Important Correction: we welded the Bimmerworld front subframe reinforcement plates on the topside, but we should have welded them to the bottom side (which would explain why the shape of the plate didn't really line up perfectly with the topside.

[@speedacademy]

It's reinforced in the right area, so I think we're ok to leave it as is, although it does raise the engine a bit with the plates on the topside instead of the bottom. Not ideal, but not the end of the world either. We'll keep an eye on it for any cracks forming.

[@canadianexposures]

So you replace the clutch and flywheel... Finish the build... Drift it... Sell it to Throttle House... and the clutch fails on them shortly there after. LOL, good thing you went upgraded.

[@gianniarduini3644]

You have to weld the whole plate if you don’t humidity Han get where there no welds which can cause corrosion in between the subframe and plates

i really appreciate the consistency of these build videos. i did some build videos (about 30 or so) like 3 years back and it was so time consuming setting up shots, researching (so you dont look like an idiot), filming, and editing. i eventually gave it up because the car burned down but your channel has kept my itch scratched for awhile now. i got a thumbs up the other day when i was wearing my speed academy shirt too!

[@FATmenDRIVEtrucks]

Yes it's bad lol

[@TheMojomoto]

great series guys, just FYI regarding the guibo: check if it has thicker and thinner parts, because if that is the case, you have to mount it in a specific way: the torque needs to transfer through the thicker part of the rubber, not the thinner part. So make sure you put the bolts in the correct holes. There might be arrows on it to help orientation, but not always. blog.bavauto.com/14113/bmw-how-to-properly-install-driveshaft-flex-disc-giubo/

[@Drgoldthumb]

Love this e46 rebuild series!!! ... all though now I’m realizing how much more maintenance I still have to do. :-)

[@BurzzyJ]

Great videos guys! Keep it coming. I'm excited to see it all finished! I would love to see a cost breakdown of the build once it is complete.

[@FranRuiz]

My OCD is killing me! please clean the rust of the subframe and put some nice paint on it! hahaha Cheers from Argentina guys!

Love it when you guys restore as much as you can!! Great video!! Bring moose back also lol

[@franciscovasquez4555]

Great tips and insight for low cost replacement parts

[@Jeffball610]

I hope you guys love the gel loc-tite as much as I do. I still prefer the "glue stick" version more, but anything beats the pure liquid tubes that make a mess and seems to run out quickly.

[@deweberis2709]

It looked like Pete was trying to couple two space stations: gearbox and engine 😂 Next time when you wanna reinforce two rubber materials/textures, try to put it in an over to merge it by vulcanization.

[@Anthraxegott]

I hope you guys don´t forget to remove the CDV from the slave cylinder.

[@Ovadose850]

Anthraxegott yeah removing the clutch delay valve would make it a much better drift vehicle !

[@tysimon]

Not to suck up, but that clutch looks fantastic!!

[@orangexxxx3140]

That part is called a guibo, the center of the drive shaft is the center support bearing. You should change this as well I am sure it's gone too. Also do the CDV delete it's a cheap part but makes a difference.

[@sr20vett]

Hey DP and PT! love watching your stuff! I couldnt help but notive you forgot to torque the oil pan bolt sin correct sequence. It will leak unless you loosen them and retorque in sequence. I know cuz I made the mistake once lol

[@kalebthompson1]

Is this an e46 specific problem? Ive never done a specific sequence on any e70s, e9xs, f30s, etc. and never had an issue with leaking. I just do the 8nm + 90 and 180 depress.

[@zerotohero7449]

With the guibo it is imperative that the bolts go in the direction of the little arrows embossed on the side. Otherwise the guibo wont last very long.

[@speedacademy]

Good tip! We'll double check ours.

[@jman566]

Anchor motor mounts generally suck. They last about a year if you’re lucky. Can’t wait for the drifting though!

[@georgepoling685]

I have an e36 but it’s virtually the same. I would change the steering shaft bush to a solid one, and also do the rear subframe enforcements!

[@IWK333]

Yup, the rubber part you changed is popularly called guibo... In reality, it's just another type of universal joint/u-join, it's primary job is to allow for a certain change of angle in the driveshaft, it's only secondary job to dampen the NVH/cluth engagement as a bonus 🙂 The things in the middle are (at least in e36 and e39, I believe e46 is same) a classic u-joint and a center bearing 🙂 Not hating, just trying to be informative 😁 Also, as a few people have mentioned, rear subframe mounts (on the chassis) are a serious weak point, you should definitely consider reinforcing it before drifting the car 🙂 PS I now started thinking that my e36 might have clutch pivot issues, as the clutch is acting funny 🤔 Thanks, I completely forgot about the possible issue with it and was considering replacing the whole clutch set (expensive) or replacing hydraulic components (labour intensive) 😊

[@fahisaurus]

Bimmerworld makes solid rubber engine mounts but they are pricey ($200 USD for the pair I recall). Also consider doing wheel studs.

[@earnestbunbury2103]

[@fahisaurus]

@@earnestbunbury2103 they're like $600. That's an absurd amount for motor mounts.

