It's just not worth it. Unless you have money to spend like a pro team. Maybe you should just reduce the weight of your Celica. It will have better the performance and you can bolt everything back in like the back seats, trunk assembly, jack, spare tire, run a minute of gas, lighter battery, lighter tires and wheels (if in the budget). I don't mess with a $6,000 dollar engine unless I can cover it longer than a couple of races or I'm rich, or I have sponsors.
Ok, thanks. Just wondering if it can be done, but I agree with you and would never go to the extreme, especially if it has something to do with the engine.
