cam specs: 61/61t/67/VR4.. i need em!!!

[lancergsr4g61]

as above i need the specs for the cams below :

NA 4g61
4G61T
NA 4G67
VR4 RS: i already have the spec for these cams, but chuck them up for comparsion sake..

i will soon have a set of each of these cams to go into a 4g61t, and i need to know the specs on all of them to gain the best maximum output with the sets that i have..

i know that u can use the inlet 4g61t cam and the VR4 exhaust, for a good increase, but just seein if there is abetter option...

Cheers

so turbo and n/a share the same exhaust cam.....

 

[lancergsr4g61]

i gues the turb inlet would be milder, to make up for waht little 'lag' there is... wouldnt be much tho..

if anyone has the total duration specs that would be F#$%in sweet!!!!
ideally i wanted some VR4 AMG cams, as they are 260/264 total duration, but i wanna get the best possible combo out of what i got...

as i will have 4 sets of cams soon....

252/252 vr4 4g63 6 bolt turbo

 

[JayRome]

what would be rougher/milder then a N/A cam?

 

[GVR40]

the turbo cams are milder i believe, less duration

 

[JayRome]

i would have thought n/a cams would be an upgrade to the turbo engine....... hurm....

gsr galant
intake valve opens - 26 BTDC
intake valve closes - 46 ABDC
duration - 252

exhaust valve opens - 55 BBDC

[JayRome]
