Owner reviews for pistons

The kolbenschmidts are coated side skirts as well which is great for cyl bore wear. Few mk4 blocks I grabbed had perfect cyl bores even at high mileage.

Ya, I recommend Mahle's for most builds. In fact we like them so much that we had a some custom made on a heavier duty forging, with a heavier duty wrist pin- so we can use them on bigger power builds then the standard PowerPak pistons which are actually somewhat light duty.

get a set of mahle 4032 alloy pistons unless you're going for very high power levels. you'll barely hear bad things from 2618 alloy piston owners, but 2618's have been known to piston-slap on cold starts, depending on the tolerances of the build.

I stroked mine out to 2.1L in 2012 using ALH (TDI) crank. It's the best upgrade I've done to the car outside of a BT. I never heard of a stroked engine running hotter than stock. My coolant temp is always at stock 190 F.

For what it's worth, I had a balance shaft/oil pump belt break and get caught up in the timing belt on my '94 Galant. This caused the timing belt to skip several teeth (who knows how far) and bent all the valves. It left damage on all pistons, somewhat similar to the damage I see here. I smacked a head on it from the junk yard and proceeded to drive it another 15k miles without any related trouble.

Here's an update for anyone that might find this useful in the future. I ended up sticking with the 1.8 crank and my JE forged 7.4cc 9A pistons in my PL block. I decked a massive .115" from the block resulting in a deck clearance of -.011" (pistons stick out a bit). This should give a CR of 8.65:1 with these 7.4cc pistons, ABA head gasket, and my 47cc combustion chambers.

JE are the best pistons on the market hands down. I know from personal experience. The OEM rods rifeled and ARP bolts will hold 400whp so no need to upgrade for your NA but Pistons are a must for a quality build.

I am only running stock and used stainless steel, also have had the DNJ pistons in mine now for about 2 years and they appear to hanging in there at least on stock power. I did switch the rings to Total Seal rings and not DNJ, don't know if that made a difference or not but it felt like a better choice.

mio fratello ha una Golf VII 1,4 TSI acquistata nel 2013.

Avevo scritto anche qua un paio di anni fa perché cominciava a bere molto olio, ad ora è arrivato a consumare 1kg ogni 500km.

The piston was given to me by a friend who got it from a Dodge dealership. The defect has something to do with the wrist pin, it seems to be stuck partly-pressed in, further in one side than out the other.
