Turbo AU

[Duffman]

Hay guys I was getting some quotes just out of interest to see how much it costs to get some extra power now what I wanna know is this is a 4x4 shop and if its a good deal.

First; HP gain 20%

Extractors, hiflow cat & mandrel bent 2.5 exhaust $1500
K&N & Cold air induction $700
Unichip & ignition control module $1340
Custom 3" intake (throttle body to air box) $220

total: $3,760

Second; HP gain 50%

fit turbo conversion & compliance $1100
Garrett GT35R ball bearing turbocharger & fitting kit $2,555
Hand made exhaust manifold $600
BOV - plum back $300
Unichip fuel & ignition control $900
hiflow fuel injectors $140
front mount intercooler & plumbing $1600
2.5" mandre bent exhaust & hiflow 2.5 cat inc turbo dump pipe $1000
dyno tune $440
K7N & Turbo intake system $250

total: $9,585

Now the first thing that gets me is prices for general items seem to vary between the two quotes such as the exhaust with a $500 difference.

Are these good packages or should I look else where.

They are to fit an au2 I6 auto.
