Turbonetics sells one for around $600-650. I have asked in the past about this same subject on this forum but no one seems to know anything about them.E-mail me to let me know any info. Good luck.

I've got the cast manifold, with a small shaft T-62 turbo, with Greddy 3-row, SP fuel system, VPC, ect... Dynoed 567 RWHP at 25 psi with the 62, with about 11.1 a/f (fairly rich), no tuning, and was getting spark blow-out up top. I just got my SP70 yesterday (thanks Marko and Lar), and will hit the dyno up soon. I am under the impression that this manifold is NOT nearly as restrictive as most people think. I guess we shall soon see!
With that little of a turbo (the 62), and making that much power at only 25 psi tells me that it is not that restrictive. I will post my #'s when I get them.

I called Turbonetics on this to get a price and it ran for about $625. I also asked what HP the manifold was good for and he stated "about 700-750 HP". My last question was, "is this a log style manifold?" and he replied that it is not a log style but rather an equal length tubular manifold similar to what's in their catalog. Attached is a scan from Turbonetics 2001 catalog of the header. This is what I was told.

A solution you might also want to consider if you want to use another brand of wastegate is to fabricate some sort of small stand-off or "mid pipe". You would have a flange machined to mate to the flange on the header, weld in a small (1/2" long) stainless tube and weld on another flange on the opposite end machined to fit the flange of the wastegate you'd want to use. Just an idea!!Grant said:

Thats the manifold I have on my supra, my mk3 that is. That is the copy of the old HKS manifold they made for the mk3--
Well it's obvious they have the capability to make a decent looking manifold like that. I too can't see why they produced an eye-sore like that log style manifold for the MKIV and not one like in the picture. AND, for $600ish they'd probably push a lot more if they did. Anyhow thanks for clearing it up. I knew it was "SUSPECT", I just knew itHoustonSC300 said:
