No Hi-flow

[R31Nismoid]

If your 'mechanic' gave you that advice

go somewhere else immediately.

he clearly has no knowledge, or any idea what he is doing/talking about. I wouldnt trust someone with my car thats giving that kind of monkey advice out

=]

For the lack of kick, are you sure it's a boost leak?

If it were leaking, it'd be chewing through the fuel.

Your VCT may have become disabled some how (Bad electrics/plug off)

My car at the moment, doesn't have VCT turning on until 2250 RPM, and you can really, REALLY feel it kick in, and when you watch the boost guage, as it kicks in, boost climbs dramatically (When cruising, it'll sit at atmospheric, as soon as the VCT closes it'll jump to 2 - 3PSi or there abouts.

what was the manifold to turbo gasket like? I had same probs as you with stock turbo and over time it got less and less kick. I upgraded to a garret and when i took the stocker off i found that the gasket was blown out.

Other issues could be timing, cooler pipe leaks, dirty air filter, plugs/misfire issue etc etc lits goes on

It might be the manifold>turbo gasket, not sure really. I think it was replaced by the really smart mechanic. He also mentioned 'timing' needed to be redone cause of the lack of punch AND a slightly lumpy idle.

Thanks for the tips. I'll look into it.

I know you seem to have moved on from the High Flow claim....but for future reference...this is what everyone was looking for

You mean NVCS or whatever it's called? Would have no idea if that's the issue! Can't feel any kick, but i remember how it used to kick. Boy it went hard on stock boost . I miss those days...

Is there a way to check if that's the problem?

Looks like a MONSTER Turbo to me, should make 260 Killer Wasps at the engine LOL

Bummer eh went from a high to a low there mate

[mesmerized]

i still don't get what everyone is looking at , is someone able to photochop/highlight what i'm supposed to be looking at to make it really obvious. i didn't find the gcg link very helpful as the standard turbo in that pic is filthy and taken from far away

[TTT]

look at the turbo's front on.

The GCG hiflow one has a larger entry hole (thinner matterial as it has been bored out)

and the back.

Look how much bigger the wheel is on the back.

an to do this, it has to be bored out.

You will see that the gap between the wheel and the wastegate flap is less in the hiflow pic.

essentially, to make it FLOW MORE as in a HIGHER FLOWING unit, it is bored (machined) out to make the holes bigger.

Then they use larger wheels to fit in that gap.
