Because this 1jz will be going into a S14, we removed the clutch and fan assembly, as we cannot use it due to space restrictions.

We will be running an aftermarket BOV, so the OEM VSV, associated wiring and lines can be removed.

Bypass valve VSV

Gone, we will use the stock vacuum port for the aftermarket BOV.

The OEM Turbo elbow is extremely restrictive, it will also be replaced with a Future Fab Downpipe

The exhaust side engine bracket can be removed since we will be using SG Conversion Brackets

On the intake side there are two VSV's, fuel dampener, stock engine mount bracket that can all be removed

 

Water lines to throttle body, you can also see the OEM power steering line and vacuum source. All of which will be removed.

Water port for the TB that is no longer necessary

 

The water port for the TB, hose removed, it must be blocked off

Water to IACV, also removed

Fuel dampener can also be removed.  The conversion mounts will bolt on to the two holes where the dampener was originally mounted.

Hard water pipe to water to oil cooler is visible after clearing out the VSV, lines and junk.

 

With the intake manifold removed you can see the lines, pedestal for the stock water to oil cooler.  All of which will be removed.

With the pedestal gone, there is no provision for the oil filter, we installed an Oil Cooler Delete Stud

OEM Water bypass hard pipe from water pump

The original pipe was modified to keep the correct flow of water. We will be running a heater core. The water outlet from the rear intake side of head will be routed to the heater core using a heater core conversion hose

We were not going to retain AC either, so we removed the compressor along with the stud left over from removing it.
