I will be building this engine with a set of Jesse�s ported & polished heads with 3.0 litre valves & ST220 springs so that will need to be taken into consideration when adjusting the compression ratio on the pistons.
Not that I�m suggesting that $606 isn�t already a great price; but if more than 5 sets of pistons were sold in this group buy would the price get any better? It might make the difference between me buying one set or two.
Any reason you are going for forged pistons on an N/A 2.5 setup? Don't think it is all that necessary, and just increasing the CR by .5 won't give much power at all, maybe a 2% increase, if that! The only need to go with a higher CR is if you have a set of Cams that would benefit. With the cost of 2 sets of pistons and P&P heads + springs, you are 1/3 of the way to a Turbo kit... something to consider.
