the obvious choice is the 3.0L, but all that BASICALLY does is increase the stroke. bore x stroke of stock 2.5L is 3.33 x 2.92 and in the 3.0L it's 3.39 x 3.39.
Actually; stroke stays the same! Same crank, just bigger bore! (Also same deck height, piston compression depth, & connecting rods)
All 2.5L & 3L engines have a 79.5mm Stroke
Through 99 2.5L's have a 82.3mm Bore
00 and up 2.5L's have a 81.67mm Bore
All 3L's have a 89mm Bore
Raising redline past a certain point (about 7500rpm) would get exponentionally expensive!!!
The amount of engine work and custom parts needed would add up very quickly!
