do I need forged pistions?
my 200 I6 will be turbocharged to 6 PSI running 8.2:1 static comp ratio, also will be fuel injected, and timing will be retarded when boost comes up. will I need forged pistions? I can get forged custom to my specs Ross Racing Forged Pistions for $589 per set of 6 including pistion pins and rings, but I can get a standard rebuild kit with stock cast pistions for $336, $17 more with moly ringsYou don't know what you've got til it's gone

gosh matt i am no expert on this but i would think if your going to cram 6 psi into a 200 i shure would get forged pistons to keep it together.

I was thinking that way. the guys on the Ford 6 forums think that stock cast pistions will hold fine but, just seems like there not enough.You don't know what you've got til it's gone

They may or may not be enough. However, is the $236 difference worth the insurance?Jack

well, I don't know, I know the rebuild kit W/O pistions is $207 I think. but if I sent the stockers into meltdown from going lean under boost and a rod went thru the block, that's a bit more than a $236 but then again the forged pistions could do the same. I don't know is it worth it?

The forged pistons are stronger, less likely to fail, and you're only talking about a couple hundred bucks. I think you know the answer already.

yep. I can have them any way I want too, there made to order. If I cannot get a rebuilt larger chamber head so far ( 2 rebuild companys, the 1 that Advance auto deals with and Marshall engines, both have no cores of the better EO casting head, I'll keep going back thru the years but I don't have my hopes up), I'll get the pistions with a 10cc dish, the better heads have 10cc more in combustion chamber volume, I'd just need to make that up.

IMO forged pistons are just like insurance..... You probably don't have to have it, but do you really want to take the risk??? I'd say go with the forged, get here all dialed in, then if you want to up the boost or put some NOX to it the bottom end is ready for it...Yesterday is history, tomorrow is a mystery, Live for Today!

Nice photos!
If you can afford to build a blown motor don't skimp out on the pistons for heavens sake.

Not sure a billet block would have kept that one together!!!!!

You will notice that the steering wheel is mounted to the tractor cowl, wonder what it felt like to have the steering wheel jump out of your hands like that ?
Maybe the expression on the guys face says it all
