No Crust Racing

Hmm not sure about idling oil pressure actually. What's healthy?

Oh I don't think the line failed because of the motor, it's just old and I also had an off track excursion to avoid hitting someone which may be related. Wanting to fix leaks was not about the engine failing it was more about the fact that my car is dropping gearbox and engine oil onto a race surface. I've had a couple of coolant hose leaks along the way and been lucky that I could get to them at the track. There's a bunch of coolant and vacuum lines under the plenum that are impossible to get to with the engine in the car and the manifold attached to the Head.

A decent tilt trailer is 3-5k. Borrowing the neighbors costs me $40-50. At the local track here's a spot to get it on and off without the extra ramps. Reckon I can hold out a bit longer while I'm still able bodied lol

In use. Best to have a spotter but I've done it myself a few times.

CA powered car, original bottom end, but with fresh headgasket and ARP studs. 143ks, and still has fairly decent compression 155-160 cold (new is 172) though as with all Nissan's it likes to pressurise the sump - I run dual catch cans to help this, top and and bottom end vented to atmo separately via baffled cans. Intake and exhaust manifold gaskets also fresh, a few seals been replaced around the place also, rockers, half moons etc, but some things still leak. At the last event for the year, it blew a coolant line to the turbo and drained the radiator, no big deal as I was planning on changing out the T28 BB and going E85 on an externally gated GTX2860R and some 256 cams anyway (Just acquired the cams and already have the turbo). Still need external gate, injectors and to modify the manifold to take it all (turbo is T3 and vband rear so will need different manifold flange, dump, and intake). Given I will be removing the manifold anyway, I considered removing the engine to replace the 28yr old hoses all over the place that are difficukt to get to otherwise and tidy up some of the loom/connectors which are also a bit worse for wear (race tape holding them on etc). Engine also has minor front crank, and rear main seal leak - though I did replace the rear main when I did I the clutch, so could actually be higher up on the back of the motor as the half moons are notorious for leaking even though they are new, as are the rocker gaskets. Oh, also has a small weep from the speedo sensor on the box where the mounting surface was scored, has new extension housing seal but also appears to be maybe leaking from there, already has new upper seal around shifter etc and doesn't appear to be a breather issue. So now I'm tossing up what to do. 1: Continue with turbo swap and retune, do nothing else., drive til it dies, ignore leaks, do things after it's dead. 2: Continue with turbo swap but pull motor and put fresh hoses in, fix leaking front and rear seals, do what I can for connectors, new water pump and accessory belts and clean up anything else obvious (Car already has new timing belt). 3: Pull motor, do all of the above but also freshen up the bottom end, just a basic Spool forged kit or something, but that means new headgaset and full disassembly etc. The Nissan has been let out also. 4: Acquire decent second hand forged CA, they do turn up, freshen up anything needed (I just mean seals/belts), put back in with new turbo setup, sell old motor running. 5: Pull motor, replace with freshened up or 2nd hand forged SR (probably blacktop for the VCT and being newer sensors). Probably wouldn't bother going through the hassle of a swap for a stock SR. This would mean buying different cams, ECU swap, different radiator, wiring work, better coilpacks (I have splitfires for the CA), dick around with cluster, change bell housing, not sure about clutch etc etc. Sell current motor running and all my CA shit. The CA has been good to me and keeps me in a class I can be competitive in, but she is getting on in age and the boys and I are considering trying to do 5 rounds of a series next year, I'm thinking about what I can do in the off season to make next year easier. I am a jew on this car also (car is still 4 stud for example), the GT-R gets love and $$, The Sil makes do with second hand parts, shit from other silvia's/skylines a upgrades and DIY shenanigans Kinda leaning towards 2 or 4. Though the extra mid range torque and response of the bigger SR would be great for track work - even if they do sound like shit and that's not up for debate.

