Tonyloz Posted February 18, 2017 Report Share Posted February 18, 2017 Hi Where is the best place to buy webbers and manifolds? Quote Link to post Share on other sites
TR 2100 Posted February 18, 2017 Report Share Posted February 18, 2017 That is a very broad question. Size of webers - 40DCOE, or 45s, or hype-rare 42s? Preference/requirement for top linkage or underslung? Preference/requirement for cable of rod linkage? Would Mizunu alternatives meet your requirements? As for manifolds, be aware there can be a clearance problem with the manifolds and the brass fixings nuts. On my TR4, by the time the manifolds were ground back enough to allow a spanner on the nuts, the manifold wall was wafer-thin. I ended up with period manifolds but they are so hard to find that it is hardly a solution. AlanR Quote Link to post Share on other sites
Tonyloz Posted February 18, 2017 Author Report Share Posted February 18, 2017 They are for a 2.2 4 pot so 40,s Do u buy from the usual suspects or are there any other options Thanks Quote Link to post Share on other sites
mike3md Posted February 18, 2017 Report Share Posted February 18, 2017 I would have thought a pair of SUs properly set up would be as good as, if not better, than 40s? Not perhaps as nice when you lift the bonnet, maybe....... (Fetching my coat now........) Mike Quote Link to post Share on other sites
AndyR100 Posted February 18, 2017 Report Share Posted February 18, 2017 They are for a 2.2 4 pot so 40,s Do u buy from the usual suspects or are there any other options Thanks When I was considering this route, the path I would have taken was Moss during one of their 17/20% off sales. ......

Guest Posted February 18, 2017 Report Share Posted February 18, 2017 Mikunis/Keirins are the way forward. Quote Link to post Share on other sites
Peter Cobbold Posted February 18, 2017 Report Share Posted February 18, 2017 Who needs two carbs, one SU is ample when the engine is fed by a blower. Webers might give a marginal gain over SUs, but a blower will give 20-30% more oomph. So on cost-of-benefit basis the blower will win - easily. Peter Quote Link to post Share on other sites
monty Posted February 19, 2017 Report Share Posted February 19, 2017 I have Webers on one car & SU's on the other. Both pairs have been set up well & quite honestly there is not a huge difference in performance from one to the other, Webers give around 10bhp more. I think a good setup with SU's is a good compromise with ease of tuning/servicing & would probably be the direction I would go if starting from scratch. Cheers.

Drewmotty Posted February 19, 2017 Report Share Posted February 19, 2017 It's interesting to see a reply from someone with both setups and in a position to make a direct comparison. 10hp is well worth having but where in the rev range does that extra horsepower become apparent and at what cost in terms of fuel consumption?

Motorsport Mickey Posted February 20, 2017 Report Share Posted February 20, 2017 "10hp is well worth having but where in the rev range does that extra horsepower become apparent and at what cost" Have a guess... but then let me tell you, over 5000 revs but the SUs work a little better in the 2000-4000 revs area and are a couple of mpg better. This is all depending upon what cams general power delivery and driving style is of course. Mick Richards Quote Link to post Share on other sites

Around 4000 rpm with only a slight increase in fuel consumption with the Webers (around 24 mpg compared to say 28). Cams & other mods in both cars similar.Regards.

Mark1965TR4aBRG Posted February 22, 2017 Report Share Posted February 22, 2017 I have 45 Webers and they are so much more entertaining to drive. Webcon are a good source of all the bits. I have the Webcon top linkage and Bastuck manifolds. You'll need the anti vibration washers and a few other trinkets. Drop me a pm if you'd like pics to help you. ...you won't regret it!

Tonyloz Posted February 23, 2017 Author Report Share Posted February 23, 2017 Thanks for all the replies An extra 10hp would be good but to be honest its just the look of them in the engine bay! Suppose its a flash back to my youth! If anyone has a pair of 40's gathering dust let me know Thanks Tony Quote Link to post Share on other sites
