miata turbo manifold

I've found a T3 turbo in a junkyard with no damage whatsoever, no rust, and no play in the interior of the turbo. However i've been looking around for a t3 miata turbo manifold and was wondering whether all the exhuast pipes on the manifold leading into the turbo should be the same length or not, i've seen them both ways, but was wondering if one gives better performance than the other.

Parts for the miata, i would also try racingmazda. Not as big a company as flyinmiata but still quite reputable and heralded by the miata crowd.

The one where all the tubes are the same length are called tubular.




The other type is a cast turbo manifold, usually cast Iron:


Neither is really better than the other performance wise, as most of the exhaust gases will be backed up at the turbo anyway.

The problem wih tubular manifolds is that they arent nearly as strong as the cast manifolds, and are more likely to crack and warp because of the excess heat generated by the turbo.

yet, the tubular manifolds somehow help spool turbos up a bit better than the normal cast ones. stock cast ones also have some more restrictions, i know cuz i have my stock cast one on the supra. still, i like mine. gonna have the T04 flange modded into it and gonna paint it so it looks nicer.
