Wow, this is sexy

[hachiroll]

Thanks...

How can I remove pistons from connecting rods?

[hachiroll]

ebay rebuild kit including 81.50mm NPR pistons, NPR piston rings and standard KING bearings arrived. gaskets, water and oil pump are from EVERGREEN, tensioner is made by QUEEN JEN auto parts

please let me know what you think is usable for stock engine from this kit. thanks

and also plastigauge from UK

Should all be good, I run the same pistons in my 4AGE, the alloy is sh** but does the job.
Exept for the headgasket, these are low comp pistons to compensate your compression loss, run the thinest headgasket you can get.

I´d let a GOOD engine rebuild shop change the pistons on your rods, they have the proper equipment to ensure the rods are not twisted, etc.

So the block, pistons, crankshaft, bearings and other stuff are in machine shop in Prague. One of the pistons had a pin stuck inside the piston. The machine shop called me today and said that the piston is shoddy (i dont know if its the appropriate term) but that they are going to be able to fix it by machining the piston and adding a snap ring to hold the pin. The conrods are also bend so they will also need some work. So be careful when buying NPR or NOA pistons, next time I will probably buy forged ones...

So the block is done. Job done by the machine shop:
-Conversion from pressed pins to floating pins as I wrote in previous post
conrods were twisted/bent so they were straightened
-Some basic porting job was done on some oil channels and other sharp remains from casting were canceled
-Block was bored to 81.5mm and honed
-Block surface where the head gasket comes was machined to make sure its 100%flat
-Bottom end was cleaned and assembled...

New parts used on the bottom end:

-81.5mm NOA pistons (I am interested how long will these last)
-NPR piston rings
-king bearings (standard size)

I did the same rebuild as you for my AE92 but i didn't bored the block.

Good luck with it

Can you please give me advice what head gasket should I use and where to buy it. I am unable to find headgasket for 81.50mm bore. Engine will be stock, maybe I will once use 256 degree camshaft. Head was grinded 0.3mm
Thanks
