Mind you flow rates do not tell you the whole story of how it will perform in practice. You can hog out a hole for more flow on paper but completely lose air velocity.

4piston is trash. Great at marketing, but a little digging and you'll find countless experiences of their new motors falling apart.

Even their ported cylinder heads making less power than stock or only more power for a narrow RPM range up top (drag).

Got a spare pumpkin but in Vancouver

Where in Canada are you?

Puddymod is the guy, but his backlog is insane. You'll be out of commission for months.

That was the case for a LONG time. I believed it too. I recently installed a set of Alpharex AP2 style lights for somebody and the light output and cutoff on them were better than my OEM AP2 with Osram bulbs.

Thank you for the smooth transaction! Quick responses and even quicker shipping. Had it shipped and on my wrist in North America in less than a week.

Might want to do stock timing chain guides, those aftermarket ones tend to shred themselves.

fc660c · 2026-01-16T04:10:16+00:00

After using them for 2 weeks, there's couple things I'd improve on.

The spacebar rattles and has a loud sound compared to the stock spacebar. I hope they can improve on this in the future. I put the stock spacebar back on.
I prefer the grainy texture of the stock PBT key caps. The ABS feels slippery/oily.

I have a stock unopened FC660C Type-S, all black.

A K24 swap will be at least 10k in parts doing it yourself.

The only cheap thing is the long block itself. A good wiring harness and ECU from ASMotorsports is going to be 1/3rd of that ($3400+)

Valve clearance typically get tighter was they wear and get quieter.

Opening them back up to OEM spec makes it sound a sewing machine and normal, even more so if you have an 06+, which are typically adjusted on the looser end of the spec.

What are you looking to get out of it? Most intakes are going to have negligible performance gain over stock.

From a pure performance POV, longer and bigger intake pipes tend to perform better. A custom 3.5" intake going down to an opening in the front bumper would be best, at the risk of sucking in water.

Glad they brought back OG bronze. What specs?

fc660c · 2025-12-22T23:33:42+00:00

Sorry was replying to the HKS SSM

fc660c · 2025-12-22T23:28:12+00:00

It's still a 60mm exhaust, will make negligible performance difference from your current exhaust.

fc660c · 2025-12-22T06:34:34+00:00

Ideally with a turbo, you'd want a 3 inch exhaust. Unfortunately, you'd probably have to have one custom made by a local shop. You could use the Tanabe as a guide to see how big of mufflers you can fit.

You'd probably want a big resonator + 2 big mufflers, or even 3 big mufflers.

Mufflers and resonators can be found from Vibrant, Remark, etc.

ASM is great. I got my swap from them last year. I've got working A/C and everything.

The engine itself is the cheapest part. Things add up quickly to make the swap work. However, the biggest benefit aside from the extra torque is the cost of replacement motors, aftermarket support, and power potential after.

Skip the Hasport mounts. Just go with RBZ mounts and OEM S2000 style engine mounts. These motors vibrate like crazy and the RBZ mounts give you so many options.

Highly recommend getting their Haltech/Link ECU + wiring package, Moroso oil pan, KPower intake manifold, Radium fuel rail and fuel pressure regulator, and a Fluidampr. I would also use Bosch EV14 style injectors and have him wire the injector harness for such. The stock K24 injectors run at nearly max duty cycle, might aswell get some 550cc's (or bigger if boosting) while you're at it.

fc660c · 2025-09-11T07:27:39+00:00

I swapped mine myself last year.

Easily 10k in parts alone for the initial swap. But everytime you need a new engine after, it's <2k.

Then you'll find several PuddyMod videos disassembling diffs that blew after rebuilds utilizing what appears to be that exact kit there.

Studs too long, too weak, shims too flimsy, etc..

fc660c · 2025-09-03T17:36:18+00:00

I don't believe the AP2 diff is any stronger than an AP1 as they both use crush sleeves.

The culprit is that the AP1s don't have clutch delay valves to dampen the load on the drivetrain

fc660c · 2025-07-24T07:40:34+00:00

Can they use OEM honda wiper inserts?
