ported VVT race head, 254cfm, freshly rebuilt, $1500
Email me at info@trackspeedengineering.com to inquire. I do not use the PM system on this forum
This is the race head I had built for Rover's national 2013 PTE engine program. It flowed 254cfm intake at 0.370 lift on my builder's flow bench and made 138-142wtq on 91-octane gas (depending on which Dynojet you believe). It has a full intake/exhaust port and full chamber deshroud all the way to 85.5mm. The builder's instructions were to "get the best flow possible, combined with the smallest port possible, cost no object".
In addition to the portwork, it has:
Supertech stainless +1mm valves intake/exhaust
Supertech heavy double valve springs w/ titanium retainers
Supertech solid lifters w/ 5.5mm lash caps
Low-hour SI bronze valve guides (guides were done when the head was ported in early 2013)
Stock VVT cams
At the NASA nats in 2013, the motor broke a VVT oil line and suffered a rod failure which damaged the head. The subsequent damage to cyl#4 is pictured below. The sharp edges have been knocked down and the builder has given this head his blessing in its current form so the damage should not cause issues, but it is worthy of disclosing.
The head was completely torn down, hot-tanked, and rebuilt after the rod failure. It is shimmed and ready to install as-is, with one exception: the new owner should pre-emptively change the intake valves, as these are failure-prone Supertechs. I will ship the new owner a brand new set of Manley SS +1mm intake valves along with the head.
$1500 shipped. Open to reasonable offers as well. I hung onto this intending to build either another 2-liter N/A BP or a monster VVT longblock at some point, but I've decided to stick with the simple, low-boost EFR setup that's served me so well the last 3 years.
