What kind of BHP increase could i possible see, what size TB's would i need? i presume the smallest..
fook off thats my crazy plan lol
the smallest i belive are 40mm ones. youd need a fairly well worked head and a bit of a mad cam. basically a T40 carb setup but with the ultra (fast)tuneability of TB's
it will be expensive but hey ive got other ideas too ;)

what cam would you suggest?
i wanna be able to nip @ the heels of those 1.4 boys Muwhahaah
any links to places that sell cams?
and would i need a full new set of rockers and lifters, or could i just slap tha cam in seeing as its new ?

they are expensive, BUT the info is very coprehensive there.
a kent AST2 seems a good cam for the T40's. but with TB's prehaps an AST3.
i'd be inclined to go for a full kit so taht you get minor reliability. since peak power will be around 7-8K lol screamer ;)

lol.. awesome! ?244.. hmm not much more expensive than getting a full GTE cam/lifters / etc... from vaux dealership...
lol @ 7-8k.. car will be like a honda vtec then lol
bear in mind for TB's you will need the bodies (obv) a mappable ecu, a mapping session (followed up by tweaks on the road), head work, cam/bits, bottom end rebuild anb strengthen etc.
im considering a 1.2 16V head but thats irrelevant.
all that will cost around ?3-4K possibly more
and to get the most from it you will need to strip the car of everything :D
imo TBing a 1.2 is a fairly comitted task. ie you have to be willing to gut the car, have no expense spared on bits etc.
some will say its silly and a waste of money, oh well

well, cant u stick TB's on a carbbed engine.. or am i stuck with the option of twin 40's
you can put TB's on a carbed engine.
it will cost loads if it was injection or carbed.
easiest route is T40's with cam and head work. but its still going to be fiddly on a 1200 :)

is an AST2 cam much better than an AST1 for T40's?
What about if u had a standard Twin choke carb or Weber 32/34? WOuld AST1 be better?
I heard that the tick over on the ast2 is bad.

iv heard this too BUT ive NEVER had a problem
car allways idled smoothly......
BUT
when i put a blydenstein head on my engine. i assume the 32 34 couldnt deliver enough fuel with the lumpy cam. and then it wasnt such a ncie idle.
