So on the old ej20/25 fourms there were obviously different ways people went about doing it. Some people machined the heads, some used different pistons (probably what EMS tuning did), others said “fuck it” and just slapped the heads on the 25 block and probably had to run super conservative tunes. One thing I thought was an interesting idea was using a thicker head gasket. Grimmspeed currently sells a 1.45mm thick head gasket, which is over twice the thickness of the oem head gasket. My question is if someone were to reach out to grimmspeed about making a fa24 head gasket in that thickness, would it be enough to make the fa20/24 build viable without machining the combustion chamber? Depending how the head work goes by op this way or way not be worth looking into further. |

Something to consider is that just because the part number is different doesn’t mean the part is actually different and won’t fit. Changes in part numbers can be caused by small revision changes, change in manufacture, material. PN coding has a lot to do with QC. Honda does this to me all the time.

The FA24 timing cover looks like a winner, Subaru probably made some other improvements inside. |

Nah, just snapped a pic of a 2nd gen at the shop that was in for an oil change. The oil pickup tube looks improved as well, made from some kind of composite material. Grabbed this pic from a Japanese website...aftermarket baffle plate. |

Wow that is a completely different design. Strange how it has that small opening and then it gets bigger (maybe there is a filter in there) and then seems to neck back in. |

I don't like it. It's probably just fine but there's a reason breakaway tabs are skinniest where they're supposed to break.

Reminds me of the k series Frankenstein builds but damn that’s cool. If the new short block can solve the fa20 oil issues on track this would be a serious contender. One down side is it’s got to be pretty expensive with a boxer, two of everything with head work.
