Test Engine - Page 2

One of my projects is to build a modular engine control system. This project will be the final test of that system, a working engine. I decided to use the same engine that is in my Hyundai Tiburon turbo project as I'm familiar with it. I will also be able to compare the tune of my system to that of the ECU installed in my car.

I have already put the majority of the engine together and installed it on the test stand. There is a lot of work still to do before I can even think about starting the engine. I have placed the engine block on the stand, next is to attach the transmission. I blasted the outside of the transmission since it was in such dirty condition. I found the old flywheel I used in my daily driver, it used to slip on boost.

I always thought that the flywheel needed to be resurfaced again. I attacked it with some sandpaper which removed most of the blueing, of course the heat spots are still there but it is in far better condition than I thought.

I had previously machined the nose out from 35 to 41mm in order to fit my engine, but this test engine being newer used the smaller 35mm spindle nose. I machined a bush and pressed it in place, I should have no issues with this.

I installed the flywheel with the old clutch, it's only for testing purpose. If I do use this engine then I'll be sure to upgrade the clutch.

The clutch bearing is also pretty worn out, but I'll worry about that at a later date. The transmission was installed on the stand, it actually required me to remove the block. I purchased an engine hoist which made things so much easier, it will also help me in the future.

The timing belt installed and set correctly. I cleaned up an old starter motor and installed that so I could turn over the engine.

I made a huge mistake in that the stand frame is in the way of the stock oil filter. As a side project I machined a part to relocate the oil filter, it also allowed me to use a much larger than stock filter. I filled up the filter with oil before installation and then filled the oil sump with oil. I turned over the engine with a ratchet before installing the oil filter to ensure oil was flowing. Once I was happy I then turned over the engine for ten seconds on the starter motor, this would make sure the whole system is full of oil.

End of Project

This project was destined to run on my modular ECU, however something more important came up. I built an engine for my Hyundai Tiburon Turbo project very similar to this. I needed the space so chose to sell the car, but with the modifications that proved to be very difficult. Instead I removed the engine and then installed this as a replacement. I figured a totally stock car with a newly rebuilt engine would be a lot easier to sell.

As for this project, it is over. I will definitely need an engine to trial out my ECU, but it does not matter what scale it is. I will instead choose something a lot easier to work on, that will be an air-cooled motorcycle engine. I can test higher engine speeds while not have to worry about storage.

Take a look through my Hyundai Tiburon Projects to see how this engine worked out.
