i would have left them all triple hole with the stalactites and stalagmites, tornado

[@BlaserBuilds]

Golf ball effect... maybe... lol.

[@LynnTwinCustoms513]

Time to get a Bridgeport mill and start a Blaser machining and fabrication shop hahaha

[@alexanderjones6383]

This is THE content I'm here for. Thanks for your contributions to the 4200 world. You best believe I've one of these intakes sitting on the shelf ready to make this happen.

[@J-Whit]

The A1 bottle got me 😂

[@BlaserBuilds]

Haha.

[@HaNg_ALL_ThE_tRaItOrS_hiGh]

​@@BlaserBuildsGIVE IT THE SAUCE!

[@brenthinton6855]

It's really too bad that other people don't like the welding parts. I just found this channel and welding is the thing I'm most interested in right now. Anyone can turn a wrench but fabrication is an art. Keep up the good work my man!

[@gravely1000]

being aluminum, I think I would have tried a jigsaw with a metal blade instead of that sander cleaning up those holes. Maybe clean up with the drum sander after cutting the tips off. Just a thought. I even cut up to 3/16 steel with the jigsaw and metal blade if I want a nice crisp edge instead of the plasma cutter. I also bought one of these air powered metal router to take the edge off and it makes for a nice cleaned up beveled edge for welding if you are going that way. Keep up the great content. Even brooks is posting again. and thanks for the nivlac57 tip. Glad his dad is healing up! Now I want to do a six in a row for one of my G body cars. Fisrt I have to get the bent six together and going .

[@georgef1176]

Great job! A Barra intake would be longer probably be a bit easier but do this kinda mod your doing. Hopefully aftermarket will step up on this motor.

[@hadlock]

Word of advice maybe include a one or two sentence description of the project overall and what you plan on doing in the video. This is a super cool project but narration could use additional direction. Cheers great project great video overall

[@Wreckedekcoupe]

Time to put them into mass production. 😎

[@Wreckedekcoupe]

Those shavings brother! Im pretty speechless with this one ryan. You stepped out the box and some. Bravo!

[@HaNg_ALL_ThE_tRaItOrS_hiGh]

The lathe opens up so many possibilities! This is gonna look so sick. It'll look good! No need to tell yourself it will!🍻🤘🏻

[@d.collier_8280]

Looking forward to seeing this thing fire up

[@emccolly]

Looks sick!

[@xozindustries7451]

Great work, You could always cut the 2JZ manifold in half and lengthen it to make it the same length as the 4200 so you can go straight with all the velocity stacks.

[@BlaserBuilds]

I did consider that, but didn't want to add a random section in there.

[@bigfoot355]

This is awesome!

[@jackpike9337]

Looks great

[@adamlambert3892]

Nice job

[@LoudPedal66]

Damn right, brother

[@juicebox853]

You're a worker. I would be scared to take on some of your projects. Takes some serious motivation and resolve.

[@BlaserBuilds]

May not be smart, but can't say it's lack of effort, lol.

[@steventurner476]

All sauced up

[@BlaserBuilds]

Yolo!

[@Rebel635csi]

Awesome work, but I gotta ask, why not just start from scratch? The plenum can be made from 3” mandrel pipe bend for the end and straight pipe and flat sheet metal alu. It would have allowed you to make the manifold to fit the 4200 better instead of working within the limitations imposed by it.

[@BlaserBuilds]

Part of it was that it's already been done that way. So instead of just copying what people have already seen. I tried something different. And this already had provisions for throttle and vacuum lines build in.

[@crazysvt03]

I've never heard a man so excited about a sloppy fitting 3.5 inches 😅

[@BlaserBuilds]

Six*

[@gregpadberg1402]

I figured you would either burn out a drill, or get kicked in the gut when the 4" hole dozer finally bit in.

[@BlaserBuilds]

Just rested it on with real light pressure.

[@scotttimpany2845]

Dude! Hilarious.

[@MartinBorn]

Am I missing something or is the comparison of surface area between the throttle body and intake ports rather irrelevant because not more than two ports will consume air at the same time. Which means that the surface area or air flow through the throttle body is twice as much as the intake ports drawing air at any given point?

[@nooch8it197]

The intro was lit or fire or something......I'm old did I say it right? For real that was funny!

[@BlaserBuilds]

🤣

[@davidconley3610]

👍

[@bartpang]

I would have just used an 1 1/8 hole saw for the outer holes and jigsawed the center. Plus I would have just used a 4" piece of tubing for the plenum instead of the 2JZ intake.

[@BlaserBuilds]

I bet...

[@MegaSpool]

Good shit man, good shit. Do you think cutting the plenum in half lengthwise and adding a section to get it long enough for all the runners to be straight shots would have been feasible now that you have it all done? Or not worth the extra effort to save the angles on the front and back runners?

[@BlaserBuilds]

Thats definitely an option, and I considered it, I just didn't want the look of having the added section.

[@MegaSpool]

@@BlaserBuilds yeah I don’t blame you there, I probably would’ve went the same route. Awesome work man, I look forward to seeing the progress.

[@FredAllenBurge]

Cyl 1 air flow seems questionable but I'm sure it'll do ok depending on how hard you push it. Are you going for big power?

[@BlaserBuilds]

500-550 ish.

[@Matt-hz1oh]

How are you going to do the fuel injectors and rail? Looks good man.

[@BlaserBuilds]

Injectors go into head. No need for them in the intake 👍

[@Low760]

There's a plenum available for the Barra, maybe that could be tested given the similar capacity and breathing?

[@BlaserBuilds]

There is one out there but it's higher cost by itself than this whole build. Then still have to figure out throttle plate, runners, flange etc. Could easily have $700+ into it. This cost me $238.

[@Low760]

How did you come up with the bandsaw mount for the portable saw?

[@BlaserBuilds]

Swag table.

[@WelcomeToTheMadness]

Hold on, were you A21 Bravo or something like that?

[@BlaserBuilds]

Yes. I changed a little over a year ago.

[@jar895]

Next time drill pilot hole then put hole saw on.

[@tjs_welding_and_fabrication]

Do u have an svg or dxf file for the flange.

[@BlaserBuilds]

There's DXF on the wiki page

[@tjs_welding_and_fabrication]

@BlaserBuilds I can cnc plasma cut a thin test sheet made of 16 or 14 ga steel, it is yours if you want one. Just a few bucks for shipping. I was able to download the dxf I hope the dimensions are correct.

[@marlonrodriguez6667]

Love the creativity! My brother actually messaged you on Instagram. Seemed like the best place to reach you on. I have a sweet 4200 Datsun 6 speed build I'm working on, and could use some insight on what the next steps are.

[@BlaserBuilds]

I deleted Instagram app so haven't been on there for a while.
