Every skyline i have owned has a hole next to the brake booster where you can stick wires and lines threw the firewall and meet up with a gauge on the pillar...

However after 3 hours of swearing and scratching a mag and breaking 2 clips... I still cant find a way to get my boost line threw the firewall...

The BLITZ SBC-i-D III will go threw where the main loom comes out under the A/C piping no problem at all. However i dont want to have to get 4 metres of hose for a boost gadge....

What have other series 2 owners does to plumb theirs???

I would also like to note, dont drive with your dash sitting in the back seat. Cause you need the hazard light button in place to indercate left or right. I got honked 4 times yesterday afternoon on the way home from a mates place, im like im sorry, i was using my hands for right hand turns. But people just dont care, and its the ones honking who usually dont indercate.

Wanted to get away from drilling a hole.... Bit hard to drill next to brake booster any way....

Even harder drilling from inside....

Might have to run 4 metres of hose.... Looked at pressure loss over 1 metre of hose and it like 0.004psi so 4 metres will not make a huge problem... So i guess ill just have to do it this way...

Any further ideas would be nice....

After 3 hours of pokin' around under the dash, i ended up pulling the grommet connected to the bonnet release line. I found it after following the bonnet release line into the firewall, and pulling away a tiny bit of the insulation there was a grommet approx 2cm wide.

Then it was all a matter of threading through the hose (which was pain to get through to the engine bay)....

if you follow the bonnet release from the latch inside it will head almost straight into the fire wall.. there's some insulation there and behind the insulation is the grommet which you can pull out. Now it doesn't got straight into the engine bay, but heads up abit....u'll ne some LOOOONG cable ties or something similar to push it up and into the bay.

Lemme know if u want a pic... it's too dark @ the mo & i don't have a flash... hehe

There should be a grommet with a bunch of wires running through that you can see if you remove the plastic inner guard. They run under the drivers side guard to the fuse box i think from the dash.

Push the end of a bit of coat hanger though it, tape your boost line to it, and you should be right.

I found the bonnet release cable... But this is a Blitz AC Race series gadge which uses 3/8 vac piping not that little 2 mm plasic tube.... Gonna have to drill a hole...

The main harness on a 33 goes through the firewall under the AC piping... wrong side of the engine bay... If i was to do this id have to run 4.5 metres of vac tube.... Not Cool

When i installed my boost gauge on my series 2, i used a hole on the drivers side which lead down under neath the dash near the accelerator. I wouldnt be going through all the trouble of pulling wheels off or drilling holes in ur firewall.

If u are still stuck i may be able to get u some pics tonight

:(

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
