Isuzu G-series Twin Cam

The "Z" oil pump is a gear type driven from the crank at the front of the motor and hangs down into the sump, mounted under the front cover. The "W" oil pump is a 'tri-chord' rotor that mounts into a different place on the outside of the motor. The only known part the same for th...

Been "off-line" for a while setting up my business - 18hr days don't leave much time for anything else. I have dumped three Piazzas just to clear the decks and make room for work that pays. Sold one G200W motor to a farmer who wantd to make a compressor out of it - kept the ignitor. Still ...

I shall pack and weigh one - Best Lady has just returned home from hospital after having eye surgery - cataract removed so I have a coupe of busy days ahead of me till she can see again. Will do ASAP but it may be the weekend before anything happens.

Sorry about not logging in - sometimes things on the computers elude me and I run out of time to find out what I did wrong! Rang an Auto Dismantler today (GM specialist) and asked about a G200W Ignitor: "$NZ150 - have only one left" If that sounds too much just let me know your best offer ...

The "Fidanza" alloy flywheels are for sale BTW. They have a hardened steel (replacable!) insert on the clutch friction surface, a ring gear fitted and come with new clutch cover bolts. My Piazzas are autos and I have abandoned ideas of converting to manual gearbox - can't find any good one...

yeah am short on that stuff !!! try a sohc one, the bolt spacing is right but i haven't tried to fit one yet I have a couple of G200Z (SOHC) "Fidanza" alloy flywheels and have tried them on the G200W (DOHC) crankshaft and they fit exactly. Now I can upload pics - here is the proof. DOHC f...

Went for $860! Can't even get that much for a WHOLE 2.0 G200W Piazza car here - more like junk here I guess.......

Still trying to upload a pic - click the wrong thing and it all disapears. Five attempts so far and hours down the drain! Need a STEP by STEP instruction somewhere - I read the FAQ and it told me about the CTRL C bit but Ihad to ask the neighbour about the CTRL V bit to "paste" it. Then th...

Thanks Poida - with luck here is a pic of the G200W "dissy":

Just get message: "The page cannot be displayed"

OR the whole page "freezes" when it shows up with the only thing that will"click" being the "Post to Blog" box

They are complete units that look just like distibutors. Never seen a G180W - only ever seen one Gemini over here - driving past so I have no idea what a Gemini one looks like. I will be at my workshop tomorrow trying to find some Opel parts a local wants. Will try to load up some pics this week end...

I have three complete G200W (DOHC) "ignitors" I guess you can call them distributors ... they stickout of the cam cover at right angles to the motor and have a distibutor cap and leads on them. Also have complete twin cam motors - several of them out of early 1980's Piazzas. PM or e-Mail m...

I have several Isuzu Piazza G200W (DOHC) ones - are they the same??

The DOHC cylinder head is either a Lotus design ... or a good copy of a Lotus Cortina one. Differences in head bolt spacing and other dimensions but the basic layout and design are too similar to be co-incidental. Besides which GM was suposed to "own" Lotus in the time frame of the head's ...
