http://www.larryspower.com/heads/Chambering.html The guys in thailand claim to have done it with the stock ECU in their 17'. Who knows what they did though, probably just stuck the 17' sensors in the FA24 block is all. They are using the FA20 heads but not sure which timing cover. I know one reason we can't run the FA20DIT timing cover and get that sweet, sweet larger oil pump, is that the cam sensor port isn't in the right spot. Not sure on timing cover compatibility FA24 vs. FA20 though.

I am pretty much in the same position. I have 100K+ miles on my engine, 40ish track days with more to come. It's only a matter of time. When I go to refresh curious what options will be when that time comes.

I only have 60km on mine but around 35 track days. It is only a matter of time. I'd prefer to have an engine ready to drop in but haven't had any luck finding low mileage used ones. I so wish they dropped this engine in a half dozen other models

For the cost and hassles, better go with FA20 forged. Plug everything back like before

If I wanted boost, I would agree with that. Staying NA I don't think the forged bottom end is worth it. It doesn't really gain me anything power wise, and at twice the cost of a stock shortblock, it would need to be twice as reliable to pencil out. I'm willing to deal with a bit of hassle if more power is also an option Bench wrenching is fun though. Hopefully we see more development on this in the future.

Original crank is forged anyway, and the weak point (if any) is the rods (leaving aside the known oiling issues). Cast pistons are more thermally stable than forged as well and allow for tighter clearances in the bore. Aftermarket pistons tend to be forged to be more detonation-resistant, which is great for FI applications but much less important in an NA application presuming the tune is reasonable.

My guess is this shop is using the FA24 block with WRX FA20DIT Pistons, FA24 upper & lower oil pan assemblies & a FA24 front timing cover with farely standard FA20 heads....

Swapping piston's would be a bummer.
