Advice pls. I have acquired a pair of hs6 from a b20 volvo that I plan to put in my 1970 b30, replacing the twin strombergs. <br>Any initial recommendations for springs and needles? <br>Andrew, Melbourne Aust.

Re: Swapping strombergs for SUs on 1970 164. (dadedo)

My car's EFI so I don't have a clue; however, the folks over at <A HREF="http://www.brickboard.com:80/RWD/?model=140-160" TARGET="_blank">Brickboard</A> are typically very knowledgeable on stuff like this. Good luck!

Re: Swapping strombergs for SUs on 1970 164. (R Salesman)

The '70 164 is THE best year for that model - fairly light and tons of torque.<p>You might consider sourcing a triple SU HS6 intake manifold as this was the way to go 30+ years back.<p>The early cars has twin SU HS6 carbs but their needles were chosen to produce 145hp and your car is capable of much more.<p>Below are some sites on SU needle selection, etc.<p>George Dill<p><A HREF="http://www.teglerizer.com/suneedledb/index.html" TARGET="_blank">http://www.teglerizer.com/suneedledb/index.html</A><p><A HREF="http://www.winsu.co.uk" TARGET="_blank">http://www.winsu.co.uk</A>/<p><A HREF="http://87.230.26.197/mediawiki/images/4/47/Needle_Types.pdf" TARGET="_blank">http://87.230.26.197/mediawiki...s.pdf</A><p><A HREF="http://www.classic-car-magazine.co.uk/articles/performance-tuning-su-carburetors.html" TARGET="_blank">http://www.classic-car-magazin....html</A><p><A HREF="http://www.lotuseuropa.org/images/WorkshopManual/Carb1.pdf" TARGET="_blank">http://www.lotuseuropa.org/ima...1.pdf</A><p><A HREF="http://www.su-stromberg.de/HTML/content/pages/index.php" TARGET="_blank">http://www.su-stromberg.de/HTM...x.php</A><p><A HREF="http://www.sw-em.com/su_carbs.htm#SU" TARGET="_blank">http://www.sw-em.com/su_carbs.htm#SU</A> carb applications<p><A HREF="http://www.sw-em.com/su_carbs.htm" TARGET="_blank">http://www.sw-em.com/su_carbs.htm</A><p><A HREF="http://cgi.ebay.ca/SU-Carb-Needles-AN-PAIR_W0QQitemZ310139770330QQcmdZViewItemQQssPageNameZRSS:B:SRCH:CA:101" TARGET="_blank">http://cgi.ebay.ca/SU-Carb-Nee...A:101</A><p>

Dear George - thank you for your detailed advice. I have never seen a triple carb manifold for the B30, but will start looking.<p>Regards Andrew Jackomos

Re: (dadedo)

Triple carbs ! <br>Some of the latter Jaguars had them.<br>There is something about the 3 carbs, due to the firing order of the Jag (which is the same as the B30) the center carb has a different needle than the other two. This is due the spacing between the intake strokes.<br>It makes the center one richer or leaner, I don't remember which.<br>From what I remember it didn't really make a big improvement in power.<p>Saw a MG four with four tiny SU's <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <br>Don't know if anyone ever made a triple two barrell sidedraft Weber setup for a B30 but they did for the MG.

Dear VolovBob _ Thank you for your advice as well. Much appreciated. The only triple manifold for the B30 I have seen for seen is the manifold for triple webers sold through KG Trimning. Be worth than the whole car!

Re: (gdill2)

George, I hate to say it but I am surpriseded that you would raise this issue as long as you have been working on Volvos.<br>The SUs (both HS6 and HIF6) and the Stromberg 175CD2 carbs all have the same mounting flange, JUST like on the B20, where they are also interchangeable (more or less). The trap is the secondary butterflies which CAN be used with the right arms on the HIF6 carbs but are better removed and the throttle shaft holes in the manifold plugged. The individual heat shields are required for ZS and HIF6 carbs where the HS6s need the one-piece heat shield. B30 carbs are spaced the same distance apart as B18/B20.<p>The likelihood of finding a usable manifold for 3 SIDEDRAFT carbs on a B30 is something greater than zero but not much. I've been looking for one for over 20 years. They were used on the AQ165 marine engine but most were the AQ170, basically the same engine with downdraft Solex 44s.<br>I did find ONE guy who has one and he sent me a pic of it but did not offer to part with it. The downdraft manifold will not clear the front exhaust passage on the B30E/F exhaust manifolds (I tried it) and I hear that it does not perform well in automotive use, possibly because of the marine carbs being better suited to constant speed operation. There is a guy named Dominik Benz that has a 69 or 70 164 with triple sidedraft carbs. The pix I have seen don't show the exhaust, but I hear that the car has "brutish torque". BTW I have contacted over 30 marine dealers asking about the manifold for sidedraft carbs on a B30/AQ165-70 engine and a few can remember seeing one but none have been able to locate one. A couple tried to send me a downdraft manifold but I demanded pix before sending money and confirmed what they were.

