performance mods for williams 3

[gaunty]

hello guys looking at getting my williams 3 up around the 200bhp area were would i start and can this be done

[trickywoo]

Thats going some if you stick to the NA route.

Cylinder head and cams would be the obvious place to start.

I would imagine 200bhp would make for a very peeky power delivery also likely to be lumpy low down due to the type of cams you would need to run.

Sticking a turbo on it would be the easiest thing to do.

cheers for that mate any ideas were i could go for a turbo kit for it just really want to bring the speed up on long bits of road its great on the bends and that

BB Tuning used to do a turbo conversion for the 16V and Williams - you're looking at £6-7k all in.

cheers for that gives me some idea i might de cat it then fit a good induction kit and chip it then get it rolling roaded and see what i end up with after that i might invest in a turbo just need a car that can keep up with my mates 206 gt180

Just bear in mind you can out-corner him any day of the week...its not all about power you know...

Induction kits are a waste of time IMHO. Quite often they end up giving less power.

If you ever need any cylinder head work doing just bolt on a new one that has been properly polished and ported, preferably with bigger valves. Might not give a huge amount of extra power but will make the engine feel much nicer.

i didnt know that about the induction kits i was always told to get one
been looking at cams and throttle bodys because as much as i would love a turbo bit out of my price range which company would be best for the bits because the price for parts differs alot from site to site for the williams and has this been done befor

[number2301]

A healthy 150bhp Williams should keep up with a much heavier 180bhp anyway shouldn't it?

[gaunty]

my one has very high miles 189thou on the clock its my uncles old company car so probably not running at 150bhp i mean its never missed a service or any thing but with that on the clock its taken its toll a bit on the performance so i need to bring it back up to date because in the summer i want to take it on the track so all help very much appreciated

Get the engine rebuilt properly.
And it will be quicker than it was from factory.
Best performance increase per £ on these engines now.
De cat's are said to give around 3bhp, if your after something cheaper lol

[gaunty]

i had a look on the net and there are loads of places that offer engine rebuild's were is a good place to go and am i looking at massive amounts of money

[megane225]

depends on how much you want to spend and what excactly you want from it, i agree that the head is the first place to begin , but again if you need more than NA go the turbo routewhich is cheaper.if you can fabricate some parts you can save lots of money. buy a used turbo and build your own exhaust manifold , 0,3-0,4 of boost will be enough. cheap piggy back ecu's can help the fueling . you wont need an intercooler .

[gaunty]

i am looking at spending about 2k on it and i would like it to just be faster from stand still or when on track coming out of the bends and what are piggy back ecu's and stuff i build houses for a job i can do quite a bit on cars but if i was to try a make my own bits and stuff me and the car will both blow up

[megane225]

ok, if i was you i spend my money on a complete exhaust system s/steel ,air filter and have the head done , port and polish and chip the ecu /or use an paralell ecu (piggy bag)which will allow you to tune it properly. this i assume will give you about 30hp which is enough i think. also you can change the cams but this will cost far more , or find second hand.(you gonna have to change valve springs too) you can find many used parts on ebay amd save money but advise someone before you bit on to something.cheers

[gaunty]

thank you mate that is great cheers

Just don't get any of their bodykits.

hi mate been reading ur posts. I too was asking the same questions myself not so long ago when i bought a williams 2. I so far have gone down the induction kit route and a decatted powerflow exhaust, i have to say this did make a nioce different and is much quicker to rev now. There is a superchip for sale on ebay for 60quid which claims an output of 192bhp with induction kit and exhaust. a big bhp number should'nt be ur outright goal though as you want it to be driveable and still have some low down torque, I too would have thought you would beat a 206gti 180 i would challenge him to race me round oulton park in mine anyway. Also whilst enquiring about tuning my williams i rung a local tuning garage that have a race tuned ready built williams engine with everything rebuilt and done, cams, valves the lot, they claim they built it for some lad who never came back so its just sat there ever since, they want about 2- 2.5k though if my memory serves me right, i remember it was out of my current budget anyway, hope this helps, jack

[gaunty]

cheers guys for all the help i am going to get it rebuilt and add cams and a chip and stuff and see what that
gets me its just gone in for its mot today and its not going all to well at the mo they had to stop it due to my car over heating and the fan not working bloody car
