richcoad89 Posted August 17, 2011 Share Posted August 17, 2011 Hello all, I've been reading alot into performance mods for my 350z. I can't afford a vortech v-2 or a cosworth plenum, but I'd like to round the power up to around the 300bhp mark. The section about mods here is brilliant and I have learnt alot from it, but on a budget where do I start? Oh and here's the thing - I don't really want to change the noise it makes too much.... I was thinking headers, y-pipe/decat, 06 onwards airbox with high flow panel filter, plenum spacer and a remap to top them all off?? Can anyone add some experience to add or change what you think may be better. Also I need things to be fairly easy to do, I have access to tools and a ramp but can't rip the engine out for a stroker kit! Thanks!

rtbiscuit Posted August 17, 2011 Share Posted August 17, 2011 if your sticking NA 300 is do'able but imho your better to put the money FI, the amount you end up spending to get to 300 you only need a bit more to go FI. but if this is your chosen route then this would be my list Plenum spacer decats motordyne XYZ pipe with straight pipe. (has an interchangable cat for MOT) decent exhaust 06+ airbox decent panel filter remap from someone like RStuning, abbey, or horsham Quote Link to comment Share on other sites More sharing options...
introspect Posted August 17, 2011 Share Posted August 17, 2011 Headers will be very costly to have installed (anywhere from 8 - 12 hours labour) so unless you can do it yourself I'd leave them. Plenum spacer, de-cats, a Motordyne XYZ pipe fitted with a race cat, post 06 air box and finally an Uprev tune will give you a decent boost in performance. Might also want to consider the AMS light weight pulleys to help the car rev more freely. Don't bother replacing the mid pipe or the exhaust back box as that will only add noise and not give you any more power. Quote Link to comment Share on other sites More sharing options...

The rest of the exhaust system apparently flows perfectly well. Quote Link to comment Share on other sites More sharing options...
richcoad89 Posted August 17, 2011 Author Share Posted August 17, 2011 Thanks for all the advise guys! I don't mind a change in tone (as long as it's a nice one) it's just I drove a full hks system 350 which was just a little too loud for everyday driving! Yea FI would be good but mines a slightly high miler at 84k so i presume an engine rebuild would be on the cards for that! Could I ask a noob question?? What's the revup mod? I'd love to think that the latest 350z models (the 313bhp ones) were just an air box upgrade or something!! wishful thinking! Quote Link to comment Share on other sites More sharing options...

Adam@Z1auto.com Posted August 17, 2011 Share Posted August 17, 2011 first thing you really need to do is establish whether that desired power is at the wheels or crank next, is setting a budget for yourself to accomplish the desired goal third, what year is the car?
