Today, the new turbo manifold was modified and installed and then a rough charge pipe was created for testing purposes. Also note the compressor blade on the turbo. This close picture is going to be used as a before image to test the wear on the wheel for pre turbo water injection.

That is exactly what I am doing to project 240sx by adding an over the top intake manifold from a Nissan Pulsar. Since the CA18DET will use water injection as its only form of intercooling, the boost pipe can be made as short and direct as possible. And in this case, the...

Here we have the mock-up of the new manifold I am making. It basically borrows a few ideas from both the log and equal length manifold designs to make what will be a very responsive manifold that won’t suffer in higher rpm ranges. And don’t worry, the finished product will be much prettier.

The What and Why of Welding the Differential. Most 240sx’s come equipped with what is called an open differential. An open differential is designed with four gears set inside a casing that is rotated by the driveshaft. One gear connects to each output shaft and the remaining two gears connect to a center pinion and rotate in opposite directions perpendicular to the rotation of the casing...

I suggest you look at it this way, if your car is registered with your state and driven on public roads, you cannot do this. On the other hand, if you own a dedicated track car that is trailered when on public roads and not required...

I found these scans the other day at (link coming). They are scans from High Performance Imports, a Euro car magazine, and they offer a lot of info on the CA18DET.
