$20K for a 2009? Better off buying a 2010. I paid $14K for my 2008.5 with 28K on the ODOM. Granted, it was a private seller and I had to fly to Baltimore to get it, but nevertheless it was worth the price.
As for the TSI engine, you'll find that Golfmkv is almost purely an FSI forum. Since the TSI builds didnt started until April or May 2008, very very few have the TSI on the MKV platform. If you're looking for stuff other than power train, golfmkv is where its at, otherwise, bounce on over to golfmk6.com for powertrain upgrades, we have quite the list of TSI mods.
As for the TSI engine here are a few differences across the platform. Bear in mind, its the same PQ35 floor comp unit and bulkhead as the FSI, but an entirely different drivetrain:
- Revamped Engine: Internals, fueling system, timing chain, intake manifold, etc. etc.
- IHI VTR501 turbo instead of the Borg Warner KKK-K03 compressor in the FSI. IHI Provides more midrange power, but falls on its face quicker than the K03.
- Despite what has been said, the PCV system is actually quite robust, however, there is an oil starvation issue when tracking these motors. Still, it does not guzzle the amount of oil that the FSI does. I have stretched some serious limits on the street with my K04 and I still have not experienced the issue.
- The TSI 6MT clutch is weak as balls....Stage 1 levels are ok for it, but beyond that, you're looking to upgrade the plate at least.
- The TSI motor is lighter than the FSI, so new springs were redesigned for the suspension bringing the overall ride height closer to Euro spec rather than the original DOT U.S spec. I personally have MK6 Driver Gear springs to bring that spec even closer.
- The fueling system in this engine is BEAST. No HPFP on into the GT28 power levels. Injectors must be upgraded by GT30 Big Turbo levels, but no fuel pump development yet to get huge numbers off the TSI platform.
- As mentioned some TSI's came with the REV G diaphragm DV valve. Upgrade to the REV D or REV C piston type.
- Oil changes are beyond easy with this motor since the oil filter is located on top of the motor. Take roughly 15mins now.
- Two engine codes, CBFA and CCTA. Pray you get a CCTA because the CBFA can get bothersome and mal-tempered. Nothing that a little extra attention cant do, but having the SAI pump and the 02 sensor on the turbo itself get's tiresome when modifying.
