Getting rid of the stock 3T GTE dizzy

Not only is the 3T GTE dizzy big, its also expensive and also makes it hard to fit a front mounted throttle body. Given I plan to make a custom plenum with front mounted throttle body I needed to do something about the dizzy. I got hold of a complete dizzy with crank angle sensor from a 3S-GTE.

I pulled it apart and after a bit of engineering, I managed to modify it to fit into the 3T GTE block.

The top shaft is out of the 3SGTE unit, I needed to get the 24 tooth gear to fit onto the 3T GTE shaft which is the lower shaft. As you can see, I had to turn the shaft down to create a press fit for the gear wheel.

Then I cut the 3S GTE dizzy in half and machined the base complete with spigot so I could fit in onto a stock 3T GTE dizzy base.

Here's the 3T GTE dizzy that I also cut in half and machined to match the 3S GTE dizzy top. See the 3 tapped holes I made to bolt the 2 pieces together.

Here is the 3S GTE top and 3T GTE base bolted together.

This is the end result. All that I need to do now is to make a cap of some sort. Most likely out of aluminium so I can polish it up.

With this set up I can now run full sequential injection. This also does away with the stock coils. So once I have external coil packs and this on my engine I will have plenty of room to make way for my custom plenum.
