Isuzu G-series Twin Cam

I didnt want to risk the thing not sealing so i thought fook it, ill just coat it with the Hylomar. I only had one dowel on the block and was pressed for time so i was about worried about the gasket being damaged [unlikely, but like i said didnt want the risk] upon installation. Not worried about ha...

Use the Hylomar spray can shit - works the good. Rodeobob was telling me they sometimes use it to make up the difference/level out the block slightly on old trucks or some shit like that. You'd have to ask him but i just used it on a 4ZC1 and a brand new gasket and it looks the shit! Give it 10mins ...

Rod bolts are torque'd not tensioned

Get a torque wrench and the Gregories manual will tell you what torque to use on the bolts - rod/crank caps should be the same as SOHC.

Yeah the injectors ARE that expensive. Blame the stupid spray pattern being different because of the properties of the liquid being flowed. As for flow, fucked if i know. Shouldnt need to apply a coating to the bores to reduce wear - its simply a matter of researching a ring and bore-sleeve combo th...

Take a photo of the dizzy and ill tell you what you can/cant do with it.

Nick-

Dont feel guilty - the more knowledge the better really. The problem with Ethanol is it is a dry burning fuel. When the fuel/air mixture is drawn into the cylinders, some of the fuel slightly wets the bores and lubricates the rings. Its not enough to pass the scraper ring, but enough to keep the upp...

Why fuel only, you already have the electronic distributor whats stopping you?

Nick-

Yes you can but it would require some fucking around with the caliper mounts and brake lines - not overly involving. The trick is to grab a combo that comes close to fitting with little work. Apparently theres a certain Magna disc that pretty much bolts on with a certain Volvo caliper...pm F|sh on o...

You can use the standard pump to fill the surge tank, but you WILL need an EFI-high pressure pump. Grab one off a VL, you can get em for around 100 new.

Nick-

And as to DOHCs etc – its probably dead for the Wasp as she’s going back to her original owner now that I have Jaqi Jackeroo (after I fix her cracked head which she caught after RodeoBob delivered Jaqi here:- Jaqi had a pre-existing cracked head. Coincidence? I think not. RodeoBob knows how welcome...

If you want pictures of your various cars and any bits of interest posted up, send me an email with the pictures in question and ill post them up for you. The host i use is pretty reliable so it should be fine. I daresay 17MPG should easily be eclipseable with a properly intergrated EFI setup. The e...

FWD 4Z series. The Aska Irmscher R had the 4ZC1 Turbo, saw pics of one recently [if only i could find the pic] and the orientation looks strangely like the manifold above.

Nick-

It has now occured to me what this manifold is off. It is a factory type cast manifold [notice the mounts for the heatshield?] but it is DEFINATELY not a Piazza one. Drum roll please...

Isuzu Aska Turbo.

Nick-

That isnt a factory 4ZC1 Piazza manifold nor is it a SOHC G series manifold [square ports]. Could possibly be some sort of cast replacement for a 4Z, havent got my motors here so i cant check for you.

Nick-

Number 2 looks like the crankcase breather.

Number three looks like the oil filter and oil cooler setup as per 117Coupe.

Nick-

Um, Poida...

DOHC gaskets arent flat-faced. Only flat surface is the block, the sump itself is channeled - its much like a 4Z rocker cover gasket.

Nick-

Just pull it out. As long as your not twisting side to side there should be no way you'll break the practice. Maybe spray some CRC on the bottom of the rubber boot to help it out, or try push it out from underneath using a screw driver.

Nick-

Nice find Dan

If only HDT built it...

Nick-

you only need rubber EFI lines the current lines are not spose to be for EFO only carby and if your looking to be one the safe side or high hp i would suggest larger fuel piping (under the car) Never heard of a Gemini needing the standard steel fuel lines being upgraded. These are fine in 9second c...

You mean sleeve braided outside the hose? You wont need those.

High pressure EFI silicon hose.

Elky is coming to melbourne soon and has a whole heap of them. PM him, if he has space im sure hell bring some down.

Nick-

Mods needed to bolt in Dependant on version of engine.

What you after for the 117 Manifold?

Nick-

You had the "breadvan", the cream TD Van that you raced at Mallala right [i think thats the spelling?]. Welcome aboard and post some pics up of the Bellet, good to see some non-Geminis up here. Is the G200w running the standard injection system or an aftermarket setup? Shouldnt really matt...

I have a pair of GTR-copy manifolds (extended by a ~25mm) with twin 45mm Weber DCOEs on my 2L DOHC (in a Florian). (FYI - jetted correctly, DCOE 45's means 150HP instead of the standard 135HP EFI DOHC. Tates (a Melbourne mob that build racing engines etc) dyno tested my worn 2L DOHC at 135HP (100kW...
