Mk1 2litre Turbo Conversion

[Plattsy]

This has probably been asked a million times but has anyone got a wlliams engine turbod? im after a conversion for my williams/valver hybrid but im going to be buying it in parts instead of saving up cos i cant save up for life of me lol.
Other questions are, if i had say uprated cams already would i have to have new cams to suit a turbo? same goes for head being reworked. Thing is im wanting cams and headwork done before turbo so wondered if it would need doin again afterwards.
What sort of boost can i run and how big a turbo etc. would it be possible to have throttle bodies aswell as turbo? should i use a willy box instead of 16v? willy driveshafts instead of 16v?

Who do turbo conversions for the f7r?
Cheers!

BB have a 255bhp williams turbo :evil:

Best talk to BB about it all, they'll be able to give you proper advice.

BB do turbo conversions as do k-tec.

You can use 16v or williams shafts - it makes no difference.

Best to use strongest gearbox you can for obvious reasons - this means willy box.

Bit pointless turboing a 2ltr engine IMO - they're expensive to beginning with and you'll basically get the same torque by upping the boost a little on a 1.8...1.8 is generally stronger too. If i were you, buy a cheap 1.8 to turbo then sell your 2ltr to fund it.

You can have throttle bodies with a turbo but pointless again - the weakness with turboing the clio is the gearbox and you'll easily reach that limit with a hi boost turbo!

Speak to Nick Read as he knows all.

The BB low boost conversions are crap. tried and tested!

 

[diamond geezer]

turbo a valver lump as suggested, and sell williams lump. the valvers rev better and as said above you will need a williams gearbox, so dont sell that bit. i wouldnt bother getting your engine cammed etc, get it all done at the one time so everything is matched

 

[Plattsy]

id rather keep my 2litre though. if bbs conversion is crap where can i go?

 

[u33db]

BB did Nick Reads and just about every other 16v turbo in Britian - nobody has done more development on them!!

Perhaps what Tom is referring to is that their low boost (190-200bhp) isn't that much quicker than a cam'd 2ltr...their hi-boost (240-250bhp) is in a different league though. Still, the low boost doesn't warrant the word 'crap' by any stretch of the imagination IMO...

BB is the best with k-tec coming afterwards (k-tec only do low boost though). I'm sure there are other places that will do it but not nearly as good.

As said, pointless keeping the 2ltr if you're going to turbo it and, if i may say so, a waste of a rare engine...

 

[Plattsy]

so what power would i be looking at then with a high boost conversion, cams, headwork, etc and what difference will throttle bodies make? I will be using the car primarily for track runs, not day to day driving. although it will be road legal. I will more than likely be gettin a 6 speed box which im assuming will be stronger than either 16v or willy box.
Is there any other engines thtd go in the valver shell?

 

[u33db]

High-boost with headwork etc you'd be about the same as Nicks which was about 250bhp or so.

Throttle bodies with a turbo? Well, assuming you could get someone to fit them then not much difference. The main benefit of fitting TB's is they flow more air than the std inlet but since turbo is forced induction that arguement kinda becomes non-existant!

The gearbox is the key though. Theres no point building an engine thats capable of 300bhp+ (or whatever) if the gearbox can't take...and non of the existing 5-speed boxes can AFAIK (for a prolonged period of hard drving). 6 speed...well i don't know if you'll get one to fit the mk1 shell?

As for other engines (yhan the 2ltr you have) you're only going to want ones that are more powerful...thats only a tuned GTT in reality or perhaps a tweaked 1.7 turbo. There was a F4R (172) conversion done on some foreign site a while age...a few people on here said it couldn't be done but obviously it can. Nick Hill says he could do it anyway...

 

[_Tom]

Well i tried and tested my car against a BB low boost turbo conversion...my 2.0l isnt cammed and was still slightly quicker. Tested twice!!

The BB turbo i know of has melted two heads, snapped drive shafts thus killing gearboxes...the list goes on!

He had basically spent 15k getting the conversion done and keeping it on the road for a year and a half!!

 

[dannyboy]

the 1.7 engine woul dbe the volve engine u33db? i thought these was massively limited in some way??

 

[u33db]

Yes, the ECU is the problem on the volvo lump as it limits boost IIRC but there are people who can get round it.

Prima do a 1.7 conversion for the GTT and i'm quite sure that doesn't use the volvo ECU or anything like that...it's either a bore out of the 1.4 block or a hybrid of GTT parts and volvo/renault 1.7 BE...might be worth looking at?

For the effort i'd stick with the 1.8 16v or 1.4 GTT though...easiest and best.

dont mess - vag it if youve got £5k to spare (285bhp)

5k for a vag engine including fitting and modded to 285bhp ??
