Looks great!
Certainly inspiring me to want to build another...

Are you planning on adding a brace underneath from the engine block up to the turbo flange?

Looks great man! wish i had the space, or a garage for that matter, for a welder.

Quit with the pissing match! It is a know fact that TIG is the way to go for a Turbo manifold. I would like to cross post this thread to the Fabrication thread on Honda-Tech, it would be FUNNY.

I know from experience that if I am going to do anything, I am going to do it right!

Correct, but a by-product of Horsepower is often increased back pressure which causes even more havok at the insane turbo manifold temps.

it would be funny because all the responses would be:
"fuck"
"gay"
"i like dick"
"suck me hard"
"omg, i want miata dick in my mouth"
"fuck my mom's calling me, brb guys."
"omg, does that guy have a wife?! i wish I could talk to girls let alone marry one."
"SoCal rulez!"

I migged my manifold. Got about 5k on it. Hasn't cracked yet.

Also you forgot:
"CRX"

Oh noes. Please continue to grace our forum with your honda knowledge and do not get mad at us. We obviously are not equals as you have VTEX0r and better weldZ! Our simple forum lacks any knowledge of horsepower and backpressure :(

Mia, aside from this joker, it looks like your doing good and learning alot. Keep up the good work.

Too Funny...

I was probably one of the pioneers (Working with Rick S and Danny G) in making over 300, 400 and 500hp with a Mazda Miata, swapping/mating a Turbo II Tranny to a Bp engine, installing an RX7 Turbo II diff into a Miata, using a Honda Intake manifold on a BP, and a Civic rad in a Miata. I've been around the Miata community for years and used to be known as 450hpMiata and owned Turbomiata.net website.

I have a 700hp Honda Drag Car, and my 2000 Mazda Miata with FM everything (Got it that way, and I am sure I will start changing a lot of the FM parts). I'm not really a big fan of Honda's, but I was having a very hard time finding sponsors for a Mazda Miata Drag Car, and the Honda was a lot easier.

I'm certainly not new to this shit. The only reason I mentioned the Honda-Tech forum is that their Welding/Fabrication forum often has absolute works of art manifolds posted, but also some real fugly stuff.

The poster get a :bigtu: for attemping this, but the welding choice and finish was what I commented on.

Do an archive search of "mig manifold" and you'll find a number of threads where many of those people who you say make work of art manifolds state that a mig'd manifold can most definitely be made to stand up to the demands of a turbo application.

TIG is way out of the picture for the large majority of......everyone..... because of the sheer time it takes to learn to do it well. I gaurantee that someones first MIG welded manifold would hold up better than their first TIG welded manifold given that they have had the same amount of practice on both.

JB Weld FTW.

I will give you that TIG is harder to learn and MIG is easier. MIG is also stronger than the Flux-Core welding. It is hard to get great looking penetration with a MIG. It usually comes out ugly when you add in more heat and wire.

I think you should all just arc weld your shit. With big fatty 3/8's rod at 150 amps with nothing but a pair of sunglasses and latex gloves.

I love that stuff, just not for Turbo Manifolds :)

i decided i hate it for everything, acutally.

Flux core welds will be more porous, I will agree with that. The fact that its his first manifold though, I'd say its something to be proud of.

In the future he can easily upgrade to MIG by just buying a new gun that can use gas and a bottle. The gas just won't run through the machine, but if you have a cart to put everything on it doesn't really matter.

holy toledo...

yeah, i've done plent of searching. 9 times out of 10, 2 passes with flux core is plenty strong enough for mild steel. I'll let you know after a few track weekends.

Thanks for the compliments to those that gave them, and the encouragement to those that blazed the trail before me.

Nice.

A question from the bleachers - it seems like having the 2 merge with 1 and 3 with 4 would make bottlenecks. Is the Sch40 big enough for 1.8L app that it's a nonissue? I guess no matter what it's gotta neck down from four pipes to one, just curious.

Please keep us posted on the durability. I go from complete DIY to complete BEGi kit about three times a day in my mind.

no bottleneck, floooooooooooooooooow!!!!!

Mig is stronger then flux core? Really? This has got me interested

Sure, because with flux, you have the goo fizzing and oozing all over, and with MIG it's just plain ole steel.
