Group a homologation questions

[oldeskewltoy]

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....
