r32 gtr not boosting?

Hi all,

Would anyone know why my freshly imported gtr wont spool up!

I've checked both turbo's for shaft play and how well they spin

and they seem ok!

I've also checked the wastegate's and they seem to move freely!

The car blows only a little smoke and nothing to worry about!

there are no holes in any of the vacuum lines or turbo pipes!

I'm at a complete loss!

All I can think of is the stock boost solinoid working?

Would any one be able to tell me where it is?

I've followed the actuator lines to the back of the engine but i lose where

they go!

Anyways any help would be much appreciated!!!!!!

I had the same problem with my also freshly imported r32 gtr ended up being the front turbo exhaust wheel. The stock boost control solinoid is on the driverside of the engine bay. It has to lines running to it one comes off the end of the cylinder shape and the other off the side. This one has a yellow band painted on it. If you blose compressed air thru it you should see the actuators moving the wastegates smoothly... Also check that the recirculation valves arent leaking and causing boost to be constantly recirculated. But first of all check out the turbine wheels. Make sure they are both still intact.

Hope this helps,

Deren

Thanks for the help Deren!

But just one thing....

What's a recirulation valve?

Thanks again!

      Well - they have arrived.  And they are easy on the eye to put it mildly... These only have three bolts - but for a start there is a key that fits with vacuum like precision..  And as you can see by my ruler, the interface is large..   I listened to a podcast on HP Academy about Dan (KiwiCNC) and I'm more than comfortable he knows what he is doing. R35 Bearing assembly should arrive later today so can mock that up for a look. Can't wait to get these on and get some brake pressure logging too. IMG_3860.MP4

      I would be very confident that they are the same parts (the 2 different SKUs). It seems very clear that you can drop the cam in the 2-way opening, or in the other opening. If you arrange it in the other opening in the same way that you see any other 1-way diff, ie, with the flat of the cam up against the 1° side of the opening, then it would work as a 1-way. It can only spread the ramps when driving forwards - cannot spread the ramps on overrun. It would then appear obvious that if you put the cam into the opening "backwards", that you would get the angled flats of the cam working onto the "points" of the 1° side of the opening, which would give you ramp spread in both loading directions. I do wonder if the forward direction of the 1.5-way config is equivalent to the forward direction of the 2-way, seeing as the cams are flipped and the angled surfaces on those would need to be the same on each side - AND - clearly when installed in either the 2-way or 1-1ay configuration they are not intended to work exactly the same (the ramp angles on the 2-way are 10° different between forward and backward, and the ramp doesn't exist in the 1-way config). 'twere me, I think I would rather actually have a set of rings that offered the 2-way with two different sets of ramp angles, say the 55/45 of the existing design and maybe a 45/37.5 combo for a less aggressive effect), AND another set of rings with a dedicated 1.5-way opening and a dedicated 1-way opening. The 1.5-way opening would actually have the steeper angle on the overdrive side that causes it to be less pushy than the forward drive angle, like you see in many other diffs. But really - if this Nismo thing is thought out properly and all those surfaces work on each other the way that they need to, who am I to argue?
