Sure they do, Im not familiar with the terminology as they use a number of different ways to express hardness. Its like buying a good knife, Rockwell tells you little about the character of a blade. See https://www.powerflexusa.com/how-to-choose

I have Powerflex all around and if I had to do it again I wouldn't put poly everywhere. Its not loud though, it just transmits too much. I have a healthy diff, but with the poly I hear it. It is however super tight, if any joint goes south you notice it immediately.

Yes would be nice to have a tire rack in the garage, but it always comes down to how much mileage you cover each year and I like to drive with tires that are always <= 6 years from date of manufacture.... I suspect that a lot of FAQers who don't use their cars as a daily driver have the problem that their tires are old since they do not cover enough miles each year. For a homecoming queen, shoes don't matter as she does not need to walk...just like a museum piece or a trailered show car does not need to drive... I had two sets of tires for a while, a set of XAS for rallies on mixed surfaces and the A021Rs for the track...but that was kind of iffy, good thing the XAS wore out 123. I only have one 2002, tires for the rest of the fleet are non-interchangeable.

Insight on the Avons would be interesting, I bought the Pirelli's because I could not really find much feedback on the Avon's. I went from the A021R to XAS and the Pirellis go on next week...Summer tires are street legal here after 1. APRIL...

The AD21R are rain tires, they used to be E marked and therefor street legal. @gazm3, when did you buy them? They used to be used in the Caterham cup series in the UK, nice tire but I was told they were discontinued...can you confirm they are available? They are very soft, I don't think I got 3k out of them. Andrew

Toby's answer is on the money, though 9.5 is in my view really low for a 304 and 45's...at least at low RPM where you shouldnt be anyway. If your looking for torque at low RPM, stock is the way to go. Just doesn't have the visual and audible effect. Or the 292 with small chokes if it will never go over 5000 anyway... Andrew

From the threads, the ti/tii manifold is considered pretty good...headers wont bring much other than heat and noise unless you modify heavily and the engine needs to breath a lot more. A lot depends on what you put after it as well. I have a polished, ported and skimmed head with a 300 degree cam and 45 dcoes with the stock manifold and a free breathing exhaust behind it. I have no empirical evidence either way. If I had the ti manifold and heat shield, I would stick with it. As dp wrote, I wouldn't pay an arm or a leg for one either. Maybe someday one will show up for reasonable money if you search. Yours came exhaust free?

I have a facett pump and king filter, never have experienced starvation with the DCOEs and I was also running A021Rs on track days... It would have to be a really long bend (I would think) to move the fuel in the tank so far, have the pick up tube and pump run empty, have the King filter fuel bowl run empty, the pipe through the chassis run empty and the sizable DCOE bowls run empty... Maybe your floats are at a minimum anyway and the corners exacerbate the issue? andrew

My 2002ti turns 50 today, built on Monday the 8th of February and delivered to a German dealership on the 9th of February according to the archives. I sometimes call her Heidi, but sometimes not as that was also the name of my first BMW. The pictures I took at purchase are on slides and I could not really scan them properly...but she was on the road from 1971 to 1980 and then parked until 2007. I purchased her in June of 2000, the trunk was full of good bits but the engine bay was empty, seats gone with square taillights…but came with all of the pieces to retrofit to original condition. Chrome was good but old. A few pictures to show the journey taken from rolling body and pile of parts to a somewhat presentable 2002ti that still gets regularly exercised. Poor quality picture as purchased in 2000 Bodywork and painting was finished by 2003 Engine came together thereafter, got a nice heavily ported head with a 300 degree cam in ebay... Somehow, I put it together but it took me 2 years from "putting it together" to get it so far that the German TUV inspector would also be happy. Lots of stress with the carbs, ignition and other things that just took time to iron out. First picture is as assembled, second is after successful registration. Here in 2010 at a local event Five years later... People like keys... Also from 2015 One shot from a track day in 2020, only had a few events last year... Hopefully this "anniversary" year will be a better one than 2020, first track day is 13. April... I assume we will get lots of anniversaries in the coming years, I hope you guys will also share the journey. Andrew

You have big plans, I am kind of am stuck in the "use it until it gets really tatty"...after 20 years, the paint job I did (which was ok, not great, no orange peel) is now getting tired. If I go for a full restore, might not want to drive it on gravel and at events...hmm. She turns 50 in 2 days, so I will post some pics. This year is only minor suspension and tuning updates. I have some new sport springs to replace the HD OEM springs and a new set of CN36's to mount in the the spring. Last thing is finally hook up the AFR, get rid of the stumble at 1800 rpm and put it on the dyno. Dyno is probably the toughest one, always some reason to put it off.... Andrew

I'm if they have the square pattern and chaulky grey rubber color...a childhood memory. A.

