|After I'd purchased my red '93 Turbo, I decided to strip the
wrecked white car, rebuild the engine,
and put it in the new car. The opportunity to rebuild the engine out of the car, with no
deadline to finish it, enabled me to plan the changes I wanted to make
over a period of time.
Little did I know how long this project would stretch out. It took a full year before I had my turbo kit! I used that time to collect parts I thought I would need to build it up the way I wanted it.
This project can be divided into three parts: removing the engine, rebuilding the engine, and installing the engine. The BGB, while not without errors, is a valuable resource and should be at your side during this process. Trying to do any type of work on the MR2 without consulting the BGB will likely lead to frustration and possibly disaster. While imperfect, it's better than most other service manuals I have worked with.
Remember that this is only a guide -- not gospel. What you do to YOUR vehicle is YOUR responsibility. I do not endorse, approve, authorize, or otherwise encourage you to make alterations to your vehicle. Be careful, and recognize the dangers associated with modifications to your vehicle's critical systems, like electrical, engine, brakes, etc.
Like any project, planning is essential. And like most projects I've undertaken, my planning could have been better. Determining all the required parts in advance, having them on hand, tracking them so you can find them when you need to, these are all tasks that I could have done better. As a result, I have a few suggestions:
I don't list torque values, not because they are not important but precisely the opposite -- they are important enough that I'm reluctant to provide values that might be incorrect. The BGB should be your source, but use common sense, as the BGB has errors as well. The BGB does include "standard" torque values for standard-size bolts, and these are useful as general guidelines. For example, if the BGB advises you to use 60 foot-pounds on a 10mm nut, find a confirming source. It's likely you'll end up with a snapped stud or, worse, a stripped hole.
These pages have LOTS of photos. That's really the whole point in creating this guide. Owner's manuals are often lacking photos, or they have a small, fuzzy, B&W photo that doesn't quite show that crucial detail you need to see. All images can be viewed full-size (1024 x 768) by clicking on the smaller image. The full-size view can often provide that extra level of detail necessary to clarify the operation. I could be accused of including more photos than necessary (especially on relatively simple tasks), but my philosophy has been "it's better to have it and not need it, than need it and not have it".
I use the photos as a reminder to myself. I often get interrupted during a project and can't return to it for days, even weeks. The photos can prove invaluable when trying to remember what I've done.
Some of the photos might not exactly match the sequence of the text, as I may have used photos from previous projects that I felt better illustrated the task at hand. So the car in the photo could be white or red, but the task was the important thing.
me if you have comments or suggestions about the article or the
project, or if you find errors on these pages.
