never done it so dont quote me on it but i believe it will fit..
think u can block the injectors off with 1 pence pieces or leave injectors in.
also read something abt drilling a waterway, dunno if u will need to using webber sorry im unclear on this though

i once put 1.8v carb head on my 1.6 block
also used gti cam
gti manifold and exhaust system
also had a webber, it flew around with this done, might be worth athink??

Find a PB head and bang it on your 1.6 - the combustion volume is made up in the block not the head.

Spin the injector collets out, drop a penny in each and tighten 'em back down.  I never had any issues with mine for about 2 years on a 1.8 carb motor.

With a correctly jetted Weber you won't regret it - nice rev hungry little monster  :evil:

found some one local who has a gti cam for sale ... if i was to fit it and get the engine tuned will this alone increase performance?

thanks

yes it will increase performance because it is essentially a higher lift cam AFIK  :cool: oh yeah and i was also told that with a webber carb if you run a "little" timing advance it makes it a bit faster aswell and no i dont know how much a "little" bit is  :grin:

i guess it wont be that noticeable but how much faster are we talking with the GTI cam, webber carb and tuned??
(hoping to get a gti manifold and exhaust system on her to but not any time soon!)

thanks
