used here anyone this manifolds as an T2 or T3 ❓
TlIf ivread he discription ,it will be an good stuff,but hold it in real too🤔❓

I will maybee use one t2 with gt2860/2871,
Or an t3 with gt3076 turbo,and highboost.

What do u think how much can this manifold handle❓
The most cheap iron welded manifolds broke ,after few hundreds of kilometers/miles..

I i bought this or is it ****?

I need a good and cheap t2 and t3 as an sidemount like this.

Thx guys

 

Lots of info already on the forum about these. Search for "tacotaco" manifold

 

Yeah I use that. Its likely not the most efficient out there, but its seems durable and gets the job done. You can see by the times in my signature that it works good enough.

 

You use that 1.8 eBay tacotaco manifold with those times? What was your downpipe solution? Custom? Do you have a build thread?

 

Yep. All custom exhaust. Its all mild steel and welded with hf welder so its ugly junk, but again just like the manifold, it gets the job done. 3" out turbo for about 12" merging to 3 1/2" to just in front of rear axle, then back to 3" to rear of car. Closest I have to a build thread is https://www.miataturbo.net/build-thr...exhaust-98666/ You can see various changes over the last couple years and progression in performance.

 

did you need to weld the hole shut that is for the heat shield that sits on top of the flange where the turbo mounts?

 

I did not use the shield and did not weld the bolt holes. the bolt holes did not penetrate to inside of manifold.

 

FM or Begi downpipe should work with this ebay manifold.

 

Okay good to know. I saw a video on YouTube of a guy reviewing this manifold and the hole went all the way through the manifold and he said it would need to be welded so just wondered about that

 

some might go all the way through. Mine doesnt. If yours does and you don't use the shield and you cant weld it then just put a bolt in it, Not a big deal.

 

Got mine today, that hole doesn’t go all the way through but the turbo studs do. What did you do about that?

 

Do nothing. Mine's the same. Bolt om turbo and enjoy.

 

I ran that manifold on my 500whp ebay compound turbo setup. Worked well.

 

Hell yeah that’s what’s up!

Good to know! Thanks for all your responses and help with this man

 

Hey man, just wondering did you use an external wastegate or did you put something over that flange. Mocking up a wastegate right now and I really don’t see how I could route a pipe off the wastegate. It’s basically pressed up against the block or the exhaust housing

 

Not sure what wastgate you're running but if the exit pipe you have for it points straight down and has too wide a radius you will have to cut the flange off, make a pie cut to tighten the radius and angle more to rear off car rather than straight down and re-weld flange. May even have to heat and dent in the outer radius of pipe some as well. If you are using the style wastegate I think you are there is enough room if you have the exit facing block for a tight radius elbow facing rearward and down.

On mine I welded a 1" drop pipe with a new flange to rotate wastegate exit 90 degees to face rearward since I originally ran wastegate exhaust tied into downpipe, but now I run open wastegate pipe so I would have done as described above if running open wastegate originally.

My best advice I can give though is if this is your first time building a turbo system would be to go to harbor freight and pick up a cheap flux core welder, angle grinder with both grinding and metal cut off wheels and maybe a dremel tool. Since you are building from scratch you are going to find all kinds of things that will need to be cut, hammered, removed, butchered and welded as you progress with this project.. There will be a lot of things you will have to cope and figure out on your own as every custom project is different. The easy button is to buy a complete and fully engineered turbo system, but even then you will usually have to make some modifications to your car for fitment.

 

Thanks for the advice. Also, OP sorry for hijacking this thread. This is the setup I have mocked up now. CHRA still needs to be clocked and real mounting hardware. But this is a rough mock-up of the setup I’ll be using in the beginning. (if the wastegate pipes fit) I also have a good friend who welds that’s doing a few things for me
