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


Recommended Posts

made some progress on Neil's Radical's wiring this weekend, but stuff all on my car.

I did get this snazzy pressing kit of ebay which made short work of the subframe bushes http://www.ebay.com.au/itm/231667756034

Just put a correctly sized sleeve above and below the bush

turn the handle (OK, lots, and hard), and it is done

press-end.jpg

voila

This bush pressing kit looks the goods and would make a great Christmas present (I will have to leave the family some hints that I need one of these).

I have had so much hassle trying to fit Skyline sub frames and suspension arms into the press to replace bushes where this will fit in anywhere and be so much easier.

what, lunch was unpaid? you are a harsh boss...

Well I figured I'd spent soooooooo many weeks working on your shitbox that lunch should be on your own time. 3 cheese and vegimite sandwiches and a couple of bottles of water should have shut you up. Oh it did take you a hour to remember where you were up to on my shitbox as well.

Don't stress to much,,, your old girl will get some lovin AFTER this coming weekend.

Don't forget to buy the carbon sheet for you firewall blanks.

Cheers

Neil.

Just make sure you have some bushes to press in on chrissy morning Charles,,,a kids gotta be able to play with his new toys.

Now back to the Duncan build.

How are we going to remove all the shitty interior black paint before a complete interior respray?.

Personally I was thinking we keep going with a total strip of the car and get all the cars paint removed, soda stripped or something, I haven't really investigated to much, but I can. Anybody got any good ideas?. Like she's just about naked now, why not keep going and fix her damaged bits and vinyl coat her outside and freshly paint her interior. We have never had her so apart ever and I can't see us doing this again for some years so this seems like the right time to get it done. Trouble is it means he won't get to drive her till mid 2016 which will not make him happy.

Thoughts People.

Cheers

Neil.

haha none taken....I am thinking sanded and painted to....but by a professional, not me.

I did the interior of the nugget with a spray gun and it came up shit. Plus it didn't look particularly durable either

f**kign cars. Post is a year old next week but still future tense. everything always takes much longer and costs much more than you expect.

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

there was a question elsewhere about the oil filter/cooler/thermostat system and I realised there were no pics in this thread.

I have a large oil cooler where the a/c cooler is factory. Upside down to help it drain if I need to. Custom bracket bolted to the radiator support and I'm about to add another bracket between the bonnet catch support and the bottom (top?) of the cooler because I'm not happy with how much it can move when bouncing over ripple strips

Removed the factory oil/water interchanger, mostly because they are impossible to clean once a set of bearings have been through them and they are $400+ to replace from Nissan. I now have a Stagea mount which angles the fitting nicely to an Earls relocator. Dash 10 Teflon braided lines.

Remote filter locator in right guard between the intercooler hose and the BOVs

Earls thermostat behind the reo under the headlight. This required a whole heap of fittings and strange angles. It also has mounts for temp and 2 pressure senders (currently factory and aftermarket gauge, I am changing the aftermarket gauge sender across to the haltech sender but the same basic setup.

The thermostat requires a lot of fittings but I think it's worth it considering the range of ways the engine is used; driving to events, cold mornings, endures, hillclimbs etc.

Slightly better perspective of location

Setup has been excellent, no signs of running either too hot or cold even in the most challenging times including 40o+ 20min rally stage

BTW, anyone thinking of doing braided lines, make them up yourself. They are straightforward with instructions and care. The much bigger trick is working out how to mount and route everything because fittings take up a huge amount of space.

Are you comfortable with the diy lines and fittings holding the pressure Duncan? I had one split and it made an almighty mess, lucky I was just cruising at the time. What are your thoughts.

well based on my awesomely wide experience of 1.....yes :) I guess it depends what failed for you, hose or fitting, and whether the hose was in good condition or possibly damaged?

I think enough people have used these types of fittings at all levels of racing to be OK with it. But it's a good reminder I should put some more padding around the hoses in a couple of places and monitor it for rubbing.

Its always good practice to either support/bracket both ends so there is no tension in the cooler or put some allthread throught both facesand put a nut either side of the flange faces to stop the cooler from distorting with heat, load and vibration. If they are in an easy to see spot bot a big deal but over the years have seen a few cooler split and dump oil over the track etc as they were not in visible spots to see the distortion from poor supported cooler installs

Good to know, mine failed at the fitting so it was probably a dodgy assembly, I was asking because not sure if its safer to go to pirtek or enzed that's all.

good to hear it was at the fitting really......making them was straightforward but there were things to check around the cut end of the hose and how far it pulls in while assembling that someone could get wrong. So far so good..

yeah I really need to support both ends I think, especially since its a big/heavy core

Yeah hose split along the length of the hose so probably wasn't cut right so with the pressure and heat split it. Maybe the Teflon coating was damaged. Worth keeping an eye on I suppose. Cheers.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
