Cheers, that would seem to confirm cd150 are sufficient. Are you running an efi set up?

Glang I think it says that on Chris Witors summary of the different carbs used by the big triumphs. I've found calculators that people use to determine the size carb they need, it uses the displacement of the engine etc to give max cfm and that suggests that even at 100% efficiency (for the engine-which it will never achieve) the cd150 should be sufficient. Tim W, you've recommended the PH2 to me before on facebook, I'm definitely considering it, though I spoke to newman cams and they recommended the ph1. I've also talked to CW and he thought the standard gt6 cam would be better than his modified gt6 cam, which in turn is less cam than the 150bhp cam or PH2. So it's safe to say I'm confused and have no idea what to go with! (Un) fortunately a change in circumstances means I don't have a garage big enough to pull the engine at the moment so I have plenty of time to decide!

Thanks for clarifying that, I'll stick with the cd150, which has the added advantage of keeping my life easy as well. I'll spend the extra time/money having the standard manifold cleaned up to get better flow to cylinders 2 and 5.

Thanks, yeah google shows lots of good old threads bit they seem to be innaccesable now. My existing cd150 would be the same as the gt6, just with different needles so it would be easy to just get the gt6 needles...but then because I will use the better later intake manifold I'll still end up having to make up adapter plates etc. And yeah I have heard that it may be too much carb, but I've also heard that the HS6 from later cars is an upgrade and given they are 1.75 inch I figured the stromberg's would be the same. I know there are old threads from people with gt6 who have used HS6 and cd175 so I would be very interested to hear from them. Thanks for the tip on the TR6 exhaust, I have an existing stainless exhaust from the front pipe back so may end up just getting a 2 to 1 piece made up for that.

Hi, I'm planning to upgrade my 1970 2000mk2 with a gt6/vitesse cam, SU intake manifold, tr6 cast exhaust manifold, and a set of cd175 carbs. Has anyone run these carbs on a 2000/gt6/vitesse? I'm thinking I'll start with a set of the later tr6 needles or maybe tr7 needles as that engine was the same capacity. I don't expect any to be perfect but wondered if someone might point me towards a good starting point.

I'm getting ready to paint my 2000Mk2 (which will be stripped to bare metal) and wondered if anyone knows what type of paint triumph used to paint the 2000/2500s, stags, tr's etc of the era? I'm guessing its a single stage enamel?  

This is purely a question that has arisen from my own curiosity but I have been browsing engine swaps for the big sedan and it occurred to me that the 2600 engine from the sd1 would be the spiritual successor and in many ways right at home in the 2000 as it was designed by Triumph.  Has anyone heard of or done this swap? From what I have read the sd1 engine would also be a good candidate to make decent power.

Thanks, That's looking like the route I will take. With your set up does that make the front of the car slightly lower than the rear? I'm also a little confused that CW lists the springs on his website as being for 200, 2500, and stag? Cheers

Hi everyone, longtime lurker, first time poster here. I'm looking at options for the suspension on my 1970 mkII 2000. I'm looking at Gaz front and rear, superpro polybushes (being based in New Zealand they are a lot more accessible than superflex) but am unsure of what to do for springs. The obvious choice is chris witor, but I quite like the look of the monarch progressive springs advertised for the stag and have noticed a lot of suspension components are interchangeable however I'm concerned about weight differences between the cars and whether the stag springs will sit at the correct ride height. I'll probably go for 1 inch lower all around. So my question is, will the monarch stag progressive springs work on the 2000? has anyone done it before? or does anyone have any tips for stuff that works well?
