What do you want? I have the complete spec on them (homolgation papers are
very detailed).

EG:
Basic Circumfrence: 34.00 mm
Inlet lobe 39.5mm
Exhaust lobe 39.5mm
Timing:
Valve opens Inlet: 20 deg before btc Exhaust: 60 deg Before BDC
Valve closes Inlet 60 deg after BDC Exhaust: 20 deg After TDC

Cam lift:
Inlet:
- 5 deg 5.5 mm
- 10 deg 5.3 mm
- 15 deg 5.0 mm
- 30 deg 3.5 mm
- 45 deg 1.2 mm
- 60 deg .3 mm
- 75 deg .1 mm
+ 5 deg 5.5 mm
+ 10 deg 5.3 mm
+ 15 deg 5.0 mm
+ 30 deg 3.3 mm
+ 45 deg .8 mm
+ 60 deg .3 mm
+ 75 deg .2 mm
Etc...

Cam question

Post by milehial2000 »

Sounds like you have the info. I guess what I am looking for is specs
on a good street cam for the turbo motor and thought that some of the
"hotter" versions of the Legacy motor might give me an idea as I have
heard several opinions on turbo cams. This all started when I spotted
a strange set of rocker arms on the shelf of one of the local yards.
They had rollers and were mechanical non-hyd adjustable arms. The
rollers are more "free hp" about 6 if I am right so I ran home bolted
them on set them at 8 and 10 for starters as adjustment info is not
available started it up and it ran terrible. The roller arm geometry
is different so the timing was off. Supposedly these arms came off of
a '96 engine so I guess I could try the '96 cam but now wonder if a
reground cam might be worthwhile and what the gain might be.

Cam question

Post by Mark Ward »

Be very carefull playing with cams on the motors. I believe there is a
reason not many companies sell cams. Your computer will adjust for the cam.
It would be better to gat a aftermaket computer then get a cam, or even port
and polish or get the roller rockerarms.
If I am wrong, someone correct me...

Cam question

Post by subman2001nz »

I have a company that build cams just down the road from my home,
what they do is build the lobes up to increase the duration, but
still retaining the same amount of lift, rather than machine the base
circle on the lobes, much better because then you don't have to screw
around with valve springs, shims, lifters etc.

The Group A spec for these are 230 degrees duration @ 0.050 for the
EJ20 motor.
