Isuzu G-series Twin Cam

Just wondering if someone could measure the distance between the rocker cover to bonnet, and side of head to shock tower for me as my engine isnt in the car. Im playing around with the idea of reverse-mounting the standard exhaust manifold and mounting a turbo on it.

Its been a while since ive done the indicators, to the point where i cant remember what they looked like. From what i can remember, the Gemini hole is too big and the lense and backing will need to be glued onto the quarter. As for the plug, all that was needed was abit of filing on the backing of t...

Picked up the engine today, have to say im very impressed with the condition of the crank, bores and in particular, the cam bearings! They look as new.

Missing the engine mounts and oil cap though

Nick-

Dont happen to have the standard engine mounts on them do they? Or the oil cap for the rocker cover?

Nick-

Yes they are/were AU indicators, reverse mounted so the pointy end aims towards the back of the car. All you need is some Stickaflek and they fit, i think even the plug clipped in with abit of fiddling. Tail lights were TD SL\E, I now have TX Coupe tail lights [not on the car] much like your mates. ...

May be time to formally introduce my car as im picking up my engine tommorow morning... Bought it off another forum member in a fairly sad state. Was originally a TD SL\E Coupe in a faded-and-cracked Atlantis blue duco. My initial thoughts were to respray it in the standard colour and get it on the ...

The valves are as big as you can fit. The ports have been modified. The lift is very high. You might spend a $1000 on a flow bench again for maybe a 10-15hp gain. A 16 valve head will flow so much more due to the valve area. One thing to remember just because it doesn't have as much power as a sr20...

They go for about 400-600 second hand, pretty common and easy to come by. Yella Terra sells the same charger brand new for about 1500 i think.

The supercharger off the 4AGZE is the SC12, while the one off the 1GGZE is the SC14. Both are positive displacement, the SC12 displacing 1.2L of air, the SC14 1.4L. Both are extreemly inefficient, crude, hot running and not worth the hassle. A turbo setup is a better option. BUT... If you MUST go fo...

Told you i was pretty sure the crank bolt pattern was the same :wink: Never doubt me again fark ya. lol G161/180 clutch's are 200mm from memory, bolt pattern is the same as the G200 one so these should bolt on too. Go the G200, bigger flywheel = bigger clutch, bigger clutch =....well, you know. Nick-

As Denny said, the reason G series engines run on ULP without a drama [with the exception of ignition timing that is] is because they were built to run on it. We got the G161/180/200 as per Japan specs, and seeing as they had ULP for ages it means that Leaded didnt really affect the engine much othe...

Get the G200 one, its bigger meaning better clutch/better power handling.

Might be of some more assistance. From what ive seen, the airbox and filter is identical to that used in the Piazza and i *think* TF Rodeos. Not to worry though, you could use something like a VL Airbox which fits perfectly in the battery tray area, or perhaps on the firewall recess. As for the actu...

Simple enough answer to that question. The reason they cost so much to tune is because they cant be done in "real time". With an aftermarket ecu, the tuner makes adjustments on the lap top. With the Delco, you make the adjustment THEN burn it on the memcal, then it takes effect. The downsi...

Someone is already ahead of you... http://turing.une.edu.au/~ashley/gemini/forum/viewtopic.php?t=95 Rod bearings - G series SOHC Crank bearings - G series SOHC Dummy cam bearings - G150/160 Pushrod engine [Bellet] Someone correct if the above are wrong.

I should point out that i dont actually OWN a DOHC as yet. I am looking at building a G200W with custom made forged pistons, balancing work, headwork, custom made EFI plenum [similar in design to the 117 item] and a GT28RS turbo, however its been put on the back burner until i can find a sollution f...

Its a G200W so itd have the I-TEC setup meaning CAS dizzy and hotwire AFM [unless ofcourse, its a 117 Engine. Which way does the throttle body point? Im going to assume its the I-TEC engine so here goes. Basically, any fuel/ignition ECU would be good. What sort of budget do you have? What do you wan...

Post some pics of what its in etc :wink: I came close to buyinga G200 DOHC for my Gemini a few months ago. Bloke wanted 200 for a mainly dissassembled and missing G200. Turns out it was originally out of a 117 [judging by the oil filter location]. Manifolds [both exhaust and inlet] were missing as w...

Heres some more. JR130 Piazza. Thrashed to within an inch of its life. http://img.photobucket.com/albums/v403/isuzugemini/Piazza/jr130import02.jpg PF60 Gemini G180W http://img.photobucket.com/albums/v403/isuzugemini/Piazza/zzr7.jpg PF60 Gemini G180W - TURBO! http://img.photobucket.com/albums/v403/is...

Bastard, i was going to start a basic post but you beat me to it. :P Anyhow, there were/are two different G200W engines availible from Isuzu cars. The first was found in the relatively rare hand made Isuzu 117 Coupe, while the later is from a JR130 Isuzu Piazza. Most major components are the same ho...

Ive got one Poida but its to suit a 4ZC1 Turbo. Give Elky a buzz he seems to have a few DOHC's.
