my mani is done check it out

[DRIFTEADOR]

bleh, those manifolds already crack with no modifications so if it does crack we'll just blame ssac

Hahahah funny how 180sx tries putting Sanioll in his place but then goes eats his own words by critiquing 214kka-et240sx himself. Some people should take there own advice

My question is the guy used aluminized piping for the extensions, would that melt under the temps of the Turbo??

[C-Kwik]

I really skeptical about how it will hold up. I mentioned in the previous thread, all the heat related problems that can occur. Tehre are plenty of things you need to do to reduce the chances of cracking with a manifold made on one type of metal. Using several different types within a single manifold is asking for failure. I'd actually give your ghetto-fabulous log mani a better chance of survival than this. It certainly looks good for fitment. I really hope it works out for you, but I'd hold no expectations...

sanoill: while I am generally the first to argue backpressure, this isn't a manifold designed to try and provide a perfect backpressure scenario. For the most part, it seems each runner maintains the inside diameter so there should be little effect on backpressure from one runner to the other. THe only other factor then, would be the backpressure the turbo itself provides and perhaps the exhaust system behind it. But neither of those will be affected by the manifold's design. The way the #1 runner meets is directed at the collectoris about the only thing I would question froma flow standpoint, but the manifold will direct the airflow into the turbo as intended and do a decent job. My only gripe, which I previously stated is the mani's longevity.

I give props for trying it. I would have tried to source all stainless parts if I were intent on doing it though. To all their own I guess...

No.

Aluminized piping is simply steel (not stainless) that has a coating applied like galvanization.

I do think there will be problems due to the differential in materials (cracking due to different rates of thermal conductivity).

[WDRacing]

Yep, different materials should not be used in an envirnment where they will expand and retract at different temps. Hopefully all works out well, but I see things cracking in the future.

But like everyone else said, big props for going ahead and doing it yourself. You'll only get better from this point on.
