Alternator Relocation on JZ oil pump with locking idler pulley
JZ oil pumps with locking idler pulley have a casting for the OEM dampener that interferes with the bracket install. It is a non-essential nub that can be cut off without adverse effects to the pump.
Bracket fits flush
VVTi 1JZGTE Swap Prep
Stock JZX100 1jz auto set
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.
Clutch and Fan Assembly
We will be running an aftermarket BOV, so the OEM VSV, associated wiring and lines can be removed.
Gone, we will use the stock vacuum port for the aftermarket BOV.
VSV and associated lines
The OEM Turbo elbow is extremely restrictive, it will also be replaced with a Future Fab Downpipe
You can inspect the turbo while the stock elbow is off
The OEM Ecu will be retained so the OEM O2 sensor will be reused on the new downpipe
The exhaust side engine bracket can be removed since we will be using SG Conversion Brackets
Future Fab Downpipe installed
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
Port can be welded, but we have opted to pull the fitting (it a pressed-in steel tube in an aluminium head, a little heat and vice grips pulls it right out) and tap to 3/8 NPT.
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.
Intake side with all unnecessary lines removed
Oil cooler and pedestal, stock engine bracket
The return port from the OEM Oil cooler is 3/8 BSPT from the factory, in order to put an 3/8 NPT plug, you must run a 3/8 NPT tap through the port.
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.
AC Stud left from removing the AC compressor
AC compressor removed along with the stud that's in the block.
AC compressor with hardware
We will be installing a no AC serpentine belt
Another view of the side with intake partially removed
Top cover and upper intake manifold removed so the stock harness can be removed
Stock engine harness removed so it can be converted.
At this time we also removed the coil packs for inspection and replacement of spark plugs.
