ae824ate Posted February 20, 2011 Report Share Posted February 20, 2011 Weber (or whatever carby tickles you), extractors, exhaust, cam if you can afford to, all the simple things. Depends how much money you want to spend. Do a little research, itll get you a long way. Most NA motors will benifit from the same modifications.

RainWarriorDregs Posted February 20, 2011 Report Share Posted February 20, 2011 You know that all car modifications are illegal on your p's? double check on your states transport site, but i'm pretty sure. Quote Link to comment Share on other sites More sharing options...
philbey Posted February 20, 2011 Report Share Posted February 20, 2011 This is the overview of mods that are not allowed for P Plate drivers:  Their examples include Extractors and Camshafts  From this page  Vehicle modifications to increase engine performance  The following information is provided to help determine what constitutes vehicles modified to increase engine performance as defined under the high powered vehicle restrictions for P1 and P2 licence holders aged under the age of 25.  This information is provided as a guide only. It may not be exhaustive and should not be taken as a precise interpretation of the law.  Vehicle attributes that are affected by the definition of vehicles modified to increase engine performance include:  * Induction system * Fuel system * Engine * Exhaust system  Note: under no circumstances should any of the above be modified or replaced with parts or components unapproved by the vehicle manufacturer, unless it is deemed essential during routine maintenance or failure rectification, see examples below:  Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted February 20, 2011 Report Share Posted February 20, 2011 (edited) Yeah, but I'm sure this makes it all non-applicable!!  the high powered vehicle restrictions  :laff:   Do the same as I've done- The usual stuff, so it keeps up with the trafffic and cruises at 100kph without a problem.  http://www.rollaclub.com/board/topic/42407-the-girls-ke70/page__p__445727__fromsearch__1#entry445727 Edited February 20, 2011 by altezzaclub Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted February 20, 2011 Report Share Posted February 20, 2011 (edited) Ah- those restrictions are only for people who have only just GOT their P-Plates. Sept 2010.  High-powered vehicle restrictions If you obtained a P1 provisional licence on or after 4 September 2010 you must not drive a high-powered vehicle if you are under the age of 25 until you get a full drivers licence. That means:  *vehicles with engines of eight or more cylinders *vehicles with turbocharged or supercharged engines (excluding diesel powered vehicles) *vehicles that have been modified to increase engine performance *nominated high performance vehicles, including BMW M & M3, Honda NSX, Nissan 350Z & 370Z, all post 1994 Porsches and the Mercedes Benz SLK350.  View the list of excluded vehicles (PDF 65Kb) including those vehicles where manufacturers have used turbo charged or supercharged engines for fuel efficiency improvements, but are not classified as high performance vehicles.  If you are caught driving a high-powered vehicle, a $250 fine plus 3 demerit points applies, but could be as much as $1,250 if you go to court. High-powered vehicle restrictions do not apply:  *when you turn 25 years of age. *if you had your P1 or P2 licence before 4 September 2010 Edited February 20, 2011 by altezzaclub Quote Link to comment Share on other sites More sharing options...

Twinky Posted February 21, 2011 Report Share Posted February 21, 2011 If you can find a 5k that would be the best option. Visually it does not look any different to a 4k (not to the untrained eye) and it gives you a nice amount of torque. Any roadside defect station will not be able to pick up on it as it is identical to the 4k. BUT if they were to actually read the engine stamp you might not get away with it. But in saying that the motor does not even need engineering because it really does not make mutch more power than a 4k, just that it is more smooth in power delivery and driveability.

altezzaclub Posted February 21, 2011 Report Share Posted February 21, 2011 Weber, cam and quiet exhaust. & a 5speed! Â The Weber looks enough like the stock carb, the cam doesn't want to be more than 270deg, and if you keep the exhaust quiet no-one will notice it. Â Best way to fail... matt black, or more than one colour, chopped springs, wide wheels, no bumpers, 2" exhaust and cannon, no air filter for wild induction noise... and drive it like you stole it! :laff: Quote Link to comment Share on other sites More sharing options...
