non rev-up vs. rev-up

[CPM.06.G35S]

i hear you guys talking about this -

what is the differnce between the to and why?

I have an 06 g35 sedan - what engine do i have?

thanks

if you have the manual transmission you have the rev up motor and if you have the automatic transmission you have the non rev up motor

i think it has something to do with the rev up motor having variable valve timming on the exhaust and intake versus the non rev up haveing valvve timming only on the intake

Okay now its my turn. i have a 04 6MT so ima assumeing its Rev-up or is that only certian year? and what is the difference with the V2 and the factory. I just bought the car and have major plans for it. Just trying to figure a few minor things out first before i dump money on something i dont need

nope dood sorry u hava non-rev up this is how it goes:

03-04 G35 Manual Non-revup

05-07 G35 REV UP

ALL Autos are NON-REVUp excpet iono about the 07 g35 sedans though

To be Clear;

All 05-06 6MT G35's had the rev-up motor.

Only the 07 G35 Coupe 6MT have them as well.

The 07 G35 Sedan has the HR.

None of the 03-04 models have the rev-up.

so what is the big difference...

[kdfja1]

rev up motors have more hp but less tq but if u get a MREV2 for a REV UP motor like me with spacers u'll get the NON-REVUP's TQ and the REVUP's HP , but a little bit extra for both.

[04G356MT]

so if i get a mrevv2 for my non-rev ill still get a bit of gain just not as much as rev-up motor right? what is the difference in the motors? and how much of a difference for HP, sorry if im asking too many questions just trying to get it straight

[boringdrifter]

no please ask away, cuz i would love to know as well....

The biggest differences is the rev-up version has Variable Timing Control on the exhaust cams as well as the intake cams. But unlike the intake VTC, the exhaust VTC uses a 3 step cam phasing where the intake VTC is infinitely variable between it's min and max points. The intake plenum is somewhat different as well. The internals are a little stronger on the Rev-up as it needs to deal with a little bit higher tensile loading created by the higher piston speeds.

While the peak torque is 10 less than the non-rev-up, it makes more than 10 ft-lbs of torque more at their respective peak HP. Even moreso at the rev-up motor's peak RPM vs the non-rev-up at that same RPM. Coupled to the higher revs available and more torque at those RPm's, the rev-up version will lose a little less steam as it approaches redline.

Very Slightly yes Motordyne does a rebate of 125 dollars off of the the price (usssually around 410+) but if u ask me it wouldnt be worth it.

i see i see...makes sense now. But if you were to put a 04 next to a 05 with the same driver how much of a difference do you think you would see in performance wise... not that its important in any shape or form

Not much. The 05+ are a little heavier than the 03-04. At least in the coupes.
