Safe amount of HP for stock engine?

vipor · 01-25-2010, 09:13 AM

GT Motorsports® Hi-Rev Crank :96 mm stroke
GT Motorsports®-spec Arias®/Wiseco® Stage II FI pistons
GT Motorsports® Rods
Bore: 96mm (optionally 100mm bore with Darton MID sleeves)
Final Displacement (exact): 4.5 L

The 87.0mm stroke affords a major advantage; it can be dropped into an unmodified (i.e. unsleeved) block with no need for longer sleeves (that have to be notched to preserve the oil jets), as is the case with the 90mm stroke crank.

The Hi-Rev crankshaft is currently available only in 87.0mm stroke variety, with 90mm and 81.4mm (stock) stroke varieties becoming available in the next six weeks.

is there any other engine modification required for the stroker kit?

i can understand that with aftermarket pistons and rods, it will have a greater displacement.......

sorry for being ignorant, but just curious.

and, how much do these kits cost in general on average? installation cost?
