Brian, Have you seen this combo and have any data?


It is only a guess but starting at stock with about 280hp I would think about 5-15hp for a sport muffler, 10-15 hp for .9 bar boost. Maybe another 10-20hp for a better intercooler. If SC cams another 10hp maybe. Headers, 10hp or a bit more on an 89. Again, only a guess.


After changing out the muffler changing out the turbo would probably be the next best candidate to be changed if looking for less lag and more HP. I suspect the stock turbo is not very efficient much past 300chp.
