I have had 3 soobs and only throttled a turbo version with an ea82. There is something different dramatically about all of them.
the 93 sedan at 84hp really stumped me until I found what oem did with the timing belt sprockets (manufactured off a "half tooth").
I have a guess at this point about the carbed model ea82 (1987 to be precise- I am sure there is a range of years) and there is no doubt at this point the actual cams valve timing is different. Anyone help with oem numbers such as below for a carbed ea82? The stroke is so tiny, the differences shown below are HUGE with a simple run proving it.
- intake valve timing open 10 degrees BTDC, close 54 degrees
- exhaust open 49 degrees close at 15
- 14 intake open, 56 closed
- 56 open exhaust, 14 close
I have a combo possible:
lower half of spfi block for pistons, carbed model cams in mpfi heads, scrapping mpfi for a carb mount on mpfi intake with carb disty., etc.
(I have mentioned I am not a turbo fan for the ea82-)
