twin 45's on a gti

hey thinking of changeing my gti over to twin 45's, has anyone done this to give me some advice?

would think 40's would be better. not particulary worth the effort without head and cam work.

have you done it then? did you just use ur gti wireing loom?

no, i have not done it. seems alot of expense for little if any gain and lower fuel economy.

ive just put a valver on carbs in my mk1 and the loom does not need to be changed the only thing that i have changed is the ignition module the run the carbs it got the module of a 1.3 polo hope that helps

id be greatful if you could do a break down of whats involved as im looking at puttin mine on twin 40's

well ive just done mine its not runing but it will be soon if u have got a gti to start with then it will be sound or if u all ready have a valver in your mk1 then its a case of takin the injection off and boltin the carbs on and regulating the fuel comin in to the crbs by a fuel regulater and changing abit off the loom
if u need to no any think specific mail me by all means
ive only got 1 problem and thats that the top water pipe is stuck between the carbs

ash, i have seen someone with a specific water pipe to go with the carbs
i will look for it

cheers mate that will be a great help as its on the mk1 gti rad at the mo

ash any chance of a few pics so i can get a generall feel for it???

cheers

i would use a facet fuel pump, fuel regulater (malpossi or filter king)
u need the inlet manifold, two carbs (idealy a matching pair) linkage kit, choke cable for cold start and i would advise in getting a new throttle cable. also dont forget to get a new inlet manofold gasket, and four socks (airfilters)

twin webbers are abit of a pain to get set up running perfect and a few people reckon that dellortos are much better as they dont need setting up as often as the webbers, i would advisew you get a fuel regulator witha built in gauge as these carbs dont want to be no more then 3psi? of the top of my head and the regulater must have a fuel return port to allow for the excess fuel to return back. (so it should have 3 fuel lines coming of it, fuel feed fuel return and fuel supply to carbs)

sounds ok but i dont mean to sound stupid but what do you mean matched????

No - Pressure is way too high…

As said above, you only need 3 to 5 PSI, so would need a Pacet pump or similar with a regulator to control the flow.

ill try to get pics of the conversion mate its simple really i just started it and then went from there really but any think u want to no just pm me mate
