Hi All
 
Well not a great amount of progress but I thought I would take advantage of the good Aus dollar a few weeks back and splash out on some bits for the engine rebuild. These arrived this week.
Decided on some JE forged 11:1 85.5mm pistons and the suited 5.483" Eagle rods which are used on the Blacktop in the US market. I have the Silvertop but as both variants share the same bore and crank these will provide an improved crank ratio - albeit by a small amount
Pistons look nice with a big dome and large valve reliefs. Rods are H beam items with ARP2000 3/8 rod bolts.

Paul, Have you done a static compression measurement yet? Not sure what it will be like with your silver top but the advertised ratio compared to reality is quite different....

It may be your concern... I think you'll be way over what you are chasing...
I will what to hear when you measure it...

The advertised compression was well under what we got when working mine out.
I grabbed the 9.0's as I am going turbo. Turns out I have to run a really thick head gasket to get it down to 9.0.
I can't remember the finer details but I used to have a set of 11.0's which when worked out, it as over 12.0.
Thats the short story....

No worries. Can't wait for you to get it on the road. 

OK, as I need to remove the engine to continue the body work I need to complete the gearbox mounts. I purchased a replacement Celica gearbox mount as the original was shagged and then had a think about how I would do it to retain an OEM appearance.
So, A little time measuring and then draw them up in Solidworks to produce a flattened out template to transfer to the 1.2mm plate. These were then bent up at work and should do the job (see below).
They will be plug welded to the floor pan with the verticle section extending up into the tunned and welded to provide additional strength. The cross member will bolt to the longer horizontal surface of the mount and this will give me the room required to remove the gearbox if required in the future.
A "floating" tapped plate will be installed prior to welding in place which the cross member will bolt too through the new boxed mounts - similar to the principle used for the door hinges to allow adjustment.
I will rivet temporarily in place so i can measure and bend up the cross member.
 

No, that's not route I plan to take.
 
The 11:1 is with the following:
48cc chamber
0.25mm deck height
1mm gasket
85.5mm bore
87mm head gasket bore.
I have a program and punching those in gives me 11.03:1 CR
 
I will wait and see how it all unfolds.

Because I have been down the track with these pistons before.
