I love the idea of making cars that GM didnt, an L67 Firebird is a dream project of mine. I love this. Have you ever seen those optional "Salad Shooter" wheels? those unique oem things feel right for an supercharged 'bird

Thank you!!! I just spent the whole weekend freaking out about this but one pass with the old cam and it glides like butter now.

Would it be much harder to super charge the stock motor

I am only 12 minutes into the video, ive been wanting to do a L67 swap into a rwd car. The thing that i had questions with, on the L67 the starter is on the drivers side once you 90° turn it, how did you get away with this? I jnow the blocks are the same so could i tap and mount the starter onto the passenger side?

Where is this located

Great video buddy thanks!!!

Vent issues I just drilled a small hole in the gas cap #Solved

I wonder if you could keep the throttle body flange in the back, copy it out of steel then build an adapter manifold out of steel?

This is very informative,I’m going to haft to try this because I’m on my second set of bearings on a lc9..I done several other blocks with success but this particular one is being stubborn..

Great info, I have a question if you don't mind, If i was going to use a naturally asperated manifold and heads in a turbo application do i get around many of the issues you delt with using a super charger?

And also could the fwd super charger be swapped to fbody engine instead of doing a whole engine swap and just use the parts?

Hey so might not get a comment back but is that a v6 out a fwd he’s putting in a fbody?

I loved the part where you said we g body guys dont have alit of $$$ signs ...felt it to the core

That was a great in-depth video. Learned a lot from this, thanks!

Thanks for the updated content by any chance do you have any video explaining the upper control arm bracket on that ZR2 axle I'm interested as I'm doing somewhat similar

sub# 1000! 😄😃

I have. Series 2 in the planning process I really want to put this engine in a new edge mustang or fox body but I am trying to figure what platform will Work best ?

I read all about this online today. You're a hell of an engineer sir.

Do the cam man

"Because weird projects" The best projects are the weird ones.

What an fittings are on the fuel pump unit

Besides the fast ratio steering box from Firebird which are difficult and expensive to find, a steering box from a mid 90’s Jeep Grand Cherokee will also work. Also, replace the rag joint on the steering shaft with a knuckle joint.

I did the same things on my ls3. Just make sure you do only 1 cut on each cam journal and they should all be the same direction.

This has been a common machine shop practice for years . Nothing new for a correct fit .

Ingenious!

What if you have the factory 2002 ac compressor

Did you have to put a check valve /one way valve on one of the pumps?

👊🏾💪🏾💯

Do you still have the supercharger ?

If there a parts list to show how to mount one to an ls2

What made you decide to buy a bunch of rebuild parts instead of buying a built one from a company?

It’s a 2.8 l v6 s-10 bell housing bolt pattern?

Whats the approximate power limit of the M122 supercharger? Could it get a Gen III LS to 800HP-1000HP. Provided that the camshaft, exhaust, intake, and tuning is correct? I realize that it would be hard for a 4.8LS to reach 1000HP or even 800HP (if even possible). As much as I like immediate response of Roots style superchargers the boost can't simply be turned up like with turbochargers. Thanks for any thoughts.

Hey, do you have a wiring diagram for the cooling fans to 3 relays?

I thought my m90 swap was a pain in the ass, yours was worse. I bought an adapter plate to mount the m90 to a Holley lo ram manifold. I cut my m90 with a sawsall and it took more than an hour. I ported the m90 and had 1 90 degree 4 inch tube tig welded to it and had to have another 45 degree 4 inch tube welded with v band clamps so I could attach the throttle body. I had the silencer ports welded shut by the same guy that welded the 4 inch tube on the blower. I had to buy a custom 2.55 inch supercharger pulley from Nathan Herbst of smoothflow pulleys which had the ribs going to the edge because of a belt misalignment. I have a 7.4 inch ATI balancer and I think I'm spinning the blower at like 20,800 rpms. the hottest I've seen it get is 161 F. this is on my 6.0 LQ4.

I put an M90 gen 5 on my 6.0 LQ4 in my 1982 S-10. I'm still having belt slip issues.

Will the nv1500 from a 4 cylinder s10 bolt up to the 3800

Great video! Thank you. Question - is it bad to run too large of a pump using a return-style fuel system?

A lot of people dont know that back in the day Ls engines werent cheap and everywhere, because all the junkyard units you can grab for a few hundred bucks were still on the road lol. And i did this similar style build in 2006 when i drove my 98 v6 camaro with no oil in it. It was winter, i slid off the road and a branch went all stab happy on my oil pan😮 So i went to the local yard with a shopping list and i got the L67 heads, intake, m90 mighty weez, and shoved all the sensors / injectors into my pockets because the brole struggle was real back then. So my short block was being rebuilt while i tried to figure out what the hell i was going to do for an intake elbow as i didnt want to cut a hole in my fire wall and have the air filter where my radio was. Then i remembered that Australia exists and their Holden rwd cars used the l67 with an intake elbow perfect for my purposes. Now this was asi said back in the day but ebay was a thing and the internet in general allowed commerce between continents so youd have thought finding a used intake elbow from down under would be relatively easy buuuuuttttt noooooo. It took months to find one and then work out how to get it from the land of all things dangerous and or poisonous and when it finally showed up it was cracked and just a PIA. So i took it to a local welder who was able to zap it and make it not be a giant leak. And just as that was done my short block was also done. So with refreshed heads, a smaller pulley, and an OG megasquirt i set to making my 3.8 dreams come true 😂. All said and done it made 302 hp at its 16in tires, after having demanded its tribute of about 5 months of my life and way more money than most 5 or 600 hp junkyard ls builds do today. Torque was good to at 338lb ft and the T5 transmission never even blinked outside of me smoking the original at the time 98k mile clutch before the swap. Its been so long that im pulling the motor just to freshen her up and seeing what i can do with the supercharger as the eaton huff and puff is about maxed out and ive since started building speeduino ecu's which beat megasquirt out in every measure i care about including how powerful the hardware is. So yeah cool build sorry for the novel butni broke my leg and im a little vored lol

Wowww that's loudddd

What engine mounts?

Were you on Fullthrottlev6 back in the day? I seem to remember this project on there back then.

Australia had the 3800 SC in the Holden Commodore base V6s and were rwd

I have just come across you video about the issue I am dealing with now. So I connected Pin No 17 on red connector to my vintage air compressor on my LS swap. I made the changes as well in the hptuners as indicated in this video. So I turned on the AC, the status of “ AC Requested” became Yes but the “Active AC” was showing”NO”, and the idle rpm did not bump up at all. Any idea why the idle rpm remained the same and why the AC mode did not get activated. Thanks.

Verry nice explanation done, thanks for the help😊

NOTE 2:20 part of vid.

You earned a sub from me the second you mocked the 79 owners 😂

Now i know why my car is cutting off Thanks

3800 need to be in everything really

What is that that's bolts to the supercharger that's under the plate ? What did you use for the bottom to bolt to the heads ?
