Im in the market for rods and pistons, and Im planning to get Manley's, but Im not sure if I should get I beam or the tri-beam ones.

Any input from the experts?

Decided to pull the trigger on Manley's pistons, upgraded pins and standard tri-beam rods. Linked discussion helped a lot! Thks Haul! 

Build will be an Alpha10 turbo kit. I will also get AMS cams and Kelford Beehive springs as well. 

 

I'm still debating if I should do oversize valves or not. I don't think they would add that much WHP to an A10 setup. What do you guys think?

Good choice. During the discussion haul linked and subsequent research I have not found any reason to go with standard Manley rods over the Tri Beam. I often wonder why they even make both but have to assume it has to do with the drop in claim of the standard rods at 720g weight. The Tri Beam is almost an ounce heavier at 745g so they can't claim drop in.

Would I see any benefit in an Alpha 10 build?

I don't think I would go bigger than A10 for a while since I daily drive my GTR.

Not necessarily but i also said at 1 time i don't see me going bigger than a  A-9 and I'm upto a A-14 so never say never. :)

This way your just future proofing your build and the extra insurance would be worth it to me.

Did manley change something with their vr38 rod lineup? Ordered i beams and received tri beams. Box has the number with the i beams on it but inside were the tri beams.
