I can get a pair of these cheap

Wondering if anyone has jetted these down to suit a worked 5k?

 

 

And wondering where to get a manifold

Read the FAQ PLEASE!

I've got a pair. Just awaiting my manifold and THEN will get a 5K.

 

I'm sure they can be jetted down to work on a 5K.

You don't need to re-jet SU's, they will work on stocko 3K even if they were used on a Datsun L28.

Thie thing about SU's is that unlike a regular carby they work on a vaccum set up, so rejetting is unneccessary.

They may work from a L28 to a 3K.....doesnt mean the 3k will actually run alright.

 

SU's need tuning and the right needles, not to mention the right size to get them to run right.....saying you can pull them off a 2.8L and put them onto a 1.2L is utter bullshit.

Yup. You need the right tapered needle to get them to run properly.

I am sorry I was misinformed about SU carbs then, a mate of mine who is a mechanic said it, ages ago when I was looking at going this way.

Some pics if you would like to look.

 

ah su`s i run a set of 1 1/2" hs series on my mild 5k well static comp is 10.3 : 1 but the camshaft is not that big. but yeah the needles do dictate mixtures from idle through to peak rpm but i run no. 6 needles and .090" main jets. but that will prob different to 1 3/4" carbs.

i am thinking of changing to efi as i have complete setup except throttle cable but not sure if i want to sell them as they make the best induction noise.

Where'd you get your ram tubes from kickn5k?

I used to run Ram Tubes on my SU's. I purchased them from Hardiman Auto Parts in NSW. They also have Redline foam socks available too.

Alternatively, my local MG Workshop sells locally made ones. You could always try businesses like that.

Hmm, i think i might be passing on the ram tubes. I'm now after a pair of MG Metro plenum's :P
