Took the sil80 out to the local hill climb for a run sunday. Car decided it didn't want to make boost so just ran it like that and still managed a 1.04:52 and 6th outright. Had a chat with some people about about the issue and seems the wastegate is getting stuck open so pulled it apart and found a few areas were marked on the valve shaft so cleaned it and linished the the shaft put it back on and everything seems fine now. Booked King of QR in September and will start getting it ready for e85 and retune in the next few weeks.

Good result, a set of headers really help. Its amazing how much they pick up

Welcome, there are a few z/v/g chassis owners lurking. Post up some more pictures and mods in the build threads.

Mca? Have rebuilt stuff in the past

That's a solid effort, what's the next event you got planned?

Was a good event, what time did you finish with?

Definitely have a go, didn't take long.

Got the sides done but need to get a a slide hammer to do the bottom. They are pretty thin metal, surprised the ghetto setup worked

More progress Found more damage around drivers side footwell, reckon the wheel has been pushed up there at one point and some rust on the seams but all fixable Had a go at trying to straighten the rails where they have been hit Planned most of the new engine loom and moving to the body. Going to use factory light and wiper switches and add a panel for every thing else.

Been nothing happening for a while as got the sil80 going and been trying to decide what direction to go but have been doing the important things like painting cam cover and making heat shield for the turbo. Fitted some more lights to the work area in the shed and converted to LEDs. Heaps better with the extra lights. Pulled out the ecu and loom this week to start planning a new loom with extra sensors and inputs. Considering going DBW as liking it on the other car. So will have to send ecu back to link for modding. Car is booked in to get the engine bay and under side blasted end of July so have to get a move on stripping.

there was a thread on NS around 2013/2014 on titanium retainers cracking was likely quality and how they were being used that caused the problems.

CIG locker cheapest way for 2 wheel skids

^^^ or coil, bad grounds, alternator output voltage. Its an electrical issue, resistance increases with heat. Get a multimeter and start testing. Is this on a factory ecu?

friend did it with ls3 and blower was great but killed axels. Z's need a bit more go and they would be perfect. new kit out that allows use of cd00* gearbox https://www.lojkits.com/collections/nissan-350z-z33-engine-swap-kits

Welcome, Still got the black 180sx from NS days?

A few cans of brake clean and tubes of rtv be all good again 😁

Can hiflow the turbo, mod the actuator rod to be able to adjust the tension and then run a 3 or 4 port solenoid. Rules change generally every 2-3 years.

nice, did it drive on there?

Idle control doesn't sound to be wired to ignition 12v. Find the it and wire to ign on 12v source or Link G4X & DBW no more idle problems

Classic GT is going to be full of ls2 and sequential gearbox equipped Holden's over the next few events. Be cool to see more skylines/80 & 90s Japanese stuff at targa events.

So far done v8 sprint last year (5x 20min), around 1000km Street driving and this sprint day. Most people I know who run them get at least a year of sprint racing and consistent to the end. Medium compound @Dose Pipe Sutututu will do. Got to get a new alternator as drops voltage in hot weather and when all the fans and lights are on.

$2400 255/40/17 Every event I generally go to slicks would put me in open/formula classes. Would like to have a go one day with some. What slick are you going to go?

Raced the car over the weekend, put the advan a050 on & got a wheel alignment friday. Did some logging on the way out to the track and was having weired issues with it hitting a MAP Limit randomly under load. Round 1 kept hitting a limiter at different loads and then lost all positve manifold pressure. Checked all the intercooler pipes and nothing wrong so pulled all the pipes and checked to see if BOV was stuck open but it was fine. Ended up pulling the external gate, stripping & inspecting it. Found nothing wrong so assembled it all started up and went for a quick drive and had boost again. To be safe I zeroed the wastegate table above 3500rpm and did the next session and no issues so random. Car was perfect after that and ended up going 47.45 Finished 1st in class and tied 4th outright was beaten by rcr skeleton, BMW M3 race car, 400kw WRX and 600hp LS ae86. The adavns are still the best tyre I have used and won't be going back to the nankang. Throttle blip was good for 2 corners and added another 5%. Need to do an oil change & bolt check will be sorted for another event. Should also look at a new clutch as was slipping towards the end of the day. Really want to put the fixed back seat in so I'm not sliding around......

My motor (rb25) has been reliable for the 10years I've had it (Built by Red R Racing in early 2010 by previous owner)I replaced the head with a ported one and did new gasket & studs in 2015, 260-350kw, Lots of track days(drift, sprints & hill climbs), street driving and shenanigans. Run on 98 & e85, sensible timing map, maintained it correctly, Good quality & thought out oil breather setup and not bang them off limiter. Like anything have a sensible goal & maintain it correctly will last a long time. People with efame only show the dyno runs & the one time they go to powerskids/roll race they don't tell you it failed after one day of being thrashed and banged off limiter. if building a competitive race car/motor they are always pulled & inspected and parts replaced at service intervals as per an engine builders specs.

Long time since no posts but if anyone is interested local club is holding a sprint event this weekend 12 June 2021 at the DriveIT facility https://www.facebook.com/MarqueSportsCarRegisterNQ
