Isuzu G-series Twin Cam

Up here in QLD you cant put an older motor into a later model car, but as long as it was in a JDM Gemini at the same time my GMH TF was built Im cheering. They have no idea about the engine, we struggle to know the finer details at times and we love the bloody things lol so that may work in my favou...

Yeah its a runner, though got defected so aint going nowhere atm I need to get a mod plate for the twin cam conversion, which is no big issue, engineer is happy with the install just need a charcoal canister fitted. I agree with the benefits of the RG dizzy conversion, one Im going to do, the sandwi...

I told the engineer it was 1982, same as my TF :P and on that he said all I needed was to use the Gem emissions system. Id have to imagine that anything from an Australian TE to TG should have the same emission requirements for the mod plate, they all use the same emission system standard I believe

$140, which I was happy with after the headaches it caused me...though its work I could have done myself had I found the problem.

Im going to go the RG dizzy, Im collecting the bits now as Ive had soooo many dramas with the original dizzys

Can anyone tell me what year the G180W first made its appearance in a Gemini? I need to get a mod plate for the twin cam in my car and engineer needs to know what year it was released in a Japanese Gemini, it seems at this stage all I need for the mod plate is to have the original Holden EGR valve s...

They are made by Daido in Japan, they pretty much have 100% of the Jap OEM market....

Been trying to download their catalogue to see if there may be a listing, fingers crossed though nets running sloooooow tonight, Ill report back tomorrow

Thanks for the reply, and the link, I need to learn more on the Delco as all that info on the delco website is out of my league atm. The Gems up and running again, took it to an auto electrician who found the carrier plate in the dizzy had collapsed. Theres a plastic "shim" in between two ...

Hello all, Delco 808 twin cam wont start, cranks but doesnt fire up... What sensors does the Delco 808 rely on when starting up? Have spark and fuel pressure at injector rail, and the timings OK All Ive done is replace the O 2 sensor since the last time it started and drove 6 weeks ago, the car has ...

If and when we happen to get to an ordering stage, Ill have 2 sets

Cheers

Todd

I was chatting to someone from Russell Jones' machine shop about having the twin cam balanced, he brought up that he has heard of people totally removing the 3rd cam in race motors...

Late reply....but been thinking of swapping front covers, I have a G200W case at home that I can use. Would I need to lift the head at all? Be rather tricky trying not to butcher that gasket at the front the chain passes through when putting new case back on. That episode with oil leaking from a hom...

Id take 2

Yeah its the early type, has a 32mm brass hex plug on end of timing case. Wondered how it worked as a tensioner once I had it out as there is only a light spring and what looks like the oil squirter for the chain. No wonder it rattles bad! Its not even a tensioner no? So if I ever take the head off ...

Little update on the twin cam......its still going! :lol: Have had my fair share of trouble with it though, gotta be a gem thing I reckon, anything gemini is bound to play up. The engine is still a ball to drive, it pulls in 3rd gear all the way from 50kms to 110km easily and I havent yet dared wind...

Whats the reason behind the intermittent timing chain rattle on start up....? Motor is a g180w. Most days it wont do it, some for a second or two, others it sounds like the chains going to snap! Peoples faces in the shopping centre carpark express my horror as it continues for up to 20-30 seconds. T...

Im running on my G180W,the standard sohc gem intank pump as a lift pump into a generic Bosch style pump, no surge tank just a fuel reg off a Camira also....

Well Ive put near 5000kms on the twin cam since late December.....thought Id update the thread for anyone interested. Hasnt been a smooth 4 months, have had a few problems along the way to deal with but nothing that has stopped it driving everyday to and from work etc. The 3 pulleys on the engine we...

Can anyone confirm how the vac. lines run on the 180W

ATM I have the dizzy and fuel reg. both running off the front of the plenum via a T piece.

Just after some confirmation....

Cheers

Todd.

good show todd...but u coulda used a diesel mount :D u gonna come to the skid pan? looks like there are gonna be 2 dohcs there! Haha on the mount, something to remember if mine splits....I never ended up using that fuel pickup I got from you either, its just running the Gem pump as a lift for the B...

Picked up another cheap twin cam, this one had been fitted to a Chevy LUV ute over ten years ago by a mate aiming to show the ute. Well ten years later I bought and scrapped the ute solely for the motor. The engine hadnt ran for over 2 years and looked rather weathered. I replaced a few sensor plugs...

LOL all sorted.... Ended up with a tiny filter off a Mazda 121 maybe? Fits perfect, the smaller size Im told should be fine, creating a tad higher oil pressure if anything. Anyone know if the 180W's cams are the same as the 200W's? Ill post some pics up over next few days of the conversion. Cheers T...

Alright motor is in and wired up with its Delco ecu from the Camira. Go to put the oil filter on and it hits the swaybar before even screwing on,cant even get close to the angle needed to get it on as the bars there....anyone else had this problem? Are there smaller, equivelent oil filters that are ...

1" fuel rail nice!

Get some photos up mate

Have you tried taking that big headed bolt on the drivers side off...its the one that sits on the side of the timing cover,where the metal oil feed line runs up from the oil filter housing....

Id start there maybe....good luck LOL

Todd

Just looking now at the G180W and it doesnt have that allen key bolt I mentioned...I was thinking of the G200W

Someone will come along and explain it....Elky!? haha
