    Thread: FSi vs. TSi

    1. 12-23-2012 03:11 AM #1
      Hey guys I might be getting a(n) 07 GLi but my brother (he drives a 10 GTi) he is telling that I should wait an get an 09 which it comes with the TSi.... He is saying that the FSi sucks.... Can you guys help me out?

      Yeah... I understand the FSI is by no means bad, but listen to your brother. And do your research.

      depends what you want.

      FSI has more after market tuning but has a couple quirks that need to be watched.

      TSI has less over all potential but is simpler day to day.

      TSI= timing chain

      FSI= Belt

      research the pros and cons of chain v belt


      and when all the TSI kids get pissed following this, keep in mind that VW switched backed to the FSI for all its new performance models
      Pay now or pay later, either way, you pay.

      If you are in any way mechanically apt, the FSI can be a fantastic engine, you just need to stay on top of it with some preventative maintenance. If you are looking for an engine that you can leave be and not worry much about, try to find a TSI. It's true that the FSI has more potential; they don't even put the K03 turbo on the TSI, but the TSI has updates to problem areas (most notably the cam follower).

      I love my FSI and I'd rather have it than the TSI. GL.
      WTF... I cut it twice and it's still too short...

      For further clarification, the main difference between the two is the fuel injection.

      FSI stands for Fuel Stratified Injection
      TSI stands for Turbo Stratified Injection

      I can't find the specifics but the angle of the injection was changed for the better on the TSI engine. This also improved the fuel management. Emissions improved, PCV was improved, internals were improved, compression lowered a bit, and some other little things.

      As stated, if you are mechanically inclined, the common FSI issues aren't a huge deal and are preventable. Also, FSI motors have one engine code: BPY. When buying parts that makes this makes things easy. TSI has two codes in the US; CCTA and CBFA. The CBFA is a higher emissions version with a breather on the air filter box.

      Regardless, they are both good motors as long as you take care of them. The old saying of "garbage in, garbage out" applies. Treat your TSI like crap and you will have just as many problems as an FSI that is treated like crap.

      I have had my GLI (FSI) since 2009 with 3,000 miles on it and have only had the intake manifold flapper motor go bad (seems like all BPYs had that issue and even some TSIs) and that is it. Minor oil consumption during the Winter, especially if I push the car hard during the colder months, but I have had no complaints.

      I had this happen in mine too. Covered under warranty and it might have a TSB and extended warranty associated with it as well.

      Mine was also covered by warranty. Most dealers should stock the part. It's pretty common.

      Its a recalled part they replace it if it breaks or if the car is in the shop for something else.. theres like 5 things like this on the FSI I had it in there for one of them and they did them all.. but other than that I have never had an issue with my FSI.

      the TSI is VW's answer to all the common problems of the FSI. These things include cam follower, PCV fix, chain driven cams (i think), and revision D diverter valve. do some research on all of these. nearly every FSI driver has had a problem with at least one

      Get the 08.5 or 09 TSI...you won't be disappointed. It's what they put in the new cars!

      Yes the Golf R is an oddball. But they do put the TSI in the new GTI, CC, Tiguan, EOS, and Beetle.

      once more aftermarket fueling solutions present themselves the tsi will be stronger than the fsi. they already make more power with the same hardware w/o an aftermarket hpfp.

      but that will never happen so my post is useless.
      There's a little bit of rice in all of us.

      The FSI in the Golf R is a heavily revised version of the original FSI's. Complete with much stronger internals

      Where did you come up with this? Isn't true at all. TSI makes more power than a FSI at any stage 1-2+ tunes. VW used the S3 motor because it was cheaper to certify than spending millions to have a new motor certified on a limited car they ended up extending production on. And yes it is the 265hp FSI Audi uses. Supposedly has all the quirks worked out as well as improved TSI injection angles and things so TFSI

      not sure if it's along the same lines but i heard the mk7 fuel injection system is revised to minimize carbon buildup

      TSI still has the PCV issues. And my buddy has a '10 GTI with the TSI and he has already replaced the diaphragm DV on his to the piston style. Not sure if they still install old-school diverters on current '13 models, but some TSI engines still do have the diaphragm DV.

      the new golf r motor is basically an fsi in theway that its timing belt driven but it has all tsi internals. the tsi motor doesnt need much to make power because the fuel pump is higher flowing than the fsi ones. the only problems that you really see with the tsi is the intake manifold going bad thats about it
