I was wondering what brand of twin turbos members in Australia have installed on their cars and their experience with them.

I have Super RB EVO 17T turbos on mine currently with 14,000kms on them. There has been no issues with these and they have performed very well. Before these, I ran the old Classic RB turbos for 29,000kms and likewise, had no issues but these were worn out and required a rebuild.

Pure stage 2 highflows. Great turbos , run 10s on them and they are a great daily drive.

lots of people seem to be going for chinese wizzbangs these days... probably because they are cheap

[kookie]

That's due to the platform being so old and "affordable" now

[Coupes33]

I am surprised that there is not more responses here. I know a lot of people are going the ST route nowadays but I thought there would be still quite a few running aftermarket twins in Australia. Maybe they are not members of this forum.

[Brule]

There's alot of people on facebook.
The bosses are vtl and phil and a couple of others I dont know.

I joined 3 months ago.

Overall the most popular turbos are stock ones.
However theres a few pures, china, even a mmp setup lol and a few single setups, 1 cool one with built engine and 6870 looks real nice but not going yet.

They would be blown away hearing your rbs doing 133mph and 10.7 or whatever it is.

That's because they go "Whiiiiz!!!" when the fly past you and then "BANG!!!" 100m down the road.

Pure S2 Hiflow

[Coupes33]

You guys who are running the Pure S2's. How has the reliability been on these? I know from a performance point of view, they appear to be the best twins in that area. The quickest time (record for twins) that I have seen is a 9.8s for a N54 and they hold the record for the S55 at 9.3s. How many kms have you run them for?

Phil had a set which rattled not long after they were fitted, then started smoking with less than 5-7k on them.

- Phil sent them back to pure got them rebuilt, got blamed for oil contamination,
- They arrived with old looking wastegates with tons of play.
- Sent them back to pure again, got a condescending response saying they are supposed to have play in them
- Sent back to us with the wastegates replaced (getting quite expensive with postage now)
- Phil went single turbo and sold the turbos
- New owner of the turbos fitted them and smoking again, then sold the car as people usually do when this happens

Thanks Vince for that information. Certainly not a very good experience and one that would surely put you off using Pure turbos. RB had some similar smoking issues reported 8 -9 yrs ago. I am surprised there are no posts from members using GC turbos as Tony Vargas is always stating he has sold 100's of these worldwide but I have never read any posts apart from Marty, on how they perform. The quickest time I can find is from Tony's workshop car which is lightened, roll cage installed, 6spd sequential transmission and built engine which was a 10.7s the same as rev210 and mine.

Great. Mine have had 28psi thrown at them now. Company stands by a rating of 30psi
From memory, although your motor might not like that.
Turbo installs on these cars can't be half-ass (true of any but, N54 is a bitch). The oil control hurts them so drains and proper oil breathing is important, as is compressor surging. It's pretty easy to root oil seals regardless of God like build quality if something is out.
Pure 2 hiflows have built that reliable reputation, not sure about the 600s so much though.
They aren't the biggest turbo out there ,in fact they might even be just TD03s still, but they do deliver great levels of power.
Of the newer big players like 19t chinas , RB Gfs , VTT F-RBs and hydra800 . Hydra800s have what looks like the best runs on the board so far , with the others showing promise but, not yet reaching claimed potential.

I don't think we have seen china 17 or 19ts do any 10s yet ?

M18 released that alloy cast high mount turbo kit now, it's cheap and looks like it's got room for RHD downpipe too.https://www.m18performance.com/produ...8-n54-igem.htm

Agree that the installation process is key to reliability as well as maintenance. I have installed my 2 sets of turbos, changed oil and filter every 5,000kms and reliability has been great. Also, I have the large RB oil drains installed. How many kms have you got on your Pure S2 turbos?

[Hoper]

I'm running dynamic autoworx 775RS which are basically TD04 17.5t

Have had them on the car for around 10k km now, all good, note that I had an email conversation with DAW who told me they were good for up to around 21PSI and above that I might have issues

So they run at around 20PSI with the current tune

I did ask RB about warranty etc before buying the DAW turbos, was told they wouldn't honor the warranty if I installed them myself

I understand their hesitation, but that sealed the deal for me, basically as I do all of my own work on the car, I can go through 2.5 sets of DAWs for the same cost as 1 set of RBs and DAW tell me they'll honor the warranty, but I haven't had to try it out

No idea what it would run the 1/4 mile in, but Tim tells me it's around 350rwkw and 700nm at the wheels, which is plenty

Going on almost 30,000 km. Lots of power going on. The last time.it saw a dyno on e60 and lower boost it was over 400rwkw on dyno dynamics. It would be a fair whack more now.

At 20psi boost, most aftermarket turbos should last for quite a while. What fuel are you running Hoper? As far as warranty goes, I guess there is slightly less risk associated with a workshop than someone doing the job themselves. However, I rather do it myself and take my time to ensure it is done correctly. For workshops, time is money so the job is done as quick as possible. Are you planning to run yours at the strip at some stage?

When do you think you will run yours at the drags next. Hopefully, you should lower that 10.7s time next outing.

Good question. Maybe soon. I want to give the V70A tyres a go. I have an annoying timing correction issue when the E content is higher. Have just changed to eldor coils after one of the original Bosch one died. It reduced it but, still there. So hunting it down.
It's possible I need to clean the PI injectors out, as E85 does create gum and fuel cleaners don't get to PI injectors unless you are boosting.

On a related topic , I have been considering the VTT outlets for RHD . Given our dented up factory one and the power levels.

What have others done in terms of outlets and what are our thoughts on them for upgraded turbos?

You have mentioned before that you have been chasing timing corrections. Hopefully, you can sort it out soon. I have always had timing corrections and could never solve the issue apart from when I used octane booster with 98 fuel and they disappeared. Ken Atkinson said the timing corrections come with the N54 engine and not to be greatly alarmed by them. With outlets, I originally installed a set of RB outlets with the Super RB EVO turbos. They worked ok but were a pain to install and required either installing a LHS coolant expansion tank or modify the RHS tank. I did the later. Also, the rear pipe required strapping to the body work so as not to foul the steering shaft. Eventually, I fabricated a set of aluminium outlets which didn't foul with the steering shaft and allowed the stock RHS coolant tank to be installed.

Hi Coupes,
Not planning on taking the car to standing start drags, I don't have an LSD yet, it's a manual and I'm not sure I want to put my drivetrain through the launches that drag racing requires

Would also require some drag radials I guess

I am going to head to the roll racing in Sydney soon and will also rebook my track day soon, missed it due to COVID

So I won't have any 1/4 mile times to share but will be able to let you all know how it goes around a track and how it fares at the roll racing

also since my engine now has forged internals, I do watch the single turbo updates quite a bit and may eventually head down that route if my twins play up

oh and yes I trust myself far more than any shop, I care deeply about the outcome, it's hard to find shops full of mechanics who'll be as careful as you can be yourself

engine now has 10k km on it post re-build, has freed up quite a bit over from the 5k-8k mark, and like everyone else, timing corrections are a thing, but the more octane I put in the less I see, so more fuel upgrades on the horizon

I'm running E40 at the moment, and sometimes up the E content to check what it does, e50 really stretches the fuel system on my car, so a stage 3 lpfp and helix is on the list now

[JimiP]

I've been running GC's for about 2 years now.. Ive put about 30,000kms on them at 20psi making 300rwkw on 98.. they do rattle a bit but I run the MHD rattle fix set all the way to the right (less lag) and its OK..
