Isuzu G-series Twin Cam

in posts just above it was stated that LRP (lead replacement petrol, actual leaded petrol hasn't been available for a few years) is being phased out, I cannot get it anywhere near my place at all, only ULP or PULP.

Poida, while I do agree with the whole replacing them if you can, and also about working an engine hard will shorten its life... but keep in mind when gem says that he has never had problems with it, that means something... his twincam(s) are race engines, that constitutes working an engine harder.....

all this talk about spending a lot on setting up an 808 so it can be reprogrammed etc... have you ever read into the megasquirt poida, specifically megasquirt-n-spark ? While it will technically be illegal because it can be tuned in real time, its usually in a boring stock looking case that should g...

also, the fuel injector rail, or fuel rail as it is normally called, is the tube that feeds fuel into the injectors...

The part that is bolted onto your block that houses the injectors is the inlet manifold... You are looking for the plenum and throttle body basically. You can get a custom plenum made, might be exy though, and you can use a throttle body of most EFI cars at a wreckers... people seem to have had succ...

if you meant AIC as IAC below, as in the little device that lets air straight into your manifold/plenum after the throttle plate, and said you might have problems with stalling coming off throttle, then by my understand (and I could easily be wrong) you are mistaken. IAC's are for cold engine start ...

all good points Poida... As for the lead petrol issue with the LRP and restrictors.... I can't even get LRP around my place, its only ULP or PULP at the servos and has been for a while. When I get a bit closer to finishing the project I'll talk to my engineer and see what he says, if I need a restri...

G'day, I know this may change state to state... but in fitting a dohc to my TE, do I have to fit a catalytic converter? From what I remember, if the car the engine came from had a cat, then you have to... so, I think my engine came out of a ZZ/Z or ZZ/R or ZZ/T (did they all have dohc's?), did they ...

I was hoping you'd do something... was thinking you'd be crazy to drive it without even socking it! hehe They would sound awesome under full throttle, wish I lived nearby. Haven't chased anything up about rings, won't until I at least get the engine running and see how I go. All I have to get for th...

those trumpets look so sexy

do you sock them?

if only.... no, its just head gasket up

I had my cam one tooth out on a G200Z once... it didn't even start... not too sure what might be the deal with the twincam

I knew I was forgetting something V2032KC Thats for the G200W, they dont make them for the G180W or the G161W, the gaskets are all exactly the same between the engines (at least with the G180W and G200W) just the bores on the head gasket are a couple of mm bigger for the 200 as opposed to the 180 of...

You can get VRS kits from Burson automotive, who have stores all over australia. The kit costs about $170 (or $100 if you get lucky and they undercharge you :wink:) It includes a good quality graphite/carbon fiber head gasket intake manifold gasket exhaust gasket cork rocker cover gasket and it even...

Thought others might find the injector specifications usefull.

I have a G180W and my injectors are stamped with A46-000001, if yours are too, these are the specifications

manufacturer: JECS
impendance: 2.4ohms
flow: 196cc at 3bar

forgot to mention that the previous owner sold me the engine set up with a crane ignition system, but forgot to give me the crane ignition module. So I had a fixed dissy (no advance or retard) with an optical sensor in it and no way to drive the ignition. This was most of the reason I got a megasqui...

the standard dohc cams look aggressive... they have 400thou lift... race cams usually have around 490thou lift, and of course a different profile

I third the Delco 808, however I went the megasquirt(extra) because its cheap, it does everything all the expensive ECU's do and it is easily retunable. I also got it because I needed a fuel+spark computer as I had to do away with the distributor. There is quite a bit to setting up a megasquirt thou...

Here is a photo on how to time your cams, as posted in the technical details forum. http://img508.imageshack.us/img508/5570/g200wtiming3ec.jpg Here is some photo of a twincam and basic info http://img516.imageshack.us/img516/2402/g180wonly9nb.jpg another photo http://img516.imageshack.us/img516/3574...

Here is an image that will explain how to time the cams for a twincam... I took my cams out and then, stupidly, realised there were no markings on them to say where they were meant to be, and since it has adjustable cam sprokets I couldn't line it up using the dowel pin as I didn't have one! http://...

Poida and others, Good idea mate, I was just thinking the other day that a twincam forum would be a good idea. First off, I think I'll just introduce my engine and where it's at... I bought the engine quite a while ago to put into my project shell I had. I live in Brisbane and I bought it off a blok...

G'day,
I found this japanese site a while ago that has some basic G200W info, as well as a couple of other isuzu engines. Have a looksee, if it asks you to install japanese language packs, just click cancel
