[Vwdiesel] turbo on NA engine

[Terry Briggs]

As much as I'd like to convert my na golf, I think I'll wait until I 
find an old td in the bone yard and yank the engine out of it and 
rebuild it. I have a moderate amount of miles on it at around 240k and 
I do get good results with it. I rebuild engines in my garage a couple 
times a year, so it's no big deal to rebuild one, though I've never 
rebuilt a turbo before. I just like all the info I can get. All I had 
to go on was what I read about, Mainly because the gassers do it all 
the time, but they aren't working with the same head temps as a diesel, 
at least I don't think so. For now, I'll stick with a larger exhaust, 
more effiecient air intake system, you must admit, the stock air intake 
on an na diesel is very poor at best, I almost laugh when I think about 
it. Thanks for the advice, all info is good info
