Nothing... I can't drive the bloody thing.

What I did at the same time as hitting a rock with the sump (well... just after it anyway) was driving it on a dirt road (done many times before but previously always on semislicks) on normal tyres, hooked it around a tight left hander with some handbrake at the same speed I'd done before but it slid a tiny bit too far out and smacked the right rear wheel into the bank.

This was just after I'd heard something smack under the car on an uneven bit of road, but there was no knocking from the engine, pulled over just down the road, saw there was rocks and shit embedded between the wheel and tyre but didnt notice the wheel was in until I'd gotten it home. Noticed the knocking from the FJ when I pulled over to check the wheel, switched it off, checked under the car for oil leaks, checked the oil, put more in for good measure. No mobile reception, no houses, after midnight on a weekday... SH1T!!!!!! Decided if i could drive it at very low revs a max of a km I could get it to a position that I could probably roll it home, or at least push it as there would be no more uphill bits, so I did that. Knocking got a tiny bit louder for the short time it was running (figured if it was stuffed it would need a rebuild or replacement anyway...)

Got home, jacked it up to take the weight off the tyre as I felt it could go flat from an imperfect seal, had felt flattish rolling home, back was swinging a bit but didnt look like it had gone down much. I didnt want to bend the rim of the Watanabe so I stuck an Enkei on the next day, noticed the wheel was sitting in a bit on an angle but thought some might have been from jacking the car up, rolled it up and down the driveway a bit to try and get it to settle but it didnt do terribly much.

Then I rolled it into the shed and forgot about the car until I went to get something from the shed the other day.

So I've bent something..... just dont know what it is yet

Only time I've ever hit anything btw... and I wasnt going quick at all, just like using the momentum of the car to bring the back out a bit on that corner, the dirt road is a bit of a shortcut between two good roads in the hills

I folded a wheel under my car putting it up a curb. I just payed a visit to jaustech they had a couple of arms laying round $150 which was a bit sore on the old pocket though.

However since then I have had a bit of a look at the wreckers and so on and from what I can see the mr30 sedan disk rear end is wrong on the caliper to rotor offset, however hatch back rear calipers fit on the rear DR30 arm and disc assembly which leads me to believe the hatch rear arms will fit up no worries, how ever I have never actually tried. If that makes any sense to you.

Hmmm, took the DR out of the garage and swapped the wheels off it so its sitting on the 16's and had a look under the back. I couldnt really see what was bent, it might be the arm where the axle goes through, it looks a little bit like the arm is bent in where it meedts the hub. Though it could also be where the arm mounts off the chassis... I guess I'll need to go and get all the MR30 hatch arms and then compare everything

Engine is running now, so I just need to get the back fixed.

Took it to a suspension / alignment dude yeasterday and he said that the arm probably needs to be replaced.

From what Bensdr30 said, the MR discs are smaller than the DR ones... but if the DR disc will bolt ono a MR hatch rear then that should be fine? I'll try Jaustech first for some DR arms I think

Adam,

The basic arm is IDENTICAL, it mounts to the same place, they are both interchangeable, BUT as Ben says, the rear brakes on the MR are different, they are only 254 instead of 290, the caliper mounts may be different as well.

The DR rear arms are unique as the HR's are same as MR & I just chucked a pair out yesterday. The original arms off my PNV, gone to the recyclers.

I have a pair of stock HR calipers here as they are very similar to DR. I will check tomorrow if the calipers can be mounted to the DR rear end etc and advise further.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
