HEAD S4, oversized valves, full race port, shimless buckets Stage 4

The Titan Motorsports Stage 4 Cylinder Head sits perfectly between our Race and Street cylinder heads. It is highly suggested to run a built or prepped short block for this head package. This is the same cylinder head that was developed in the famous Titan Motorsports Pro Street Tire Supra and pushed it into the 7's in the ¼ mile to be the fastest street Supra at the time. Since then, this head has even been used on pro chassis cars to run low 6's.



Specifications:

• Cylinder Head: GTE-Standard Headstud -NEW CORE
• SuperTech Buckets: No
• Camshafts: No

We start by cleaning and pressure checking the core cylinder head, then remove the valve guides and do a full CNC port and polish, including CNC'ing the combustion chambers. We plug the additional water passages that are not needed for a performance head. The valve job is done on a Newen Contour machine that creates the optimal valve seal machining and angle. Then full re-assembly is done with Ferrea Guides, Ferrea Dual springs, Titanium retainers, seals, locks, +1mm valves, and Titan Motorsports Copper Seats.

As an option, we can install Supertech shim-under buckets and Supertech shims. These buckets must be installed for the specific cam that you have, cams must be supplied or purchased and will be set and shimmed for each specific head. This allows you to safely rev above 9,000rpm if you so desire. The buckets are half the weight of the stock bucket and prevent the common shim spitting that can occur with high revving engines. These are the same exact buckets and shims we use in our pro car race engine program that has gone deep into the 5 second quarter mile times, as well as 3,000+ HP.

Additionally, we offer ½" Head Stud Machining for those wanting extra head to block clamping. This pairs well with our Titan Motorsports ½" Head Gasket TMS SUP-ENG-420 and Titan Motorsports ½" L19 Head Studs TMS SUP-ENG-418 (Both Sold Separately.)

We offer our Stage 4 Cylinder Heads to be built on brand new OEM Toyota Cylinder heads for an additional cost, or we can reuse your usable core. Both Available in GTE or GE and VVT-i and non-VVT-i.

The extra attention to detail and custom manufacture of hardcore specific parts makes the Titan Motorsports head package above and beyond other heads that use plain off the shelf parts. If you are looking for serious performance, you found it.

If you choose to purchase the cylinder head with 1/2" studs, we recommend these optional bundles for your build:
