Its great to see you are getting such a solid run with the car. As its coming into Winter (winter is coming..) is it making a difference with the intercooling as its water to air?
Have you been checking tyre pressures (at the track) for the Nittos?

Hey Steve, I'll know more on the first point on the 9th of June :-) but I think it will tend to plateau at some margin above ambient, approx 15 degrees above. Not sure if intake temps of 30 or 45 degrees make much difference?
 
Tyres I've been going out 27-28 psi and coming in 32 hot, they seem pretty hot and sticky to me but you know I don't push as hard as some ;-)

I think the lower the temp the better for insurance and performance. I think the 3SGTE cannot manage the higher temps as well as other engines due to design but don't quote me on that one.
As for tyres, push till they turn to mush!!

Just a few updates. Had another trackday at SMSP (GP circuit) in September, knocked the PB down to 1;55.31.
November: New windscreen, wheel bearings, rotors machined and project mu 800 pads up front.
Took the car down to Wakefield last week, had a great day with nice weather, only 30 cars max, so got in a whopping 84 laps and smashed my PB from 1:13.45 down to 1:11.05!
Might have had better still in me for the late, cooler session except the intercooler cracked a weld open so had to call it for the day. Apart from that the car has been really solid and well balanced, no psycho rear end antics like the early days.

So it’s been a long time between updates, so I’ll make it a good one! After seemingly years of endless turbo-life dramas I finally bit the bullet and committed to a 2GR-FZE swap. That’s the TRD Aurion supercharged 3.5l v6, with the 1320 supercharger. I really wanted to get some “reliable racing” into my future, and I’d been very impressed with Eric’s car at the Wakefield Challenge. The torque and the noise were both very impressive, and I did feel like I wanted more than the NA 2GR had to offer (without a lot of work).
 
Not being any use with tools, Charlie Bianco in Melbourne coordinated everything including purchase of the 90k-odd km motor, on-sell of all the useful 3S-GTE bits, and so on. Under Charlie’s direction Nathan Appel has been hands on with much of the spanner work, Curt Ford did the exhaust fabrication work, and CMS Performance did the water-meth injection control and ECU hack/tune.
 
One of the things I really wanted to measure was the impact of the water-meth injection. It made a lot of sense in theory (charge cooling effect = air density & more power, anti-detonation effect = more timing and more power) but I couldn’t find much evidence for it or before/after results (at least with the factory ECU).
 
As a result of the ECU hack & tuning work plus water/meth, the car has been reliably putting out a good 215 rwkw without any heat soak or timing, vs around 195 (from memory) before.
 
Aside from the swap and water injection, Charlie has given me a longer final drive ratio and I’m happy with the result on both the highway and the track. Sump is baffled for track reliability.
 
Time to race, and places to do so with Wakefield closed lately :-( have seen me doing less driving lately, but something I’m keen to change this year.
Overall, the car is great to drive and sounds awesome. Has plenty of grunt and pickup. There are a few clips on youtube for you to enjoy:

Exhaust sound & 2nd gear pull https://youtu.be/Vr6RS36B_3A
Am hoping I can get myself organised to come along to some MR2 / Toymods events this year.

Congrats on making the move to the SC 2GRFE. Looks like a great set up. Car looks really quick of the corner.
