Advice Requested On

[RIFFTOR]

Hey guys, i recently purchased a 1998/9 made R34 N/A with 44,000 on the clock tis a good little car but i feel that it could use some more power especially at the lower revs. I rev it in trip tronic it has little power then all of a sudden around 4,000RPM it has alot of power but then i need to shift before it hits 7000 so i have a very small band of useable power - the rev limit is hard and will not drift into the red zone meaning 7 - 9 thousand RPM are completly useless but something tells me I wouldnt want the car to be running that hard...

Im looking at my options as the car is completly stock but i am trying to achieve a power increase with a minimal reduction on engine life (i want 3-5 years out of the girl) and minimal increase in fuel consumption as this already owns me coming from a 4cyl background a minimal simple power band swap ie. loosing more power at the lower revs but gaining more at the higher engines (im thinking of chipping in this regarding. Also not wanting to increase the noise produced by any greate degree as the sports muffler on the H22A prelude pissed of the neighbours, attracted cops and damaged the interior leaving me with a permanant rattling sound somewhere under the dash that wasnt there prior to installing the exaust system.

Options for the grand or 1 or 2 grand im willing to spend include as far as i know.

Chipping at my friends place "chip talk" at the gold coast to hopefully gain more effort from the engine and tune it to use its power more efficiently

Exaust system again! but hopefully with a quieter exaust this time or just doing the headers or something more conservative

cold air intake professionally done so as to not have sticky tape in my engine bay of my shinny newish car (am considering this)

plenum/throttle bodies etc. to increase fuel consumption at a increase in fuel consumption (not crazy about this option)

port and polish (am considering this)

and any sort of weight reduction such as space saver tyre, skinnier girlfriend etc. (am forced to obtain new girlfriend due to circumstances beyond my control - next girlfriend shall be lighter or at least have a carbon fibre skirt

I should mention i am very wary of simply chipping the car or adding a cold air intake as i hear horror stories from my dad who used to race cars and motorbikes saying that they take away torque from one power band and add power somewhere else, you dont get something for nothing in most cases, you greatly decrease your engine life and most importantly of all

Nissan engineered my car with millions and millions of dollars spent on making it the best - the best for the majority of conditions - but still to be the best for what it is. I am very wary of any exaust company in mount gravatt (pipewerx im thinking of you) could possibly produce beter over all results then nissan however im the one trying to obtain the increase here and i admit it wont happen without modifying my car so i guess i have to make some consessions regarding engine life and fuel consumption etc.

Can anyone suggest the best modifications/upgrades that are tried and tested and worth installing on my pride and joy? Thanks guys (oh i should mention its a 2.5 litre N/A engine i believe its called an RB25 with NEO low emissions classification)
