bobrogg Posted October 24, 2013 Report Share Posted October 24, 2013 After much thought I decided to switch from webers back to SU's for my TR6. I found a guy selling the complete manifold and carbs for 100.00 US and decided to make the change. After ten minutes I discovered that the previous owner had also changed the exhaust manifold as well and in order to make it fit he ground off two of the studs on the block to get the aftermarket manifold to fit. What should have been a 4 to 5 hour job is now going to be a weekend just to make it right. Quote Link to post Share on other sites
RobinTR6 Posted October 24, 2013 Report Share Posted October 24, 2013 Can I ask why you're swapping given the webers have a good reputation. I'm starting a rebuild here in the UK, and have a Pi setup but it needs rebuilding. I was wondering whether I should/could go with webers ? Quote Link to post Share on other sites
bobrogg Posted October 24, 2013 Author Report Share Posted October 24, 2013 I want to get the car back to a original condition car (or as close as I can). The Weber’s on my car will cause me to fail the smog check and in my opinion look out of place in the engine bay, so I need to make the change. Quote Link to post Share on other sites
Andy Moltu Posted October 25, 2013 Report Share Posted October 25, 2013 Weren't they on Strombergs originally? Did it fail the smog test previously or did you buy it from a different State? Quote Link to post Share on other sites

You could go with Webers, but it would cost way more than refurbing a PI set up. Quote Link to post Share on other sites
RobinTR6 Posted October 25, 2013 Report Share Posted October 25, 2013 Amusingly I have a set of Strombergs, the full PI kit (at last), now just need to lay my hands on a dizzy for the PI as the ones I've got are for carbs. The PI kit needs a complete rebuild pump, MU, injectors PRV. I was considering slapping on the Strombergs (also have the inlet and linkage for them) as they are in the garage; then getting the gearbox,axle, engine back together , wiring etc etc just to get it running and then decide which way to go. The engine was rebuilt 10 years ago and was an American CF engine, apparently lightened and balanced, new flywheel and clutch, its alsohad a PI head put on it .....but never run.....hence my quandary..... Happily the chassis is like new and the dry state body is rust free, suspension and brakes all rebuilt and new as well. Quote Link to post Share on other sites
bobrogg Posted October 25, 2013 Author Report Share Posted October 25, 2013 I have no issues with using Weber carbs but when I bought my car I had intended to restore the car to a original configuration. One item that does bother me is in order to install the Weber's you will need to hammer on the front right wheel well to make room and make some accommodations for emissions equipment pluming Quote Link to post Share on other sites
stuart Posted October 25, 2013 Report Share Posted October 25, 2013 If yours is a late car then you should have the full length depression on the arch anyway so the Webers should fit with the correct choice of air filters.(FWIW they will fit the earlier half depression anyway.)

Tom Fremont Posted October 25, 2013 Report Share Posted October 25, 2013 I thought '75 and prior TR6s were exempt from CA smog tests - maybe you could set the record straight, Bob . As for the carbs themselves, Webers will run at least as clean as S.U.s or Strombergs when calibrated optimally. The factory Strombergs will have the necessary connections for the emissions equipment however. I don't know what a P.I. refurb costs, but maybe Bob will give you a deal on his Webers, Robin . A guy local to me recently got a set of vintage Italians with manifold for under $300. I'm partial to these myself, and have done over 100K miles on a very old set I got for $200 ( sans manifold though ) in 1994, cleaned but never rebuilt. Quote Link to post Share on other sites

My car is a 1976 which does require smog testing, 1975 and back does not require smog testing as of now but there was a rumor that even this will change and all gas powered autos will require smog testing of some type here in California.

RobinTR6 Posted November 1, 2013 Report Share Posted November 1, 2013 Bob, still interested in your Webers so let me know if, when you change, thanks Quote Link to post Share on other sites
stuart Posted November 1, 2013 Report Share Posted November 1, 2013 Bob, still interested in your Webers so let me know if, when you change, thanks Robin I think you may find that they are twin downdraught ones, quite a common conversion in the US. Stuart. Quote Link to post Share on other sites
RobinTR6 Posted November 1, 2013 Report Share Posted November 1, 2013 (edited) Well spotted that man, Ok will wait to hear more. Just to clarify I'm after some (3) ie triple Weber DCOE 40 151 (side draft) Edited November 1, 2013 by RobinTR6 Quote Link to post Share on other sites

bobrogg Posted November 1, 2013 Author Report Share Posted November 1, 2013 (edited) What a difference the SU's Stromberg's have made. The TR6 runs in a much more civilized manner now and performance difference is night and day. I'm very happy with the change and I honestly think my TR6 has gone from a grumpy old man back to a happy middle aged runner. Now on to the drivetrain repairs Edited November 1, 2013 by bobrogg Quote Link to post Share on other sites
