High Flowing Turbo?

[Bambill]

You really need to stay away from the so called high flowed turbos.
Either machining housings for a different CHRA or whatever.
The standard compressor housing is not large enough to cope with increased compressor flow. The turbine housing is not so bad, and croping of the turbine wheel can help but at the expense of response.

United do sell a good setup, but the Garretts are cheap.
With the dollars the way it is you can buy all you need to swap to a Garrett for less than $2k.
Not sure of the price of the United setups but they are a little dearer.
I have no preferance either way it just comes down to dollars which way you go.
Either will take about a day to fit if you are handy with some spanners.

A simple turbo change such as this, setup to run the same or even slightly higher boost would also be perfectly safe to drive without playing with other things.
Simply bolting either of the turbo's mentioned on will not create higher EGT's unless something is drastically wrong.


As for the comment that the Garretts are know for high EGT's, why do you say this?
They may not be ideal but.
I use the same GT28 turbine with a .64a/r T2 housing at a drive pressure of 1.3:1 on 30psi and have no EGT's issues.
If I'm lucky I might see 11-1200degF pre turbo.
I have held it at 3900rpm in 5th with a 285 tyre for upto 2km with egt's steady at 1120degF pre turbo.
Admittedly this is not a standard setup but it shows that the high EGT thing is a little bit of BS.
