Is fullrace the best place to buy efr housings from?

We have more EFR turbine housings *in stock* than anyone else (BorgWarner included)

Treadstone and turbozentrum are also selling EFR housings.

Before you buy EFR turbine housings, make sure the reseller has it in stock... because if its not on the shelf, it can take 4-6+ months to get loose housings

I knew they didn't have stock when I purchased but I am happy to wait when I paid ~$900 less than retail

 

Im always hearing of shops taking orders for turbos they can not possibly deliver.  I dont fault them, because they think they can do it.  But in reality production on these turbos is so spotty / low volume and backorders so severe - if the reseller taking your money does not have the BW turbo in stock, I'd bet you won't see it within 4+ months.  Maybe you will get lucky and prove me wrong.  for your sake I hope so!

These turbos are the best f**kin turbos ever in the market and in a big turbo guy but the 7163s are insanse and I had a mp2 r34gtr fully built tomei greddy and all on low boost this bitch hauled on high boost it didn't wanna stop ovisly have to uprgrade bbk time then but I sold the car and upgraded to nur r34s

^^this kid is a maniac, cant ever understand much of what he writes.  his brother is a customer of mine, owns a shop with multiple built R34's and twin 7163 kits on 2.8L tomei longblocks

Note to all. Finally moved my cam gears on the dyno. Spent 4 hours there yesterday (on a dynocomm inertial - which will soon be eddy brake). I now see what a V-cam would do for you. Moving my Pon

I have always bought my oils through Sparebox, always quick deliveries, no drama

Oils and simple things maybe. Not something like efr turbos and parts where the only thing in stock is a photo. Then you could be strung along for months and months.

Also when you pay $14.95 for express shipping only to be told 2 weeks later that's only from the date of dispatch which will be months away when stock 'may' arrive sort of defeats the purpose of paying for express shipping.

I know what you mean, I am now waiting for a spring (pivot) to come from Japan, I ordered a pull push clutch converter from another company for an ATS carbon triple because my EFR8374 and new tune  pushed the 1000Nm to 1309Nm and the coopermix twin could not handle it. They sent the kit in two separate deliveries and as soon as I heard  that I knew there wold be a problem and there was. I was told told by them there was no way I did not receive the spring, shit I opened both boxes on the same bench and took a photo of the contents and sent it to them so they could confirm it was all there. They said they would "only" charge me 50% of the price , I paid the full price and said when the supplier does a stocktake and finds the extra spring they can reimburse me 100%, fat chance of that, lol

Works just fine... just not with a 3.2 and 8374 hanging off it ?.

Offer the Petey a price, I'm sure he will take it.

Had enough of dealing with short supply. Looking at canning projects and buying one of these...  Alfa Romeo giulia qv. Does anyone know much about them? Looking at getting one towards the end of year.Screenshot_20170510-165955.thumb.png.95db05a0760cae1376bc911f660ad62c.png

Pretty sure this is the wrong thread for this.

What section should I start a thread in for this one?

Might have to start your own , maybe "Alfa or Nissan what to buy" or go to an Alfa Site and get your answers from blokes that drive them and like them.

Then put an EFR on it and come back to this thread, lol

The conversion is more so to put a stronger box in rather than chase even more response.

Need a strong box as these 5 speeds just keep popping with ~500kw and my driving style.

I'll change the diff in the future if I feel the 4.11 diff is too annoying.

Everyone I've spoken to who has done the conversion with the 32/33 diff loves it. See how we go

The short ratio getrag together with 4.11 diff has transformed the car.

Its so much more revvy. 30 psi snaps on much harder and revs out so much quicker. Its actually hard to hold it in a straight line. 

I tried to record it but my phone holder couldn't  hold the heavy ass s8+.  Ill try again with a sturdier holder.

All 4 wheels light up slamming it in 2nd on gate pressure. Think the old single plate may have been slipping.

Crazy fun car now. Feels like it has much more low down take off. Can put around in 5th without needing to drop down a gear.

Highway driving is a little annoying with it being at 3,000rpm cruising at 110km in 6th. And the box is noiser from the twin plate and conversion but its a small price to pay for how much more fun the car is rowing through the gears.

:D

@Griffin Start your own. Nothing you mentioned has anything to do with the thread title, which is 'Borg Warner EFR Series Turbo's V 2.0', fyi.

@Full-Race Geoff You might have missed my previous question, but are you aware of any videos of cars using the twin kit? I could only find one video with BMR's R34 on the dyno, but none on the track/road/strip.

hey sorry I didn't see your post.  on the GTR.co.uk forum there are a few guys regularly tracking our twin kit.  Richard / CT17 on gtr.co.uk has posted some videos,

 

his feedback and dyno chart are here

  " Having now used my twin EFR 6258s I am very happy with them.
You can feel them spooling up at 1800rpm on my car and apparently I have 1bar of boost at 3,000rpm.
They come on smoothly and it feels more drivable than the low mount twin -5s with billet wheels I had before. "

 

" Yes although on the Dyno it's almost exactly the same the car is more able to use the power now on the road/track.

They spool up a bit smoother so the surge of power isn't as instant.
Which means it spends less time wiggling the rear end and trying to deploy the power and more time just taking off.
On the same tyres it used to struggle in 2nd to put the power down and wiggle a bit in third. Not any more.

Overall it's definitely made it quicker.
My car was well set up before and did spool very early, but it's definitely smoother and easier to drive now.

Driving it you can feel boost around 1800rpm and it's going properly by 3000rpm. "

I would imagine that the dyno result is on regular pump gas (93 octane)? Thanks for the info @Full-Race Geoff. Good to see other people with the twin kit. I grabbed the 6758's so I would expect a little more power over the curve past 3500rpm (spinning to about 8k) I believe.

8374/1.05... Will the 1.45 ass end drop straight on without dump mods or will the snail sit taller?

We tried to have a play last night but without pulling the turbo off bit we couldnt confirm.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      Duncan's V37.......race car?

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      By Duncan · Posted

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      R33 persistent issues. P/steering and lag/misfire

      By MissMintyR33 · Posted

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
