Pretty red car

Back in the day I was a Weber side draft expert I had hundreds of dollars worth of jets choke tubes etc I had a 74 Opel Manta 2.0 with cam high compression pistons, I had twin 42 millimeter dcoe carbs with very long stroke pump rods no bog at all plus good gas mileage.

[@lakevanwyk7363]

The plastic bag flying around in the beginning of the video gave me so much anxiety

[@ToneScavenger]

That’s exactly the setup I’m going to do on mine. Great car!

[@petrsindler1525]

Weld a damn bung on the header and tune it with a wideband sensor. It speeds the process up. Sweet ride though. Never experienced a Weber. Converted mine to efi. But I do appreciate the good old ways of getting her done. Weber is a classy addition to a classy car. Sounds legit

[@RADPotential]

Yea that was my thoughts... but will just had his whole exhaust cerakoted so he wasn't too stoked for that idea. I have plenty of jets and we will figure it out quickly for sure!!

[@Dansyoung]

This brings me back to messing around with my 12a that I had a Weber 45dcoe on. Not going to lie, pain in the butt, I’m a fuel injection guy 🤣. It used to burn way too rich, massive headaches after working on that thing.

[@christianvillalta6464]

Damn miss carb 7’s , finally got around to buy a 79 with a 48 Weber …. First timer on this setup … but my gslse is finally done and garage queen now .

[@edlippjr]

dood - this is my car! well same exact model '79, mostly untouched. I so wanted you to work on it with me lol but I've got a local place that just managed to get the engine out, now we're at the tear it down stage - fingers crossed my metal is in good shape

[@willg125]

Update? Getting ready to tear into my first gen keg too!

[@djmtsu]

I don't hate Webers! Just never got the chance to use one of the several I bought! Haha!

[@GrizzlyGamerUSA]

Good thing I kept my emissions harness

[@latenightfups]

Nice 79’ with glass moonroof. The red is nice. The 45 Weber gives the car a great amount of pep. I have a 79’ stock with Weber and drove a 85’ gsl Nikki. Big difference

[@julianreece3595]

Excellent content as usual 👏🏼👏🏼

[@GabeDiaz84]

Amazing Bro, I just got a 1982 rx7 and I am totally new to it. The car does not run, and needs tons of work. So I will watch all your videos this week 😆😆 it has a 12a who knows what condition.

[@alexrodriguezrx7]

I think i am gonna have to fly you down to Houston to tune mine when i get ready here in a couple weeks.

[@wjweaver63]

Great looking car!

[@smokino9387]

I have an rx8 2004, but I end up watching all your videos anyway. Strange thing is, I was doing all this searches on rebuilding engines and took more then a week until one of your videos popped up in search

[@RADPotential]

What were you searching, I can add tags to them

Woah, that massive mazda sign is super cool! Must've been from a dealership?

Yes sir. I believe from the dealership in Columbia TN

Hello how did you manage the oil injection?

[@bitcoinworld6288]

...lol, that plastic bag though near the intake horns..

[@gavbellamy8434]

Super stoked

[@oscarvillegas2448]

Did you replace the original distributor as well?

[@oscarvillegas2448]

The original one it consists of points distributor

[@RADPotential]

We will be replacing that in another video coming soon!! And an alternator upgrade as well!!

[@austingage7209]

This might be a dumb question, but would this significantly reduce fuel economy over the stock nikki? I've got a bone stock '80 that I daily drive, making about 19 mpg combined. I'm looking to do pretty much the exact same setup as this video (45dcoe + RB exhaust), but probably wouldn't if my fuel consumption goes through the roof.

[@rucarnuts13]

I’m looking to do this to my 1984 RX-7. I bought an IDA 45 from Racing Beat. Any advice on the jetting, or should it be good out of the box?

[@luiscotto2790]

Question: bought a geo tracker has a 12a rotary in it starts but when I hit the throttle it chokes up the carburetor looks like the one in the video. But bought it on Amazon cheap. If I bought a racing beat intake and added a holly carb will it fix the problem

[@jeffphelan3177]

Eric - love the content! Question on your comment about the RB exhaust and header with the Nikki. I have an '82 GSL with a stock 12A and the RB header and exhaust and it runs really well. The exhaust just went on this summer - what should I be watching out for? Cheers!

[@RADPotential]

When you do have the header and a nikki carb. There are places on the stock manifold that need to be blocked off. That's all I was referring too. A good working nikki is a great carb to use.

[@travisgrover7163]

Old street port exhaust or a new one with the louder muffler?

[@RADPotential]

It's an old version that will restored

[@travisgrover7163]

@@RADPotential I thought it sounded too good lol. Any experience with the new Street port systems? I hear they are LOUD. Also any chance you have a Weber set up you’d sell for a stock port 12A haha

[@RADPotential]

I haven't been around too many new ones. Go check out the Holley Sniper EFI car. That one has a newer RB street port. It's not too loud. I dont have any parts for sale

[@angelmanuel7381]

U need to learn how to accelerate Mazda engines plus u have to check jets and timing
