86 parts compatibility
 

Does anyone know the compatibility of exhaust/intake parts between the current era FRS/BRZ and the 2017 86. I just picked up an 86 and I'm curious.

Thanks!

As far as I know everything should bolt up the same but i could be wrong.

I'm interested in that gauge cluster with all the power curve and temperatures etc.
I wonder if you can swap that

I think I heard there are slight changes in the exhaust manifold. I would think everything behind the cats is the same though.



I'm pretty sure @Zaku already has looked into this and determined that it would not be an easy job.

Intake box, filter, tube, and manifold have been revised. Exhaust manifold also revised. I would assume you could swap the intake system and exhaust manifold between the two, but someone needs to test it to confirm.

I read somewhere the flange on the header to the overpipe is slightly different. Intake and exhaust manifolds are definitely revised.

Going from the MY17 BRZ document that was posted up here somewhere, the engine changes are:
Increased cylinder block rigidity
Greater piston durability
Changed valve stem finish
Improved roughness of camshaft journals
Optimized fuel pump drive cam
Optimized internal shape of rocker arm pivots
Changed shape of fuel system components
Changed fuel pressure sensor
Upgraded to next-generation fuel pump
Changed shape and material of intake manifold
Optimized flow channels of air intake system
Changed specifications of air cleaner element
Changed shape of EPF (Exhaust Manifold)
Changed material of EPC-R (Front Pipe)
Changed material and shape of exhaust pipe system
Changed specifications of cam angle sensor plate
Changed ECU hardware
Changed engine harness
Changed material of oil spacer
Changed specifications of alternator
Installed new battery condition sensor
Changed specifications of crank angle sensor
Changed shape of crank angle sensor plate
Changed diagnostic specifications of O2 sensor

So no, not many changes. My interested to see the intake system and exhaust manifold changes, both will probably end up being cheap to buy from those that replace them and might see some benefit. Also would like to see what change in O2 sensor, have they gone for a true WBO2 like many others do these days, or just changed the logic in the ECU?

Also the power curve is just a stationary image and not a real time 'dyno'

Have any of the tune companies gotten their hands on the 2017 ecu? OF etc...

Fuel pump? Crickets?

No more crickets?


Edit: looks like the post above me, beat me to the punch.

@Celica00 you act like you're new here :bonk:

blimey they did all that work and its only 5 bhp up......

Perhaps they are up 15hp but now actually make the hp they claim! Shame they didn't strengthen the rods
