Next year me and my bro are thinking of finding a mint (exterior) williams or valver high miles on it and recon the old engine and turbo it. Strip it out completely! Take it on track and 1/4 miling. Has it been done and one on here got it or any info advice would be great!

You dont want a williams if your thinking about turboing it - you want a valver. (for many reasons) one being that the crank is alot stronger (s/s in fact) allowing you to rev harder / longer.
Tho TBH - why not just buy a car thats already turbod like an R5,RST,scooby - will be alot cheaper in the long run if your just thinking / dreaming about track days.
i suspect a light FWD turbo car is totally useless on 1/4 mile

This aint too bad tho...
B9 GTT
Having now gone to a good home in Newcastle, this was an animal of a car. The best time run in the car at Santa Pod raceway was 13.05 standing quarter mile at 111mph. The car is extremely well known and was featured front page in Fast Car magazine last year, and was also on show at Max Power Live, USC 99 and 00, The Motor Show 00 Fast Car Stand and Trax 00 Fast Car Stand.
B9 also won Best Interior at Mean Street Cruise on two occasions in 2000.
Catch B9 on television later on in the year having been filmed at one of the Cruises last year.
1st at USC 99 13.9 at 109 m.p.h. (1st day ever run down the stip)
2nd at USC 00 13.2 at 109 m.p.h.
Williams is about 150bhp as standard. R5 GTTs are 115/120bhp as standard but weigh less. Worth noting that my mate spent about a hundred quid on his (bleed valve etc) and saw 160bhp the same day. Theyre far more tunable and will be faster for cheaper.....but thats true of any turbo i suppose!
i was considering this as my next mod but booger that !!Quote: Originally posted by rockport on 03 March 2004
Didnt mean to say S/S - meant "Steel" and if it isnt stronger then the williams crank then BBPT must be talking out of there arse - personal i know who i would believe.
Its more a case that the williams crank is physically stronger as it was taken from a diesel lump... but the crank from a 1.8 16v is suppose to be better for tuneability and high reving
Is the crank shaft strenght that important has anyone broke one and been told that if youd had the other crank you would have been ok?
The diesel one (turbo) held back 93hp at ~4k so when you rev the engine to 8k then it should be good for least 186hp as doubling the revs with the same torque gives twice the HP and thats before you take account of the extra strenght the company build into them
Looking at the cransk wont tell you which is stronger you need to know how they are made one may be lighter and smaller but much stronger.
TBH either crank will be easily up 2 the job. its the rods/pistons that should be considered 4 high boost.
it isnt the power that will do the damage, it is the torque. but ur right, there is a safety factor, thats why either will be up 2 it!
Ben, wot is the effective piston height difference between 7p and 7r at TDC?
Im gonna ignore all the 5GTT vs. F7 engine nonsense - apart from to say that theres no substitute for capacity, as Ben so eloquently put it, an extra 400cc and 8 valves makes a big difference if its turbocharged the same.
The thing Im more interested in is why you would want a turbocharged motor if youre building a track day car? Id want a highly tuned NA engine for track work, not a turbo. I drive a turbo valver because I want a bloody quick road Clio and it is, plus it serves my purposes on the 1/4 mile. But the characteristics of turbo power delivery are definitely not what you want on a track, NA is the way to go.
