Hi, i'm wanting to put a larger carby in my lc torana. the motor is still in the the working. so far i have only got a 192 red motor with a nice cam in it. the carby at the moment is a 2 barrel (stock?). i want to know your opinions on which carby i should use to feed the motor more juice and make it go a bit harder. i have a decent set of tripple su's and a 350 holley in the shed. would you use one of these or something else?. would an electric fuel pump increase the performance?

if you get them tuned properly, i'd go for the triple SUs. they're a beautiful setup on the holden sixes.

350 holley would be a big imprivement on the stromberg, but not the same as the Sus.

if your current fuel system is in good order, you won't get any performance improvement out of an electric pump, but it will give a more stable fuel pressure when used with a regulater. it's not bad insurance

thanks wabbit. i'll have to track down a decent manifold, linkages and install the su's. thanks for the help and speedy reply!! have a good Easter.

lc if you haven't found a manifold for the su's yet go to your local library & hunt around in the car section there should be a book on how to make your own it gives the correct angle from the head & distance from the valve i made my own many years ago & it worked extremly well

thanks oldman, but problem solvered. i bought a manifold of ebay. good idea though.

Oldman

that's great my way 's a hell of a lot of work but then i enjoy making things

Su`s dont need much fuel press, Anything bigger than stock pump is overkill, Let me know if you need any help tuning

i have know idea how to tune them i hear it's something that a novice shouldn't even think about! one guy wanted $200per carby to re-kit and tune.
if you have any tuning tips i'm all ears.

Where are you at with the carbs? what sort of manifold, got the linkages together? I have some spares here if you need.

Whats the condition of the carbies? and do you know what sort you have?

Anyone interested in 2" su`s; I have lots of them

it looks like i've got all the linkages. there is no choke linkake but thats alright. i have a WARNFORD manifold. the carby's are 1 1/2" su's with ram flow air filters. i have no idea how good they are.
i would realy like 3 of the 2" su's. how much? my email: dahl-helm@bigpond.com.au

hey ripgas, sorry im jumping on a pretty old post, but i don't suppose you've got a set of triple SU's still kicking around? ive just joined and bought myself a LJ GTR a couple of weeks ago. cheers

RIPGAS384

wow

have not been on this forum for ages! been lurking on gmh-torana

i have a set of 1 3/4 SU carbs on a lynx manifold freshly kitted with new linkages set up for a track car. owe me 600 bucks in setting up costs. make me an offer if you are interested. sorry no more 2".
