Meh, the engine these cars have in them are cheap enough to buy a spare and do it, which just gave me a good idea... hmmm

I have some pdf's on the 1NZ-FXE (Prius motor) and the specs are ever so slightly different for the Prius piston diameter but everything seems to be the same.
Not sure on what sort of timing advance the Prius runs compared to a 1NZz-FE though.

Tamago · 11-09-2008, 06:06 PM

didn't read the whole thread but...

the 1nzfxe in the prius is not a normal 4stroke engine.. but hey, as long as the valves clear the pistons and the connecting rods are of the same length, you should be OK

cali yaris · 11-09-2008, 07:34 PM

this Prius piston discussion is just to save money, right? Because you could order pistons from CP with any specs you want, including high compression for the 1NZ-FE

06silveryaris · 11-09-2008, 07:39 PM

as far as the prius pistons what concerns me but just very little would be the fact of pinning. Can the factory ECU make the fuel adjustment or would just running higher octane cure it if it happened? As far as ITB's go with the yaris engine being smaller you can probably use GSX-R itb's and make a manifold once the drive by wire issue is solved. I have a very close friend that had been making manifolds for ITB's for Hondas for quite some time and they work out nicely. I can post some pics of he last one he made for a integra once I figuere out how to make the pics smaller or I can email if you PM me.

06silveryaris · 11-09-2008, 07:45 PM

Sounds good! Hace tiempo que quiero janguiar con pal de yaris y esto de los pistones de Prius puede Bregar. Yo tenia un 4A-FE con pistones 7A y UFF!

kargoboy · 11-10-2008, 06:13 PM

CP should be releasing Pistons for the 1NZ-FE shortly. At least, that's what my supplier is
telling me.

Flipper_1938 · 07-28-2011, 04:31 PM

Did anybody ever lay there hands on a set of prius pistons to see what the difference was between those and the Yaris pistons?

cali yaris · 07-28-2011, 05:05 PM

I think it was determined that they are not compatible.
