Hi
I know were ther is a New GT42R Garrett Turbo for sale.
Info i have on it is.
Compressor is .66A/R
Hot side .91A/R

Ported Shroud

Will this be any good on a 20B
Engine will not be ported.

Thanks

it'll be killer on the low end with a hot side that small. . .

might run out of breath up top though. . .

mine's a 1.0 on the hot side, so it's not a whole lot bigger. i'll be posting up as soon as i get everything in place and let you know how it feels.

if the price is right and the condition is good, you could always sell it if you don't like how it feels.

if i was you, i'd ask Zero R what he thinks about it, i'm sure someone smarter than me will chime in here too though

good luck

How would the low end compare with a Hybred ( stock turbine s5, t04b/h-trim compressor) on a 13B Re that dyno'd out at 306 whp?

That hot side is kinda small. I have the 1.15A/R on my 13B so the .91A/R might be too small for a 20B. But I dont have any experience with a 20B so I would ask Sean at Aspec (ZeroR).

PDViper77,

what's the response like with your setup? what boost by what RPM? what's the altitude where you're at?

mind giving a little info on the rest of your setup

exhaust manifold runner diameter
exhaust system
wastegate size
wheel sizes
coldside A/R
rough IC size
piping length and diameter

i'm trying to gauge what kind of response i should be expecting.

thanks a bunch
