At the moment I'm ready to petrol bomb it...

Yes, I'm trying to get something done before trackday, but it isn't going much to plan. Hopeful that it will be done.

Did you ever get the dump pipe crack sorted?

Yeah, the local guy down the road put a good 1/2 inch of weld on everything... Lol

It is all good I think, welded some re-enforcing into it as well.

Where the dump pipe bolts to the gearbox, was all cracked and blowing. But got that sorted.

Annnnnd I may have broken a R200.... The 9 inch of the Nissan world :/

So - pre trackday update!

This car started life as a SR20 Auto, so it had a 3.9 ratio diff in it, while all other SR s13s came with a 4.11. Was originally a Open diff, and the previous owner put the Kaaz LSD in it. I was finding that the combination of 3.9 and the largish turbo was hampering me in a few areas of every track that I use. There were sections where it just felt so slow as you waited for it to come onto boost again. I noticed that I was just about one gear lower than all the skylines buddies that I track with. So I made up my mind, and decided to go to a 4.11. That's where the fun began.

So I got a R33 VLSD-A off Pezhead, that uses 4.11 and is a poo diff, so it was going to donate its crown and pinion. I dropped everything off at Award Gearbox and Diff, where Terry, Trish, and Mick were going to look after me. I soon got the call that the 3.9 Diff wasn't coming apart, even after a 20 ton, and then a 40 ton press. Something in the passenger side Stub was bunged up real good! So what they had to do to get it all apart was very time consuming, and had me running round like a mad man!

The Case (the big cast housing bit) was cut in the rear to remove/disassemble the hemisphere as much as possible. Once that was out, a very large drill had to be used to drill through the end of the Stub, to the point where the circlip sits, to free it.

Thankfully after a few phone calls through connections (its not what you know, its who you know ;) ) I had a S13 VLSD from JLM at Rydalmere to use the case from (the shafts and centre being different), and a matching Stub axle from Stuart Wilkins out at Mulgrave. Both life savers!!!

So now I christen it "FrankinDiff".

Its back in the car, and ready to test on Monday at SMSP. Most probably a wet day, but will be fun.

Can you imagine how hard this would be to drill through??

Ahh, after many phone calls, and much scavenging... its back together!

I have access to a set of michelin wets, but can't really justify the cost of getting them mounted just for this day.

I'll run the street setup of Federal RSRs that have plenty of tread. Should be ok, not fantastic.

Belated trackday wrap up.

I had fun :)

Car was good, I softened it out as much as possible and ran the federal RSRs in the wet conditions, never dried enough for slicks. The last session was a possibility, but no time to change them over as sessions were combined. Found the RSRs very pressure fussy. I dropped 2psi out and it turned into a dog, so I had to top them up again. they were happy round 36-37psi.

Car never got off gate pressure boost, which was well enough for the conditions. Struggled for grip in turn 5 which had some arse clapping moments, also round corp hill made for some interesting driving.Brakes were fine - really never got to temp.

Diff was great, so glad I had the Kaaz to make things predictable, and the ratio was an improvement, even in the bad conditions.

Fastest lap was the last lap of the day, the last session was great, having a tussle with Dave for 3rd/4th. Unfortunately he pipped me by something like 0.15 of a sec. So ended up 4th of a field of 37, happy with that.

I'm going to dump Track vids now...

Fastest Lap of the day-

Having a bit of a spin up the hill.

Taking BakeomonoRicer GT car master out for a passenger session. Small brown stain in passengers seat afterwards.

So, what's next?

I've got to get the car ready for the upcoming RTDC day on the North Circuit in October. Nothing much needs doing, but might treat it to an engine flush and some fresh oil. Hoping for dry weather to bolt the slicks back on and hunt some GTRs and Emos. :P

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
