Isuzu G-series Twin Cam

That link shows what sort of mentality exists on that forum. Parallel impedances indeed! No wonder wiring up an alternator is too difficult for some. Geez! But lo-Z injectors is not a bandaid solution! The Delco handles lo-Z injectors and it was designed that way. Otherwise they would have used lowe...

Provided you have all the bits off the Piazza (ie, sensors, TPS, etc) and it's a reluctor dizzy, it should run. The G200W dizzy reluctor should be capable of driving the ECU. (I can't recall if the RG breaker plate is the same dimension as the G-W. If so, it might be swappable if the lobes are compa...

Poida - I thought the Isuzu (low impedance - of course!) injectors were Delco compatible - provided the ballasts/resistors are added. As I understood it, the Delco could power both low-Z & hi-Z, the only proviso being the current limiting for the low-Z (ie, add the resistors). (If any ECU can t...

For wiring, I suggest isuzupiazza.com/index and get the 1986 Piazza Workshop Manuals (900 Pages for 4ZC1 Turbo Model) pdf. However that is for the 4ZC1-t and not the G200W Piazza (which uses an I-TEC system with a locked optical dizzy similar to 4ZE1 Jackaroos & Rodeos). You need to get the ECU ...

That's my recollection - all "block cam" bearings (and big ends & mains) are the same for ALL G-series engines. But the OHC shells are or may be different. There might be (block/dummy) cam groove or hole differences. And some engines had 5 cam shells (GT Bellett G161U) instead of the n...

Oh dear, it's one of those Netters... They're still learning last millennium stuff! If referring to the OHV cam shells, they are the same on all G-U (OHV), G-S (Jap SOHC) and G-W (DOHC) engines. (G150U, G160U, G161U&S&W, G180S&W, G200W) I can't remember the details of the G161S & G18...

It's listed on the Isuzu Owners Club (Finland) as a "bearing; cam shaft" (STD) for an OHV engine.
That means the OHV cam = the DOHC dummy cam bearings.

The first digit 9 means it's a Bellett number. 8 is Gemini & Piazza; I think 5 is Florian etc (hence maybe LUV & KB)

He's still alive...
But due to other crises, it seems scarce.

The compression etc should be more than adequate. It may simply be an injector problem. Poida fitted a Delco to his Gemini (blue) G180W. I think yours was a green G180W, but that shouldn't matter. Though Delcos are commonly taken from the JE Camira (the last model Camira from 1987 which finally over...

Awaking and old/dead thread, but updating the DOHC distributor situation. Keep the DOHC/G-W dizzy gear (at the bottom of the dizzy shaft) and use an electronic Gemini dizzy - eg, a RWD T-series Gemini or any G-Z engine dizzy with FWD RB-Gemini dizzy guts. This is known as the "RG" dizzy an...

Thanks.
Now I have to reboot my memory banks! (Were Elky's from that batch???)
I know the original batch remakes had tapered ports which apparently is unusual...

BTW - those Elky had IMO are friggin' good!
As to others I've seen...

When you say replicas, you mean the ones similar to, but not the batch of ~45 (pairs) that were made in the 1990s?

Thanks! And that's the first time I have heard a price. Be aware that Poida is negotiating price (and other things) for us twincammers - ie, see Re: G200W Full Gasket Set . (For a related recent thread, see g200W VRS (Vale Regrind Set?) incl. head gasket .) IMHO $305 is a good price - especially whe...

I finally met up with my Guru after many years... He confirmed that there are no issues with the GW oil feed - certainly unless talking about 500bHP etc - though we did discount the G161W (as a piece of shit, but that is a relative statement!) As to oil going through the dummy cam or even removing t...

Nothing to be sorry about - I'd rather repeat or even wrong info that could become something... I didn't even recognise the company until I found that other thread. Then reading my own comment that the cam-valley or timing chain cover to head rubber gasket was included stirred up greater interest. (...

Once upon a time, instead of us multiply & separately buying, we went through someone that acted as a single buyer. The bulk purchase not only made things cheaper, but with only one buyer, the sellers had little leverage for high prices. The Bellett club (BCCV) did similar things in their earlie...

LOL!

That lead wasn't from G200W Full Gasket Set per chance?

Invaluable info - thanks! I was thinking of hitting the beach tomorrow. If so, I might drop in. (For a look only, being FUCKed (Financially Unable To Conceive Kids) also extends to my G-W children.) They mention KP Gaskets, but also MDS as well as OEM parts. Of course I'll see what else they have - ...

Good old AA eh? Founded thanks to the BCCV (or largely so). Dumped $3,000 worth of Bellett gaskets some years back... (I was about to buy for under $1500, but then Management gave the founder the boot. :evil: ) But what is it with Isuzu gaskets? Permaseal list the V2032 series as being for the G200 ...

I should have G180S brackets, but that's the same block as G200W, and it may be the front type of bracket.

I should also have G200W center brackets...

(Funny how forums are quicker than email (replies)... )

Go Delco. I am.
Why?
'Cos I bluddy sold my manifolds! (And now that Webers are half oldskool prices...)


Sorry - we both seem to be involved in topics that died.
Let's see what this resurrects.


BTW - which engine do you have?


PS - should contact elky if he doesn't reply...

Upon rereading Poida's answer, I wanted to emphasize his point: Emissions components are not really as simple as adding something off another similar engine. Don't even think of bolting others on. I suspect that if " few other engines breath like it " wrt fuel, then certain things like air...

What brass sleeve? Just use shim (0.15") or even epoxy - it's only 0.20mm slack (a 0.40mm diameter difference). But a sleeve is probably cheaper than those that buy a NEW Magna dizzy and pay $300 for a cut&shut - all for a non-CAS requiring Delco or uTech etc. I'd rather spend that ~$700 on...

Most other states are the other way around - the engine must meed the ADR for the vehicle - ie, a '79 G200W in a '86 Piazza must meet '86 Piazza requirements.
That's why I like my pre-ADR (1974) vehicles.

Thanks... I vaguely remember that site. They appear very close to the "GTR-replicas" that were cast a decade or 2 back. I was searching for some pics (I'm certain Elky & I posted some comparisons) but failed. AFAIK they are still regarded as the best manifold - short & tapered. I g...
