This happened when my timing was out a little bit at cruise loads, after a 15 min drive at 100km/h :) (just an oversight.. thats what you get when you drink too much rum the night before then try tune on V and Pies :) )

I have pictures of EVERYTHING! LOL. Like to keep my work documented.

Was that timing or Afr's? If so what was wrong Too lean Or 2 Advanced

Wasn't any recommended brands in there.

Also wrt to the boost gauge. Is it going to give an incorrect reading where it is? Or is it just not good to have it there.?

It's on the line that controls the fuel pressure so if it pops off for any reason then you can do some damage.

Try moving it to the back of the plenum against the fire wall just tap into the factor vac line

It will run off a nipple (har har I said nipple)

Heads towards the brake booster into a little black box.

If you cant find it send me a message and I'll take a pic of mine tomorrow

So if the timing is too retarded then the air will still be in a state of combustion during the exhaust stroke and this extra pressure that usually drives the cylinder down will begin to spool the turbo?

Why would an atmospheric blow off valve cause boost to build in neutral?

It won't.

They will all make some boost on free rev. Just not 10psi. More like 1-2psi and that's purely due to exhaust volume and turbine speed. If your ignition timing is retarded it makes the engine work harder/labour more and therefore will build more boost. Probably still not 10psi

^ Yeah from reading 10psi seems to be a bit. I can hear the turbo spooling up so I don't think it's faulty boost gauge. Builds boost gradually until I take my foot of the accelerator. Any idea? Ill try get a video up in the next day.

Still going to check the timing anyways.

Well I hope it isn't the timing being too retarded as my CAS has next to no adjustment left to advance it(Almost turned as far counter-clockwise as it can). I haven't had the time to get a timing light and really play around with it yet, just having study breaks and speculating/stressing out.

If the timing is too retarded and I can't advance it far enough, could this be due a mistake being made when the timing belt had been replaced?

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
