Turbo oil lines 3b with AC

[Joakim_s2]

what is the best option to do with the oil and cooling lines on a 3b with AC ? Going to run a 30-660 turbo

I've just had to check what a 30-660 turbo is, that should make for a very fast spooling turbo on an S2 as it's only GT25 size.

I'd imagine being a modern Garret that the oil feed-line requires a pressure restrictor unless Garret are building them into the core of the turbo now, I didn't have time to to go through the full specs and installment instructions.

You're almost certainly going to have to get custom feed-lines made to suit the application, unless you're very lucky and the Garret core inlets ends up positioned and orientated close enough to the original KKK K24 inlets to use adapters. This is very unlikely.

The return lines are generally a little easier to adapt for non KKK turbos but again it very much depend's where the outlets on the Garret are compared to stock.

Garret should tell you what diameters etc are required in their installation instructions.

What exhaust manifold are you using?
