Losing Power :(

[skyline_freak_r33]

hey guys

a couple of weeks ago my car had a new engine put into it.. it was an rb25det.. the mechanic Adrian at Bitsus Customs had notified me that my turbo whistling may be the gasket which is leaking.. me and my brother have noticed over the last 2 weeks it has dropped in power (more of the kick when the turbo kicks in).. do you guys reckon it would be a gasket or something else?

Also would it cause a major power drop?

cheers

gasket shouldn't cause a noticeable power loss, doesn't mean it couldn't play up on something else things usually snowball

Does it blow black smoke? The whistle could be a small boost leak.

when i first got it just felt heaps gutsy and more punch

nahh

engines only done 100k's

would a gasket leak make a huge power difference which is making me think!!

air escaping sounds like boost leak

check all intercooler pipework

cheers man

i will have a better look at the intercooler piping tomorrow and see what it is

i will let you guys know how it goes

Also check pipes that connect to the plenum as some of them are under boost pressure.

Dom,

As the guys have said, check the pipework for a boost leak. If you've recycled clamps, but they don't look right, ditch them and get new clamps. I've got a set of 3" to 2.5" (or 3" to 2.25"?) reducers in new condition if you need.

The turbo whistling is either the nature of the turbo (induction noise) or a leaking manifold gasket. I have both. One day I'll change my gasket, but until then its not hurting the engine ... only making whistling noises
