I'd love to see a gtx3076r making over 400rwkw on an RB. The curve should be pretty nuts.

Even better would be someone running two of them, high mounted on any kind of RB engine bigger than 2.6L otherwise I suspect the lag would be too much....even though it would feel insane when it did get some meaningful boost and it would have such a short RPM range where it just piles on the power increase. Would be a wild ride!

but a built RB with a GTX3076 would sh*t it in. I will check out the HTA76 further Lithium but I think the compressor housing is a little too big. Does it still run the Garrett rear?

Are you talking about on the VQ? I was aiming the response at Dajae who appears to have a Skyline, wouldn't think it should have a problem there. The FP turbos have OEM Garrett housings, though as you seem to be aware all use the .70a/r comp housings.

I'm not 100% sure why people are excited about the GTX3076Rs tbh. The comp wheel doesn't flow as much as a GT3582R compressor, and a back to back dyno with a GT3082R has proven them to offer no better spool. There hasn't been anything yet to make me feel like they are something special, they flow like they are a bigger than a GT3076R and spool that way too - more lag and more power are just a typical trade off.

In all honesty so far I prefer the idea of a Kando T67!

Spool 3.4

Awesome! Mine is going on a spool 2.8 kit. They're a nice bit of kit, too :)

Thanks Lith, will look into the FP range. I know the evo guys have good results with them.

N1, makes two of ua mate! :D i hope to push that boundary soon :) and if the results look promising on the 3.4, even better :)

Yeh sorry, VQ.

I can only go by what Garrett's maps tell me, the GTX3076 flows more than the GT35 and the FP HTA. Hopefully they aren't talking crap.

That GT3582R compressor map isn't right... see from Garrett:

Either way, more than enough to way outflow the GT30 imho which makes it pointless having that much compressor imho. Again, I am not at all convinced that a GTX3076R will make any more power than a FP HTA GT3076R.

^ as above, can only but try. The compressor is not the only part of the equation, even if the compressor CAN move x amount of air at y amount of boost its irrelevant if either the engine, the fuel system, the other boltons, the turbine housing/wheel, or any other part of the car isn't up to supporting that power figure.

Air leaks are the worst one, you often can't hear them and they aren't bad enough to effect day to day driving, but on boost if they start wasting compressor flow will kill power.

I wish more tuners would insist on doing a smoke test before tuning a car these days.

Agreed. I think i have everything needed to achieve it, or atleast get close. Head has had some decent work done, although im steering towards oversize valves to help out a bit. And some decent cams. Im still reading up on threads relating to e85 though..

I hear good things about pierburg (spelling?) fuel pumps.. :)

The end of next week, not much dyno time needed, only enough to make sure the new TB and stuff is working right.

Goes in on Tues night or Wends morning which is when Ill drop of the sump for Stevo.

It will be good not to be loosing all that air, it couldnt even get the pressure up past 2psi (If I remember right) on the smoke test machine bottle gauge thingie as the leak was so bad. pinch.gif

Dajae - I bought a pierburg but haven't fitted it yet...I created a thread on my findings and what I can tell you is that it flows more than the aeromotive stealth by a decent margin but I can't recall the figures exactly.

As a comparison, Bosch 044 flows 200ltrs/min @ 5bar whereas the pierburg flows 360ltrs/min @ 5bar.

They are not cheap so expect to pay about $450 with a filter.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
