Engine out. That looks serious! Hopefully serious upgrades not seriously broken.

After my upgrades, I am sitting at 360 awkw @ 20psi. I did a subset of the original plan. The main thing is just how much nicer the car is to drive with modern injectors, better ignition and e85.

All preventative thankfully...

-head gasket

-head studs

-oil pump gears

-general inspection

-and engine bay respray

 

what turbos you go to make 360 @ 20psi?

That sounds like some good items to tick off before more go faster bits.

Still using -9s but 2psi more plus e85 etc.

good results, definitely could pump a few more psi in there now you're running E85 if you wanted.....

25 psi if you have head studs, head gasket etc shouldn't be too much of an ask.....

That's a lot of power for -9's, especially only at 20psi.  What other mods do you have?

Performance stuff:
Plazmaman intercooler (the smaller one not 100mm)
1000cc injectors
Walbro 460
AC Delco coils

Other stuff that may be relevant but probably marginal benefit:
Built engine
Trust front pipes
Apexi exhaust
Apexi pods

Are you still running factory intake piping?

Yes. Factory intake piping, BoV and manifolds.

that's what i wanna hear ;)

I got this divided charge pipe made not too long ago, if you are unsure about buying a whole intake piping kit.

Are you running any cams?  

I'm still running factory air box, so maybe that's my problem.  Or maybe because I'm running R35 injectors at factory fuel pressure.  I read somewhere that R35 base fuel pressure is 1 bar higher and that's why it can get that much power out of 570cc.  Not sure if that's true.

Just to clarify, the power output is based on e85 and not 98.

My cams are factory.

I recall reading that the air box is good for 400kw. I just felt like hearing some more whoosh.

As for the injectors, mine were rubbish and needed to be replaced regardless of any power goals. I thought that you needed a higher cc rating than 570 to support e85 (on an RB26).

already running the divided piping, pretty much a necessity...

ye 570cc injectors will get you nowhere near 400....

Mine should be fairly close to your modification list once finished @Robzilla32, only I'm keeping factory airbox but i'll be running some mild cams and slightly larger turbos...

My goal is 350kw without e85, that's why I thought the 570cc would get the job done.  I rarely drive mine and a full tank would last 2-3 months, so I can't really run e85.  I also thought running R35 injectors with R35 AFMs should be a friendly combo to Nistune. 

Getting closer at 315kw during my last pull.  Bought a 76mm Plazmaman but yet to install it, still waiting for my tuner's dyno to be repaired...

Nah, who told you that?

Any injector is Nistune friendly, especially on Feature Pack 1 and 2

      R34 GT-T cycling ABS pump

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      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.
