unfortunately that is a characteristic of bush bearing turbos.

expect about 1000rpm over the same size ball bearing turbo. I know the pain too well.....the race car runs standard n1 turbos which are big bush bearing ones.

I don't think its 1k more. lol. Possibly 200 revs more to get it spinning, then a faster ramp. It will come on much harder with more top end if tuned right. (with the Sierra wheels anyway.) People under-estimate well built bushed cores, the 360 degree thrust washers make a huge difference.

I have much better response than Craig with his Garrett core, he has a slightly larger turbine on his 3071 and made about 20kw more on petrol.

Deleted the VQ35 Throttle body warmer/coolant loop today. $2 of clamps, quite a bit of swearing- bloody tight some of these places on these cars!

You VQ25dets have the same system? You might find you got your lovely HDI intercooler only to be running air through a 70oC Throttle >_<

Well, I finally bought some engine oil for mine, and am thinking of buying one of those Fumoto sump plug drains to make life even easier again! I've already got an oil filter relocation kit, so that helps!

do it mate, so easy.

changed the oil to castrol edge 0-40, new ryco oil filter & will do the fuel filter change after next 10% eflex fuel mix; just to clean any crap out of the system.

changed the brake kit bolts to 14mm from 12mm, like I should have done at the beginning, and added some squeal brake goo.

thats it for a while, need to regas the A/C and get a wheel align.

huh...photo's...what you talking about?

In a VQ35 the intake is heated via a coolant circulated around the Plenum, just behind the TB. Basically takes it right out of the main metal coolant lines.

It circulates up into the Plenum via a small rubber hose and then back down the other side behind the motor.

You can see in the pic, companies sell little gadgets to re-route coolant past the TB, but all you really need is time, a bit of brass pipe the right size, and a couple of small clamps.

Edit - the reason its heated is to stop the TB sticking in below freezing climates. So don't do it if you live in the snow. If it never gets that cold where you are, its just making your intake hot...

make sense?

I guess no need since your intake is exhaust heated...

Whats a guy to do if he found a very cheap Z33 HKS GT3037 turbo kit...? Thoughts?

As per dcdc! Now your talking...will the little woman approve though!

yeh its not that much worse.

i find that its hitting full boost at 4000rpm.. before i was hitting boost on 3400rpm

and that was a stock sized turbo but just ball bearing. so basically immitating stock.

my fans now I think are the same size as craigs(almost) so im kinda happy that its not that much worse.. you just notice it without a tune i guess.

Well I dropped the car off at RVO in dandenong to get the shift kit installed, and to have the line pressure ramped right up "without braking anything" Ive told him I atleast wanna try and get a year out of it so i can save for a full rebuild, or to do the Manual/rear wheel!

I know half of you Sydney boys want it done so I'll be sure to let you know once I get it back tonight!

for people in melbourne, $550 installed.

I think for those sending the valve body down it's $450.(+ whatever shipping cost's)

Ahh that's right...the EMU Trans fix that Cihan mentioned has something to do with upping the line pressure...

doesnt change the fact you will still need a shift kit. for the power your going for though Cihans emanage hack should fix it..

How are they upping the line pressure?

How are they upping the line pressure?

who? the trans joint or Cihan.

Cihan's I think adjusting this through the emanage, he says he thinks he may have found a way to get around it.

RVO Automatics, with a shift kit.. f**ked if I know how else.

    • 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!
    • 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 
    • 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

    • 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.
