CP Pistons/Scat Rods for the R56 - Sorta

So recently i have been looking for pistons and rods as I see ours tend to have some issues.

In doing so it has been very hard to find them, until I start searching the Peugeot 207.. which ideally has the exact same motor as the R56 MCS.

Has anyone tried to put CP pistons in our car that are made for the Peugeot?

Pistons and rods will fit a pug or mini prince shortblock.

The rods you have listed look like they're for the previous generation Peugeots, but the pistons will work (R56 application is mentioned). That's some serious cash though, considering it only has 4 pistons. Has anyone ever heard of this company CP?

It's pointless swapping your factory OEM pistons until you either have a piston failure/detonation issue, or you know the exact cause of your stock OEM piston failure in the first place!

Simply swapping to an aftermarket piston, will not cure whatever issue, you or anyone else has, you must find the cause first.

If the CP's work then that's a decent option as long as the rings can be filled to a decent gap. Had problems with them over gapping from the start. IF some one does figure out they work for sure then I would get them state side. The exchange rate on the ones in the link would be killer.

The rods may be a little sketchy. Never been a fan of scat rods. Quality control is a little shaky.

Those CP pistons will NOT work with the stock OEM connecting rods, the stock connecting rods are trapezoidal and matched to the trapezoidal stock OEM pistons.

In order to utilise those CP pistons you will have to use them with those Scat connecting rods, or another flat square shouldered connecting rod, from another aftermarket company.

Yeah I was wondering if that was the case. That's how we designed our stuff, but I wasn't sure if the pics in the link were the actual rods or just a generic image of scat rods.

I posted these a couple months ago. They've seen some solid numbers on some of the EU cars. Needless to say Czar you're the man, the use of the scat rod or another with very similar specs is required. I don't recall anyone running these stateside but I've used each company separately on different projects. Its my understanding though that scat has improved dramatically over the last 10 years.

Raymazing,
I'm looking at trying to get about 280-290ish whp into my 2008 MCS. Will I be ok to keep the stock rods and piston heads without damaging or blowing my engine? If not, are they any options besides the connecting rods and pistons mentioned above?

What do you think about this rods??

Probably after reading the article about their similarity to stock THP rods, here: http://www.etuners.gr/en/index.php?s=12&t=301

Here is how you can make them fit.


First you need to machine the faces, 0.5mm on each side. That is because otherwise they will not fit on the crankshaft.

Then, you will need to machine 0.1-0.2mm from the outer sides of the connecting rod, where the bolts are. So that the rod can enter the combustion chamber. Otherwise they are wider than the diameter of the cylinder and cannot enter!

That's all ! I have installed these rods in my second engine using the modifications I described above.

Stock motor I'm sorry phone geeked I'm also running all aftermarket boost control. I would be a little more scared with the factory boost spikes in the mid range.
