Miata swapped MGB // 4age ITB MGB

[@davidsingleton794]

Love the nostalgia of the ITBs!

[@drewbarker8504]

What a fantastic and appropriate swap! The ITBs and exhaust note are rad!

[@PeelePowered]

Just gotta figure out the issue with cylinder 3 not firing.

[@drewbarker8504]

@@PeelePowered Maybe something going on with the throttle body? Like fuel delivery or a blocked jet?

[@PeelePowered]

@@drewbarker8504 it has fuel and fire. It either isn’t getting enough air, or there is a weak signal. Imma mess with it soon

[@drewbarker8504]

@@PeelePoweredtotally forgot about that. I’ve blamed ignition on fuel problems before. Maybe plug, plug wire, coil. (My problem was a Pertronix Igniter unit that got smoked 😂)

[@PeelePowered]

@@drewbarker8504 I’m thinking it may not be getting enough air. With the throttle plates closed cylinder three shows 50psi compression while the others are around 90-100psi. With plates open compression is 150 across all 4

Damn, this is awesome. Want todo this to my 79 GT.

[@louiejonesponation]

Nice swap. If I ever got an MGB, I’d swap a 5.0 Rover V8 from a TVR Chimera.

[@PeelePowered]

Sounds expensive for a MGB 😂

[@Mattlawton-ft6ew]

And it looks so right in there 🤌👌😁👍

[@humanbeing4165]

I approve

4AG ITBs, on a Mazda BP18, IN AN MG? "HOW MUCH FOR THE CAR"

[@PeelePowered]

That’s exactly what it is! And right now she’s not for sale. Unless the offer is something I can’t refuse

[@jakepearson2395]

That’s the Mazda engine not a 4age which is a Toyota engine

[@PeelePowered]

Thanks man…. I built this engine. I know it’s a Mazda bp18. If you look closely you’ll see 4age ITB’s hanging on the side of it…..

[@guitariste47]

I like the front spoiler/ lip on thé car. do you have more power? I have a 2004 nbfl 1.8 mx5

[@blackhatch46]

You can tell its a miata engine because of the lifter tick hahaha

[@PeelePowered]

💀😂 100% Luckily some thicker oil cleared it up now lol

[@chevybarboza]

Did you have to mess with subframe I'm asking because I might do this swap myself

[@ThemeanRippy]

I am working on the K24 with Miata 5spd tranny. How difficult was this etc. In the beginning stages like just purchasing stuff. Wondering if easier to switch gears and probably cheaper.

[@PeelePowered]

Honestly the hardest part was mocking up everything to make engine mounts

[@BevanFarmTexas]

Did you use the factory Miata engine wiring harness?

[@PeelePowered]

Yeah man!

[@BevanFarmTexas]

@@PeelePowered just starting a swap on an MGB GT 👍

[@babyGOAT..]

What exhaust is that?

[@PeelePowered]

Stock 1.8 Miata header cut at the collector to a 2.5inch vband

[@reed-xd8zx]

Why the white smoky exhaust?

[@PeelePowered]

Cylinder three is down. Has compression, spark and fuel, but only spits and backfires on cylinder 3. I’m starting to think there is a weak circuit causing this strange gremlin

[@juliuscaesar6746]

I plan on putting a bp4w in my NA and doing an ITB setup. She looks good and sounds great man!

[@PeelePowered]

Definitely a cool setup! I think my next project with a BP will be supercharged. Havnt done that yet.

[@juliuscaesar6746]

@@PeelePowered I definitely thought of a supercharged BP as well, would be a nasty setup and the instant torque would be great

[@higg1n5]

If you can swing it I recommend the Hummelink ITB kit. I love mine

You got some cams sat in that? idle sounds a bit lumpy like it’s got some

[@PeelePowered]

No. It was actually only running on 3 cylinders. Cylinder 3 ended up with 60psi.

[@mohamadhamad770]

@@PeelePoweredyikes, did you figure out why that cylinder was down that much psi?

[@PeelePowered]

@@mohamadhamad770 Bent valve from the previous owner of the engine

[@mohamadhamad770]

@@PeelePowered did you end up fixing it?

[@PeelePowered]

@@mohamadhamad770 back to 150psi across all 4 now. But still cylinder 3 dosnt want to run. It has fuel, and spark, and the engine is in time. So I’m starting to think we have a weak circuit, or the ECU is faulty. Cause really it should be running

[@Beanie.910]

Thats not a 4age

[@PeelePowered]

No shit. It’s 4age ITB’s on a bp18