[@R0adsterr0land]

Swap those stock exhaust manifolds with some headers. There's powah in there!

[@EpicBurnReturn]

You hippies crack me up!! Keep up the good work

[@y2ksierra]

All E46 mounts should be the same. I put lemforder ones in mine. Good quality and didn't break the bank. I believe they are the OE supplier on a lot of rubber parts but not 100% sure if the mounts are one of them.

[@waseatong2263]

Thank you so much for sharing such a wonderful video~

[@jeffreymoore4132]

One of the issues I've found with those replaceable friction rings is how true they are. I could of just had a bad experience, but should you ever have to replace it, definitely check its installed run-out. "reinforced rack" I see what you did there ;-)

[@PirataSports]

A great episode.

[@JDM_Jeffro]

Great video guys!! 🔥🔥🔥

[@ghettoflyer]

Food for thought... Did you know in drag racing they use heavier clutches? Just like fly wheels on old farm tractors, heavy flywheels store energy the more energy on tap/ available at any given moment means it will be easier to break the tires loose. In drag racing the big heavy flywheel makes it easier to do a burn out when one dumps the clutch so the motor doesn't stall...What is a drifting, but a big burnout while cornering...? Everyone is obsessed with lighter fly wheels and I don't always think it's the right choice. (trying to get people to think about their purchases)

[@goldenhide]

Very true, I think the converse is more track and touring races as the lighter wheel "revs down" slower as it bleeds energy on a downshift, which obviously has it's own pros/cons. Again, something you want in certain applications, but not others.

[@gerardwalsh4724]

If only this was a coupe, this series would blow up! But still super helpful. Keen to seen what you guys do in the boot :)

[@turbomopie]

Good work fellas

[@elijahherman]

Awesome content thanks guys

[@corwininadsm]

BTW these motors make good power with headers. Even the Euro headers make decent power over the North America ones.

[@riyuiwashere]

Nice build.

[@Carlosiemon]

You guys are doing a great Job replacing parts that can potencially fail. One coment about it. You should have spent a few dollars more on those engine mounts. They dont follow the logical things that you did with other parts that were replaced and are better than the OEM

[@ledmk2]

Nice video

[@Courtathor]

Why didn't you go for the popular purple tag rack upgrade? Wouldn't a quicker ratio rack be beneficial?

[@jsinghmoments]

You guys should change out the stock headers as well!

[@speedacademy]

tempting to do the Euro headers, for sure.

[@jsinghmoments]

@@speedacademy Do it! I highly recommend it! I changed from stock headers to CPI stepped ones on my Z4M and even without a tune it feels better. While getting the headers installed, the indy told me that on their spec m3 racecars, they added intercoolers, oil coolers, etc, to keep the car cool on track, but kept getting high engine temps. Since headers had a high point penalty, they didn't want to do that, however when they switched to the euro headers (and removed the other stuff to keep within class specifications) engine wouldn't overheat as easily. I thought that was pretty surprising, it's one data point, but if you're going to drift the m3 may as well do it now, while everythings easy to reach :)

[@LFCsince93]

I did the anchor brand engine mount thing about 10 years ago. Be prepared for them to wear out after 8k

[@tomingebrigtsen8976]

Probably even sooner since they are building it to drift... high rpms and clutch kicking will probably tear them in no time.

[@LFCsince93]

Tom Ingebrigtsen is I remember correctly they were less than $20 a piece back then and for me was cheap to buy but labour added up doing it multiple times at a shop. These guys will be swapping those out in a couple months. Good channel and I like their builds. I too am from Ontario. Nice to watch

[@sebericpas]

Corrected me if I'm wrong but you have installed your clutch disc on the wrong side!!8m44!!

[@gregmtech]

most S54B32 performance clutch dics with absorbtion springs like the one in this video ; are ment to be fitted with the spings towards the flyweels ( designed to accept the spring carrier without interference ) if put the other way the spring plate woud be contacted by the pressure plate fingers. this setup can only be put together this way and designed to be like that ; the Sachs ZF pressure plate / clutch combo is the same and can only be fitted to a lightweight flywheel as the oem dual mass is flat and does not accepte the inverted clutch disc. . but you are not incorrect to mention this as yes a clutch disc is usually ment to have the spring plate outside.

[@tobetinkering]

That valve you are talking about (2:16) could be the oil pressure bypass valve that is used to bypass oil filter when oil is cold (kzbin.info/www/bejne/jqbUhqmXrJiqnrc) but its only a guess from my side

I'm not against using plastic on a car, but a plastic throwout bearing? Seems like a strange engineering choice to me. Also, would it be fair to say that if the average person bought this car, it'd probably be a bit of a money pit? That is, if you just wanted to make it stock from the way you bought it, the average home mechanic/tinkerer would probably have given up at the cost of things? Not knocking the choice to buy it, but maybe something to point out to viewers thinking about buying old M3s - it's going to save you money to buy a nicer street car than to fix one like this.
