So it’s basically the same price as the FA20 short block. I got FA20 short block through a friend at a dealer for around 1800. I suspect the FA24 could be had for similar discounts if you know the right person.

Curious about @Opie plan for the heads to get compression back to 12.5 The FA20 heads will actually introduce a quench/squish area when paired with bigger bore of FA24 (which I guess can be desirable for velocity and mixturing). Probably also need a head CC kit to get compressed volume even across all 4 heads if material is taken out.

Surprisingly so. Probably looking at three grand once you account for the ancillaries. Then what else do you need?

-Header, if you're still stock?
-Tune? Which might become available off-the-shelf in the not-too-distant future

If that works out, it might yield 250 OEM-like hp for the price of a decent supercharger. N/A, with a "new" engine, higher reliability and less weight.

Speaking of which, interested in seeing the weight penalty between FA24 & FA20 short blocks. Probably less than an FI kit anyway.

I doubt it’s much more. I guess the steel sleeves are larger but could that really add up that much?

Decisions, decisions….
@Opie Are you considering the upgraded transmission, too?
Not until/unless the current one breaks

I'm gonna assume the weight penalty is approximately one large dump after taco night.

Is it not the FA24 short-block longer? Hope you don't have clearance issues.

No. It should be the exact same size externally.

The question here is will it use the same CPS (crank position sensor). That's another critical sensor you'll need to determine engine position. If it is different, it may be possible to swap the gen 1 sensor in.

Shouldn't the FA20 headers fit then?
