One of the reasons for turboing it was to get a siqnificant increase in hp---------If you can't make the motor bigger you need to supercharge it---one method is turbos------- There is no way reasonably possible to increase the size of a 3 liter engine to get enough HP to make a really big change on the STREET--------however, if you are going to CLASS race it where you must be NA and stock type engine you could get this one out to around 3.500 and stay with your stock stroke crank--- you'll only pick up 4 or 5 cubes.

If you are going to STREET race stop lite against other ricers, change the heads and add the turbos----- Or put a hemi in it !!!!!!!!!

Really----just about half way down on my first cup of coffee---------you will not increase the size of a small 3.0 liter block enough to go the expence--------Swap in late model alum V8

Hemi or Ford won't fit---you'll need to do LS type
