To Hi-flo Or Not To Hi-flo, That Is The Question

[discopotato03]

If you're std turbo is in good nick you could fit the VG30/R34 RB25 Neo exhaust housing . Goes bolt to all std fittings and looks standard too , the trick is finding the housing .

A few of my mates went to these guys (http://www.per4manz.com) to get their hiflow and rebuilds done. They told me they got a hiflow job for about $1300-1500 depending on bearings. They used garret 500hp steel wheels as well. Seems like a pretty good price to me and they havnt had any issues with them.

The rebuilds were around the 500 mark, but that was a while ago and this is only word of mouth, i havnt got quoted from them.

This is an exert from a recent email:

The upgraded turbo that we build for the GTS-t runs a sleeve bearing not ball bearing. I much prefer to build them this way because it takes a lot of the harmonic frequencies out of the shaft and as long as you do regular oil changes they will last as long as a ball bearing unit.

We use a stage 3 turbine wheel and a 400hp high flow compressor wheel. Both are Innovative units . Spool up is fantastic and they make 320-340hp at the wheels at 15 psi on most cars that have had them fitted. We modify your existing turbo and require this to be sent to us. Cost is $1400 including a new oil feed line and fittings.

Thats interesting. I wonder how long they would actually last...Probably have to cool down more than with ball bearing turbos right?

If it was a bit cheaper might be worth the risk...
