Isuzu G-series Twin Cam

The TPS from the Commodore TB is the one to run, I think each TB has different locating notches to suit in the TPS. Same with the IAC valve, the Astra one is slightly different (the angle the wiring plug fits in). As far as I can figure, the components are the same electrically, just physical variat...

IZU069... a mention of injector choice from another source: http://www.delcohacking.net/forums/viewtopic.php?f=7&t=833&p=9810&hilit=low+impedence&sid=168f2b86b2ad8497dc2c5813ad23dbd1#p9810 I got the impression it would be better to source a set of high impedance injectors that fit ra...

I have most of an EFI setup from a G180W Gemini engine. I have the loom, the computer, the throttle body with the TPS and a few other sensors that were part of the original EFI system if you are keen. The AFM was stuffed and not repairable. Personally I'd do what IZU069 has suggested and convert to ...

Extract showing G series Isuzu engines from Taiho engine bearing listing

Hi people, I have updated to a new forum look, I think it's cleaner looking and suits a car forum. The original template has an image in the grey header bar but I've removed it pending a new image being developed. This is how it looked in default mode: forumheader.jpg and this is a full size of the ...

All the OHV cams were in block type resting on three full circle pressed in bearings weren't they Pete? One size fits all?? I have seen listings for OHC bearing shells, so is it that the G161S & G180S both had removable bearings for the cam? Have a look through this listing Pete http://www.taiho...

I have explored all the different locally produced 4 cylinder EFI sub looms for their suitability as a conversion source for a G180W/G200W and have found the 1.8 litre MPI LD Astra/ N13 Pulsar to be the best option requiring least rerouting or modification of loom components and provides ample loom ...

I have looked closer at my G180W injectors and after researching it seems quite a few JECS injectors have the number A46-000001 on the body opposite the 'Made in Japan' marking. I did note that these are both 'cast in' raised markings which often only describe the reference to a base part number and...

I have before me two boxes of bearing half shells which seem to be the ones we have been looking for. http://imageshack.us/a/img849/3983/20120802214803663.jpg They are Federal Mogul bearings and I'm yet to do a final check against the bearings in my engine. I'm assuming both the base and cap shells ...

Keeping in mind mine is a blue top Gemini G180W, I found the engine wiring loom from the LD Astra/N13 Pulsar 1.8 litre MPI setups (they are the same setup rebadged) was more useful. The wiring in the engine bay is nearly identical to the 2.0 litre MPI JE Camira but the length of wiring from the bay ...

Today I added some fun user rank icons.

A big thanks to Cian Walsh for the free icons.

Ok, all chit chat aside, I really could use a pair of these engine mount brackets... Must be to suit the G180W Gemini engine.

I'll buy them if for sale, borrow them if need to copy and fabricate a new set.

Someone has to have a set sitting idle on a spare/parts engine???

We'll have to set the infamous IZU069 onto them then!!!


We need to keep a tab on what goes on in this small world of twincams. It's too easy to lose good connections then lose a supply link.

I have been in touch with the owner of MD Spares and explained our situation regarding the need to source parts for G series twin cam engines... help is on the way!! :mrgreen: They have a number of parts available including the above mentioned G200W FULL gasket kit (G295SC) so the sump gasket proble...

I've also found AA Gaskets stock G200W gaskets.
No listing for the G180W gaskets though

G200W
Valve Regrind Set - V2032KC
Head Gasket - S2032KC
Rocker Cover - RC3000
Manifold Inlet - MG3000
Manifold Exhaust - MG3001

Hmmm, looks like I'll be down for another weekend visit soon huh! :mrgreen: I want to ditch the modified petrol cross member and fit a diesel one. Does anyone with a genuine G180W engine bracket set, in the right places (not swapped about) feel like snapping images of the brackets on the engine for ...

Anyone got a spare set of genuine G180W engine mount brackets??

A little while ago two complete sets and a half set of actual twin cam bearings were located. We now have another part number to reference and we are trying to locate more sets of these bearings. They don't come as a set of 20 half shells, there are in sets of 10 so two sets are needed. Will keep ev...

Does anyone have a part number for the oil seal behind the front crankshaft pulley? Doesn't have to be genuine Isuzu number... If someone has a full gasket kit laying around the seal would be in it, check for a brand and number on it (or the package it's in)

Emissions components are not really as simple as adding something off another similar engine. Just because a locally produced DIFFERENT engine has an EGR system doesn't mean the twincam has to have one as well. You could just as easily argue that modifying the Japanese system (Japanese had a stricte...

Don't be mistaken, advantages of using Delco are it's robust, cheap, able to do all you'll need. I use free software from TunerPro and low cost hardware from Moates APU1 AutoProm Package . antus can also show you a locally sourced method of reprogramming the Delco using similar means. More details a...

No reply to my email I sent them so I'll resend another email. We have to eventually break this cam bearing drought!!

It was a test Pete, I know it's not you now!! No way you can post one liners!

It's one of the anti spammer tools. Might even bump it up to prevent posting links and nothing else.

I would much prefer to find some already made. At least we now have some part numbers to work with. I have found original Isuzu part numbers for them as well as these Chinese bearing company number. The part numbers I have are: C513B [3] (SH-1032B) (C171L) 5-11611-002 9-11611-020 C514B [10] (SH-1620...

I have emailed the company who responded and asked what quantity they require to develop the cam bearings for us.

Meanwhile I am still looking for other suppliers.
