Tomei Adj Intake Gear On Rb25, Why Wont It Fit?

[muaythailuke]

Hi,

After rebuilding my engine and putting new cams in it etc... ive put adj cam gears on the exhaust and intake.

Exhaust was fine, fit fine and dandy but intake not going on so easy.. why? It doesnt sit centre and its just a sloppy fit the single bolt that holds it in place is was too long..... nothing seems to fit or even look like fitting.

What have I done wrong?

Or have I got the wrong cam for the gear? as in, do I have to buy a cam that not used with the vvt?

Cheers.

thats what it needs buy the look of it. So did you get the collor to fit it to your rb25?

No cam gears for VVT intake cam on RB25s only the exhaust but the factory VVT intake gear is ajustable anyway from behind the gear.

So why do they make an intake gear for an rb25 then? Or do you have to buy a different cam to use it?

[FATGTS-R]

Because the cam gears are not RB25 specific. They can be used on an RB20 for instance.

without sounding like Nismoid for a second.....

do a search .....

I think you can use the RB20 cam of a similar spec and adjust it that way.

Yes you can use an RB20 intake cam but you lose the VVT.

[muaythailuke]

So if a buy an aftermaket RB20 cam of the same spec it wil work no worries in my head? Cool!

But now after taking the vvt off I noticed that there is some adjustment in the back of the gear itself, maybe not be enough but if a take it to an engineering workshop I should be able to get some more adjustment out of it. That way a cam keep the vvt, that would work right?

[N I B]

The VVT gear has plenty of adjustment for most setups.

RB20 cams are a simple fit into RB25s.

yeah there is a fair bit of adjusyment in it but when I took it off it was already hard one way and im pretty sure I have to go a bit further that way
