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.
basupra said: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.
'94 T-62 (SP70 soon)
'91 Stealth TT
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:As far as wastage selection, you've got:

Grant said:Wow, that is a completely different manifold from what I have. Are you sure that is for the MKIV? If so, it must be something new.
This is what I have:
That sure looks a lot like this "HKS" manifold. Does yours have the "T" cast into it anywhere?Grant said:This is what I have:
Hey Grant, I don't want to say that the manifold is for the MKIV for sure. I was just passing along some info. I was told by the rep. I felt that what he told me was kinda "SUSPECT" anyway because every pic I've seen of a cast manifold looks like the one you have.Grant said:Wow, that is a completely different manifold from what I have.

ATLSUPDAWG#2 said: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.
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:You can tell that manifold is not for the mkiv because of the evenly spaced runners of it. The mkiv has a larger gap between the 3 and 4 exhaust port. They should make one like that though, looks nice for a cast peice.
Looks to me like the only thing Turbonetics is making is copies of other peoples stuffATLSUPDAWG#2 said:Well it's obvious they have the capability to make a decent looking manifold like that.
