Yeah same with Australia iirc. But here in the states and Canada they had the smaller tips for 13/14 MY and changed for 15MY

Hey Fellow FT86'rs,


With us being so involved with our platform I'd be curious if there is a laboratory we could send one of the new parts and an old part to have them analyzed and tested. Kind of like how other threads on our forum tests the different oils (Blackstone Laboratories). Though, it's nice to see the valves being updated; however, the rods in the short block could use some refinement.

After reading this entire thread, I'm still not certain of all of the exact changes (not just part number changes) between the 2013 FA20 motor and subsequent model year FA20's...is there any comprehensive list of internals and engine parts that were redesigned/upgraded since 2013?

Another reason for new part numbers is cost improvement. If they find a cheaper design that still meets minimum specifications that equals more profit and keeps cars affordable. In general you won't see many design improvements that are not related to cost avoidance. Either by correcting a design flaw or quality issue which helps avoid warranty replacement cost or find cheaper sources for parts which helps reduce total manufacturing cost.

No $$$ No

Some of the newer parts are not compatible with the older ones. You can find this if you use the Subaru parts tool. It looks that the FA20 engine was revised slightly, but this was not communicated by the factory.

I would assume the 2015 FA20DIT has different parts then the FA20 GT86 engine.
This entire post would be a little better with comparison part numbers and even better with measurements and pictures. When the FA20DIT was in R&D they may have located a new manufacture to supply valves cheaper.

Manufactures are always looking for cost savings for more profit.

Where these part numbers are pulled from in the OP I am unsure. I could look to see if they have been superseded. As mentioned above, new supplier, new coating, reengineered? Without comparing side by side its a guess.

If not backwards compatible I will guess FA20DIT WRX part VS FA20 BRZ/FRS part. Which still may be compatible but not according to Subaru

Edited, I am going to guess new source manufacture = new part number

Being compatible and being on an official build sheet at the factory are 2 different things.

Look at the Honda world B18C GSR cylinder head fits on a B16A but not according to Honda because its not an official build part for the factory or dealership replacement

I was more curious regarding the changes between USDM 2013 MY FA20 vs. the 2014 FA20 vs. the 2015 FA20, not so much the FA20DIT.

Yeah but when the FA20DIT came to be Subaru probably got competitive pricing from another valve manufacture, As I stated manufactures always looking for cost savings, new source for parts = new part number. I bet if you compare the parts side by side 2013 vs 2015 they are identical.

I work in the manufacturing world, source for 3rd party suppliers change all the time. You make a contract for 1 supplier when it is up you discuss pricing, or find a cheaper source with same quality.

Just like renting an apartment, landlord wants to raise the rent on lease renewal, move to a new place.
