yeh those measurements that xflow has put up are wrong, the intech and e series engine have the same bore and stroke as the ba-bf engine.

Stroke changes, but swept engine capacity has not...??? WTF? How does this work... Stroke Hasn't changed since the crossflow days of 99.31mm.... was about to say the same thing. the assembled length of the BA/BF rod and piston, when installed in an e serries block puts the piston about 17thou down at TDC. to use a barra turbo piston you have to have valve reliefs machined in the right spot |

Sfa valve notch with low comp pistons...
The AU engine has the same rod length as BA engine.. Its just the pin size thats different..

$1550 I have built a few engines with these pistons... My Dart 330 has them, an MX6 we built and now a 1UZ 4.0 V8 Lexus.. Rings come with them so it leaves NO worries over which rings to get!!
Chrome Molly is a no no with forced motors apparently!!!

We have two spare engines.. We worked it out to be 8.5 compression.. Too close to new years for exact CC...
