I got my new BW 7670 EFR today and i'm gutted the build quality has plummeted the exhaust housings are shocking looks likes Stevie Wonders been in there with an angle grinder then Ray Charles did the QC inspection.
It doesn't even sport the Borg Warner name anymore suppose they are too ashamed to put their name to it.
The Compressor housing isn't much better roughly finished and machined.
I know some people will say it doesn't matter how it looks but how it performs that counts but when you're paying the kind of money these cost you don't expect this kind of finish.
If it hadn't come in a sealed box from a reputable company i'd of said it was a chinese knock off.
Here's a video walk around of it:
(Oh ye and sorry for the heavy breathing i've got a dodgy knee and now systematically make loud breathing noises as I move lol)

That is terrible, I'd be onto who I bought it off asking questions

mk2grp1

look on the Brightside you have a brand new turbo and it didn`t drop on your toe during the walkaround

Mark Shead

LOL go buy a pretty turbo then, If not about the outside its about how it performs,
You wont be saying its crap when you try it LOL.

Mark

dojj

iTrader: (3)

it probably looked that way after you dropped it on the table 50 times trying to video how bad it looked

tis a big old lump though

ajamesc

Don't go look in dafs wear house full of fooked turbos and engines with bent con rods then lol or you really will be shocked!!
On the daf mx engine they suffered from roller bearing brake up letting all the oil go in the inlet causing them to hydraulic lock.
Daf were taking them to court the bill is meant to be for millions!

I'll still be fitting one to mine as they did iron out the problem in the end

I knew you'd say that Mark, but you've gotta agree the finish is truely terrible they have certainly let their standards slip?
If they are prepared to let the outside look like this what's to say they haven't lowered the standard of the internals too?

its absolutely unacceptable and there is no excuse imo, its the quality expected from a cheap Chinese knock off not a high end top of the range turbo !
all the garrets ive had all were finished well, and the twin billet gt30s on my 3.8 have insane response boosting hard by 3000 rpm.


I look forward to your views on it rich in comparison to your old gt turbo, is your current gt35iirc turbo billet or non billet ?

I don't mean any disrespect to you Rich and i don't know the full cost of these so forgive me, but surely it's how it will perform rather than a fashion show?? As said, not a dig at you as i understand where you're coming from. Surely once fitted & mapped hopefully your thoughts will be soon gone

Caddyshack

If it were my product I would like to spend a bit of time making it look nice....it is their shop window after all. f1 cars look right just out of the box. First impressions don't get second chances, why would they not spend 20 mins making it look right?

caprizetec170

to be honest looks grand to me all the machined surfaces are well finished, ya want to see the state of some of the cast components we get into work

Sonic Boom

iTrader: (11)

You need to compare the current ones to the early ones they were beautifully prepared seems to me now they are selling well they've stopped giving a shit. Hardly what you should expect of a multi million dollar company??
Rich

Jay,

iTrader: (4)

I think Richs point is if it looks un finished and rough why would the inside be any different and I agree if a so called top turbo manufacture wants to turn shit out like that only a monkey would trust there workmanship '

mk1turboestate

iTrader: (2)

I have to agree, it doesn't look great, I arrange for boilers to be fitted in houses and to me. One of the most important finishes it the making good, ( plastering and outside brickwork) as that's what most people can see when we have patched up, I think if you spend a decent amount on something you should expect a nice finish throughout,
If you shortcut a little finishing what will you miss that can't be seen

You just gonna cherry pick the comment you agree with and ignore the rest Mark?

Rich

I got a bit worried when I read the title that they had started falling to pieces or something as I'm still planning on putting that turbo on my Sunny.

Can't see the problem personally, no they don't look as nice as the original housings but didn't they have to switch suppliers early on in production for some reason?

Depends what you want from a turbo I suppose, performance or looking pretty? I know which one I'd be worrying about first

The aesthetics are bad. The build quality isn't, unless it fails!

xr2wishy

iTrader: (2)

You wouldn't buy a new car with dents all over it and accept it as doesn't affect performance would you.
The finish is shocking, try selling that on and convince someone it's not been in a fight with gravity and a hard surface a few times.
It'd be on the way back in my opinion, looks like a casting defect and no reason in this day and age for that to be churned out.

Sonic Boom

iTrader: (11)

The thing is the Chinese GT Garrett copies that Toyo Sport down the road from me sell for Ł189 have a much better finish to them i've never seen a worse finish on a turbine housing ever let alone on a turbo that costs over 8 times as much!

