How about a bit of a fun thread, lots of us like cars and have done all sorts of mods to them and are probably boy racers at heart, so tell us what you have and what you've done to it to make it go fasterer or sound louderer :-)

I'll start off and you'll probably laugh ...

Smart ForTwo
ECU remapped to make about 78bhp and 115nm, now idea how fast it goes as it runs out of speedo numbers (not as impressive as it sounds!)
Next on the toy shopping list will be a better flowing exhaust and air intake setup.
... I'm aiming for New Zealands fastest roller skate ;-)

Just sold my 2009 Mazda 3 MPS, now have a Corolla (Moving overseas next year). Literally half the hp, life in the slow lane.

Since I've had it I've vinyled it orange, changed the wheels, added a windscreen, switched to a lightweight battery, changed seats, added some GPS monitoring, replaced all the indicators with LEDs and added a nice lasercut exhaust shield.I must have done other stuff too, but most of that was maintenance like clutch slave cyl, new wheel studs, dyno tune etc.

Buckets of fun.

For a shopping trolley, that's pretty amazing it can get that sort of speed up - the speedo goes to 160 from memory right? Having driven the 700cc turbo model, I'm not sure I'd feel safe going that fast in it, hah! :)
I hate to think how much runway was required to get to that speed though :P

lxsw20: Nice, what engine/drive train? 


Just a little Blacktop 20V 4AGE with a Megaquirt ECU. Oh, I added a BT-Serial converter so I can log engine stats wirelessly to my phone while racing. After dyno it showed I think 156HP at the wheels which is amazing given there's nothing special about the engine.

Now, the gent in Pegasus building the 500HP Fraser, that's going to be. Um. mental.

Cheers - N

1996 Subaru WRX STi RA (v2 - 81 of 555 ever built).  Has done 230,000km but engine rebuilt about 180,000km - owned it since 2004.  Link G4 ECU, 2.5" exhaust from turbo, and all sorts of geek additions to protect it against thieves since it's a very desirable boy racer car.

Unfortunately I had a seizure at the start of this year which means a 1 year driving ban but love the car too much to sell it - looking forward to getting back on the road next year...

Nah only goes to 140kph on my speedo, I'm thinking it got to 155ish, from the sound I think it wasn't able to get the exhaust gases out quick enough and was basically constipated :-)

Once thing I do need to get is a dump valve, the ECU remap upped the boost and when giving more than usual foot you can hear the turbo blades stalling during gear changes, so sorting out the induction and exhaust it should get going a bit better, handling is already good (tiny wheelbase) but I've some strut braces and anti-sway bars to go in as soon as I source some stiffer springs .. which will then mean I have to get some slightly wider wheels (especially on the front) .... it's never going to be a sub 6 seconds 0-100 sports car but it's fun to play with it :-)

Ahh the WRX ... I've not had a go in one yet!  But AWD and turbos are a great mix.

You should get a friend hoon around in it with you as a passenger, not point in missing ALL the fun :-)

Took a 335 for a drive the other day.  3 litre straight 6 with twin turbos.  Doesn't look like much, just a black family wagon.  Puts out 225 kw though.

Ex- STI, Evo driver - when I was much younger, all fiddled with  tongue-out

Typical boyracer stuff - big brakes, big wheels/tyres, de-catted exhuasts etc.

Then went Euro - Golf GTIs, fast Audis.
ECU tickle up but otherwise stock.

Sidetracked by some BMW diesels - E46 320d, E90 320d

Currently carless - as you can guess from the Useless Gizmos thread modern cars bore me, so looking for a classic that someone else has restored tongue-out

Been in a Cobra replica - tremendously fast in a straightline, scary everywhere else.

Was thinking more along the lines of a Alfa 105 coupe, BMW E30 M3 or aircooled Porsche 911.

Nissan Primera P11.  I have added: - 

Brake system upgrade.
Low profile rims (to fit brakes).
High grip directional tread tyres (more brakes a waste of $ without more grip).
New shocks (very slightly lower).   
New, lighter clutch. 
Cold air intake. 
After market manifold and exhaust (still quiet though).
Better plugs and leads.  

With the new tyres, shocks and brakes it now stops very fast and the brakes never overheat.  With engine mods I've gained just over 25bhp all up.  Big improvement in acceleration.  I've lost no discernible economy.  Most of the engine changes are about making better use of the same amount of fuel.  The low profile wheels are the only obvious modification, so it doesn't attract any unwanted attention from cops and idiots.  Very much a wolf in sheep's clothing.

I would really like to find some electronically adjustable rate shocks for it, but so far haven't found any that fit.
