1,000?
OR:
2) Sell the twins as is (damaged) or pay to get them professionally rebuilt and sell along with other unneeded parts (y pipe, crossover pipe, HKS intakes, FEED downpipe etc) and then:
A) Go Single (EFR 7670) = ~ $5,000 (need to fabricate an intake pipe, plus cost of a tune)
B) Upgrade to the SP twins = ~ $3,200 (plus cost of a tune)
C) Upgrade to BNR’s = ~ $2,500 (plus cost of a tune)
For the other category (in anticipation of suggesting a larger turbo) bear in mind I do not race, and I am seeking fast acceleration and a wide power band for fun driving through mountains and around corners. High HP is not a priority, I want FUN!
Thanks in advance, Tom

After reading your build thread and seeing how things have gone, I would rebuild the twins. Just to save money and get the car driving again.
Ultimately it depends on your end goal. If you planned to go single anyway this turbo rebuild could be seen as a waste.

Why not just get a used pair of stock twins , use whatever is reusable from your broken new set , port the Wastegate and that’s it really , tune not really mandatory and it will cost you less than 400$ CAD if you do the work yourself.
In theory you should survive with these turbos till you get all the parts for the single swap , the list adds up pretty quick.
once ready, swap and sell your twins stuff.

You don't say what twins you had.....and can't see the detail stamped on the compressor housing on the other thread.
A simple wheel swap and balance would be a no-brainer to me, assuming they're not something late with the different sizes. I'd expect several on here have 255/265 cores here with a good compressor section if none of the rebuilders have any, I know I have a few - you might need a new housing too with a bit of stainless steel going through the thing. 280hp ones might be more difficult?
I'm not sure if it's the retailers or Hitachi labelling stuff "SP" over there, but the original version is different - pity about the bloke you'd have to deal with though if you wanted the new approximation!
Even there, a single conversion isn't going to run just 5k despite any wishful thinking.

NM, I just saw the other thread. Rebuild your twins and move on. Keep the car on the road. Single builds take money and a long time, whether you do it yourself or pay a shop. There I always something that comes up during the build and slows you down. I personally wouldn't even consider anything other than an efr if you're swapping away from the stock twins.

Definitely rebuild. With them being so close to new they literally just need a replacement compressor wheel. That will be very reasonable to fix.
Is it both turbos or just the primary that was damaged? If it's just one, you could remove just that turbo to send to BNR for repair. But it may be worth sending everything so they can go through it and make sure it's in good shape.
I would call BNR and discuss this, I think this is something they can take care of for a reasonable price and turn around very quickly.

I came in here to say exactly this.^
BNR has been going through these turbos for over a decade, I think a wheel swap, balance, and a check up from BNR will be cheaper than you might think.

Regarding your comment on the single conversion costing me more that $5k, seeing as I already have a Power FC, larger primary injectors, v mount, meth injection, bigger fuel pump, standalone boost controller, wide band 02 and huge exhaust; what am i missing besides a kit from Turblown or IRP and a tune?
So tempting

Often find there's always nickle and dime stuff, don't know how comprehensive the kits are, but coolant lines for turbo (and wastegates if ewg) fittings for the water pump housing...not keen on push on hoses there, heat shielding for hoses, manifolding (brakes if rhd), oil feeds and returns, blanking plates, intake/airbox rather than bunging a filter on the turbo which is the usual expedient if not very smart thing to do, plumbing oil injectors back rather than have them spew oil on top of the engine when, rather than if they fail assuming you're keeping them.....topically, a bov maybe, lol! There's a myriad of items undoubtedly overlooked too, but that's just some of the stuff I had to make.If the primaries are 850s, I'd ditch those, not much of a fan of the PFC either, wastespark and all. ECU here picked up a defective fpr via pressure monitoring, which you'd need something else to cover with the apexi. I'd like egt info as well.
