Cams?

[GTS4WD]

Hay guys,

Im interested in getting a set of cams.. But i dont like putting things in my car if I dont fully understand how and what they will do. So I have a few questions (mechanical explinationes prefered)

What are the complications with getting exhaust and inlet aftermarket cams in a CVT 25DE?

What size's/lift/duration are best for street driving? Anything to enhance Mid AND high range?

How much power will gain with a good tune?

What prices am I looking at for a good set of cams?

Is it worth going overkill and getting massive cams? What are the differences in cams? E.i How and what happens if you increase left/duration?

How do I tell the left/duration?

Will I have to get cam gears?

At what point will I need to go larger injectors?

Thanks in advance guys!

Will have a go at some answers...

What are the complications with getting exhaust and inlet aftermarket cams in a CVT 25DE?

Um, like....?

What size's/lift/duration are best for street driving? Anything to enhance Mid AND high range?

With regard to this motor, not sure.

How much power will gain with a good tune?

Depends on the cam & any other components fitted.

What prices am I looking at for a good set of cams?

About $1k for two. Sometimes more.

Is it worth going overkill and getting massive cams?

No. This will simply remove low & mid range torque & you wont be able to pick up any top end hp.

What are the differences in cams? E.i How and what happens if you increase left/duration?

Lift (not left) is simply the amount by which the cam lifts the inlet and or exhaust valve away from the head. Duration is the length of time (in degrees) that the cam does this for. More duration valve is open longer, more lift valve is open further.

How do I tell the left/duration?

It will be stated by the manufacturer.

Will I have to get cam gears?

Not necessarily.

At what point will I need to go larger injectors?

When you run out of injector flow. Broadly every cc/min in a 6 cylinder equates to a rwhp.