Tell'em the cost son

Is this a Mustang build thread now?

f**king lol Haven't done many track days have you buddy. All good, keep building because I like where this s15 is going. Even if you are in drugs xox

You're not one of those guys who hates on everything just to be different and edgy are you... Do you tend to love a band until they make a hit song and appear on commercial radio? We've never shared a slab so I dunno the cut of your jib..

f**k you guys talk some shit lol

I kind of want to paint it the same colour as the GT-R =\

You got a thing for slow Silvia's or something

Footage from yesterday is useless as I accidentally aimed the GoPro at the revision mirror so that takes up most of the frame, as does my serious expression. Quality is good though so I'm happy with the new camera setup. Wouldn't mind a better GPS as there's some syncing issues with my older 5hz model. Anyway, shaved off 2 tenths from the PB and had a class win, won a shirt. That's 3 from 3. Was a very mixed day with rain all over the place as some interesting groupings (I almost hit 1 guy a few times as he just wasn't watching his mirrors). First session was wet and the car misfired like a bitch, almost rear ended someone and drove off track to avoid, good times. Coulnd't find the cause of the misfire, but removed and reseated all connections, checked all hoses etc and it just went away 0_0 Second session was dry and clear track so that was the PB. 3rd session I almost hit people again and never got a clean lap then the coolant line to the turbo broke away from the fitting and I couldn't be assed trying to fix it given I was confident the time would be enough and the rain kept coming and going. Was expecting more from the AR1s, they are wider and softer than the RS-R. I can see in my footage there's time to be had though so I'm confident I'll go faster on them next year, but by that stage I'll have replaced this turbo so it'll be impossible to tell. I think I ran them too low, about 34psi hot. They seem to want higher pressures but I didn't get a chance to test, also firmer damper settings than I normally run. Was yet another great day out and a good result for the little CA that can

Flares gave me clearance for 255s, stickers will slow me down because the CA can't handle that extra weight

I've got so many left over stickers from purchases that never get used. Just tell me what you want fam, Aeroflow? Moroso? Kelford Cams?

Only minor PB improvement which was disappointing as they are wider and supposedly sticker. This is compared to 6yr old thrased 235 RS-R. However, first session was wet, car had misfire, second session was dry and i shaved off some tenths on the PB without thinking I was going that fast, 3rd session I made a camber/damper adjustment which felt probably better in some ways, worse in others, but got held up in traffic on each hot lap then busted the car (minor). There's definitely more in it, but I was not immediately blown away. I also think I made the mistake of running too low hot pressures, around 34ish. They also seem like to firmer damper settings. Can see the driver side cops it worse at this track, anti-clockwise with a highish speed continuous right hander. I feel like I could have done the same thing on 255 RS-RR, which will last longer and cost less. It was also a hotter day than my last PB, despite rain it was still 30 degrees. Wont get another go til next year and by then will have made other changes to the car. Will aim for higher hot temps. Dirt on the outside is from driving onto grass to load car.

Nice gear! Surge tank is porn. "plenty of GTR owners will be begging for mercy as I pass them full noise sideways through 3rd gear sweepers, snapping into 4th spitting flames" Maybe basic bolt on GT-Rs? Anything with the same level of mods as your car, when it's finished, wouldn't be giving any f**ks about a SR powered Silvia with an old GT turbo lol What are you gonna do when you finally buy your GT-R and you get chopped by absolutely everything all the time and everywhere 0_0

I would've said 235 and 255 are more common performance tyre sizes and prices often reflect that. Either way, as long as you got what you needed for a good price

245 is an awkward and expensive size. I got full set of 255 17s for 720 I think.

I got mine here. https://www.facebook.com/Autosport-Tyre-World-717323221642985/

Obvious slip when too hot?

OK see how we go. Hoping the track temps don't chew up the compound too quickly.

Oh the irony. Old dinosaur turbo over here. Hah, Look at how many religious dudes voted no for SSM that love cock. Why do you think someone's actual choices will line up with the opinion they push on others? Fatz, will be a very good comparison - Looking forward to it.

When you get the new thing installed, take Baked for another ride so we can get another Haiku about how the cherry blossoms bloomed as it came onto boost and the buttery smoothness of the shift action as the billet components perfectly meshed to deliver over almost 400kW of JDM goodness to Sydney's mean streets.

First time using my AR1 this weekend, did we work out what the best starting pressure was? Gonna be a 30deg day
