Turbo Engine rebuild 20HC85

Pistons, con rods etc are obviously different but piston rings are the same as an efi if standard BHM1531, main bearings are the same BHM1153, Thrust washer again the same BHM1295, Con rod Bearing is BHM1505. Carb, efi and turbo engine blocks are the same, the only difference with a turbo engine is the return hole for the turbo drain. I got mine moved from the original engine put into an carb block. Rimmers did have standard piston rings on their website. I was lucky in buying an unused carb engine with new bearings in it and used those.
Although the conrod bearings have a different part number they were exactly the same as the carb ones after I had measured them. With your tolerances it would all depend on what needs to be done or if you're swopping things and how much is worn out.
Crank has a different part number for a turbo but the part number is only listing a set including bearings and dowel and not only the crank. Part number for the crank set is BHM1584 superceded by LFT10007, efi and carb is BHM1583/LFT10006.
Again I used the existing carb crank after measuring it as it was the same as the turbo crank, i'm guessing the part number difference is the con rod number being different to an efi/carb.
As always check first before buying but Piston rings at std https://rimmerbros.com/Item--i-BHM1531

bearings are showing for a Rover 200 etc so check first https://www.bing.com/aclk? ld=e82H3q7...e28fa7f54706fe

Rimmers have standard and plus 10 in bearings BHM1153 and BHM115310 if you put those into their website

Hello, After many years looking for a turbo engine in Spain, I finally found one from scrapping but when I disassembled it I found that it needed an almost complete reconstruction.
The engine has this reference: 20HC85

I removed the connecting rod bushings and it has a coppery color and the piston rings have a lot of gap.
Where can I find compression and oil piston rings and connecting rod bushings?

Another question I have is how can I know if the cylinders are in tolerance? What measures should I take?

I have a 1992 carb engine and a 1993 efi engine, the EFI engine is in very good condition and I will use some parts if I can't find new ones.
Is the crankshaft the same on all engines? the one on the turbo model has some worrying marks.

I have a thousand more doubts which I am investigating little by little and I will comment in this post those that I am not able to solve by myself.

Any advice and help is welcome, thank you very much
