Mods needed to bolt in

Dependant on version of engine. For G200w ex-JR130 Piazza [front mounted oil filter] - bolt in

For G200w ex-117 Coupe [mid mounted oil filter] - diesel Gemini crossmember then bolt in.

gearbox

C series ISUZU Diesel bellhousing or G series DOHC bellhousing

ANY G series or 4Z series RWD gearbox. Remove front housing/bellhousing and replace with C-diesel or G-Dohc front half.

1300 bucks will get you a running engine in good condition. Add money on top for wiring, ecu, fuel system modifications etc.

If you get one with a working ECU (stock or aftermarket) it should save you a lot of money.

Twincam needs: surge tank, EFI lines, TPS, recored radiator, hoses, assemble the ECU (50% done).

And yeah you'll need EFI fuel lines (braided) and if you want to do it half properly a new fuel pump and surge tank.

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

High pressure EFI silicon hose.

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 cars so i dont see how a standard DOHC would need more :wink:

Fuel lines are steel standard? Does this mean you don't need EFI lines?

I was told EFI lines are braided - but there you go, learn something new everyday, makes a big difference when you hear it from a car nut and not a business trying to make money.

The steel supply lines will be suitable for EFI applications but all rubber joiner sections should be replaced. You will also need to replace the original clip type clamps used to retain the flexible hose. You can find special EFI rated fuel clamps in spare parts shops.

I recommend changing all the flexible sections with the same type of hose to avoid making mistakes. It's ok to use EFI rated hose in low pressure sections but not ok to use non EFI hose in high pressure sections.

Low pressure fuel hose will have the marking SAE30R7 (50psi rated/250psi burst pressure) clearly marked on it. It is suitable for applications where you are using a carburettor or low pressure return/vent lines.

High pressure EFI fuel hose will be marked SAE30R9 (225psi rated/900psi burst pressure) and MUST be used in all high pressure sections of an EFI application. As I suggested, use it in the low pressure return/vent sections as well to reduce any chance of accidemtly fitting low pressure hose.
