    1993 VAF to MAF conversion & Turbo

    Yes still have it, it's still alive and running. It doesn't get a whole lot of use, but did 2000 odd KM's in it over a couple of days recently towing 1800kg. Still goes as good as it did when first built. The transmission let go a few years ago, so that has been fully rebuilt with extra clutch...

    1993 VAF to MAF conversion & Turbo

    Hi, a factory engine oil cooler are you talking? As far as I can see there isn't one. I used a sandwich plate under the oil filter with an inbuilt thermostat, so just remote oil cooler from there. The automatic transmission oil cooler from factory is in the bottom of the radiator. I just pulled...

    1993 VAF to MAF conversion & Turbo

    Time for a bit of an update. I'll start with saying every project has its issues but that is why it is a project. The previous owner never ran glycol (anti-freeze / anti-boil) in the radiator. So one of the head gasket steel rings around one of the cylinders let go and showing as over heating...

    Yes I did have some issues running lean from about 3800RPM onwards. I've fixed that though. I'll have to look into the voltage next time I have the laptop plugged in.

    1993 VAF to MAF conversion & Turbo

    Time for an update. The Fuel pump switch diagrams I put above, didn't work. Well I couldn't get it working. Talked to a friend and he threw it in the bin for me and programmed up an Andruno. Full logically controlled fuel pump switching I have now. Don't ask me about this as all I know is it...

    1993 VAF to MAF conversion & Turbo

    This is as far as I have got so far. Turbo is currently being installed, in spare time. And I need to build the circuit board above. Have got all the components ordered. I always mount the oil feed off a flexi line as if that small line breaks its all over pretty quickly. I learnt this from...

    1993 VAF to MAF conversion & Turbo

    You will notice in the diagrams that the VAF has a built in fuel pump switch so that when the flapper first moves open on the initial crank of the engine the fuel pump is told to start running. The MAF does not have this feature, so I asked for Pin help here. Attached is what he said most of the...

    1993 VAF to MAF conversion & Turbo

    The wiring pin outs I used. I could never find the pin out for the MAF airflow meter in any of the Manuals. I think I ended up finding it on the original, VAF to MAF conversion forum on here.

    1993 VAF to MAF conversion & Turbo

    Pin the creator also looked at my data logs, I have some interference issues that I need to fix up before I do anymore running. I'm using shielded wiring so will earth all the shields. Moving all the power sources and grounds as close to the ECU he has also advised. His comments here: If you...

    Photo's of the first stage install the initial tune that was very rough. Graph also of the finish tune for now, will continue once the turbo is installed.

    1993 VAF to MAF conversion & Turbo

    My aim with this conversion is to better improve the metering of the air volume going into the engine and to stop the tendency for the VAF unit leaning the AFR at high RPM. The reason I want to fix this AFR at high RPM is I plan to install a turbo setup. There are many options out there where...

    93-94 truck VAF to MAF conversion project

    Hey Chris, I basiclly went with the Turbo Glide in the end because AXT stopped talking to me so they lost the business. I would have one AXT as they were willing to only sell me the bits I wanted, Turbo Glide would only sell me there complete setup, so a few of there bits are not going to be...

    It is a Turbo Glide full setup. I wanted a good long lasting cat manifold that will last the distance. The choice was Turbo Glide, AXT turbo or a couple from the States. I chose to go full setup as you can't garrentee turbo center lines if they will all fit if your not getting a kit
