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)

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
