normally when the a20nft is mentioned it refers to the astra J vxr VVT engine

 

But from your photos it is a late spec B207 engine

 

I wonder if you have a GEN 3 block :D

Take the head off and see if it's reinforced. Mhh...

A "Gen 3" has reinforced cilinder walls and a sandcast block.

This surface finish does not look like sandcast:

Very curious what pistons etc. this A20NFT block has fitted. And what code is stamped into the oil filter housing?

the block in TFD's photos is a GEN 2, the A20NFT vvt engine block is cast different and has no blanking plugs below the exhaust

The 'real' A20NFT also has a different coolant cross-over pipe and thermostat housing to accommodate the K04 turbo gubbins.. I think GM have sticker issues.

Take the head off TFD.

We need to know if Saab bodged their head on an NFT, or if we are looking at sticker creativity.

The 'NFT' and 'NHT' tags are slightly interchangeable in Europe it seems. The NHT is the Gen 2 bottom end (same as B207 really, and the older LNF engine used in the US) but will have different pistons and a lower CR (9.2:1) than the B207, and I don't think its any stronger than the B207.

 

If you had a borescope, you could eyeball the pistons through the sparkplug hole and see if its fitted with the direct injection pistons. I strongly doubt it will be though, and if it was I'd be sending it back!

Reply from Neo Brothers: Hi there, Thank you for your email, the engines are the same and the different coding is just internal information from Saab. You wont have any issues with the fitment of this engine. ------------- I have a borescoop and will check some numbers on the block this week.

That's just a standard B207 piston. The 'real' A20NFT pistons have a little bowl in the top to aid fuel dispersal from the direct injector: https://www.cobaltss...zpsawjmqxvn.jpg

Ordered from Neos Thursday. Delivered Friday.

 

Stripped on Saturday (with head on the kitchen table for some ex. port tickling - don't say it)

 

As above, I can confirm the supplied 'A20NFT' engines (mine had the same stickers as TFD) are just B207 engines (Gen 2 blocks / pistons etc.). The ID markings on the oil filter also have 'B207' and 'A20NFT' marked on them.

Hi, sorry for resurrecting this old thread but I have am 2012 Astra PJ OPC that has had engine failure and am trying to obtain a new engine, the A20NFT, but there seems to be 3 different power specs that get listed for the engine.

Are they all the same engine, except tuned differently?
For example, if I got the engine for the Saab which I think is 166KW, can I configure it to be 206KW instead? Or do they have a different turbo, pistons etc?

Any help would be great. I'm in Australia and sourcing a replacement engine is being a nightmare and it looks like my only chance is importing one myself from Europe.
