how to find durability of pistons for high boost

[kevox]

So I need to buy some pistons SOON but I have no clue how to determine which ones will work safely with 15-20psi of boost....I'm getting the performance Eagle rods which are rated up to 800hp so I'll be fine there but I have no idea where to start with pistons....someone help me make the right choice!
Oh and the closer the compression to stock the better since I will be adding a turbo soon...

Well you need to be a bit more clear. What are your goals? 15-20 lbs of boost on a 14b comapired to a 3065 are two different stories. What turbo are you planning to run, are you going to spray, have you done the 6 bolt swap into your 2g. In all honestly if your goals arent huge I would look into doing the 6 bolt swap and for the $ you cant go wrong with the 2g pistons and 1g rod combo. Just need to give us a bit more info on your car, goals and such to help ya out.

Eagle rods were once rated at 600hp and are now rated at 900. Go to page 6 http://www.eaglerod.com/Honda_end.pdf :)

Also without goals in mind there is no way to help you. The stock motor is good for a over 500whp if tuned right.

Pretty much any namebrand aftermarket forged piston will meet your goals. Since you speak of adding a turbo later, I assume your talking about a 420a motor.

Some good links on piston technology.

I donno what 14b and 3065 are...? The turbo is the 20g I believe that Hahn sells...it's their highest model which cost $900 last time I checked. No spray, too risky for my pocket.

What is the 6bolt swap though? Here's the 800hp Eagle rods.... http://www.420a.cimotorsports.net/Engine%20Parts%20Pages/Connecting%20Rods%20Page/Eagle%20Rods%20Page/index.htm
Says they handle it, do they not?


My goals are nothing more than to have an extremely fun daily driver with the occasional drag-style driving from time to time....I'm not planning on taking it to the track.

Thanks man...I'll definitely read up on those a bit later when I get back from work!
How much hp can the stock crank support in most cases? I'm going to be getting my reconditioned at the local machine shop as well ...

Disregard my post... I read wrong and thought you already had a gst or gsx and didnt realize u were a 420a guy. Your best bet for ectensive info would be on 2gnt.com

teflon coated Mahle forged pistons.

Can you stop spreading MISS-information? :rolleyes:


Pick any forged piston for chrissake. Almost any will work.

If your 420a, most guys I've seen go with the Eagle Rods, JE Piston combo. Seem to be able to last anything your throw at it.
