This video saved my marriage.

[@BlackthumbTV]

The Blackthumb method really works!

[@ApostateAladdin]

I enjoy every video of yours despite never tinkering with cars. Love your sense of humor and your willingness to help people. I hope your channel continues to thrive!

[@BlackthumbTV]

Glad you like them!

[@wardvandroogenbroeck786]

man i hope well get a new vid soon i miss this dude

[@802Garage]

Thanks to this video, my wife's boyfriend finally gave me a thumbs up when he left in the morning.

[@NLRevZ]

I can personally work around the Letter vs A4 difference, but for the global audience you might want to make a 'native' A4 paper version of the output :)

[@BlackthumbTV]

Didn't even think about this. Consider it done!

[@gunnerblood3253]

I don’t have the words it takes to express how much my lil nerdy car brain loves this channel. Great job my man!! :)

[@MegaButze]

thank you for adding metric units as well

[@BlackthumbTV]

The best units tbh

[@holidayfestivities106]

I successfully enlarged my tube, thanks BT! Unfortunately I spent so much time in the shop enlarging it that my girlfriend left me, so she is no longer around to benefit from the fruits of my labor. I'm going to go replace a blown head gasket to help soothe my heartbreak.

[@BlackthumbTV]

Glad I could help, and don't worry! There are many others out there who can benefit from now-enlarged tube!

[@Hakiri27]

ran into you at the curve today, had no idea you were anywhere near me, absolutely love the legacy. I'll grab a head gasket meme shirt when I get a job :P

[@TEAMPHY6]

Self deprecating humor is best humor. Subbed

[@curdisdunn5414]

Never thought another dude and a store bought Doug would actually enlarge my tube but it did ty lol

[@brokeafengineerwannabe2071]

Doug is truly one of the welders of all time

[@BlackthumbTV]

[@ultraali453]

Blackthumb Made Tube Reducer Tools and Me: This Sort of thing IS my bag, baby! by Austin Powers

[@BlackthumbTV]

I seem to remember Austin Powers having a tube enlarger too 👀

[@darthmikey9180]

So what's the new project. Are you rebuilding the k swap subaru?

[@BlackthumbTV]

I'm actually K swapping an RX8, and slapping a variable geometry turbo from a Cummins on it. Using the parts from the K swapped Impreza as I don't plan to do another Honda in that chassis. Still planning to put something weird into it, though, just not right away

[@darthmikey9180]

Amzeballs! I saw you teasing the variable geometry turbo a while back. I can't wait to see that bad larry

[@davidengel3309]

What upgrades, which won’t cost me a kidney 😂, could you recommend me for a 2004 Subaru Legacy Spec.b 3.0R with an EZ30 engine? It currently makes roughly 250hp, bone-stock bar the exhaust (stainless steel with a central muffler delete).

[@BlackthumbTV]

From what I understand, headers and tune really make the difference on this engine. The Skid Factory channel has an excellent video that goes over what you can do for these.

[@BuilderBreakerRemaker]

Nice work, I like the tool

[@wwcrxww]

😂😂 FIRST LINE YOU SAID = LIKED!!

[@makeitup3093]

So shouldn't need the grinder or printer thanks

[@UnauthorizedServiceTech]

All you have to do is go to any exhaust shop and demand it right now and for free. 😂

[@RandomlnternetGuy]

Where'd you go? I miss you so. Seems like it's been forever That you've been gone.

[@BlackthumbTV]

Now I Never knew that I was hurting, but in fact Every time I took a her in it was the burner in the back But if that burner was the cause of all the pain (song about my K swapped RX8 rn)

[@RandomlnternetGuy]

@@BlackthumbTV you're a legend hahaha

[@3ToeCo]

Tubular!

[@WhatWhiteMenSay]

Bring back the supercharged legacy!!!!

[@BlackthumbTV]

I drive it all the time. What would you like to see done with it?

[@WhatWhiteMenSay]

@BlackthumbTV well I remember you saying the 5 speed was weak. Maybe a 6 speed swap? Or more power out of it?? New stronger clutch for dyno run. Shoot. New exhaust? All of the above haha

[@WhatWhiteMenSay]

@@BlackthumbTV or supercharge a wrx like a 2002 one or whatever you can get your hands on. I love the top mount super. Most people who do supercharge use a procharger

[@BlackthumbTV]

The car is honestly built to a good power level. The engine can't take any more, the trans can't take any more, the supercharger is running pretty hard already. The exhaust flows quite well. The fuel system is basically maxed out. Any other mods to make more power would basically require everything else to be upgraded and I don't quite have the means to do that right now haha. Especially considering I'm just finishing up a pretty crazy RX8 K Series Turbo swap, that I'll be posting more about here when I get more time in the car. I do plan to take the supercharged Legacy to the drag strip here soon though, just waiting for the weather to break!

[@WhatWhiteMenSay]

@BlackthumbTV I can't wait to see. Yeah maybe the 6speed swap would be the best thing for it then haha. That way it can handle more power and not grenade the trans

[@BlackthumbTV]

Fred got destroyed in poker last I saw 🤔
