Default How to tell if the type of engine a 991.1 has?

How does one find out if an engine is G series or not and if its G1 vs G2?

Engine serial number. You can find it on the sticker on the inseide of the engine hood. It starts with the manufacturing year (E = 2014, F = 2015, G = 2016). The updated G engines have a "6" as the first of the digits behind the letter.

Long and short as I heard:

E0 - recalled due to rod bolt issue
E1- replacement engine for above, but had issues where some cars would score their cams and develop a misfire at high rpms
F - Same issues as above, meant to have some oiling changes but not seen any hard and fast details
G - Rare late engine, largely fine but not immune to the issues.

I went with a E based car (swapped to E1), I've got 6 years to put miles on it and discover if it's a duff one.

Noob question,-- so if your engine has been replaced, I would assume they (should have) put a new serial number sticker on it?

Model Year allway starts in the middle of the year before. So a GT3 produced in 08/2013 is MY 2014 = E.

F - Same issues as above, meant to have some oiling changes but not seen any hard and fast details ----- F Engines until Engine Number F 03047 have the same party than E engines; from F 03048 they have optimized parts in the top end
G - Rare late engine, largely fine but not immune to the issues. --- the first 'G' are rare but they changed some things during production, thats the G06 engine than and widely spread (all the current replacements are G06). Basically same engine as RS except displacement

Bringing this old thread back. Looking at an 14' GT3. How to tell what engine it has? If I interpret it correctly it's an E engine? E1 or E0?

This picture was taken from the engine cover.

10th digit of VIN, no?

Will have E, F, G listed.
Not sure if the VIN will decide G1 vs G2, etc.

This was engine VIN. So from my research it looks like it's an E engine but not sure if it's E0 or E1. I'm guessing it's E1.

Every 2014 GT3 had the engine replaced.
So it should be at least the E1 engine.

Yep - I had an Oct 2015 G series engine in my Jan 2016 GT3RS when it seized at 43000 km - PAG replaced it with a new H series engine - I think these are quite rare as they were only installed in a handful of 2017 cars - have done 31000 km on the new engine (yes - this chassis has done 74000 km) - track and hills/canyons - hasn't missed a beat and it gets a very good workout at the track once a month - uses very very little oil - about 100 ml every 5000 km - I love this sucker :-)
