that would depend on what car it is in. i get 8l/100km (mixed highway/city) with my 4agte (stock smallport w/ GZE injectors & 2540 turbs, haltech ecu) setup in the ke20.
they would be heaps of small things to get little bit of power, but on their own would they be noticable? and if you did a couple of things, would it be worth the cost?
don't bother spending money on cams and headwork and exhaust for your motor. just love the good fuel economy you get from it.
save your money and buy a car which already has the power you want, or be prepared to spend 'an awful lot' to get decent results.

yeah, its so bodgy. i reckon you could get a hacksaw out and make it shorter. its just that we shouldn't have to, whats so frustrating is that the pic on the Techno Toy Tuning website shows an obviously different strut brace, why they sent these shit ones over is beyond me. i wanted the one on their website because it lifts the actual bar up an inch which is all i need to clear the inlet manifold. i got no reply email when i complained.
i was using up what i had left over, i wrapped up the starter motor with it.
looks fair ghetto in full view around the air filter, but will probably change it one day.
no the original tare weight is what makes a conversion legal.
the normal process for 'legalising' your modified car is:
consult engineer
do mods
get engineers report
get new weighbridge certificate
get blue slip (not the full on blue slip, but the form is still blue and the mechanic needs a blue slip licence)
get brown slip
take to RTA and they use the brown slip to:
1. update their records so your registration renewal form will show the new engine number and new weight
2. print you a new rego sticker which will have a special line showing a number which references the copies of your engineers report that the RTA now have on file
basically you can't mod a car, get a report and then think everything is ok. in NSW you must let the RTA know and let them change their data they have on your car to make it legal.
cheers mate,
i started on a simple fix, closing off the pod filter with some of this stuff today:

there are heaps of cars around that were engineered before the rules became stricter - that is why you might see some cars with seemingly impossible conversions.
to determine whether a conversion idea is possible they use the factory weight.
you need a weighbridge certificate after the conversion to go with the Brown Slip (together with the engineers report and blue slip) for the RTA to update their records.
i.e my new tare weight on the rego papers is 860kg, but the factory weight was 760kg.
Its a pro job - tig welded steampipe turbo manifold, 2.5" mandrel system with high flow cat, resonator and straight through muffler - really quiet.
