Cam gears by themselves do nothing. Cam gears are only needed if you have aftermarket cams, and then only if the standard cam gears don't offer enough adjustability.

cam gears can be used with stock cams to move the power band around, particually for na when you want to increase the overlap to get more top end out of the cams. but there's better options to spend money on to get more, for example getting your cams ground a little

a little
you need to accompany that with a nice ECU to really benefit.

headers + exhaust would help too.
or do you already have those?

Add an adjustable fuel pressure reg, larger throttlebody.
If you're going to change cams though it's an ideal time to add the cam gears to save doubling up on labor.

Look around there should be workshops who can enlarge your standard TB.

NO! neither are going to help with a stock ems. anyway, bigger TB is ***NOT*** always best for NA. again, as per my previous comment. air velocity is KING when it comes to NA set ups. a bigger TB is going to slow your air down. if your velocity is already too fast, then yeah, go bigger TB. if not, then leave it be. |

ozy, you can do all the afore mentioned and gain a few kW before EMS and starting hardcore mods. or you can strip weight out and improve your power/weight ratio. if you don't need them or you need the performance (track day etc) strip out:
- back seat - everything in the boot, spare, tools etc - passenger seat - stereo (a big fat sub can weight a lot on its own) - glovebox and contents - dash and center console - door trims - carpet (it isn't nearly as light as you'd think) if you can get away with it on the the track ditch your headlights too, its good for cooling and a few kgs. in some cases you can use a dump pipe instead of a full exhaust system, do it and remove your exhaust if you're really into it: - swap heavy rims for lightweight ones - get light racing seats if you strip your 1200kg astina down to 1000kg thats 16% increase in power to weight before engine mods twilight how much do take out before a day on the strip?

I disagree regarding an Adjustable FPR on a BP engine + stock ecu. Made a difference to my NA BP (with intake as well).

i dont take much weight out of the car anymore, only about 50kg i think (and most of that is the spare tyre).
in terms of if a fpr is good or not, there's a big difference between feeling better and actually being better. the stock ecu is pretty dumb when it comes to open loop control (ie high rpm, wot). all it does is work out the amount of air coming in and inject the amount of fuel. what happens when you raise the fuel pressure is that you're getting more fuel than what the stock maps reckon and all of a sudden you're running richer than before...and considering almost every car is excessively rich ni open loop from the factory doesnt help. |

Both are valid and both are valid for a stock ECU. I did say 'Add an adjustable fuel pressure reg, larger throttlebody' meaning that they will complement all above mods, not that they were necessarily starter mods.
