Installed this a while back.

The installation was REALLY easy, alot easier than what I have read on here.

Basicly you had to grind off one nut hole off the exhaust manifold where the heat sheld screws to and every thing else just bolts up.

Stock oil lines hocked up perfect and I just blocked off the water lines.

I didn't need to bend the actuator rod like some people have said.

Here are the results.

I also run a kkr480 on my rb25det and me and a mate installed it ourselves,

turbo bolted up perfect, just had to grind a bit of the exhaust manifold, oil lines bolted up, but i went into enzed and for $30 or so he put new ends on my water lines to match the same size thats on the turbo, then i just chopped the lines and used high pressure/heat hose 2 move them around to fit nicely, and towed car to my mech 2 get dumpipe fab'd up and cooler piping change a little,

comes on hard bout 4000-4500rpm, i just run actuator spring which is bout 1.2-1.3 bar of boost, bit hard 2 control boost in these things, only downside..

but worth every penny, ive done bout 5000-7000kms alredy on this turbo, runs like a dream

Yeah it has got a GMC or some Aus turbo reco company bandged on it. I dont think its GMC but that just comes in to mind, its some 3 letter name.

Yeah KKR480s aren't that big, this one came off my VS commodore V6 and that spooled it at 2800rpm for 12psi. Its around 3000rpm, well you feel the boost kick in hard as then look at revs and its doing around 3000rpm. will have to have a closer look.

Its definarly a KKR480 I brought it new.

Any way stock turbo isn't big enough because I want 300RWKW.

Also I did lean the living daylights out of it early on to help turbo spool.

Well not that lean like 13.7:1 Air Fuel Mixture.

Yeah I would get a boost controller if I was you, adjusting that actuator rod would be a nightmare.

I didn't think you could get 1.2-1.3 bar out of the stock actuator as my commodore running stock actuator on the KKR480 only saw 12psi tops.

Does it over boost at all in high revs? I am hoping I dont need to get the wastegate cut out so it flows more.

Ummm the enzed bit makes no sence... KKR480s are oil only.. I just blocked off my water lines. The stock oil lines seemed to bolt up perfectly.

finny mate, you sure got a 480 cause no way it would spool up that early and also if its a oil only turbo then what are the other two fitting in the turbo core for????. you might have a bitsa turbo cause every 480 ive seen has oil and water fittings

Also you will be very lucky to get your 300kws with a kkr480 they arent bigger enough for it.

:S

Mine is from JustJap its marked as a JJR480 but I thought they where just rebadged KKR480s... they look identical.

Maybe I am wrong.

It has only got oil holes.

ummm that sucks... I should have got one from otomoto :)

KKR 480 =

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      My BMW E39 528i touring

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
