Compressor Inlet Size - Need A Bit Of Explanation?

[-33-]

Well after a LOT of looking around at the options, i'm looking at a GT3071R with a 0.63 housing.

The last choice left to make is the compressor inlet size which comes in 4" or 2.5". Why? What possible differences does this make? (If the answer is NOTHING sorry for asking... but i gotta know!)

I believe the larger snout and associated trunking would just give the impeller a better quantity of air to "grab". Probably a bit of potential for increased flow and power. Not much, but a bit.

Be sure to get the correct spec with the larger 60mm turbine. I understand skylinecouple is very happy with his results.

Hopefully you can update this thread with impressions on the delivery yours provides after tuning.

yeh that makes sense.

And yes, i will get the correct spec 3071. Ive already got in touch with horsepowerinabox, they can do a complete kit with the proper garret .63 housing, including all lines for $2050. Got a mate who has contacts in Honeywell however... might see what he can do

Throw in my PFC, injectors, fuel pump... and everyones happy =D

Il definitely let everyone know the feel of the turbo; its reputation is definitely growing as an alternative to the GT-RS and similar turbos (and at a cheaper price).

Thanks for the help =)
