No Crust Racing

Starting a business he tells me.

Haha very cool, I can see how you could catch people napping in that.

Looks good

GoPro footage thanks.

I bet this is like the people who say they chop this or chop that and the other car isn't actually aware of there even being any "race" lol I want a Tesla though...

A bit of stuffing around with harness lengths and the inner eye bolt position on the inner mount but got there in the end. The side holes are smaller on this seat and don't allow the buckle to fit through the hole nicely which is an issue as the lower strap portion is too long and sits too close to the eye bolt to be tightened safely on the inner. I ended up having to mount the eye bolt further forward and on the seat mount itself rather than the rail. It seams to snug up nicely but we'll see how it goes at the track. Sits a bit higher than I'd like but I sit high in a seat compared to mates, should be fine for the missus, will test later. Total weight is approx 13kg vs say 20-22kg or so that the Falcon's Autobarn buckets are.

Do it, Gains are proven, nothing to lose. Helps prevent surge. Especially important if chasing any remotely decent power with twins. Or don't do it, but go single instead.

I didn't like the idea of drilling the hub, plus I wasn't see 350z calipers coming up much, and when they did, seemed expensive.

Ahh I knew about the fronts I meant the rears. I don't run a hand brake at all currently, though I may go to a basic inline hydro.

Yep for the Sil, I already have a BM50 and just a line split and it's never leaked or caused issues. Jury is out on whether 57 is even required. I don't need my brakes to be ultra sensitive as I heel toe and like a progressive pedal. If I recall correctly, rear Brembo's don't bolt on directly? But I have read so much shit and can't remember now. I was looking at Evo up front as I could grab some calipers, adapters, pads and rotors for $600 - just the 320mm rotors. They seem to be consistently cheaper than GT-R Brembos and look to be a better caliper with a bigger pad area. I'm too caught up in the engine build at the moment anyway. Do GT-R rears go straight on? Would be nice to have a direct bolt on option, no adapters etc.

Bit more than 1-2k really given some of the quotes I've had (though they include assembling/clearancing the head, all machine work etc). The only person who's jumped out at me so far as having genuine SR20 Circuit experience (rather than street/drag focused) is DM Motorsport, the one who owns that SuperGT S15. He claims to have acquired the testing data for SR20 race engines with the car and a few other insider secrets. He has shared a few things so far that line up well with some of my own research into weaknesses/how to avoid etc but he is far from cheap and he's in Sydney. He's given me a reference, but as with any business, I'm sure that reference will only have good things to say. Sump is here. Got the aeroflow one, plenty of capacity, trap doors etc.

I'm still trying to get some objective reviews. It's difficult as nobody locally specialises in SR20 and that makes it hard to walk into a workshop and get a feel for the place. I'm also keeping in mind I'd always wanted to do it myself, with assistance from a meticulous mate of mine who builds motors as part of his work (albeit diesel), but the cost of getting it wrong adds up quickly. I realise there's rarely, if ever, a warranty on a built motor though.

Things starting to trickle in.

When I saw it start heading to wards the wall I feared the worst for you lol Good job to stay off the armco

*flex*

Good luck

AAC was my high idle issue back in the day of 33 ownership, super common. Cleaned it recently?

I just bought that rail for my passenger side. Seat looks great.

Attended Wilby Motorsport Park for Round 4 of our series, round 5 is also there in 6wks or so. It's a very short course with laps ranging from 32-40sec. It's a bit agricultural, but the vibe is fairly relaxed. I went on my old 235 RS-Rs to see if I could have a class win on those and save the AR1s. I forgot to turn the camera on which is shame as I almost died a number of times in that first session, to be fair it was cold but my god the lack of grip was hilarious - did a 37.7 or so and was .7sec behind the class leader and not overly confident I would catch him - swapped back to the AR1s after the first session. Ran a 36 flat in S2 then squeezed a few more tenths out of it to run 35.7 in S3 which was good enough fro a class win and a top 10 outright finish. Sat out S4 as the 2nd place car had mechanical issues after running a mid 36 and 3rd was too far away to catch me - was nice to pack up and be home earlier. Tried a new breather setup which looks like a hot mess due to piping length etc, but is finally keeping oil in the car with only minimal oil accumulating on the lip above the firewall from the breather. It's now 2 stage with rockers/balance pipe all Tee'd and into 1 port on a baffled can with sump drain, outlet from that can feeds another baffled can with an filter to Atmo. I now have the rev limit warning set 6700 rpm as torque starts falling away then anyway and it limits how much oil is being pumped to the head. Oil surge is still evident on quick direction changes, but I'm guessing it's always had it. If I manage to win the remaining 3 rounds I'lk have had 10 straight wins in my class, which will be a fitting send off for the CA, if it doesn't die first. Bought a balancer for the SR and have been looking at clutches and manifolds - went ATI in the end. Was told my shipment of the main group of parts (pistons, rods, head gear, studs etc etc) is just about ready to ship and my head studs were just picked up from Mazworks - they're only ARP, but apparently they have a custom length that bottoms out properly that people swear by so I grabbed those. Started test fitting the passenger seat, just need a few locking nuts etc. As always, here's a hotlap in 1080p and 60fps including a little B roll footage.

I'm building an SR20, DM is one of the places I've talked to and as his focus is on circuit racing engines, rather than street/drag like a lot of other workshops I am interested in potentially using him to do the bottom end rather than doing it myself with a friend who's an engine builder by trade, but not experienced with SRs. He's mentioned he has Nismo internal testing data from the Super GT cars, and as he has one of them (an S15) and appears to be in the high end circuit space it all seems to check out. As it's not a cheap decision and I'm not local to him I was hoping to hear from anyone who's had experience with him. https://www.facebook.com/dmmsydney/

I meant what they were unhappy about. Less braking power/too heavy/too expensive for the gain etc

Going back why?

Much obliged. And good timing too because I have got some tasty parts arriving for this new engine

Oh same for me, I will run them til they are absolutely dead. I'm switching to some old RS-Rs for my next round to save the AR1 for the faster tracks.
