so in my quest to understand the almighty turbo, I have a question regarding engine managment or lack therof.
I know a few people have swapped modded 2.5L OBD2 engines into 1.8L OBD1 cars. They did this by simply switching the old sensors onto the new engine (as all of the plug ins are the same).
I also calculated the HP output of a stock legasy turbo to be roughly a 25% HP gain (the stock 2.2 puts out about 130, even with the lower compression of the turbo lock, I figure somewhere in the 120-125 range). The stock leggy SS puts out 160. calculated out, that's: 128%-133%.
so in my mind...calculated out, the same setup on a 1.8L engine would be: 141-146 HP
would you really need engine managment for this? couldn't the mass airflow sensor keep up with the extra power? couldn't the injectors keep up easily? please let me know what the problems would be. I expect it would run a little rich, but again, Im looking for imput from you guys. thanks!
