Buying Aftermarket Pistons

[matty.dc]

It looks like I will need some over sized pistons for the S52. Where are the best places to look for good quality and price for the pistons?

Thanks

I'd go JE or metric both are great quality but the prices reflect that, you'll probably be lookin at a grand or more for a set

CP are nice too i think vac carries them

If you ever plan to do a higher duration cam, try to get a set of pistons with larger valve reliefs.

Talk with Mike @ MaxPSI... he's a great guy to deal with... call him even if you have questions... Great pricing too

No vac motorsports....call MaximumPsi and order up some custom wiseco pistons.Mike will probably have the best prices. Or hit up Import performance parts they got good deals on wiseco pistons for under 1k.
