chris1986 1 Posted January 29, 2007 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 Share this post Link to post Share on other sites

chris1986 1 Posted January 29, 2007 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 Share this post Link to post Share on other sites
brianthemagical 1 Posted January 29, 2007 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. Share this post Link to post Share on other sites

pug_ham 244 3 Cars Posted January 29, 2007 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. Graham.

petert 587 Posted January 30, 2007 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. Share this post Link to post Share on other sites
brianthemagical 1 Posted January 30, 2007 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. Share this post Link to post Share on other sites
