because the new H conrods (burton,maxspeeding ...) are normaly for piston with the gudgeon who spin free in the conrods and clips
and not pressed in

You need to have them modified to work.. But this leads to the next question.

Why spend money making std pistons weaker and risking your whole engine with nice new rods, without buying a set of forged pistons the correct CR for the power your trying to get. Pistons are very cheap now days if you find the correct source.

Yes i know. What about the low comp piston from woesner. 7,5:1
My spec is like 220-230 bhp because only have stage 2 turbo. But looking high boost like 18 psi

luxembourgrst

well I searched about what kind of comp are good for escort rs turbo and saw that std mahle rs turbo compression are enough low comp for -300 bhp

but now im fucked up I have the H conrods who only fit flushing piston with clips
but I want to stay in the standard 80mm bore?

what know hmmmmm

Yes standard CR will be fine as will those Wossner.

There is many choices of cr and sizes available for wossner, supertech, je, accralite to name a few. I prefer some over others for various reasons.

I would go for a slightly lower cr using the mfi setup or if you planned to change management systems in the future then maybe different again.

So really it comes down to your final goal you want to achieve.
If you build this nice forged emgine its a waste on mfi.

I know about the mfi

I agree with Jano, it is a waste, you may as well stay with stock internals.

well light piston an conrods also help in the bhp or torque?
there was mfi with 5 injector who get some 260-280 bhp (I know not with a stage 2 turbo ) in know that std piston are good for 300 bhp
but I need to change them because is more cheaper to buy forged piston as transformat the conrods to accept the standar piston...

If they are lighter you will reduce pumping losses so may free up some power, similar to fitting a lightened flywheel.

well here is the diffenrence

Well done. Now gap the rings proper and check comp ratio with dummy build.
