K14 Modifications

Hi all,
Do we eveen have any other k14 owners here?
Im planning on doing some modifications to my K14 0.9ig-t,

lowering springs,
H&R 35/35 there are other choices eibach/vogtland/pi/apex/direnza, as far as i recall H&R were decent on almeras anyway.

Dump valve,
Has anyone fitted one, does it sound like a mouses fart?
the only one i can find specific is a forge i would like to fit a HKS if i can find a geenuine one for a reasonable price, and probably blank off where required

wind deflectors,
team heko, anyone fitted some ? is the fit decent iv seen some excellent and some **** fitment

That will probably be it for a while , i will need to be able to refit the standard bits for servicing/warrenty upkeep, id like to fit a panel filter ill take some measurments and see if there is something that will fit the standard airbox


Do have a friend with a Brabus smat fortwo that uses the same Renault engine 0.9 turbo. But puts out 109 bhp as standard. He tried a tuning box but was underwhelming so got the ECU flash at a speciaist. Now has 135 bhp and has been reliable and no problems other than wheel spin in the wet.
Not sure if the turbo is bigger on the Brubus to start with but the re flash made the car much more fun with better low down torque.

Hope this helps.

I don't think we have many K14 owners on here. The H4Bt engines are utilised in a lot of different vehicles between Nissan, Renault, Smart and even Dacia.

I'd imagine the Brabus variant has some slightly different hardware compared to the otherwise standard 90bhp offerings. The spec sheets on H4Bt lists maximum boost pressure at 2.05bar, which is pretty typical of todays modern engines. That'll be a piddly little turbo that gets up quickly but lacks efficiency when pushed. I'd imagine peak boost is fairly low down and tapers towards redline, which is why you don't see much in the way of gains compared to other marques which are aimed at the performance end of the market.

I'm used to a K11 with more power than I honestly need, so any factory offering from Nissan isn't going to tickle my fancy. Still, with H4Bt remaps stating +20bhp gains over stock, it will certainly help get that big 1052kg body about :)
After resetting the ecu and fitting the new performance chip now pushing around 100bhp out of my .9 Acenta got a reading of 0-60 in 10.01 in wet conditions with a gps accuracy of around 19ft

Not had major amount done to my k14 other than chrome badge, all front plastics (fog light surrounds, lower bumper, lower grille) and the faux carbon and fog light surround on the rear colour matched, and the nissan badge shaved from the rear. Few stickers on the inside of the sunstrip and dashboard and thats about it, in the next couple of months I'll order black
17x7 +38 work emotions on the car
Our Dci needs more power and better brakes and dampers.
Planning a remap when the warranty is up, braided hoses and good uprated pads. Maybe the N sport spec dampers would do it.
All a long way off!
I have the Diesel TEKNA Model. only mods i have done are the added bits of plastic on the valance and lower doors, and added the armrest in the centre console. i may consider a remap to smooth out and improve the low speed pull on the diesel.
I recently fitted a set of work emotion kiwami and couldnt be happier with how it looks. However mine is going back in november as I put a deposit down for the GR Four yaris
hi all...

nice to be here with other k14 fans!
love the car but upgrades are always welcome.
so i lowered the car about 35 mm (H&R springs)
put 18 inch wheels
upgraded the bulbs to led's
put a sharkvin antenna
removed the micra badge
got a led strip for daytime running that also turns orange when blinking (sequential)

any tips for improving?
chip tuning is in the planning
