just wondering, seems to me the major thing is they are newer and easier to find in good shape.
but in terms of performance, are we looking at any gains? i found a nice rebuilt shortblock, just wondering what i should do for a head
lowers compression and way way way better intake ports. and some have 7mm valve stems
Lower compression may make for harder winter starts, but will be more efficient. If you use the 1.9 head you need to get a 1.9 or TDI intake manifold as the port shape is different than the 1.6.
I don't think you need to, but it would definitely be a good idea. Especially if you are running more then stock boost.
Yup it's a performance thing, it would be useless if running NA and would be harder to start to boot.
Running TD you'll get more power with less boost, compared to a 1.6 head.
cool, i plan on having a custom intake manifold made, and some porting and polishing. so this is good info.
there are already a couple o guys on here who have done it and are currently doing it "talking about myself" I have hit a financial blockade currently and can't continue for a while, but you can be sure that I will finish. I wish you the best of luck on this, most illustious of builds.
stay excellent
