      MK3 GTi VR6 Drivers Edition
      11-20-2019 10:07 AM #1
      Hello Folks, I have a bone stock mk3 vr6 and I'm trying to achieve somewhere near 185-200 hp, N/A.
      So far I have:
      -1.8 IAT sensor (Noticed the difference)
      -All engine and tranny mounts are BFI Solid.
      -Drivetrain bushings replaced with Prothane.
      -LSD on a stock tranny.
      What I have in mind is this:
      -Schricks 268 Cams.
      -Supertech Valve springs and retainers.
      -ECS tunning LW Pulleys
      -LW Flywheel.
      -2.9 clone Manifold.
      -Light port and polish on the head as well as intake/exhaust manifold by a professional.
      -TT Chip.
      -MK4 Metal HG
      -Still have the OEM Airbox, not sure if I should modify it or get a cone filter or something.
      -Test pipe and 2.5 complete muffler system.

      My question is this:
      Would that accomplish my goal?
      What is your suggestion?
      Thank you.

      I made low 180s at the tire with a similar setup but 262 and stock head.

      Any recommendations on the intake?
      I just don't want to plug a cone filter and call it a day.
      Is it okay to drill holes or make a big hole on the bottom of the airbox?

      Something like the Autotech or Turn2 have worked best for me.

      I am not sure Need_A_VR6 asked but do you have an OBD1 or OBD2? If you have an OBD1 to get a bit more air flow and better throttle response have your throttle body ported to the Euro 2.9TB size b/c that bump in the U.S. TB just messes some stuff up. When you get your 2.9L Intake Manifold makes sure the neck where the TB hooks up to your Manifold is also ported as well. If I am correct(Paul Correct me if I am wrong)when people get cloned 2.9L intake manifolds they don't see much gain b/c the neck is largely ignored. Some inexpensive mods you can do relatively easily is port and gasket match your exhaust manifold and lower intake manifold as well. I would also do mild to race motor/tranny mounts as well, but this is dependent on how serious your are with your build. Autotech262's are great Shrick 268's are expensive and net a bit more power up top. When I had my MKIII VR6 Jetta I was lucky enough to get DRC268's. I liked the DRC268's b/c they gave almost as much if not the same power as Schrick 268's but were $400 to $500 less at the time than Schrick 268's. It has been so long since I've been in the game that I have no idea if John Doherty is even in the car business anymore. If you can pick up a cheap and working pair of DRC268's I highly suggest them if not Autotech 262s will work. One of the biggest day and night mods I have ever done(it doesn't give you power but changes the power band)is when I put a 3.94 Final Drive into my VR6. I am not sure things have changed or new information has been learned about The 12v VR6 but the VR6 head is where all the problems are b/c of it low ability to flow air. Head work is the key. Proper Head work for that matter. So be careful who you have work on your head and make sure they have had experience/positive results with P&P'ing The VR6 head. Good luck and if you can get a Turn2 CAI go for it b/c they are probably hands down the best but went out of business a long time ago. When it comes to chips I am not even sure who is in the business anymore. Is GIAC even around anymore? Is United Motorsports still around? Hmmm Well as for exhaust go with a Techtonics b/c they are reliable and probably the best one out there for your level of modding. With what you plan on when it comes to your mods 185 should be easily attained now 200whp is not so easy or cheap for that matter. If our 12v VR6 heads flowed like a B16,B18, or K20 life for N/A VR6's would be much nicer but we wouldn't get that VR6 Wookie Growl either.

      Wow, thanks for the reply.
      Very helpful one.
      Regarding the Schricks i got them from a friend, they were used lightly. and they cost me the same as a DRC set.
      Also got from him a Bully Clutch.
      My Car is OBD2.
      Ill try porting my TB and the Intake neck, same with gasket matching the exhaust side and the intake lower portion.
      Already have Engine/Tranny Mounts from BFI solids. as well as an LSD Peloquin.

      Regarding the 3.94 final drive ratio, the only thing i need is the 3.94 'Crown'? or i need the pinion changed as well?

      Do not port an obd2 tb with a stock ecu it will buck like crazy.

      For 3.94 you need both the ring and pinion gears and a quite thorough transmission disassembly.

      What do you guys think of the TT downpipe piece?
      Have you seen any gains with it?
