I weighed the engine today: 375 lbs ready to run including starter, flywheel and filled with oil. The transmission weighs 175 lbs with axles and oil.

Little bit heavier than I thought. but not by much. I do know axles are heavy. Still a good engine choice.

Yeah, it's heavier than I expected too. I think Kurt stated the K24 engine and transmission at just over 400 lbs. This SRT4 weight does include turbo, alternator, oil cooler, engine and transmission oil and axles, which I don't think were included in Kurt's measurement (correct me if I am wrong!) I tried to be as "all inclusive" as possible. There is probably some weight savings to be had in an aftermarket turbo and manifold, and aftermarket flywheel. Those bits are heavy!

Correct on all counts. The K24 was complete (though may not have included axles), and your correct about not including the turbo. That along is probably 30-50 lb. for the turbo, wastegate(s), extra piping, and intercooler.

I don't think that you weighed the k24 with the axles. From all the searching online, most 4 cylinders all weigh in the same ballpark. Kindof funny if you ask me.

From my late-2008 build diary:

So what does a Honda K24A1 weigh? Engine + exhaust manifold + alternator + starter = 283 lbs. This does not include the flywheel or clutch (I have neither), nor engine mounts. The 5-speed transmission weighs 87 lbs + 10 lbs for the intermediate shaft, for a total of 381 lbs. Figure 8 lbs for an aluminum flywheel and maybe 15 lbs for the clutch. As far as I can remember, these are the same parts included when the H22A1 was weighed. So the grand total is 403 lb. though neither total includes the engine mounts and axles...


I've found the same, that regardless where the engine's from, they're all about the same, which makes sense. Once drivetrain I never did got an accurate weight on is the VW VR6, still kind of curious about that one.

I made a resistance/temp table for the stock SRT4 Intake temp sensor:

*F|K ohm
-2|86.0
30|31.0
40|22.66
66|13.40
88|10.00
125|3.00
147|2.245
188|1.185
198|0.935
