this post says its a standard bottom end, pistons in the previous pictures of the bottom end look fairly standard and arent dome tops as i would expect in a high comp bottom end build.

no signs of a VCT mod that i can see (your "b-cam" was discussed before)

pictures of the head look to me like it has had a reasonable whack of meat taken off the bottom of it. if the car is running corn juice or race fuel only im thinking even higher than 10:1 11-12?

if thats not it at the moment im not sure what else it could be to give that big of a change

It used to be a 26 head... ??

First and last hot lap for the new engine, seems i have a high flow #2 piston :(

It was a rubbish lap too, I left the buggered tyres from Targa on the rear, as it always used to push. But it appears i've fixed the front end grip.

Geebuz Benny that's rotten news buddy! WTF happened? :(

And yeah, if that speed is reading true, you've got an outright contendeer there! The gearing is way different to mine too. I'm going to assume there's a technical setup glitch there somewhere?

Top speed was a big surprise. It's done via GPS, and is was getting data off 10 sats at the time. I'm pretty comfident it's accurate, the rpm vs gear calculates pretty close, and the lap time would indicate a good top speed since i stuffed the first corner so bad.

i'll have the engine out and head off tonight, but it looks like it might have been a clogged injector, as we test spreyed it at the track, and it didn't mist properly. #1 injector looked heaps better. I've been over the logs, and lambda was .71 at full noise, fuel pressure was 65psi, EGT was ~750 deg, and I couldn't hear it pinging (i've watched the video heaps of times to listen to it too). So i'm confused on what caused it.

What gearing do you have Ben? mine is a std RB20 box, and a std diff gearset (4.3 i think). unless a 4.11 got in there before I got it

I have stock 20 box, and I assume stock gears (4:3?). Yours looks a lot like 32GTR gearing, so maybe 4:11.

There's no doubt your thing looks to have some serious stonk :) Shame about the pesky injector :(

1:1 4th gear at approx 7,800 rpm shift I get 190klm/h.

GPS so accurate hey? Fark me! I come on to the straight at PI at 170-80km/h and I hit 233km/h going downhill, on a very long straight with a short braking area as turn 1 is ~180k/h. Yet you hit the same speed on that lap! I need to pull my finger out and get the Cossie registered so the R32 can go corn juice and more boost :)

comparing data from targa to bens day at the track the extra torque is what helps it punch a whole thought the air. during targa with the not so grate engine it would just about go backwards in 5th. they seem to have a fair jump from 4th to 5th.

what ben has also not mentioned was the massive tail wind he had. haha

it wasnt a grate day for either of us. but my blown clutch is a lot easer than the engine swap, again!

The tail wind at symmons is worth some speed.

Got the engine open tonight. Looks like all the damage was caused by the tip of the spark plug that was missing. piston is full of dents the size of the missing piece, and the side is smashed out of the exhaust valve. Still need to work out why the tip came off

    • 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
    • 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. 
    • 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.
