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

 

 

Do BNR's now and enjoy more power and turbo longevity. Stock twins just don't cut it for a car like yours IMO.

 

 

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.

Why do you keep going through twins? especially a new set...

 

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.

 

Thanks for the response! Yep, rebuilding the twins, especially with them having less than 1,000km on them is the first option I am looking into. Once I get a professional opinion on the damage and an idea of the price i can decide if its worth it.



Thanks for the response! I totally get where you are coming from, this car deserves the best....just need my bank account to keep up with it
Thanks for the response! Yep, this is for sure a very tempting option, that way I can use funds to finish the rear suspension as per my planned winter work! Regarding parts needed to support going single - 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?



Thanks for the response! Agreed, rebuild is a good option and is currently being looked into.

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


Thanks for the response! Yep, looking at the rebuild now. But i am tempted by those EFR turbos!


Thanks for the response! Just the rear is damaged. My hope is exactly what you said - that with the twins being so new the fix is hopefully easy.


Awesome, thanks!

 

Sounds like you have most of the big items, but guess you will be paying in CAD, which has seen better days like the pacific peso down here. 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.
