hey,

everything is pretty much sorted. cooler piping, tailshaft, gearbox mount, bonnet shutting, rad, etc.

But am just a little unsure on a couple of pretty simple things.

1. have had the plenum refaced, with the throttle body at the front now. However throttle cable doesn't reach. Can it be extended, or do i have to get say a bigger Vl, r32, r33, or other cable.

2. Am not running a bov, so can i just get the rubber hoses which go the bov blocked off at the plenum. The black metal piping which leads to the bov on the turbo side have been taken care of.

3. With the new cooler piping there no place to plug in the vacume line for the wastegate. Can i just extend the line and get the reading off any part of the plenum, or is getting it off the cooler piping on the turbo side essential.

4. for the boost gauge reading, does that just get it off the plenum also.

5. for the vacume lines which go to the throttle body, now that at its at the front, is just getting a bigger line ok, will it effect the throttle body opening, and operating the way it should.

6. whats the best way to drain the fuel tank?

any help much appreciated. i will post some pics as soon as i can get a hold of a digi camera.

thanks again

jsut puta nipple in the cooler pipingand run the line from there

you might need a custom throttle cable

ps I want a ride when its done

boost gauge jsut off the plenum

also run into another problem.

power steering setup. The silvia has some some speed sensative unit. and theres 4 lines coming off that, yet theres only 2 spots on the rack.

And putting in new lines mite not be viable cost wise at this stage.

Just wonderding whether i could take out the power steering lines, pump, put fluid in the power steering rack, so it doesn't run dry, and block off the outlets and inlets, so no fluid can go in or out.

only worry would be whether the rack will suffer, or turning will be come impossible.

Anyone know what the go is.

Is it safe to do? or should i run new lines, but then if i bypass the speed sensative unit, it could cause problems up at high speeds, pretty tight for room with this one. and i got lines going everywhere.

thoughts on this please.

oh and i got the tank drained, hooked up old fuel pump ran it off a battery and pumped the old fuel out through some hose. worked well.

GTiR throttle cable fits on R33 with front facing plenum. I have been told you can get the stock cable modified as well.

Two spots on the steering rack? why not use an R33 steering pump? I think the R32 have like a dual pump with two lines for the rear hicas, and two for the front steering. If your pump has 4 outlets, do 2 of them run from a seperate resevoir? Sorry I dont have much of an idea what is exactly wrong with the power steer - but interested to hear what the problem/solution and outcome are?

Cheers

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
