Hey guys, I'm in the market for an RS soon hopefully when the right one comes up, I was going to buy a standard one with the view to slowly adding bits to it with the ultimate goal probably being a 400 package, I like Collins as I've been out in a cp370 and it was amazing. The thing is its tempting cos you can pick up a tuned car for around 1-2k more than the price of a similar spec standard one, but do you think I would quickly get bored as let's face it, part of the fun is adding bits to it yourself and making it your own? But I know it will cost more. Also how will the fuel economy change? Will it use more when driven the same ie driven sensibly commuting to work? I know they have 550cc injectors so I'm guessing it will be worse.

Cheers.

Mine has got better since adding the 550 injectors.

Initially it was awful late teens. But over a few tanks its really settled down.

Now getting 21.8 just driving to and from work. And can easily hit over 30mpg on a run somewhere. With a little boosting along the way. Work is a quick 10minute drive.

Press loud pedal and its awful though.

Going to be a lot worse than the civics you are used to though mate.

I'm only 385 map. But shall be 400 in next week or so

You'll probably get around 60/5miles to ÂŁ20 mate. And if you hoon it everywhere then a lot less.

On a run they are ok. But short trips not the best IMO.

Trust me I had my type r for 3 years. The RS is a lot worse.

Even when just trundling along when you accelerate to get up to speed my mpg counter just drops into low figures.
If you're worried about fuel though it ain't the right car lol

RS direct due awesome deals on parts and no movement on the cars lol.

Sure adey would sort you out a mint deal on parts though.

Just do it joe :-0

You say you drive sensibly. And don't hoon it.

Until you get in the RS with exhaust and make it pop and bang an worble everywhere. You won't be sensible lol

the computer is correct even with bigger injectors I've clocked mine a fair few times and even when it says 120miles left I normally do almost exactly 120miles, never fill mine to the top unless on a run so can't comment on miles from a full tank.

As we all know our engines are thirsty but if you use them rite(economically) they aren't too bad, I can make a quarter of a tank last a month just.....

Full tank of V-power around ÂŁ75,and I get between 230-290,my drive to work is at 1:00am,only 5 miles with no traffic,doing around 50mph,doing this constantly for a tank of fuel would easily do over 300 I reckon,its when you get a clear road and a heavy foot that the gauge drops dramatically,but its worth it
My mate drives like a hoon for a big part of his tank of fuel and he gets about 150 miles

and both cars are JWR 100

Think I got 22mpg on my way back from having the 400 fitted but for me a big part of the fuel disappearing quicker than it could is due to the sound as once you've got a few mods the car sounds so great you have to give it a little bit more to hear the exhaust and induction noise coupled with the pops and bangs its
