Was boosting 25psi on a Td05 20g. Got to top of third gear and lost power and felt a stumble....boost leak test revealed this.

So...some of you old timers that have seen this thappen before could you please help me answer a few questions on this? I've been reading around and others have had it crack, but never gave much information on their possible solutions.

1.) Can this be welded on the car (it is next to the fuel rail and stuff so I would say no unless you have balls of steel)??
2.) I'm tuned on ProEFI, but don't do any of my own tuning. If I take the SMIM off myself, have it welded, then put it back on, will I need a re-tune? The car literally JUST got tuned a week prior to this SMIM cracking.
3.) Will it even be worth it to weld this or is it now prone to more cracking? Would the wiser just go back to stock IM...I know it flows plenty for my power level...but it doesn't look nearly as nice in the bay as the SMIM haha.

don't worry, he jb welded it :ohdamn::hellyeah: and he didn't say anywhere the brand of the manifold so it's obviously ebay. he posted in his journal earlier

I do watch this thread (you know since I created it) so you could ask me if you have a question to my thread, instead of refer to me as "he" and take jabs at me for being resourceful.

Regarding JB weld use: I have to get by until my tuner/welder opens back up after the holiday weekend (I'm going back to 1000cc at this time too so getting it tuned again). I think letting ppl know you can get by for a few days on a $6 tube is useful info. Considering I hold 30psi on a boost leak test consistantly and have the car tuned way down from that and running perfect AFR's/EGT/IAT's/Timing.

Regarding the manifold: I indicated it came with the car back when I made the purchase. It doesn't have any signature on it as to what brand it is. It looked and felt like a good piece to me and every single other part on this car was a top name-brand part so I didn't have any reason not to run it....til now that is. So leave my low hanging fruit to me if you don't have much useful to add please.
