Part # PHR 01011093.CSI

 

Old tech made new -- Distributor Delete and Coil Over Plug Ignition

By providing a simple location to mount a cam sensor in the 2JZ-GE Valve Cover, these valve covers were designed with the purpose to be able to convert the 2JZ-GE non-VVT-i cylinder head into a more modern version. It serves multiple purposes:

  • Provide a location for a cam sensor
  • Delete the distributor
  • Convert the ignition to Coil over Plug
  • Provide the MAXIMUM breathing capability
  • Look amazing
  • Extreme Light Weight

Features and solutions

Light Weight

Powerhouse Racing Billet Valve Covers are precision machined from solid 6061 billet and retain OEM fitment. Weight comes in at only 5 lbs. 14 oz. compared to the stock valve covers at 7 lbs. 9 oz.

Maximum Breathing

Designed for race cars, the rear ports are LARGE for maximum breathing. Multiple breather options are available for standard breather tanks to dry sump engines running pop-off valves, vacuum regulators and crankcase pressure sensors. For those needing an oil cap, one of the rear ports can be used for an oil cap while the second port is large enough to allow for lots of air to still vent to a catch can.

Additional -12ORB Ports: We've also incorporated two additional -12 orb ports near the front of these valve covers. We did this to even further enhance the breathing capability of these covers by providing locations for lines to PHR/Dailey Engineering Vacuum Pump Kit. But this also allows for even more breather setup possibilities.

Valve Cover Options

These valve covers sport a single -20 ORB opening on each one. You are able to select your options for fittings. -12AN, -16 AN, -20 AN, -20 ORB oil cap, or -20 ORB plug each sold separately.

Pressure Sensor Port

We have provided 1/8 NPT ports on both the intake side and the exhaust side. This gives two options for use of a crank case pressure sensor. We've found crank case pressure to be a vital data point for helping determine the effectiveness of the breathing system or drysump system. It is also helping to keep an eye on the healthiness of the motor.

Features

  • Removable baffles for easy cleaning
  • Rear sensor port for measuring crank case pressure
  • O-ring cord seal
  • Only 5 lbs. 14 oz. combined weight
  • Works on 2JZ-GE Non VVT-i engines. 2JZ-GE engines must use front facing intake manifold.
  • Pressure sensor ports on both intake and exhaust. Useful for a crank case pressure sensor.

Sealing with common cord stock

They use O-ring cord stock for sealing, all the way around the cover, including over the front cam cap with very precise tolerances. This allows race teams to carry some cord stock in their trailers to replace is the valve covers ever need to come off with very minimal expense over the factory valve cover gaskets. 

The cord stock is fully compressed into the valve cover allowing the valve cover to come into full contact with the mating surface to act as a further heat sink as well as making a solid precise mount of the valve cover. A dab of gasket maker or "FIPG" is all that is needed in the corners of the front main cap to get a great seal and that very small amount of sealant makes cleanup simple.

 

Intake cam sensor

The intake cam sensor is utilized when converting a 2JZ-GE with a distributor to coil over plug.  

This will require that you use camshafts for the 2JZ-GTE​.


You can source OEM or aftermarket cams, but the intake cam must have a pickup / tooth for the cam sensor to read.

The Rigid Ultralight covers utilize dowels that perfectly align the valve cover to the 2JZ cylinder head using existing machining in the factory 2JZ head. This allows certainty that the intake cam sensor will be located in a perfect and repeatable position. Further, by using an o-ring cord, the valve covers are "rigidly" mounted, meaning the cam sensor stays firmly in position.

Obviously, this will require an aftermarket ECU as there is only one sensor, as well as it's position being in a different rotational position than the stock 2JZ-GTE.


Crankshaft Position Sensor Requirement

The second part of the equation to converting to coil over plug, is the crankshaft position sensor. You cannot simply run these valve covers. You will also need a crankshaft position sensor. Some vehicles with distributors will already have this sensor (see the 1997 Toyota Supra non-turbo). But most will not have it. You must have an oil pump and timing belt drive gear to accommodate the crankshaft position sensor. These are not easily installed. Changing the oil pump requires removing the oil pan, which would also require removal of the engine from the vehicle, or lowering the subframe.


As part of a complete build, this is not a big deal. You will be replacing the oil pump anyway. So in that case it just requires installing the correct pieces. Here are those pieces with links to each product:

Oil Pump or Front Cover

All of these have provisions to mount the crankshaft position sensor

Timing Belt Drive Gear

These have the trigger teeth for the camshaft position sensor
