Hey all

Just a quick question. I've recently bought a brand new gt3540 and i noticed the compressor housing looks different to other garrett turbos ive seen before including other gt3540's. All the others had the a/r stamped on the compressor housing and had a rather smooth surface. My turbo compressor housing doesnt really have anything on it and the surface is a lil rougher. I had a look on the garrett website and the picture of my turbo on the website looks the same as mine so i'm not overally worried but i admit i still am a lil as i've never seen another with the change. Has anyone come across this before or know of any change in the casting process?

cheers

did you buy it from slide performance? i got mine from them and mine was identicle to urs (also a gt3540) so i took it to my tuner and he identified it as an genuine 3540 but with the old comp cover.. i got slide to polish mine up free of charge :(

Kemp, who fancy drilled those covers, not Mr Turbo jobbies are they?

Cheers

nah they arnt mr turbo job's

u see the 2nd turbo from the left?? thats mine :D i'll be puting that on my GTR but B4 it goes on the GTR im gonna put it on the 180 and gas it and see if i can crack into the 400rwkw mark with a SR20

the turbo's full custom the compressor housing was machined by ATP over in the states and the exhaust housing is a custom in-house casted exhaust housing

its a T4 flange and its divided aka twin-scroll/spit-pulse A/R .70 <----- thats right its not a typo .70 u guys have any idea how responsive thats going to be and it will also have enuff top end to make over 400kw

the housing can not be bought from garrett because garrett dont even make them

The SR setup should be wicked, good luck man!

*waits for Disco to come sprinting over, all frothy mouthed and sweaty palmed over the TS setup*

i seriously cant help it aye

my mate made more power then me and i wanna blow him away so im gonna up the turbo and gas the car just to make it in the 400kw mark which has been done with the SR20 B4 but ive neva done it so i may as well

the GTR project will have to wait the 180 is more important to me right now

i got mine polished because it was ugly, had a burr mark and crap on it.. got it polished thru slide, as i wont be happy and say "oh na its ok i payed 1700 for a turbo and its not what i like" f**k that. I would have gone to the extent and flown over to see jason myself.. and made him change the cover or polishd it. simple.

ill post a pic of my turbo when i find a pic :)

also the manifold wasnt the best, rob hadto do some fab work to it, cut it and move the turbo away from the head, cut the external wastegate flange off and reweld a new one in from the side just under the flange. so it looks different to how it is when we dummy fitted it.

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
