1NZ / 2NZ Transmission Compatibility & Aftermarket 2NZ Rods
Hi all,
My first post here - but have got quite a lot of useful info just from reading here... I don't actually own a Yaris, or even a Toyota - but am in the midst of a complete rebuild of a 2004 Smart Roadster, using a completely built turbocharged 1NZFE. However, I'm looking instead at using the 2NZFE - although, a couple of questions holding me back. I know the 2NZ has a shorter block than the 1NZ - however, does anybody happen to know the following? - 2NZ connecting rod length and piston compression height. - whether or not transmissions that come with the 1NZ such as the C50 will bolt straight up to the 2NZ? And which transmission code comes with the 2NZ, looks like it's a C54? Another reason I ask, I work for a company who would be interested in developing rods for the 2NZFE that would allow one to run forged 1NZFE pistons - however, if the combination would ultimately mean using a short connecting rod - the accelerated bore wear wouldn't be worth it. Hope you guys can help! Cheers. |
