I can report that my home made pressurised overflow cooling system works a treat. No more overheating issues. Lew's loan motor also worked well. Given we seemed to have finally sorted out the cooling issues, it appeared to be time to finally build a proper motor for the car. After nearly 10 years of running essentially stock 1Js, I have committed to building a motor.
The last six months have involved purchasing all the bits and pieces to put the 'good' motor back together. After talking to Chris at C & M Engine services not far from my place I reluctantly handed over my good block and a couple thousand dollars worth of ARP bolts, bearings, rings, cams, springs and all the oil protection gear. When I say reluctantly, this is no reflection on Chris - he was more than happy to talk me through the finer points of a high end engine rebuild, and do the machining work etc. It was my wife who finally said "How much extra is it if you just get Chris to put it together?". Turns out this was a good question, not because it was cheap, but because he did things to my motor I would never have picked up.
I'll post up some details about the block work later, but suffice to say every surface that could be honed, bored, machined, or surfaced has been done. Bolts got pre stretched, measured, stretched again and measured again before Chris would allow then into the motor. We ran into some problems with the dual valve springs sold by a well known JZ expert - that is they dont fit without some serious machining, and even then the fit would not be something the engine builder would be happy to warrantee. The right springs were purchased direct from the manufacturer and went in.
