Hi there everyone i need some help choosing a piston for my scoob i have engine trouble and i am going down the 2.1 stroker route but i am not aiming for megga bhp just 450-500 bhp and i would like to know your experience of piston makes what ones should i buy ...mahle/cosworth/je/wiseco or wossner ??? any help would be great there is not a great difference in price

 

I would go for any of the following.

Cosworth, Wiseco, Mahle, JE.

 

thanks buddy engine will be out next weekend and i think im gonna find a melted piston driver side of my engine has a ticking/knocking noise deffo not coming from crank as driver side much louder than block centre when i put metal bar between my ear and engine i am ready for engine hoist i have had rocker cover off and valve clearance is perfect and valve movement looks good my car has only done 40000 mile but i was running a little to much boost for standard pistons 1.7 bar ish standard pistons and trackday didnt work

 

Cosworth do some quality stroker pistons to be used with standard length rods - had no issues whatsoever with them on the stroker builds I have done.

Hi Ian

We are running on our wagon 2.1 stroker with Cosworth pistons and Manley rods and is good combo for 500-550bhp,for more you will need I beam rods

I'm currently looking at Wiseco Piston/Crower rod combo on realstreet

I am currently with Wiseco piston and manley rods combo, bought from RSP.

 

Many thanks guys. Cosworth does have a nice ring to it

 

using mahle pistons and manley rods on my build, good bits of kit as with most above posted

 

Wiseco pistons and manley rods in mine,been very good although wiseco are quite noisey pistons when cold.

 

Thanks guys im not sure wiseco are for me then cold start noise will put me off or are all forged pistons a little noisy on start up because of heat expansion i did read that mahle only need 2 Thou running clearance and some needed 3 or even 4 Thou clearance

 

Every forged piston needs some clearance when cold Ian,if there isn't a little noise from cold then it will probably run tight and over heat when hot.

 

nice one ok i will have to put up with a lttle noise when cold then what about compression ratio lots of different crowns styles out there

 

best to talk to your engine builder Ian about that
