Duncan's Race Car - The Most Overdue Build Thread On Sau


Recommended Posts

yeah man that my favourite track for sure....launching the car over the curbs at suttons, heading blind over the flip flop....ahhh.....kids these days don't know what they are missing

anyway, back to the story......

Yup.... It's called OHS, can't build a cool tracks any more...... Lakeside built back in the day...... QR built for safety.... Enough said

So, that was more like a 12 year history lesson than a build thread, but I intend that the thread will change a bit from here. I’m not worried about saying what actually happens, both the wins and mistakes that comes with doing pretty much everything at home.

The plan from here is to do a pretty big overhaul on the car, and the target (although not essential), is the NSW Production Car round at Bathurst in April. Upcoming jobs:

Replace the PowerFC with a Haltec including dash and flex fuel sensor

Strip the interior and properly prepare it, eg removing tar

Remove unneeded wiring (I’ve only ever added, not removed)

Replace all bushes and balljoints, they are a bit shabby after 10 years racing and 15 years on the road

New fuel pumps, hoses and FPR

Rebuild calipers and booster, replace ABS

We have now done two complete rear cradles and two front ends and what looks easy is simply not fun when you come to attempt it.

Some of the factory bushes are such a pain to remove (even with a good press) that it was easier to pay Pedders to remove them.

Installing new aftermarket bushes or replacing old aftermarket bushes with new ones is a piece of cake by comparison.

Good luck with this job.

umm yeah, nah.

no updates from me, especially not on the new national holiday, "Nismo Day".

I have been working on the trailer mostly, added solar panel, battery, invertor, compressor, winch, cameras lights etc. Pretty big job but all sorted now and should be nice and convenient at the track

And now that's done, I need to sort the spares Neil and I brought back from the container the other week.

Then...back to this old girl!

Yeah mate the trailer is awesome, been quite a step up from the death trailer that we used for so long.

An interesting sideline from the weekend.....

At the Federal tyres tech night Mick Hart pointed out that the width of tyres are not always the same between brands, and that semi slicks in particular vary a lot.

So here's an example.....some Dunlop 245 and Federal 245 next to each other on the floor....

The pair of Federals are at least 15mm wider than the dunlops

As far as actual race car work, I've got this de-pressing pile to get to (you are dead right Charles!). Actually spent a fair bit of time trying to remove some 25 year old studs from a hub and had no luck; neither bashing nor pressing up to 5tonnes....the damn things were not about to fall out.

And some actual car work....I've been running standard sized wheels all this time, 17x8 which has plenty of clearance inner and outer to the standard guards. But Targa rules allow +2" so I'm looking to fit some 18x10s to allow rubber that will last longer....

Interestingly, what everyone says "fits" doesn't really....ie what looks good does not provide much clearance. I bought a set of light and strong rays in 18x 9.5 +12 but even with 245 tyres on and rolled guards there is less than 10mm clearance to the outer guard at full compression, but at least 25mm to the tie rod end and over 40mm to the inner guard.

So, stuffed if I can see the point of a 2" wider wheel that has to run the same 245s I put on 8" rims.....sadly that means these purty rims are up for sale and I'm looking for 18x10 +25 to +35 offset in a similar forged rim

In any case, rolling one rear is done, I'll get the other side and the front done next weekend. As you can see I took the spring off but put the shock back in so I could easily check the wheel over it's full movement. BTW if you ever do it, remember to disconnect the sway bar too :whistling:

ahh, you mean the "good news you can have certainty there are no rules changes for the next three years" rules? Thanks for mentioning because that would save me a heap of trouble....I can just run 33 gtr wheels and everyone comes back to my size :)

hang on, do you mean:

"along with the return of the previous rule in relation to Classic competition wheel sizes, which will come into effect immediately after this year’s Targa Tasmania. "

because that wouldn't affect early modern?

detail from the regs:

59. Wheels

Wheel make and construction are free provided they meet the load carrying capabilities of the vehicle. The

following size allowances apply to the standard wheel size available for the model of vehicle not including any

options or variants.

Modern SS and Showroom

Wheel diameters may be varied by a maximum of plus or minus 1”

Modern LMS and M

S

Wheel diameters and width may be varied by a maximum of plus or minus 2”

Classic SS and All Specifications from 3rd May 2015

Wheel diameters and width may be varied by maximum of plus or minus 2” to a maximum size of 17” diameter

and 8” wide unless the original wheel is larger in diameter and/or width in which case the original wheel size

shall be the maximum size.

Classic LMS and MS until 3rd May 2015

Maximum wheel size is 17” in diameter and 8” wide unless original wheel size is larger in diameter and/or

width in which case the original wheel size shall be the maximum size.

So I think it hasn't changed for me.

BTW looks like Steve may have a problem:

The following vehicle types will not be granted entry into the Modern or Showroom category:

• Vehicles made by one manufacturer and then modified and re–tuned and released as a

derivative of the original car under another name are not permitted.

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
