We are upgrading this product with a higher grade stainless. Out of the many many Mini-Mani manifolds we have made, we have ran into issues a couple times with manifolds cracking at the turbine inlet flange and we have decided to use a higher grade stainless steel to combat what I believe could be heat issues with the standard 304 stainless steel most people use to build turbo manifolds. With the small nature of this manifold, the heat has no where to go compared to longer runner manifolds where the heat can be dispersed easier. We will now be using grade 321 stainless which has a small level of titanium in it and greatly increases its capacity to handle heat in general as well as heat cycling. This increases material cost significantly but on top of that, material costs have risen to the point where we needed to increase pricing. We're sorry but when materials become more expensive and harder to obtain due to the direction of our country, prices rise. We are also exclusively recommending the use of a Turbosmart 45mm wastegate from this point on. This wastgate is readily available compared to Tial and is more compact which means a lot for this manifold due to where the wastegate is located.
The AC and PS compatible (for select chassis) H22 mini-mani is a great solution to the typical log manifold. While this manifold may appear to be simple, its really very detailed and specific in order to stuff it in the same volume of space as a log manifold.
If you don't have a local fabricator, you will likely be interested in the hot parts kit. This kit includes the downpipe and dumptube. However, I will need your turbine housing. This manifold is restricted to T3 or V-band turbine inlets. In most cases, for prelude and accord chassis, a traction bar is required for turbo applications so please be aware that this kit may only fit with a traction bar.
We sell and recommend the Garrett G25-550 turbo for most applications and the 660 for those wanting to max out the capabilities of this manifold. While we are fully convinced the manifold will handle much more power than that, its not the design intention. For wastegates, we exclusively recommend the Turbosmart 45mm Hypergate due to its compact size and availability.
