Pistons In A 130hp 1.9

[chris1986 1]

just checking as i read some where that the 1.9cti had differant pistons and i want to make sure i don't have that one as its lower power right? my piston have like a little slope in the taken out does this sound like the 130hp engine. will have to take a picture really. also the little plate on the block says d6b if i remember that correctly.

have tried searching but on some post some people say one thing and something else on another so i just want to make sure

thanks

d6b is the 128bhp engine.

cheers mate i didn't know you could tel just by that. whats differant thought is it the cut out in the pistons? do you know what the code is for the lower powered one, so i know to look out for it

i think it's only d6b that had the 128bhp, they were p1 and p2 i think. the compresion ratios are different, which could equate to a dish/cut out in the piston.

ok, this one cam out of maybe a 92 ish 309 gti if that helps

The CTi engine had different pistons & a different cylinder head afaik.

 

There used to be a webpage that showed the full list of differences with pictures but last time I checked it was a dead url so I must've deleted it from my favorites.

The CTi has the DFZ engine. The pistons have a much smaller dish than the 130hp piston, and thus give a much higher CR when used with a 130hp head. They may even be identical to the 1.6L piston.

your pistons sound like the ones i have in my garden, there off of a d6b, i think it was a 309. i'm guessing that you CTi had an engine change.
