Here are some pictures of our prototype 3″ o2 housing. This is a true 3″ o2 housing with 2″ dumptube and is intended to be used with our turbo kit downpipe or your own modified downpipe. More detail will be available soon. Pricing is expected to be about $390 for the o2 housing and the downpipe currently sells for $282.
Here’s another manifold that I’ve been wanting to build for a while. It’s not for the ultimate horsepower junkie but intended to provide a very wide power band, lower torque peak, and improve low RPM response & power. Auto-X, Road Race, and street car guys may find this manifold to fit there particular interests very well. It is built off of our EVO T3 fixture and fits up exactly the same as our extremely popular manifold T3 Manifold.Price is the same as our standard T3 manifold and is available for order immediately.
As usual with our product the attention to detail is the highest in the industry and the quality is second to none. One feature of this manifold that I feel makes it stand out from “the rest” of the small runner manifolds is the transition from the larger oval cylinder head port to the smaller diameter primary of the header. The entry to all of our headers feature the same large oval port size. The transition from this large port size to the smaller primary is achieved using a unique process to create a proper transition from the smaller runner to the larger port size. This is just one example of what makes our manifold stand out from the rest of the competition. Most companies offer an oval to round transition machined in the head flange. This transition takes place over the thickness of the head flange which is typically a distance of 1/2″, this creates a radical transition and is not optimal for exhaust flow. One manufacturer’s entry into the runner is actually SMALLER than the cylinder port and most definitely robs power. Cutting corners such as this isn’t acceptable in our eyes to make manufacturing easier/faster, or to make a few extra bucks.

Sean Ivey brought his EVO out to Atco last night to make a few passes. His previous time at the track he found the clutch to be slipping and addressed the issue for last night. The car is a pretty basic build and is very much a near complete street car weighing in at 3050lbs. It is using our standard Divided T4 Manifold with a GT4294, E85 fuel, AWD Motorsports driveshaft, AMS intake, a few AMS lightweight goodies, has a full interior, all functional glass, and of course features an IVEY Tune on a HKS FCON.

I’m a little late in getting pics up and most of you have probably seen pictures of our EVO Replacement o2 Housing already. I thought I’d throw some pics up real quick of the 2nd prototype that we built and add a quick blurb. This is VERY similar to our production unit and will have pictures of one up shortly.
People have been asking for this item for a while. I heard them but pretended not to hear. Until the latest revolution of upgraded stock frame bolt on turbos I thought messing with stock frame turbos was a futile exercise. While I feel these stock frame turbos can not provide the power and acceleration of our Shearer Fab Turbo Kits, they do fill a nice niche for those looking to make a bit more power than the stock turbos can provide. This is where our new replacement o2 housing comes into play and provides a nice solution to add up to 30whp to your bolt on turbo. After seeing some of the junk o2 housings that have been marketed so powerfully onto the plate of EVO owners I thought some might appreciate a properly built piece that is built to perform, constructed properly and won’t fall apart, fits properly, and looks good. This o2 housing in constructed ENTIRELY of Stainless Steel and brings the quality to the table that you expect in every Shearer Fab product.
The EVO o2 housing presented a couple unique challenges to build it properly. First was the tight confines between the turbine outlet and exhaust inlet flanges, there was not much room to make a proper bend and left zero room for error. Second was the large and oddly shaped outlet port of the internal wastegate. The first issue was easy to resolve. The second issue was addressed by having a super sweet turbine outlet flange made that has a 3d machined transition for the oddly shape internal wastegate port. The other o2 dumps commonly feature a simple round entry hole into a 1.75″ diameter dumptube. This is hardly adequate for proper flow and causes the wastegate to perform insufficiently. The 3d machined transition in our flange allows the wategate gas to flow smoothly into a large 2″ diameter dumptube and allows the wastegate to work properly. Also please review the test results from Prototype #1, http://forums.evolutionm.net/vendor-announcements/433677-shearer-manifolds-02-dump-released.html.
Price is $442.14.
