My NA > turbo was detailed in my long post 1.6 TD in a Dodge Caravan
http://www.vwdiesel.net/forum/index.php?topic=15633.0Approx Costs:
$120 for what was to be a VW TD exhaust manifold with turbo. It turned out to be a 5 banger Audi with a locked up turbo.
$300 for a new GT15 turbo from Prothe
$65 for actual 1.6 TD intake, used
$80 for silicone 90 elbows for the intercooler loop
$30 for rad hoses to make the intake loops
$65 for K&N air filter for a 7L engine - way over kill
$90 for new timing belt & tentioner
$58 for new head gasket & bolts - wish I had done the studs but didn't want to wait for them in the mail
$200 for an FF trans and 1983 TD block that had N/A IP and manifolds.
$40 - Other items, argon gas, aluminum welding rod, cast iron Ni welding rod, TIG welder already owned...
