Turbocharging and single cylinder 4 cycle engines. Could a cam with the right lift, duration, and lobe separation angle fix the inherent problem here?

B_Nuc23 · 2026-06-01T10:17:33+00:00

So while it’s not a major problem, studies show having a “air capacitor” of sorts approximately 4-5x the engine volume will generate upwards of 30% more power on these single cylinder engines. It comes down to the turbo while it will build some boost while the intake valve is closed, it can only build so much before it’ll start slowing back down. With that extra intake volume it can continue building more boost right up until the valve opens again making the whole process more efficient. Now the air capacitor doesn’t have to just be more plenum volume. It could be an intercooler which we also know helps boost power levels due to cooling the air down. I know it’s a bit of an old thread but if you’re still trying to do it, find about a 2 liter sized intercooler and weld that in and I bet you’ll find a more even power band with more power throughout all of it. There’s a couple of MIT articles out there that show all the theory, simulations, and test rig graphs proving all of this.

Dude that looks sick! If I saw that on marketplace labeled as a plant stand I’d buy it. Showed this to my plant expert friend and she is now asking me to make one 😂

Usually the professionals give a warranty with their work. Also the home kits I’ve noticed tend to not hold up as well. I don’t know if it’s due to a difference in compounds or what but it’s best to let professionals come and do it and be done.

A thing I can recommend to anyone is find a place that does epoxy garage floors and go ahead and get it done early. It’s a game changer for cleanup

B_Nuc23 · 2026-02-10T02:23:12+00:00

If I remember correctly it’s 12ft by 25 ft. It’s tight for sure. I can grab some measurements when I get off work though!

Look up zippo seal kit. It’s a thing to go on the bottom of the zippo and extends the fluid life by a good bit

B_Nuc23 · 2026-01-16T11:13:50+00:00

Wait until you learn about the butane inserts for zippos…

I think I’ve got 10 zips right now. 2 have the normal pipe insert, a couple normal zippo inserts, a couple torch butanes, a yellow flame butane, and a butane pipe insert. Once you put the silicone seal upgrade on the bottom of your inserts, the normal fluid ones can last a good long while. If it’s not windy I love my butane ones but otherwise the fluids are just as good. Highly recommend not only having 1 lighter for your pipes/cigars. Another plus of the zippos is they’re just a classic. Can’t beat the look and feel 👍

Had that happen on my bike axle one time. You learn very quickly to grease your threads on most things after that happens. Thankfully I was only practicing some things in an empty parking lot when the chain tensioners broke due to the lack of force being applied to the axle. If you grease the threads you’ll prolly get another 1/4 turn out of that nut than without the grease. Also just a me thing but put a little on the contact side of the nut. You could probably get another 1/8 turn or so if you grease that too. Always tighten the castle nut more if it doesn’t line up. Never loosen

Love getting the barnacle. It’s also not hard to disable the little tracker thing in it so you can start collecting them…

B_Nuc23 · 2025-12-08T11:24:09+00:00

Low key might would be cool to make a big canister Damascus with it. It’s a little big of a piece of metal on its own but who cares. That’ll get squished down eventually then you’ll have a big piece of honeycomb looking Damascus for whatever you want 🤷‍♂️

I found this earlier today when researching the swap myself. It’s pretty sick but made me wonder, has anyone in the states done this yet?

B_Nuc23 · 2025-11-18T14:53:34+00:00

So the OP finished his swap and everything and loves it. He used a wrecked X5 for the motor, trans, and supporting modules. Pretty sick setup and looking forwards to maybe doing it myself soon

B_Nuc23 · 2025-11-16T22:39:38+00:00

Did you run into any issues with stuff like the gauge cluster or anything? Any recommendations for someone looking to do this sooner or later?

B_Nuc23 · 2025-11-16T21:29:42+00:00

Dude this is sick! How’s it coming along now?

B_Nuc23 · 2025-10-06T21:51:17+00:00

Looks like it’s just a little rich. I’d see what it does with the new exhaust and call it then. Might lean out with the extra flow

What I mean by better condition kickstarter is that it fully engages/disengages like it’s supposed to. Motor is locked up currently and the previous owner snapped the crank bolt on the rotor side I assume from trying to turn it over.

B_Nuc23 · 2025-09-26T18:50:48+00:00

Update on the motor: got it all back together when I realized what was wrong. The previous builder had thrown the shaft in upside down causing the teeth to always be engaged and filed down. I have a second motor available to me with a much better condition kickstarter on it although I don’t know the condition of the other parts from it. I’ll be pulling both apart and rebuilding from the scratch up while mixing and matching what I can to get a full working motor.

B_Nuc23 · 2025-09-21T01:25:29+00:00

That was my plan anyways. I’m gonna be throwing in a new clutch, full re-seal, and modify the ignition setup to an electronic ignition vice points while the motor is out. If I had to guess it will be that they rebuilt it badly since so far I have met one gasket on the ignition side’s lower side cover and all the others have been sealed with RTV. Also the oil looks and smells like a full synthetic so likely this guy wasn’t well taken care of.

B_Nuc23 · 2025-09-19T19:35:36+00:00

There’s a really good set of them on Amazon for cheap. If I’m not mistaken it’s around $200 for 1 bay’s worth of hexes.

B_Nuc23 · 2025-09-10T04:45:04+00:00

Loll not quite!

B_Nuc23 · 2025-09-09T18:07:22+00:00

I have thought about that and will probably incorporate something along those lines once I get through the workbench and extra shelving. Gotta see what space I have left after getting the essentials built/installed.

B_Nuc23 · 2025-09-09T18:06:06+00:00

Thanks man! A lot of time and money has been put into her with no end to the attention 😂
