Was having a dig around and given I have brand new bushes sitting there for a stock front swaybar, I'm going to run that at the next track day in early July with basically no other changes, beyond the breather setup and some tyre pressure changes, and see where that gets me. 

Testing is more important than times at this point, I want a neutral car that's kind on tyres before buying new ones. Plus time improvements through suspension tuning feels more rewarding to me. 

Buying new tyres is easy and can come later. 

Car is currently up on stands again to do a quick manual brake bleed and see if that power bleeder did a poor job or if the really light pedal is just a result of too big a booster/master combo.

Swaybar in and breather setup done.

Could trim hoses to make it tidier but this is just proof of concept.

If this doesn't help I will make the crank case can atmo.

Will ship the car off to tuner for a touch up and then it's​ ready to go.

Everything else I have in mind is a nicety rather a necessity before July 9th.

Car booked for tuner on Wednesday, will get him to pop in a new rear extension housing seal also to see if that stops the leak. Grabbed a new filler and drain plug to replace the originals also. 

Grabbed a sheet of Aluminium composite for splitter V2 and marked it up, evening out some imbalances and measurements in the original. Managed to somehow end up with 3mm instead of the 4mm I wanted, but should still be OK I think. Will see how it behaves on the car when mounted and then brace/replace if necessary. The old one had a brace which added bugger all weight. 

A quick weigh and estimate shows I should save 4-5kg at most, not a huge saving but will look neater and any reduction in weight is a good thing.

Won't be extending back to the engine mount as I did with the original as the swaybar "can" foul it under hard cornering at this ride height. This stops just short and allows the swaybar to move as needed. Using the stock swaybar for this round may negate that, or I could raise the car, but this way I know it doesn't matter what I do there will always be clearance for the sake of 20cm less.

Yep, swapped from SAFC/SITC to Nistune, didn't show up any ping until pegged for 4-5 hot laps then started to ping a little in 3rd. Will get him to wind some timing out and go thrash some more on the 9th. 

 

 

  • 2 weeks later...

Picked up car from tuners, took some timing out and added some fuel, lost a few wasps as a result - Felt the same on the drive home. See how it goes knock wise. 

I had a new extension housing seal just in case but it turns out my hunch was right and the box was mad overfilled, drained, new filler and drain plugs also. 

Made solid progress on spliter, just need to drill holes for edging and fit that, has a touch more flex than the old one, but will save 4-5kg and not look so ghetto. Straightened up my intercooler also, which was a pain in the ass.

No other changes planned before next track day this Sunday. Next thing will be tyres, but I'm tossing up going 235 RS-RR or buying some better offset rims/adding flares and running 255 all round. 

Been sniffing around for a passenger seat also as it would be good to take some mates for laps, though their fat asses will slow me down ;)

Big day yesterday, lots of laughs and heaps of fun.

Day started out wet and the first session was very ginger, car felt not too bad in the front end and I went faster than a few of my mates in higher powered cars :D Can see how hard it was to put power down towards the end of this clip.

Ran 8-9s slower than PB lol

 

Got faster as the day dried out and was convinced the car felt like it had better front grip with the softer front swaybar and maintaining 28psi hot on the tyres.

Got a bit carried away in the 3rd session and cooked the tyres then fluffed the entry to a corner and decided to just go with it. More lols. 

White balance did some weird shit in this clip as the sun was coming out and going away. Might be time for new camera, this one has been dropped a lot...
 


Kept adjusting damper settings and maanaged to shave .7s off my previous PB and run my first 58 with a 58.8 and a class win by 2 hundredths vs a GSR Lancer. Are all GSR AWD? He had better tyres but no idea on power.

Car had no knock but was a little rich and a bit doughy off boost, still work to do there. 

Catch can version eleventy got one more mod and worked well. I disconnected the moroso crankcase evac valve and vented the sump catch can to atmo, instantly no more oil in catch can. Will tidy it all up and leave it atmo and delete that one way valve, has not solved a single issue in the end, not sure why the V8 guys rave about them so much as I confirmed with Moroso my setup was correct for a turbo car. 

Splitter V2 held on OK but needs a little more bracing and some improved mounting points on the car to reduce flex. 

From here, car will probably sit for a bit as we come into wetter weather. Will tidy up breather system, was looking at Cams/Turbo, might be time to go 17x9 all round and get some 255s on it. The club guys are getting 18x10 slicks for $50 a pop but getting a 10" wide on the Silvia front end is a big ask. I might just stick with the RS-RR and stay in my class, but either way I am going to have to buy rims. 

Pics of team Nissan at the start of the day. GT-R won his class (and got chopped by me in the wet and overall :D) V8 Skyline next to him almost matched his PB and finished just outside the top 10, did me in by .5s and managed to kiss a tyre wall, cleaner 33 on the end with semi's got into the 56s with a PB and finished 5th outright for the day. I finished 16th overall in a field of 60 cars and outright fastest CA18 ;)

You know I've been looking around so I take interest in the Evo stuff around me.

If an Evo 7 in M class is less than a second ahead(I highly doubt he has less than 180rwkw either), I can't see big value in spending 10-15k on top of my Silvia sale to buy one... I will go 1s faster just by not using shagged tyres, 

Just gonna keep smashing this CA around, seems quick enough for Club level shenanigans. 

The "issue" will be that I'd like to do a Clubsprint WTAC event, but those cars are next level. Not willing to sell GT-R yet, so I will just sit on everything I have for now. 

Plus I am working on a game changing project on the side that will shave off BULK time. Like maybe a tenth lol

Make it 10k then, not getting into a decent 7,8,9 for less than 15. Can't see 10k in additional lap time really. 

Plus this thing is just too fun to drive and there are more people that need to learn about CA greatness.

(Bet it spins a bloody bearing on the next outing now lol)

Also, that Red one was 25k more...

Cool, so I can spend 15k on a Stock 7 with a cage, and go about the same speed? Sounds sick :D

Makes a lot of sense if I wanted an awesome daily/track hybrid, but when I have a car already (worth nothing re-sale wise) might as well stick with that if it's already as quick as a stock Evo for far less dollarydoos.

Gotta save my pennies because GT-R ownership is expensive ;)

    • 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.
