Well ... the point is that i am a drag racer and till now i have used c20xe engine in class A(engines up to 2000cc) . Next year there will not be class A any more cause they put it together with class B (2000cc- 3000cc), so there is no chance to win this class with normally aspirated c20xe . I thought that maybe i should build turbo ohc 2,0 so if there are any experience with thiese u guys would share them. Lets say we totally rebuild it ...how many horsepower. Yeah i know 16v turbos make ca. 1000hp but it is like REALLY expensive too, ohc would be alot cheaper to build(and cheaper to replace if it blows up). So highly tuned OHC 2,0 turbo ....how many horsepower would it produce???
