I was looking at Cams myself and personally spoke with a rep from BC about purchasing Cams for a Revup motor, His response was that the Revup was only available one year therefore they not making Cams for the Revup. I know the 350Z had it for 2yrs 2005 35th Anniversary edition and in 2006 350Z 6MT.

My jaw dropped to think most manufacturers don't even look into the G35 as a viable market where the Revup motor was available for 3 yrs on the 6MT.

 

good compression! sharif recommended me those cams for my build as well

 

Both GTM and JWT make cams for the RevUp motor.

 

the revup JWT cams are all versions or just a speefic cam? im asking cause i have an option of going/switching to a revup motor for my build. any suggestions?

 

They are specific cams that fit the revup motor. It looks like the S7R, C8R and C9R cams are available for revup motors. Perhaps they have others - you would need to call them.

I believe that GTM has their Stage 1, 2 and 3 cams available for the revup motor as well.

The respective JWT and GTM websites list the specifications for their cams.

 

any thought on going to a revup? suggestions?

 

Don't.

 

I have not looked into that. Would you need a different ECU? Check with Roger, I'll bet he knows. One thing that I have noticed is that right now there are more aftermarket parts available for the DE motor, although some of the parts are interchangable.

 

lol.. tell me how you really feel..lol.. Can u tell me why by chance?

 

I almost crapped myself.

 

Sure...

1. Much more cam choices for the non rev-up, including the BC Stage 2 cams talked about in the OP (which I think are awesome cams that have shown proven performance for a wide range of builds from 500whp to 1,000+whp).
2. Have yet to see a high power rev-up build that put out significantly more power than a comparable non rev-up build.
3. The non rev-up heads have proven themselves to over 1,200whp, therefore I just don't see the need.

 

I would need the wiring harness and the ecu from a revup

 

those are some good points. thank you. i have a complete full long block (revup) at my disposal and wanted to research my options for my build.

 

The one plus for the revup is that you can play with the timing on both the intake and exhaust cams if you have an EMS that can control them.

 

that def one of the reasons i was looking to make the switch.

 

nice numbers!

 

If I were going to replace the wiring harness and ecu, by that point I would look into whether an HR motor is an option. It's already much stouter than the stock DE motors (both revup and non-revup), and I think can be punched out to 4.2L without sleeving.

I have not yet looked into it, so I don't know whether changing to the HR motor is significantly more complicated than chaninging to a revup motor. Sam recently did one on a 350Z, so he will know the specifics.

 

But aren't the HR greddy kit and the DE kit different? I honeslty have no clue! Stock for stock I know its better than my DE, but built does it make a difference? The DE is more than capable of making power I won't be able to use anyways so I couldn't justify the cost of just saying I have an HR when the power is same as what I wanted out of the DE.

 

Yes, you're correct. I forgot that you already had the turbos. So the HR is out of the question.

There would be advantages to being able to control timing on both the intake and exhaust cams, instead of just the intake cams as on the non-revup motor.

In a revup motor, since both the intake and exhaust cams can be controlled, you will have less valve overlap when the cams advance, which will be advantagous at certain rpms (I'm guessing more torque in the 2k - 3k rpm range). Also, you would have better control for fine tuning the valve overlap at the higher rpms, etc.

What I don't know is how significant these advantages will be, or whether the difference is worth changing out the ECU and wiring harness. Hopefully we can get one of the tuners/builders to chime in on this.

 

Just to clear a few things up, Toms car has 54 mm turbos, Vitos has 55mm Billet turbos. Toms car made 534 RWHP at 19 psi and Vito's made 621 at 18.3 psi. So the only difference is not just the cams.
