Hi!
I need the GA16DE (gen 2) stock cams information, ex. duration & lift. I want create a custom cams but i need the stock duration and lift to create the cams for my aplication.

Thanks!

Look in the FSM ?

Alfsentra, you will be able to use the same cam gears on either gen. It doesn't matter if the lift or duration are different between the two. I will look up the 2nd gen and see the difference out of curiosity.

^Those are the 1st gen cams though right? 91-94 then 95-99.

The cam gears are the same, 91-94' / 95-99'

Wow! Intake lift vs. Exhaust lift. Very bad exhaust cam.

Intake: .342" valve lift - 208* duration @ .050"
Exhaust: .312" valve lift - 196* duration @ .050"

Lobe separation angle is 115.5* (static). It changes due to the variable cam timing during engine operation.

I understood the change from the early 105 Hp GA to the 115 HP was all port and intake manifold. BUT I do not know for sure the Cams are the same, i have not seen any comments either way.

^That's not that bad, the intake can be more at times. It's like that on the 95-98 200sx SE-R's. That's why they buy the 91-93 SE-R intake cam to bump there HP's up 5-7.

^You are right, the HP is different. I heard that the cam gears were the difference, but again, I'll have to look this info up.

I know that the 95+ later GA16 had bigger intake ports, single compression rings on the pistons (instead of two compression rings...less friction), and a different intake manifold. I seem to recall the factory ignition timing spec was different as well, compared to the '91-'94's.
