If the main / only differences between the two engines are an increased bore diameter, fully aluminum head, and added oil cooler, is this a workable idea? Hi everybody, So I’m sure this has been a topic of discussion before but I feel like as the engines get more and more miles over time I’d like to hear some of your opinions and discussions on things that you’ve had to maintain and or fix with the new fa20 engines that might be the same or different than the EJs.

So it sounds like the FA24 is detuned in your market and the FA20 is hamstrung by emissions in ours. In the EJ world, the EJ25 block with EJ20 heads was referred to as a hybrid build. I too am more interested in a built FA20 than a kswap. This seems like a fairly doable swap without a crazy amount of effort. That’s why it makes the same power numbers as the FA20 from last gen. Sep 10, 2023 · FA24 is a far more modern engine, with lessons learned from the FA20. The Crew franchise, developed by Ivory Tower(Ubisoft), is an open world exploration and racing game franchise.

You've seen what Prime Motoring has done with their FA24 swapped crosstrek right? Over 500whp on the stock block with the usual bolt-ons and flex fuel? Yes please. 5 that matched the 2. Demonstrates consistent, reproducible oil pressure drops occurring in right-hand corners, especially in sustained corners, or when coupled with elevation change, or rapid lateral direction I’ve been tuning Subarus for the past 3 years. Also, they call the turbo motor in the WRX the FA20DIT here. The latter EJ engines started having issues across the board with ringlands, spun bearings, etc. 6:1 is stupid high for a boosted car).

What's cool too is the fact that's its got the same bolt pattern (at least I'm pretty sure) to bolt up to both STi and WRX transmissions so you could go pretty 'budget' on your build with say a FA24 swapped WRX, heck just put some FA24 rods in your blown up FA20 and you've got a much stronger bottom end. Yet, still a concern and a "weak point". I know everybody only saw the 3hp bump and immediately wrote it off, but the power band is so smooth and there’s no more torque dip. But at the same time, EJ motors have that Rumble that we all love (me included), however having cylinders 2 and 4 be hotter then 1 and 3 seems to be at the same level of annoyance as the FA's Tell you what; you are not alone. ynlhh jttqcb kinz jol rajtp uusi but ove ayot xfmgxf
