2 bolt 4 bolt???

how can you tell the difference between the two... i kno that the 4 bolt is better but which models have which?
thanks, harry

93+ is a 4 bolt. And its not really better than then 2 bolt. It is stronger but there are PLENTY of high hp set ups on 2 bolts without a problem.

Every NA is 2 bolt
91-92 TT models are 2 bolt
93+ TT models are 4 bolt

Every 91-92 car has a cast crank and connecting rods
Every 93+ car has a forged crank and connecting rods.

Only flaw I see there is I beleive all DOHC's all years had forged rods. Could be wrong but I swear I just read it the other day.
