ok as in straight fit, no modifications?

How much will a remap cost, and does the extra power affect mpg greatly?

Mpg will be near enough the same. map will cost £200-300 and its a straight fit as the only differences with the 150-130 is the turbo, FMIC and map

@ Steve/Rhyso - Do you know how much bigger? I assume the exducer and inducer (correct names?) are different sizes? The 150 is a vnt17/22 right?

The turbo is the same size, it is just the internalls that are up-rated IIRC - the materials used are to a higher spec to withstand more boost and the compressor wheel may be larger.

You won't need a remap unless you wan't extra power as it will run the same as your 130 unit :afro:

Turbo for a 130 = GT1749VA
Turbo for a 150 = GT1749VB

The specs are:

VA:- 35 mm intake and 36,5 mm flight

VB:- 37 mm intake and 38,3 mm flight

The VA model off the 130 will have a faster spool up, the only problem is the intake wheel is not meant to go over a set psi range while the VB is designed to support higher boost levels
