It sounds amazing

[@IvanOoze1990]

all you can hear is the supercharger.

[@ilovehappyemos]

The later M90 superchargers off the 04-07 GTP came with a drive-by-wire throttle body. Not sure the throttle flange would match that Gen 3 blower, but the 04-07 blower (gen 5 m90) are more efficient. Also, there is a tool out there to machine the snout down to run a smaller pulley, and all you need is a drill. As someone who has messed with a lot of GTPs, that blower sounds like its spinning about the stock speed for a 3800, so you can definitely go down a couple sizes on the pulley. The 3.6 is going to be way more efficient at moving air through than the 3800 could ever dream of being lol. Awesome build! Thanks for the inspiration.

[@BlackthumbTV]

Thanks for the info! I had also considered driving the blower off a custom pulley on the alternator to fix the issue, but I'm trying to contain myself as I don't think this engine can handle much more (given what I've seen from the turbo guys). The drill-tool sounds quite interesting though, I'll have to keep that in mind just in case.

[@twizz420]

@@BlackthumbTV I was in the 3800 groups for a long while many years ago and that guy's not lying. The pulley was one of the main upgrades for the m90 supercharger. They can make way more power with just a pulley.

Awesome video, I think this may be the very 1st supercharged Subaru engine that I've seen.

[@TexasGTO]

Port the blower. You'll gain about 1-2 pounds of boost. You can do it at home. Would be a cool video. Thanks!

[@RandySpycyWeinr]

As a Subaru guy and love your content. This is the kind of car shenanigans. My 1st swap was a JDM EJ207 in to a US Sti. Doesnt sound special but back in 2009 it was rare because of the US spec STi was a completely different ECU, sensors and wiring. I had to solve all these things myself, no guides, no kits. Nothing against the bolt-on guys, I just need more of a challenge. Im blessed with the ability and knowledge to completely assemble, install, manufacture small things, wire and tune. This channel is gold to me. Thank you Blackthumb.

[@titaniumoverdrive259]

I’d love to learn that shit For the sake of the hobby

[@adeadlyfart13]

Looks like that engine could benefit from some motor mounts, other than that this an awesome build. I appreciate the enthusiasm!

[@rushthezeppelin]

Exactly what I was going to say. Maybe some poly or even aluminum mounts would be wise with how much that engine is bucking around now.

[@tbas8741]

Looks like the Bell housing Pitch Stop Mount Bushes are gone also the factory Pitch Stop arm is pretty compliant. It ties the block directly to firewall to prevent engine rocking back.

[@brodyfinlayson1321]

This is epic. mad love for the ez30. some solid engine and transmission mounts would definitely increase the driving experience. After installing Kien mounts in my 04 6 spd ez30 legacy, the throttle response was so much crisper and the engine noise inside the car increased massively. highly recommended for maximum auditory enjoyment.

[@taylorhickman84]

yeah that motor movement looked a bit extreme. how does the 3.6 compare in terms of reliability to the 4cyl?

[@brodyfinlayson1321]

@taylorhickman84 3.0 ez30 is a lot more reliable at similar power levels (240hp) than the ej. But not so much when boosted. The 3.6 is weaker than the 3.0

I'm so glad I stumbled across this video. I absolutely love oddball, homemade, DIY builds like this. I bet that thing is a lot of fun.

[@fun6243]

I like it. You need to max out the stiffness on your mounts and soften up your suspension. You working with a split block so you need to watch an sti buck under boost. Try and hit that mark. It's something you can fabricate for a cheep awesome and effective solution. Have a blast.

[@kendrickwilliams3696]

There is alot of space to fill with boost. It would have taken longer but separating the big pancake manifold into individual runners would have helped power and response drastically.

[@BlackthumbTV]

It doesn't make as big of a difference as you'd think. I tuned a Miata with an intercooled supercharger kit, where the intercooler was after the supercharger/throttle body, meaning it would see both boost and vacuum. It did make a difference in both time to build boost and time to build vacuum, but nowhere near as much as I had anticipated. This setup builds boost as fast as you can open the throttle effectively, and change to Decel/vacuum delay isn't noticeable vs the stock manifold.

[@xbox230]

You’re content is so entertaining dude, you do such a good job showing your process. I’ve been wanting a classic jdm car that I can mess around w and learn how to do all this stuff. I wanna do all of this you’re doing but I’m on such a small budget and very little knowledge so you help a lot

[@Tiberiumfreek]

The fun part about just slapping it together with improvisation, is the chance to make it even better! Slowly work better and more proper parts into the project and really fine tune the performance. This is really cool! I love to see how people can just find a junkyard super charger and slap it onto an engine, never designed or intended for one.

