    Lol equating brand differentiation with bravery is a new one lol. Hatches look fugly as, personal preference. A Renault will have substantially less local support in terms of parts/knowledge and likely cost more to mod. It seemingly offers no advantage over lots of other suggestions besides "bravery" and we don't mesure that at track days lol Considering S15/14 due to my Nissan knowldge and affiliation (2x GTRs 1x Skyline and 1x Silvia). Parts availability and price. Plenty to choose from. Better suspension and chassis than my S13 which still needs 5 stud and a proper cage and is a tired older car with an original motor and box. Oh and RWD (less understeer issues apparently) and weight advantage over Evo. I just need someone to throw me the keys to their Evo so I can go see what I think of it on the limit of grip.

    I think you missed my sarcasm. Also there should be pics of completed wiring, because that's very important to see.
  3. No Crust Racing
    I cannot believe you didn't update this thread with such epic news.
  4. No Crust Racing
    Ya'll African Americans honestly think he would "forget" to update the thread if there was a noteworthy update? I hope he sits on the final figure for ages and just posts a teaser vid of him driving it out of the shop or something. Having tuners/mechanics work on my cars has been an eye opener for me, I am much more patient now.

    My car cam with Tomei Expreme manifolds, which I removed when I went to -9s and I used N1 manifolds instead as they are cast (so no risk of cracks) and slightly larger than the stock manifolds, but not as big as the Tomei's. Best of both worlds. Don't port them for power, port them for response/smooth gas flow. As was said stock manifolds flow plenty for a -9 turbine housing.

    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

    Good points. I don't have a hoist (yet). I would likely buy a build/pretty much built on and a built Evo seems to command a premium vs built S15.
  8. No Crust Racing
    Complexity in terms of packaging also, removing box seems like a much bigger job (seems, i don't actually know). Everything appears more tightly packed in engine bay etc.

    Hatch enough for me... https://www.google.com.au/search?q=megane+RS&rlz=1C1CHFX_enAU687AU687&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjS8pbn3uvUAhWCmpQKHcNuC3cQ_AUICigB&biw=1920&bih=1070

    I see plenty of S chassis representation in my club. Nah don't need reason, genuinely interested in pro's and con's of both. I see far more Evo's putting down fast lap times vs Evo's at the top end of town (WTAC etc) but we're only talking clubsprint and state level comp here. The allure of AWD is definitely appealing, but the simplicity and lower costs of an S15 are good too, plus I'm very comfortable with Nissan in general in terms of service/repair. I think I lean towards an Evo, as the ultimate goal is lap time, but then I think I want to stay Nissan because I've always been Nissan and look at cars like the Scorch Racing S15 as inspiration. I like the challenge of RWD, but I'm not really into sliding around all over the place (hate drifting) and prefer the idea of power down and go. GT-R was so fun to track because it has grip for days even on shit tyres.

    No hatches plz.

    Common Emo faults? 6spd not great? Seen people needing to do SAYC "rebuilds" on E7s, but have no idea what that's a rebuild off (transfer case? centre diff? do they even have a centre diff?). How much weight can come out of them easily without going silly they are surprisingly heavy.
  13. No Crust Racing
    Hah what a great clip, you know they put always Tsuchiya in the fastest and best car The other two have much better aftermarket parts support, especially in WTAC formats. Parts more expensive for everything on a Golf. Plus it's a Golf... Weak boxes, weak bottom ends, shitful motor to work on, inferior AWD system. All track specific points, but that's the context of the discussion. I have never seen a WRX or STI go faster than anything else of similar mods, and in many cases lesser mods and less money spent. They suck. Any company that intentionally puts an untuned length manifold on a car to create a "unique" sound at the expense of torque/gas flow/heat build up is stupid.
  14. No Crust Racing
    They are cheap because they are shit. Have not seen ever seen a WRX come close to an equally modified Silvia. f**k I hate Subaru's.
  15. No Crust Racing
    That's one vote for "Other"
  16. No Crust Racing
    Good info, thanks. Coolant is an odd one, stuffed head gasket or bad thermostat etc? Just haven;'t seen that on CAs or SRs, normally it's oil because that's Nissan life.

    Remember PSI is just a pressure reading in the manifold and tells you nothing about the actual air flow being put out by the turbo/ingested by the engine. For safety sake, you will want to put it in a dyno at a bare minimum and not be getting into boost until you do. Make sure the AFRs are safe. As -9s are a step up in size compared to stock, they flow characteristics are quite different. Usually, people do turbos with an ECU/injectors/pump etc as you can't make good use of the turbos otherwise. Are the current turbos actually stuffed? Minor chips in blades is not a big eal at low boost and could allow you to get the other bits together and do it all at once properly.

    Mild or mildER? Comparison doesn't mean much without knowing specs of each car. IF they were same tyres, same power and nothing else largely different, then cool. Thoguh you'd want to factor in cost to switch to the Evo vs gain in lap time. If we're talking 300kw silvia's on semi's vs stock turbo evo's on good road tyres but still going faster, then damn

    Compressor map shows 22-psi is about max efficiency. https://turbochargerspecs.blogspot.com.au/2011/03/garrett-gt28r-gt2859r-56-trim-310-hp.html Approx 2.5 Pressure ratio on the graph. HOWEVER, people argue that the limiting factor to the turbo's longevity is actually the turbine flow/heat and as you can see from the graph, the turbine starts to choke before the compressor does. Choke = heat, heat = premature wear etc. So how hard you run them depends on the type of usage and your appetite for risk. 20psi should be fairly "safe" on both fronts, but 22-24psi squirts are not going to hurt a healthy turbo in a street application. Other variables come into play here also, fuel type use? E85 has lower EGTs = happier turbo. Size of dumps and exhaust? Bigger = more flow, less backpressure and less work for the turbo. Etc etc. We ran out of fuel pressure on the dyno at 373kw at 20psi on -9s in my car so this week we should see if it will happily hold 20-22psi. Keep in mind this is with N1 manifolds, 3" dumps into 3.5" exhaust, E85 and Kelford L182A cams (springs and head studs for insurance) with pods (proven to make more power at this boost on the dyno) and a Plazmaman intercooler. To run 20psi+ on these turbos you will also need fuel pump, injectors, an ECU to make use of it all, and quite likely AFMs if you stick with those rather than going MAP (which would also mean needing a MAP sensor).

    Goal would be lap times. Ideally a built car or something requiring minimal finish off, not a project build.
  21. No Crust Racing
    Budget includes acquiring the car. To be fair yopu can get this for $25k or less and it would be fairly capable. https://tracksales.com.au/browse/circuit/timeattack/2005-evo-9-track-day-car-554.html Same power would see S15 with better power/weight. Is Evo grip enough to make up for that I wonder.
  22. No Crust Racing
    S14-15 vs Evo 7-9 Track Car Let the shit talk begin. As a club level dedicated track car, which would you choose and why? Evo is well regarded as one of the best track platforms around, but Silvia's can hold their own as well. For arguments sake, limit the budget to 40k purchase/build price as this is Club level events we're talking (sprints, enduro's etc, not door to door racing). Silvia is lighter, less complexity in terms of drivetrain and electronics, cheaper most likely, and easier to work on at home maybe? Evo comes factory with TS turbo, has proven AWD platform, stronger motor and gearbox (5spd).

    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.

    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.
  25. No Crust Racing
    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.
