Is There A Way To Confirm High Flow Turbo?

[bobert93]

Hey everyone , I bought a r34 last week and the old owner said he was 99% sure that it has a high flowed turbo but before I crank up the boost past 10psi id like to confirm that it has been high flowed.
the spool is very loud and theres abit of lag till about 2500 rpm, but other then the loud spool noise i'm not sure how to tell for sure.

Sorry if its been covered before but I couldn't find anything in search!

Take off the intake and look at the comp wheel. Compare to a google search of a standard comp wheel.

oh simple, thanks ben!

The intake would have been machined, but much more obvious would be the machining on the exhaust side.

Am I right in thinking it hasn't been high flowed ?

That looks like a regular wheel. So I agree not highflowed.

The exgaust wheel is more obvious, but heaps harder to get to than the intake. In take is a quick check, if unsure check exhaustt side.

the inlet still looks thick too, doesn't look machined down at all , so will just assume not a high flow, oh well!

You can't wind up the boost on a highflow if you don't have a tunable ECU anyway. Do you?

[bobert93]

no just a boost T , ecu and high flow are now on the list haha