For all the it's not how it looks but how it performs guys I'll liken it to my day job;
I work for Severn Trent Water so when a customer askes for new MDPE service to be laided up there drive way we go out dig a trench remove the old lead or copper or whatever their curent service is made of laid a new length of 25mm MDPE and reinstate the footway and drive way clean everything up and Bobs your Nan.

Let's say we just dig it out leave all muck up against the wall/hedge whatever connect up the new MDPE and put some road plates over the excavation.
Then the customer complains (and rightly so) and we say; "Have you got water?" "Can you still use your driveway?"
"Whats the problem you have better flow and pressure now, it's the performance that matters not what it looks like!"

rich i think your bang on

and for anyone that doubts why rich wanted the turbo in the frist place should look at his videos .if he would like it to look like it wasnt cast in the hills in china thats his perogative

its not like they cost 500 quid

no way would i fit that turbo,
I ll give you Ł100 and get rid of it for you sure

Well in that case James Rich should send it back, threads like this will always get mixed replies, a bit like, what wheels for my Sapph or 3dr we see every week

Only a Rich can decided what to do, i know if i WASN'T happy with a product it would go back.

Mark Shead

Correct the rest is not worth the effort to reply. I have spoken directly to the actual designer of the efr and why the finish on the exhaust housing is like it is.
I have also seen the new stuff coming and it's even better.

Mark

Fullflush

Well it couldn't get much worse.

Gives you zero confidence on what the insides are like.

stevieturbo

It's a casting, with a typical rough cast finish.

I really dont see the problem ?

I'm sure you could have had either polished at extra cost if the external appearance is so important.

Engine blocks, cylinder heads and many other cast parts look equally as....cast

Out of interest...

Is that turbo using the genuine Borg Warner turbine housing with the integral wastegate that the units normally come with ?
Or maybe reason it doesnt say BW, is it's an aftermarket piece to accommodate the use of an external wastegate ?

MarkTurbo

Design changes to the current range or new models? And will it be worth waiting for it to appear over buying one of the current Efr's?

ajamesc

I'd be more interested in the rather impressive results these turbos give than what the external casting looks like lol

Does the serial no/tag indicate a genuine part with external gate ?

Yes a disscusion will take place with the supplier on Monday, I recieved a 7064 from the same supplier 2 weeks ago and the finish quality on that was as you'd expect no complains, the finish on this 7670 is dire.
Rich

Ye I saw that a while ago, just thought it was a one off, but clearly not

That link doesn't work mate, I've no doubt it's a genuine BW part just a terribly made one.

Good on ya Rich, the only way to do it pal if you're not happy

Rich, we'll have to have a catch up soon mate, Toby Carvery when your fixed is the car running at present??

Sonic Boom

iTrader: (11)

It curently runs just about to drive it down to Dyno Torque is was going to have the 7670 fitted and a new exhaust fabricated.
I'll still drop it down they can use the current turbo as a mock up even if it's to go back.
Ye Carvery sounds good to me mate

Here's the 7064 we got the other week for my mate Steve I have no problem with this one:

cossynut2

I personally think it somehow missed being cleaned up before the inner parts were fitted. It is not hard to clean up a casting so it looks decent. I had my T35 Hybrid turbo converted to a T38 with a billet compressor wheel by CR turbos and when I got it back it looked like new. Surely it was a mistake and they should take it back and clean the casting up?
Cheers Richard.

Jay,

iTrader: (4)

You should stop moaning Rich because sheady said so

Imho there's no consistency to the finish so why would you believe any difference in the internals ! Like you said from a supposed big company you would expect more

stevieturbo

That turbine housing is definitely as supplied with most EFR's ?...again because of that integral wastegate. Compressor cover doesnt look much different ?

Were both turbos from the same supplier ?

What about their serial nos/ID tags ? Are they both genuine BW tags ?

So is your new one mostly a case of your turbo supplier supplying their own turbine housing to suit the external gate ?

nixon_2wd

BW stopped the investment casting production and continued the production with regular sand casting to lower the cost of each unit. Thats why the surface finish is terrible compared to the older ones. All later model BWs are supplied with these sand casted turbine housings.

Remember that Garrett turbine housings are cast iron, vs BW cast stainless steel = MUCH higher pouring temps and MUCH harder to get a nice finish. Trust me, I have done some work in a foundary.

The compressor cover is slightly different as the 7670 has a larger compressor than the 7064...

My 7670 is the same as yours. It is, however, much better finished inside than outside.
