internal, and he is probably looking at needing to run ~15-17psi

Correct - Its internal but I plan on running about 20psi from the turbo (17 - 18psi at the manifold).

I'm getting a new turbo aswell. HKS 2510 :):thumbsup::D;):banana:

2510? Thats a bit small for an RB20 isnt it?

That's what he is after, something small and responsive.

Fair enough but I think that a better option would be an HKS GT28/35 Pro S - Extremely responsive turbo but big enough for real power gains.

Im expecting the 30/76 to reach full boost (20psi) at around 4000 - 4500rpm, it should start building boost from around 2200 - 2500 though.

Im not 100% sure though, your best off asking someone who uses a GT30/76 already.

mine starts building at 2500-3000 i get full boost at 3500

so 20 psi at 4 sounds about right

Its not how small it is but how you use it

I should be getting full boost (20psi) around 2500-2800, boost coming on around 1500-1800, and hoping to get 200kw at the rears or more, but with a mega torque curve (for a rb20)

Should be able to use 3rd when I was needing 2nd before at wakie, and I wont bog down as much at motorkhana's/Drifting

    • 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.
