I am taking my R32 GTR Nismo diff, GTR water pump pulley with the Zed body out this Sat to Oran Park. As most know costs have gone up due to insurance etc, anyway they urgently need a few more to cover costs and run the event. It is the south circuit with time keepers etc. It is a supersprint. You will need to join a club and also have cams licence or join on day but need to register and pay ASAP. If interested contact me direct. Come try your GTR or GTS-T or anything else against the fat slot car zed. After all it is only a heavy slow zed and lots of other cars to time compete with.

    • If you go 2.8, you're going to want bigger turbos. Scratch that. If you go 2.8, you're going to want one single larger turbo.
    • Definitely the stroker kit. once you mention you have a RB28 everyone will assume you will flog them and hopefully won't start asking about support mods. Anyone will be too scared to race you, except maybe the RB30 boys
    • Just a quick update: I decided to go ahead with the de-cat for now. The exhaust shop inspected the catalytic converter and said it was in good condition. I took a look myself, and it does not appear broken nor clogged. After the de-cat, the car feels more responsive and smoother. The shop also reinstalled the exhaust temperature sensor into the de-cat pipe, and now the warning light no longer comes on, even when driving hard. The only thing that’s bugging me is the tinny, “can-like” sound the exhaust makes now (similar to having a hole in the muffler). The shop suggested that I might need to replace the muffler. I'll have to think on what to do next.  
    • I want to start upgrading but don't have the budget to drop 15k at once, if i was to do one first which would be better and why?
    • Yuh. It is very rare for a single turbo to throw ceramic into the engine. Quite common on GTRs. As I posted above. Mine did destroy the O2 sensor on the way out though! Plastic compressor is fine with the temperature. It's not some flimsy PE/PET/PP thermoplastic. It's a thermoset resin with reinforcing material in it (a composite, as posted by @Lithium above). The compressor never sees much more than 100°C because it's never boosting very high. If you boost it high enough to make a lot of temperature, then the turbine will depart the scene and stop the party anyway.
