Bolt Torque Information

The bolts tension specs used in the twincam engines are generally the same as the ones used for the SOHC engine. However, there may be some exceptions. I have listed the SOHC G161Z and G180Z specs from genuine Isuzu engine manuals, also an image showing bolt diameters, thread pitch and metal the bol...

Re: Avast! blocking twincam...

Not sure why your AV is doing that Pete... Not being familiar with your AV software I can't make suggestions on how to remove the block. Perhaps contact their help service and see if they have an answer.

Re: G161W-G180W-G200W bearing sets (including cam bearings)

Time to resurrect this thread again, another run of these FM cam bearings has been sourced. Anyone wishing to purchase sets of cam bearings (for the two true cams) please make a note in this thread. The dummy camshaft that is located in the block uses a different set of bearings which we also think ...

Re: g200w turbocharged?

G180W and G200W twincams are going to be quite difficult to find. This info is only about The SOHC engines, not DOHC engines . Turbocharging a GZ engine can be done... better value than the twin DCOE setup. US market G180Z and G200Z are similar to the ones we have here in Australia. Iron block, allo...

Pete, ITB are a huge step up in fuel/air delivery. Like going from a simple single carb to feed four cylinders to two DCOE/IDA feeding a cylinder per barrel.

Re: ITB's

Have to admit, if I were ever going to (further) upgrade a twincam engine that kit (or one similar) is probably the ideal starting point. For now I'm keen to see just how much benefit and extra I can get from the Delco upgrade I have done. It has to improve over the 'hard wired' ignition curve and p...

Re: Oil cooler ?

Without having a pump in front of me to investigate more thoroughly, I'd say the spring loaded ball would most likely be a pressure relief vent to limit maximum oil pressure preventing over pressurising the system. Any line designed to serve as an oil cooler supply would need some sort of restrictio...

We (IZU069 & myself) have been discussing options for the right injectors. I have found that the low impedance original injectors will run but they don't run well straight 'out of the box' using the current DelcoHacking tune data for the G200W. I think it would be logical to swap to the same inj...

Re: G161W-G180W-G200W bearing sets (including cam bearings)

Reason is the twin cam g series was never an engine released in Australia and parts supply are limited. Cam bearings are one of a number of parts not available here. The C172L bearings are simply not available in Australia. The Federal Mogul bearings shown in the photos have been imported. They were...
