My turbo MX-5
#124
First race went as I guessed. Nothing work
Brakes went first. I get max 2 laps and after that it was just praying in every corner that they work. TSE 11.75” BBK are on the way soon as TSE have time to send it..
And then the intake manifold cracked again :(
It seems that my support brace and “runner ribs” didn’t work. There’s have to be something wrong with the welding it self...

Congrats on the build - I'd also consider the intercooler pipe setup. Think about how little stress is actually on those welds... That manifold can not weigh that much. Try some Vibrant hump hoses and make sure there is plenty of room to flex.. Also what engine mounts are you running? Might be quite a bit of play when you're in boost, especially between shifts.

IM is fixed again. Next time it cracks I’m getting OEM flat-top and build SS intake manifold next winter (like hf-mx5t here: https://www.miataturbo.net/build-thr...e3/#post548391).
new wheels (sorry 'bout the dirty car)
6UL 15x9 with 205/50 Federal 595 RSR
plus I made some quick wheel alignments
FR camber -2. Toe 0.0
FL camber -2,1 Toe 0.0
RR camber -1.6. Toe ~1mm
RL camber -1.6 Toe ~1mm

Dat bov noise. The ricer in me wants to block off the bpv on the efr and run one of those. The racer in me remembers that the efr bpv sounded almost exactly like that when I ran the car with the hood off on the test drive.
Sucks about the honda mani. It looks like a classic weld fatigue fail from a stray crater or cold crack. At least it wasnt a WWII ship that broke in half just as it was leaving port on its maiden voyage from the same issue. I think if you just cleaned it up more you'd be fine. BUT with the contamination on it already I dont think the current one will hold up if it gets rewelded. Because that **** is a pain in the *** to clean up.

I don’t think there’s any wrong with the welding itself. It’s just that the Honda mani and miata flange is totally different aluminum casting. It’s really hard to get that stuff stuck to the Miata alum casting. It just “repels” the welding material. Trust me, we have tried everything and my buddy is über pro welder
I was consider making my own flange to the Honda mani but then I read from the “Honda IM” thread that someone has broken flange off from the Begi alum IM manifold as well so… I guess it’s safe to say that only real proven solution is SS
On a different matter, my TSE BBK package has arrived to my sea container in Houston. Now it’s just waiting it to travel 5165 miles to me.
