The plan is to get it out of the shed. The reality may fall some way short. But hope is as cheap as despair as they say. Will go a wide band I think. The coils are ok so maybe I’ll miss the $1500 on the R35 coils etc. Im still on the fence about a trigger kit. The HKS one looks nice ($1k) - not sure how it works with the Link or if Link prefer something else. Oil pressure is fine so I’m not that concerned there. Fuel pressure I’ll have a think about. The IAT got changed for the Link anyway as the old RB26 ones were really slow reacting and pretty poor. The Power FC just worked. Wasn’t terribly refined but it just worked. Probably made a mistake replacing it really. E85 isn’t available locally - it is 100+ kms away which puts it in the too hard basket. Lastly I understand Tunecorp in Perth are pretty good so was probably going there. As for turbos is there are new age -5 drop in replacement? Turbos have come a long way in 20 years, everyone is big single which is fair enough but I prefer the old school complication of twins. Wasn’t chasing more power (well, not much more) but more efficiency would be ok. -
I thought I'd share this....the shell is non genuine but they found or built a lot of the genuine parts. Plus, it is by far the best colour scheme of those years, the winfield once was particularly shit https://www.v8sleuth.com.au/written-off-inaugural-godzilla-recreated/ -
Good work Pete and glad the car held up well....been a while since I've seen you try properly

Just quick update, I've had tech issues and so a backlog on life stuff....I will pull lap times from the video and data from the ECU logs to do a proper update. But basically, in order of importance: 1. The car was excellent fun on the track, really felt a lot like the good old days. And nice to have AC while waiting 2. Coolant got really hot; again I need to pull and analyse the logs but the standard system is not up to tracking at 30o+ days, once the system was heat soaked after the first 2x15min sessions I could only do 3 laps before it got 110+ and I had to cool down. If I can't improve that it is a deal breaker 3 Oil temps were fine all day, noting it was short sessions due to 2. I think it will likely need work 4 Biggest surprise AT temps were fine, never went over 100, I would have been OK with 120 before I was too concerned. The auto sucks compared to a manual (of course) but it is faster to launch and I just need to downshift it manually before hitting the throttle, then it was OK. When I post the vids you'll hear it telling me off (beeping) for trying to downshift too early (it needs about 3500 before it will downshift, depending on gear a little but we are mostly talking 3/2 and 4/3) 5 A052s were not great which hurt the lap times, but I will be constrained in what I can get in good tyres that fit the wheel wells. These were small for a heavy car at 235/45/18. In theory I can fit 9.5 on front and 10.5 rear (so not square) but I still need 670mm+ high tyres in good brands. 6 Standard shocks/springs/roll bar are too soft for track work (of course), but that was always on the list. And happily, no white on the mat, despite having a teenaged passenger, extinguisher mount was fine. Also, it was nice to have Wakefield Park back in action . Because the car was so quiet it is eligible for Green Day, which I thought was a band but is apparently a series of cheaper practice days they run with a lower sound limit, that is a smart idea.

Great to hear you are bringing it out of the shed again. Unless you have specific issues I'd just add the wideband, get a good tune and enjoy it. Certainly no point changing coils etc if they are working. If would add fuel pressure and e85 sensor if you are doing a general update but not if it runs OK and you are just getting it back on track. The other thing is smaller, modern twins, -5 are OK for motorsport but pretty laggy and old tech for street use (of course, if performance is the priority a modern single with twin scroll manifold etc is the go but not cheap). The final thing worth considering is switching to an ethrottle if drivability is still an issue, it should make things a lot simpler and smoother
