    Here's a few pics of its current setup and some that others have taken. A couple are from santa pod and one from Brands Hatch with the old wheels and tyres. I've now changed to 16x8 7twenty wheels for road use. The old ones will be kept for track use.

    After the blue cars engine let go last Tuesday I used the red car at Brands instead. I wasn't expecting much but was amazed at just how well it handled. This is quit a heavy car and running standard suspension with tokico springs and US antiroll bars. The grip through the corners was immense and not far off the blue car. The auto box was interesting and stayed in 5th for pretty much the whole sessions so I ended up driving at the same speed on the straights and through the corners. Had great fun though and still lapped in 60 seconds according to my lap timer.

    Well done Jon (shame about the blue car's engine). I hope you lapped quicker than Matt and with your auto box EXTRA;)

    The blue car has had a good run and it will return but not for a little while.

    The red car will replace it for now. I’m taking it to spa on Thursday and probably Le Mans in July and Nürburgring in August.

    I've put a few thousand miles on this one now with all the trips mentioned above plus using the car as a daily run-around. There's still a few issues to work through but it's getting there. After the trip to Nurburgring and my laps of nordshleife in the 40c temperatures I realise I require better oil cooling. The factory water/oil cooler had to be replaced with a take off plate due to its location so I fitted a small 10 row cooler and remote filter. After a bit more research I find that to cool a 300hp engine AND not reduce the oil pressure to the engine, a 25 row cooler would be required. I have now replaced it with a 25 row mishimoto cooler in readiness for my next track day. I'm also planning on check the calibration of the factory zed oil pressure gauge with a mechanical test gauge and checking the engine against the FSM pressure readings. The reading in the FSM are 4.33psi at warm idle and 43psi at 3k revs. Seams quite low to me but falls well within the recommended 10psi per thousand revs.

    I've attached some recent picture and a video to keep this thread up to date.

    What should the Toyota engine be at?

    The psi figures above are what they should be. I’ll be checking the actual readings this week. I was worried about the oil pressure being until I looked in the FSM. I’m now pretty satisfied that my oil pressure isn’t low even without taking readings.
