New engine, old turbo?

dejavecu · 10-03-2009, 09:31 PM

So I am getting my shortblock replaced, should I wait on installing a more powerful turbo, larger injectors et cetera. Should I keep PSI low till the engine breaks in?

Might as well get it all on why it's apart and keep boost low for break in period

You might as well throw on the larger turbo with the SB since the larger will be easier to keep out of boost for a safer break-in period.

When I say I am getting it replaced, I mean the dealer is doing it free of charge. I know they must be capable (let's be honest if they can't do this they should not be putting the engine altogether) but I feel this will open a can of worms having them put all of this on. If they do not do a good job on the install, I can see them pointing the finger at the aftermarket parts.

i had my shortblock replaced under warranty from a dealer, and i had a VF39 + supporting mods on when i came in, and there weren't any problems for them to put it back on (naturally since it's a VF series), and i had no issues during break in. just follow standard break-in procedure of course, and don't boost high until it's broken in. i don't think they will be too willing if you go with a non-subaru turbo, though. what are you looking to run?

unless the turbo is a rotated setup, there shouldn't be any problems having the dealer service doing it, except of course on the issue of tuning, which you will need to do with a new turbo anyway. if you're going custom turbo or one without an OTS cobb map that you can run on until you break in (VF39, VF34) then you might want to hold off.

BTW turbo installs are not all that difficult if you have the time and space

except the injectors of course... ugh.

It is a non-subaru turbo; Blouch 16 evo III.

as long as its a stock location turbo, there shouldn't be any technical difficulties in installing it at the dealer. Tuning, and whether they want to touch an "aftermarket modification" however, is up to them.
