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 =

Yes I can see the water holes on that one

Ohh well looks like I will be going to a Garret GT35/40 later on down the track then.

    • Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.
    • Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using. 
    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
