Turbo Manifold

My memory must be getting foggy from old age but was there ever a cast turbo manifold for the 3sgte(gen1) that still utilized the single entry ct26 turbo flange other than the factory piece???

 

Will,

I got a couple of questions regarding the STR manifold you are using...it looks big, alot bigger than the stock piece, how much bigger would you say this is compared to the factory single entry manifold ie. internal runner volume, is there a flow rating for this manifold?

 

Theres also the Turbonetics and the replica - both cast design with a T3 flange but adheres more to Toyota original design then to the log style manifold that STR manufactures...also appears to have smaller runner volume when compaired to the STR manifold as well.

Wastegate port location aside, what made you decide on this particular design?

I asked a well known distributor there opinion on all three manifolds but I would like to hear the opinion of an actual user.

 

I dont particularly like the wastegate location on the Turbonetics manifold either but I plan on using a IWG turbo anyway so that port would be blocked off.

Trying to find a S252/S256 in a .58 - .68 AR with extended tip has proven to be difficult and was wondering if the smaller frame turbo would see full boost below 3300RPM with the log style manifold.

What kind of lag are we talking about here Will, at what RPM do you see full boost?

These manifolds are only a second resource as I want to retain the stock look and CT26 turbo flange so as to utilize either a LIPP BOSS JR. or Turbonetics CT26/T3 turbo although finding the A/R for the later has proven to difficult as well. However assuming that the Turbonetics is an identical copy of the discontinued HKS Sport turbo upgrade for the 7MGTE than it uses a A/R of .63

Sourced out a ex. TTE ST165 exhaust manifold so hopefully that pans out, which BTW is the ONLY manifold other than stock that still utilizes the CT26 turbo inlet flange.