[@CrackerSmith]

Adding extra dampening to the engine using stabilizing struts should help minimize the lurch during shifting. I think this will help it be even faster.

Just found you in my recommandations and i love it!😅 That is what car tuning culture is all about and not another guy who rebuilds a supercar (nothing wrong with that but to much here allready).

Yep, she rips now! Would be fun to see it at 14psi four that double-ish HP feeling, but I gotta keep myself under control.

[@BlackthumbTV]

LS swapping is possible, but with the subaru trans it'd hang way out the front of the grille. I remember seeing one a bit ago, it didn't even have much of a front end left. Just engine

[@rickcupola6262]

The Ferrari V8 Subaru rally car is an example. The engine sticks out of the front axle like an Audi, to a lesser extent. A front mounted heat exchanger in this setup will be tricky, because the engine will be colliding with it, which is physically illegal.

I'll have to check out some more of your content. One quick question, what kind of tuning did you have to do to get it to run with that boost, if any?

[@BlackthumbTV]

Any vehicle will need a tune when you modify it, especially when adding forced induction. Check out my video on ECU tuning for more info on why. All my setups run standalone ECUs for what it's worth, I don't typically run factory engine management.

I had a 98’ 2.5RS from 98 to 2003ish. I used to roll with another 2.5RS guy every now and then that had positive displacement supercharger on his. It was pretty fun.

When i wanted more, and had already pulley swapped, and since im not "crafty", i opted for a 100 shot (dry) of nitrous oxide activated at w.o.t. as we know, superchargers make heat, heat removes horsepowers, nitrous is a bit chilly, the cooler air charge makes all those extra horsepowers and torques

[@BlackthumbTV]

I'm all to familiar with grenading engines, check out the video about the K swapped Subaru

[@FluffyMI6]

If i may: the design is very practical and definitely works for your project. However, if you wanted to improve the design of your super charger intake, you could make it more arrow like to help improve the ease of air flow. As it stands, the intake works and very well at that. The air thats being pushed through it, though, has a LOT of right angles to go around in order to get into the engine. It may not provide much more boost than what you have here, though it would definitely be easier on the super charger in the long run. Love to see DIY car projects though! Great job!

Theoretically, if you know what DPI the images were scanned at, you know that X number of pixels is one inch. This information usually gets embedded into the images automatically, meaning you shouldn't need to scan the ruler. I was under the impression that most CAD software would scale the image automarically, but I'm not sure if that's true or not.

[@BlackthumbTV]

Unfortunately my scanner creates PDFs so I was unable to find the DPI metadata in it. I'd rather scale like this for reliability anyhow

[@BlackthumbTV]

It was a thought, but Richard Holdener did a video on a 3800 with this supercharger AND a ZZP intercooler kit. The long short of it is that, while the temps dropped substantially, the HP gains were minimal. So I deemed it to not be worth all the additional fab work.

[@Thereis1]

For all the turbo fanboys out there: you're right. Turbos are more efficient and generally better for mid and high range power. BUT! A proper roots or twin screw blower setup will provide electric-car-like low end torque and works instantly. They love being short shifted and just "feel" the strongest. Also the sound oh lord the WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE is intoxicating. More so than aggressive turbo spin and blow off valves. I've had NA, single turbo, twin turbo, centrifugal, and roots type cars and the roots/screw blowers are the most fun to drive; the second being the twin turbskis. Thanks for coming to my ted talk

[@BlackthumbTV]

I had actually planned to say something like "this build reminds me of driving a Tesla" but I know how the car community feels about EVs didn't feel like being burned at the stake. And too many people are just focused on getting the biggest horsepower number. Which is also fun, but this is fun too. Turns out, you're actually allowed to like multiple things 🤷

This popped up in my feed today, so glad it did! Awesome build man!

[@pr3modeling239]

One other thing you could do to increase, not necessarily boost, but how fast it comes on, would be to reduce the volume of that intake plenum. That's a lot of air volume for that little supercharger to compress. If you could reduce the plenum volume by 50% I bet you'd see a large benefit in boost response.

[@BlackthumbTV]

Out of curiosity I just checked a datalog, and I go from vacuum to full boost as fast as I can push the pedal down between shifts (less than a second). It actually comes on so fast that I grenaded second gear, so I gotta be careful with it!
