Well its in and installed now, it turns out that routing the tubing is actually pretty easy... heres how i did it.

For an S1 R33

1. Remove the dash panel below the steering wheel.

2. Remove the lining that runs up the a pillar then along the top of the drivers door.

3. This should reveal a gap at the base of the a pillar.... run your tubing down this to get it under the dash.

4. take the end of the tubing and tread it through the existing hole in the firewall (located just behind the right hand edge of where the stereo sits, maybe a little higher)

5. this should exit just to the right of the intake manifold if your looking at the engine from the front.

6. Now comes the choice of lines to tap. The closest line is the line that runs to the stock boost sensor (little black box located in the back left corner of the engine bay when viewed from the front). This line leaves from the back of the intake manifold and runs straight left. This is nice and convenient, But if like me you have an apexi mech boost gauge, the supplied T peice is too big for this hose, so instead use the hose from the front of the manifold, its thicker and just like the one from the back... it will gauge the intake manifold pressure. For this i ran under the air intake and other leads to the front.

7. Cut the desired hose where u wish to join and insert your T peice.

8. Attach your gauge hose to your T peice.

9. use cable ties or similar to tighten the join on the T peice

10. find and attach gauge wires to power if applicable (i'm not going to tell you which one, just find on with power when the lights are on but non when they're not (lighter adapter for instance).

11. Depending on the length these wires can either follow tyhe tubing or instead shortcut down the side of the dash and under the panel removed earlier, dont worry when we put the panel back on it will be protected/hidden.

12. Next replace the 2 removed panels (the a pillar panel and the footwell panel)

13. connect your gauge to your hose and wiring and mount as needed....

All done with no hole drilling...

did i miss anything?

How do you keep the A pillar mount on? I put mine on with sticky tape for a week or 2 and then removed it because I wasn't prepared to drill and it looked dodgy with electrical tape holding it on. The only way I can think of that you can do it is to drill it.

You mean like a greedt apillar mount? or just a standard mount at the a pillar?

I am just using the gauge mount that came with the gauge for now (my a pillar mount is on its way, should have it in a week or 2) and with that i just turned it sideways and lodged it into a gap in the dash (surprisingly secure there actually).

As soon as i get my mount i'll post a follow up to this for it. that said if u gimme a pic of the back of the mount i might be able to figure something out before hand.

Ahh ok, yeah I was thinking of my dual gauge GReddy one. Pain in the arse it is. Anyone want to buy it? $50?

just to confirm, is the circle marked in green the "little black box" everyone refers to when talking about the hose that the bosst gauge should be "t" into???

if so does that mean the green arrow i have pointed to, is the right hose to tap into, as that hose is coming off the black box and into the back of the manifold.

does it matter where i cut off the hose and "t" it in or not?

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?

      Stagea Front CV Axle Question

      By S1_C34 · Posted

      I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.

      Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.

      Yep that is correct. It allows you to adjust the short throw range from what I can tell

      Car has been running great, I've put about 300km's of break in time on it. First thing that stands out with properly sealing rings is no more noticeable crankcase smell coming out of my catch can. This may seem insignificant, but the constant smell while driving around was infuriating. It's also nice to see my oil level remain stable. Two new issues have developed that I only noticed this weekend though. There's a very noticeable driveline vibration past 100kmh. I only noticed it now as I've been babying it under 100kmh in the backroads. This comes as no surprise as I'm running a one-piece shaft, and I paid zero attention to my driveshaft angle when I put everything back in. I also have a fair bit of voltage drop on hot starts. The starter audibly is forcing. No issues on cold start though. I must not have removed all the paint under my main block ground during assembly. I'll try and take care of both those issues this week once the kids are asleep.  I also received all the parts I was missing for my direct port setup. I will hopefully have pictures of that up soon. I'm hoping to get back on the dyno the week of June 30th as I'll be on vacation. I'm confident I should be able to make north of 500rwkw on pump gas and WMI. I'll go back again later this summer with E98, but I want to confirm my ethanol content sensor is working properly first. I've never seen it read anything but 11%. This makes sense for our 10% ethanol content pump gas here, but I would expect the occasional movement between fill ups.
