RE: Group a homologation questions
from the A-5180 papers.... 3 door/hatchback
1599cc max minimum rod mass - 431 grams - length 122mm - big end diameter 43mm (so no 42mm cranks!) minimum crank mass - 11540 grams flywheel cast iron minimum mass - 7060 grams 55mm T/B injectors in head (not in intake) maximum valve lift - 7.2mm - clearances .2mm, and .25mm number of intake manifold elements - 2 (TVIS plate and intake??) exhaust cast iron max intake valve diameter 30.7mm, 6mm stem max exhaust diameter 25.7mm, 6mm stem wet sump oil system As I read it... that leaves a LOT of room for special machining, and head porting. It also has cam lift listed... but not durations.... no mention of compression ratios either.... no mention of adjustable cam pulleys either.... Dan - You can |  .... OR you can ask for help!!!OST Porting service - http://hachiroku.net/forums/showthread.php?t=19991 |
