What 1JZ manifold are you using?

chinamanifolds blow and 100% sure will crack unless you reinforce the runners and reweld everything. I personally dont want to bother with all that and am looking into a cast unit. They are generally cheaper and MUCH stronger than any of the CHEAP tubular setups, not talking about the good tubular setups here.

Buying a quality manifold just buys you more time, stainless with crack because it's stainless. I am running a chinamanifold and when I put in the new turbo I dye checked everything and it was fine. I'm not sure how long the previous owner had run on it.

boost logic, drewgo, and almost everyone else has their manifolds made in china. When was the last case you heard of a JZ manifold cracking ???

Drewgo's manifolds are made in china to his specification, their already reinforced, and have a better location for the wastegate.

I rather page $130 or so on ebay and weld the 2 rod supports like he did.
