Williams Conversion





just wondering what im likely to pay for a williams engine, 16v gearbox and manifold, and ecu plus fitting into a 1.2 rl shell?? heard id need fuel pump and that, not sure about driveshafts. any ideas on prices?? cheers. looking for it all doing in november/december time.
 


You can use stock shafts I think but they wont last.

Williams engines is £600~1000 depending on ages etc.

Gearbox say £150

Manifold other bits etc (you need a new bonnet since the 2.0 manifold wont fit under a normal bonnet) say £300

Fitment into a 1.2 shell say £1~1.5k

Your looking at about £3k Id say.

WHy not buy a proper Williams for that sort of money plus you get the better suspension brakes and the better Williams gearbox.

Even 2.0 converted Valvers are going for under £3k. Personally that would be the route Id go down rarther than the expensive conversion route.
 


tbh i didnt think it would be that expensive! think the fitting price is wrong though i did get quoted £150 for an engine fitting if i supplied all the parts.

you dont need a new bonnet at all btw! the manifold does fit under and the purpose of the bonnet vent is to let some of the heat out! id upgrade the brakes if i was you, also the shafts will get chewed in about 10 minutes! if you havnt got power steering you need a manual rack alterntor kit off bondy otherwise you aint gonna be abl to attach your alternator at all or drive your water pump, im running uprated spax anyway so im not converting the susp, you need all ancilleries, wiring loom and ecu. why not do it yourself and save £££ on labour? im doing mine myself along with a mate and depending on how mine goes if your serious we can talk on a price for us doing it, i live in sheffield but the place is only an hour away in lincoln and we could meet to get up there, but without being funny you have asked these questions lots before so only ask me for a price when you have all the bits and are definately doing it :)

You might aswell buy one already done,i think nick at hillpower has got a williams lump knocking about id have it rebuilt first or atleast stripped down checked and new gaskets, water pump,tensioners etc

I was on about the intake manifold there no way youd get the normal bonnet on over that.

Id recomend running highter poundage front springs though say 200lb.

ill be running valver lowering springs an it for now until i have the ££ for proper uprated ones.

the normal bonnet fits the same as a valvr one but the vent part is just raised up it fits no different and isnt any higher
 


Smokeys conversion into his Hybrid cost approx:

52k Williams Engine, engine, gearbox £1100

Fitting £500 (Bearing in mind ours was a straight swap from 1.8 16v to 2.0 16v)

Replacing major engine components such as starter, oil pump, water pump, cambelt and tensioners, head gasket, alternator, uprated Group N clutch, all fluids, all belts, new low temp thermo & low temp fan switch, new engine mounts cost about £1k with the engine out it would of been double that at least if we had of done that all once engine was fitted. We wanted to make sure it dont need fixing for a cpl of years at least.

You will need a valver/williams bonnet so add an extra £300 to that.

So we paid about £2600 for a straight swap and your lookign at at least £3k without uprated brakes, suspension, exhaust imo

Since you have coilovers you can use normal o the shelf springs. Demon tweeks sell them for £50 for a pair. Almost any weight you want.

u will need to either cut some of the inside of the bonnet away to allow room for the inlet manifold, or get a proper bonnet as they dont shut properly and rub away at the inlet manifold if not done right, also losing a bit of heat away from those engines always helps

Your lookin at alot mate!!!

Mine was a good price at Just over £1600 for a 45k engine, recon willy box and some replaced parts such as cambelt, clutch etc!!!

Id say 3k would be a good price into a 1.2 shell............Deffo worth looking into buying the bolder looking hybrid valver or williams id say!!!

BigChriss one looks in good con and by all accounts a fast one aswell............Only 3k!!!

BigChriss is a beast, i had the pleasure of picking it up for him from GDi a couple of weeks back, and its defo faster then my standard Hybrid, the extra torque is amazing too in comparison.

£3k is a steal and if it was mine id ask £4k for it and wouldnt budge.

My conversion cost a little more in the end as i opted for the donor Williams3s complete interior too, even suit carrier, top dash, clock, heater dials etc

std bonnet without the bulge fits over the F7P/R engine no problem.

And 200lbs for front springs on the road is EXTEEMLY hard and will make the bounce all over the place.

When i fitted a standard bonnet to my valver it cut away at the inlet manifold which was rather deep.

Probably hits once the engine starts moving up/down.
 


thanks for all the feedback, i will probably modify the standard bonnet as i want to keep the standard 1.2 look. i may end up dropping to a valver engine as i know they can be picked up alot cheaper and possibly upgrade in the future. that a better idea? dont quite fancy buying a new car just yet, perhaps next year.
 


The idea of the bonnet is to release heat, this in turn reduces the risk of you blowing your headgasket and getting a £500+ bill.

it helps cool the exhst manifold area really....heat "release" only occurs at standstill

naturally if u were to use the non-16v bonnet u would fit some sort of vent

Id go with the Williams a 1.8 will be only slightly cheaper say £250 Vs 750 so there only £500 difference since a 1.8 youll still want to change all the belts etc and instalation cost is the same.

But dont you get a ram air effect pushing all the hot air within the engine bay out the bottom of the engine while moving:confused:
 


well ill have to see how much it will all cost in parts since i kinda want the engine to be running like new, get all refurbing done while engines out etc.

am i right thinking my current cat-back exhaust will be ok aslong as i have a 16v/willy decat and downpipe?

Anyone know anyone or anywhere i can get the parts i need really cheap? and are williams shafts better than valvers?

cheers
 


16v/Willy CAT/DeCats are different.. it all has to match.. 16v downpipe with 16v cat or Williams downpipe with Williams Cat.. even then, the mounts are different between a 16v and a Williams after the cat towards the backbox.. but thats not going to make much difference.

Williams driveshafts are also different to 16v driveshafts because of the wider track.

Theres a great belief that the 16v and Williams are much more similar than they really are, heheh.
 


yeh im assuming it will make a difference to my bank account as well lol. i think this will end up costing alot more than i first planned on, not really any point doing a 1.8 conversion to get a williams lump and everything else shortly after really.

Would i be better off splashing out for the williams conversion than the 1.8? is it going to be money well spent?
 


Yes, Williams over 16v is probably worthwhile..

But, it puts you in a similar position to me when I had my 1.2.. it was just better to get a Williams to start with.. and then you do get the track, brakes, interior, and everything else which makes a Williams. Just things like the rear track being wider on the 16v/Williams... its never gunna happen on a standard none-16v shell as the arches would need changing else theyd catch..

16v -> 2.0 is fine, as it really is more of a straight swap...