Hi there, I have a couple of 1970 164's, one manual overdrive and one auto. The manual has triple HS6 SU's on an alloy inlet manifold mated with the exhaust manifolds from a later efi B30. I can't remember the needles I used when I renovated the carbies back in the 90's but can check if you are interested. I plan to put all the good bits into one car eventually as the auto is in pretty good nick for it's age while the manual has spent too long in the open.

Re: (gdill2)

Hi George,<br>I took some pictures but had trouble loading them on the forum. When I click on the insert image I get this...
. If you are able to assist I will pop them up. The car has been sitting for some time so is not cleaned up by any stretch.<br>Thanks, Jim.

Re: Triple carb manifold (Walrus3)

OK Walrus3.<p>The story behind it is:<p>The first car I ever bought was the 1970 164 with M40 manual. Over the years I came across all the good bits like limited slip differential, M410 and the triple manifold with carbies. I came across the triple carbs and manifold back in 1991 when I was at uni. I used to drop into a little part time wrecker and chat to the two guys who ran it. One time they had the triple manifold and carbs hanging on a wall and while I wasn't that flush with cash as a student, as you could imagine I had to have this treaure. A price was duly negotiated and they came home with me. A full carb rebuild and purchase of the air filters was carried out prior to installation.<p>The car was absolutely sensational to drive and towards 1995 I was relocated interstate with work and while away the car was put off the road by Police while my brother was driving it. Into storage it went and has remained up to now - sometimes being a horder is a good character trait.<p>Last year I purchased a 1970 164 with Golde sunroof (alas auto) into which I plan to transplant all the interesting parts. I bought a set of rallye instruments (5 gauges) and a Moto lita steering wheel (I remember seeing one on the Repco 142R back in the 70's) to complete the project. I must say I am strangely growing fond of the old auto and big tiller at the moment but I still long for the manual.<p>If anything changes...<p>Regards, Jim.

Re: Triple carb manifold (164 nut)

Thanks, Jim.<br>I've had my 69 164 since I bought it in Panama in 1971, 2 years old, at half the price of a new one. Raised kids and grandkids in it and finally got it going (again, after a grandson dropped a valve into #2 cylinder on shutdown a couple years ago) on its 40th birthday. Trying to get some bodywork and paint done on it now at a less-than-disastrous (read, "less than 5 times what it will be worth after it's finished) cost.<br>Wish I could get a bonus on the use of parenthetical comments.....<br>(or even a discount!)

Re: Triple carb manifold (Walrus3)

That's a long association with one car. You are obviously a fan. Is it a manual? Does it have power steer? My original didn't have power steer or the fog lamps when I bought it. There must have been a few options to tick back in the day.<p>And, yeah, nice work on the parenthesis!<p>Jim.

Re: Triple carb manifold (164 nut)

It did originally have power steering, M400 tranny and 3.31 rear end.<br>At 204K miles it got noisy and I was afraid of crankshaft/rod problems so I swapped with a 72 FI engine. Later found out that the noise was a misfit timing gear and that there was only about 0.005" cylinder wear in the worst place, so probably timing gears and rings would have fixed it up.<br>Still using the original 2-carb manifold with HIF6 carbs (changed from HS6, changed from 175CD2s). A friend shipped me a set of fog lights from OZ, although the reflectors are pretty rusty. Hopefully it will look good before too long.

Re: Swapping strombergs for SUs on 1970 164. (dadedo)

Check this out: a conversion for Zenith-Strombergs to a TB fuel injection that looks stock.<p><A HREF="http://pattonmachine.com" TARGET="_blank">http://pattonmachine.com</A>/<p>Designed for a TR6, but no reason that it could not work on a 164--with the right mapping.<p>The prior owner of my TR6 replaced the Z-S with SU's and they run very nice, smoother.<p>If you have the cash triple Webers are always nice, but I think the dual throttle body will beat that.

A fuel rail can be fabricted for them and then you could use a latter Volvo FI system or go Megasquirt.

Re: Triple carb manifold (Walrus3)

Isn't a 3.31 an auto ratio? I had 3.71 in mine until the lsd lunched itself.<br>The old fibre timing gears are natorious for getting the death rattles - a set of steel gears is the go if you can locate some. Are HIF6 the under-bowl jobbies as opposed to the side bowls? I have a couple of those suckers in a cupboard. I was never a fan of the Stromberg 175CD2's as the mixture adust required a special tool to alter the jet height. SU's are heaps better.<br>Cheers,<br>Jim.