Blaupunkt has reissued the globes for the rear parcel shelf...not oem but old school. I was thinking of making mounts for the Bose Revolve + which can be paired, because then you can move them from car to car if you have other cars where you want good sound without investing in the car itself. Have not found a good 1/4 UNC mount to use yet. The oem mono radio is a bit of a drag. Andrew

Those are a different variation on a theme...the ones I had in eurospec E12, E21 and E30 all had the square ribbed pattern and had the bmw logo molded in (not raised or visible, just on the edge somewhere) with model numbers and part number as well...never had a set for the 2002 unfortunately. I would be interested in the square ribbed variant... Andrew

That's why I secured my user name here and on ebay...because I was living in Germany at the time. Andrew

Hi, I would not start swapping the chokes/venturis, too large a choke with a weak mix will produce poor performance...but if you don't know what your mix is, better to tinker with the distributor...You said it ran well initially, the choke itself is not likely to be a problem alone. If its not properly seated, that is a different issue. This is like a table cloth, just pulling on one corner won't make it fit the table better necessarily... Andrew

Yes, filters are good...but every once in a while its great to hear the engine breath deeply....just for fun. The roads here are too dusty to drive without filters ...let us know how it turns out. Andrew

Hi, Well, from an efficiency perspective yes, but do you want the electronics that go with it? When you find the right setup, the webers are fine and give a classic look....sound good too without the air filter. Trouble is, you fiddle to get the right setup. There are lots of posts here to help you. The electronic injection path will either work great, or not all. While the dcoe path has a lot of space in between good and not working at all. I have a preference for the 123 distributor with the weber, you have more flexibility to adjust it to suit your engine. Do read through the posts on how people have done this, will save time getting to "good". Andrew

Hi, If you are running the stock 2002 distributor with vacuum advance, its probably suboptimal if you have the higher compression pistons, cam and carbs. The ti's curve is different and a modified ti would be also different. There are posts here on FAQ with the curves so you might want to compare what your distributor has with these. If you are running 98 octane (NL license plates?), you can get a lot more advance without detonation. Andrew

I never mounted the Solex's, went directly to 45dcoe and the Solexs went to the shelf along with the bosch distributor.....the webers came with the car, but had lots of little issues.... Andrew

Hi, Are the Webers new? The distributor might be the cause, but this should have been a problem with the previous carbs as well ... Have you moved to the non-vacuum type distributor that the TI uses and does it produce an appropriate curve? From the first picture I seem to see a vacuum unit. In the later picture the distributor is cut off. If you did go with used carbs, the components are interesting but also all of the seals and o-rings. I had a lot of idle issues due to vacuum leaks (hose going to brake booster... and the various covers with o-rings on the carbs themselves). It took a while to get a proper idle even though otherwise I was getting good performance. Andrew

@hans, in some weber tuning guides they use a 4 cylinder pinto as the reference. Not sure why, but that's the starting reference for 4-cylinder 2-liter applications.... one of my books has this too. Andrew

The certificate may be a total waste in the US, but it helps in some countries in at least two areas: 1) historic vehicle certification - if you have to prove the authenticity of the vehicle to the agency that issues historic plates, "old" is not enough... no certification, no plate, no 100% discount on road tax and registration fees...a few hundred bucks a year... 2) insurer/appraiser - good to have when the appraiser knows little/nothing about 02s and you want to convey originality and get a good valuation....they then take the valuation from one of the market sources because the car is positively identified. Point 1 already returns the cost of the certificate three times over, not sure a printed email would have the same effect.... Andrew

@slavs...do you run the ti/tii or normal calipers? I have issues with the balancing weights rubbing on the calipers in front, I run the cosmic mk 2 which I would assume has the same offset(?). My tire guy doesnt carry the clip on weights that scratch the rims, but I always have issues getting the tire guys to place the weights so that the calipers dont remove them. Andrew

Difficult to say definitively, but ET28 is pretty good but tire size is also a determining factor.... 205/60 is unlikely to fit. 185/70 on a 6 inch rim is quite tight. Andrew

Hmm, doesn't exactly look like my Webers either....much nicer... Andrew
