[Vwdiesel] Fuel line I/D's

[Shawn Wright]

Karl M. reports that 14-15 psi results in a cleaner burn and lower EGTs on his 1.9TD 
AAZ. But his is also intercooled, uses raceware head studs, and a stainless head 
gasket (stock on the 1.9). So whether 14-15 is safe long term on the 1.6TD in stock 
form is uncertain. I would think that the head gasket would be the first thing to go. If 
you are looking for more power, intercooling is probably a safer route - this is what 
the factory did in some Euro spec 1.6TDs that were rated at 80hp. Fitting an I/C in an 
A2 can be a real challenge though!
