      Just curious, as I think I'll be back in the market for a summer-only super clean 12v or 24v vr6. I will be making it fast, so I'd like to know which one is the most receptive to mods and which one gets the best mileage when babying it. I'm going to assume the 24v takes the cake, being it has twice the valves and one extra gear to use... but I'm not positive. thanks all!

      it really comes down to money. and how much you are willing to part with .

      hogwash my friend.. this place needs some technical questions once in a while! But thanks for your input. Was I correct in my reasoning being it's got 12 extra valves and an extra gear?

      I had a 12v that was a blast! But if a 24v can do it better, I wont say no.


      What kind of numbers do n.a. 24v's put down with say cams, chip, exhaust, dp, intake, and some p&p work?

      basically it comes down to how much you want to spend.

      it'll cost less to get a 12v to 400whp than it will a 24v. other than that its the same exact car/interior. 12v does have a better exhaust note. but once your boosted it wont matter.

      As much as I'd love a vrt... I just dont think I'll be going down this path if I buy a vr6. I'll just buy a super clean GTI and do basic motor/suspension mods I think.

      Why is it pricier to build up a 24v? Are parts pricier?

      I'm really enticed by the 6spd in the 24v... but I didn't know there was a sound difference between the 12v's and 24v's.


      How much power can a bolt-on 12v and 24v put down? My built mk3 12v (motor.. trans.. .suspension) would walk many a v8 cars... what will it take to make a 24v faster?

      my friends 24v with Cams, 2.5" Cat back, cold air and, a custom (swap flash) UM flash is putting down 238whp...
      the UM falsh is not the normal one you can buy everywhere else. its a custom one Jeff has done for him...

      And what kind of torque numbers was he putting down? Any idea of track slips or race-kills or something to give me a rough idea of how fast it is?

      think Building a 24v will be close to double the price... look @ a clutch kit for an 02M with lighter flywheel is around $700-900.. when a Whole 02J set up is what $500-600...
      then cams, not sure what the 12v cams go for.. but the 24v's are close to 1k!!

      as far as exhaust or anything else its all the same... think just those few parts are what get you...
      then the cost of maintenance is significantly more...

      Fux. So building a 24v is NOT goign to be cheap in other words.



      is there a weight difference between 24v and 12v GTI's that could offset any performance increases between the 2?

      I will have to ask him what his torque was...
      its fast.. lol 3rd gear pulls feel like a super charger is in the car...

      he Had Jeff @ UM tune this thing up and did some dyno pulls @ his shop...

      no track slips.. he is not a quarter mile guy. lol

      I'm very curious to know torque! Has he raced anything with his modded car?

      theres just some giving things that make it more money.. but IMO its well worth it..

      I feel the 24v has a smoother power range then a 12V... 12v can sound nasty, when a 24v will me a little more modest sounding and feeling...

      24v with the 02m will be a tad heavier.. Ill have to ask my nephew the weight of his 12v and then I could give you an idea.. off the top of my head not sure the weight of the 24V, ill run outside in a minute and check that out..

      I am too now... not sure if he has... we are old so we just do this for our enjoyment not for light to light fun!

      the car is just plain nuts now... that is the best way I can describe it!

      I do love the soudn of 12v's when they are near the upper rpm range.. they sound like r32's and have that amazing sound when winding out. Will a 24v still sound like that? Or will a 24v sound closer to the mellow but nasty exhaust of an r32?

      Ya I hear that. I like a good street race once in a while, but I mainly want another vr6 for cruising and carving the hills/backroads by some families houses.

      I know my 24v is pretty quite... lol my nephew and I both have Megan racing exhaust without the resonators on them and mine sounds very deep and calm.. while his sounds a little more high pitched and toned odd... like you said nasty! lol
      his drones a ton more then mine does but nothing unbearable...

      I hear you with some good street racing once in a while.. someone in a Honda always has to pull up next to you with there coffee cans rattling!!

      I drowed my intake under a puddle a few weeks ago in the tropical storm after the hurricane..
      thank god alls I did was choke out the MAF and the car went into Limp Mode...
      it died instantly.. but after a few minutes she was up and running but suttering away....

      cleared stored codes and was lucky enough to drive on... now car is 100% fine!!
