TunePlus, Inc Built Blocks and Upgraded Cylinder Head Information


If you have ANY questions please email We want to insure there is no confusion on what you are getting, or what is all required by you, the customer, when you receive your TunePlus, Inc Shortblock or Cylinder Head.



TunePlus, Inc Type-A Shortblock (<500whp)
Designed as a drop in replacement for customers that had an engine failure and just looking to get back up and running with something better than stock, or for someone not looking to make over 500whp. This engine uses our standard length rods, and our standard duty pistons. Focus ST customers, please note this engine comes with a 94mm stroke crank so it will be a 2.3L "stroker" for your vehicle. 

Compression Ratio - 9.8:1
Displacement - 2.3L

TunePlus, Inc Type-Z Shortblock (<600whp)
Designed for customers looking to drag race or track (road course) their car. Our Type-Z Engine features a 2.0L (83mm stroke) crank, our "long rod" connecting rods, and our custom designed pistons featuring a more robust crown and dish design for better fuel distribution with port injection. Pistons are also coated with the Gold piston coating to for detonation reduction. The 2.0L displacement  was chosen for reduced piston sideload/friction, reduced cylinder head stress from lowered dwell time, and a better overall rod ratio. Though you will experience a hair lower spool and response (<500rpms depending on the turbo being used), you will hardly notice in daily driving. What is more important is that you have increased your engine's ability to handle the stress in higher power levels. It's no secret that Ecoboost engines have headgasket issues from extremely high cylinder pressure, and turbine pressure. Turbine pressure can only be reduced so much due to the restrictive head design, but if we can reduce cylinder pressure we effectively reduced turbine pressure and the possibility of lifting the head.

TunePlus, Inc Type-A Cylinder Head
Designed to be paired with our Type-A Shortblock. This head is assembled with the components listed below and features stock porting. It's purpose is to get a customer a brand new cylinder head ready to installed, with a noticeable increase in top end power over stock, at a low cost. This cylinder head will provide stock like drivability and no change in engine vibration at idle.

TunePlus, Inc Type-Z Cylinder Head
This cylinder head was designed to pair with our Type-Z Block. It is the only cylinder head on the market to incorporate and O-ringed deck. O-ringing is a process where a profile cut is made into the deck surface to house copper or steel O-ring material. The O-ring sits slightly above the deck surface and crushes the gasket around the cylinder. This reduces the chances of a headgasket failure by increasing the sealing pressure area around the cylinder SIGNIFICANTLY. It also features our new camshaft profile for better drivability and idle quality, without the sacrifice of power. Our camshaft specs will not be shared publicly at this time. There is a slight increase in idle vibration from the camshafts, equal to installing a set of upgraded engine mounts.

Unlike our Type-A cylinder head option, the Type-Z does feature porting. Intake side porting has provided an average 32% increase in flow across all cylinders, while still retaining the factory "DI wall" for optimal fuel distribution in the cylinder. Exhaust side porting has an average 26% increase on the on the outer cylinders, and 6% increase on the inner cylinders to get flow on the exhaust side as balanced as possible for equal cylinder power production. Because of the cylinder head design the center ports flow significantly more in stock form, so the outer ports have more aggressive port work done on them to try and "catch up" to the center ports. 

RS / Mustang Stock Airflow Numbers:
Intake: 157cfm @ 28"
Exhaust Outer: 127cfm @ 28"
Exhaust Inner: 147cfm @ 28"

TunePlus, Inc Airflow Numbers:

What do you get?

You get a completely assembled shortblock or cylinder head. You will be required to move over your factory components like Timing Cover, Oil Pan, Valve Cover, Sensors, and other Hardware. All your factory components will bolt on, nothing is changed on our engines to affect fitment of any of these components, any turbo kit, and any intake manifold. It is recommended that you replace your oil pump, oil pump pickup, and timing components with NEW OEM parts during assembly. We can supply any new OEM parts you need, please just email

Assembly: If you have any questions about the assembly of a shortblock into a complete engine please email Below is a PDF document of the Ford Factory Assembly process which can be followed 95%, the only difference will be if you are using ARP headstuds then you will use the ARP instructions for torquing the head. 

Ford Factory Assembly Manual (Start at step 32) - Click Here

  • It is recommended to cover the rear aluminum oil galley plug with High Temp Epoxy and let it cure for 48 hours before installing and running in a vehicle. This will guarantee no oil will leak from this plug.  
  • Before installing the headgasket and head studs clean the deck surface of both your block and head with acetone or brake cleaner to remove any assembly oil and debris
  • Ford OEM Rear main should be installed with extra care, or they can leak fairly easy. Make sure the crankshaft is 100% clear of debris and oil, install new rear main seal with the provided tool in the rear main seal package from Ford. Torque bolts.
  • When installing the oil pan make sure you have a lot of Ford TA-29 Sealant on the oil pan and the rear main seal mating surfaces. The surface area on the corners is very small and can be a source of leaks.

Break In: 

Mustang - You must have UPR Catch Can installed with the PCV Valve gutted, and 100psi UPR Checkvalve installed on the intake manifold line. 

Focus RS/ST - You must have a Radium PCV Catch Can installed with the PCV Valve gutted, and 100psi UPR Checkvalve installed on the intake manifold line. 

Radium Baffle plate can be used in place of the factory PCV Baffle Plate, just make sure if you get any low engine speed smoking you want to gut the PCV valve and add a the checkvalve as outlined above. 

We recommend that all customers use Amsoil Break-In Oil (available on our store) for initial start up and break in. Vehicle should be started and checked for leaks, then a Misfire Monitor Neutral Profile Correction procedure done. This needs to be done with a high end scan tool or taken to a dealership. This needs to happen first then you immediately start the break in process.

You want to get into steady/constant boost (15psi or less) within the first 20 minutes of the vehicle being started and driven so the rings seat properly. Never keep a steady RPM or Speed during break in. ALWAYS KEEP THE RPM MOVING! After 20-30 minutes of varying RPM/Speed and Boost, drive the car for 50 miles before changing the break in oil to your normal running oil (3,500 intervals, 7 quarts because of balance shaft delete). We have Liqui Moly oil change kits available on our store.

Begin the tuning process immediately!
