Лёха пипец... Нет механичестих реек Е36...

Бочка с медным кольцом? Судя по надписи - ограничитель высокого давления

Зато появились стеклоподъёмники

The goal of this conversion is to reduce the steering ratio. The E36 rack has a faster rack ratio - the rack moves a greater distance for a given angular rotation of the input pinion shaft. Since the "installation ratio" is the same (same subframe and steering arms) then the net result is a faster overall steering ratio - 24% quicker, in fact, with the E36 M3 rack. Note that using "number of turns lock-to-lock" is not a very useful way to compare steering ratios, as the length of the rack, as well as its installation, can and do change the # of turns lock-to-lock (from car to car) - with no change whatsoever to the actual steering ratio. The results of using a 1995 E36 M3 steering rack in an E30 M3 are summarized in the following table:

Steering Rack Type  Rack Ratio
(mm/rev)  Steering Ratio
(deg/deg) 
E30 M3 w/ stock rack 38.0  19.6 : 1  
E30 M3 w/ 1995 E36 M3 rack 47.0  14.9 : 1 
 
The E36 M3 rack housing is aluminum, whereas my E30 M3 rack housing was steel. The aluminum housing might offer better cooling - it is tough to know for sure. (Don Fields from Mr M-Car notes that many E30 M3's came from the factory with aluminum rack housings, perhaps mine was an early version). The two racks were not weighed for this article, but any difference in mass is not likely to be large (a qualitative assessment). One can see a difference in the angle at which the pinion enters the two different rack housings. This difference causes greater angularity in the joints in the steering coupler when using the E36 M3 rack in an E30 chassis. The coupler joints hence require modification to prevent them from binding up. Zionsville provides a modified coupler as part of their E36 M3 rack conversion kit.

The steering rack swap gave me the excuse to do something I've wanted to do for some time. I made an aluminum spacer ring to replace the rubber steering Guibo that all BMW's seem to have. My old 1976 Rabbit did not have any rubber in the steering system, and I had always enjoyed the direct steering feel such a setup offered. The steering Guibo is intended to absorb kickback through the steering wheel - a job it does quite well. Unfortunately it comes at a price of reduced feel and communication. The aluminum replacement is quite easy to make and install at this point, since the coupler is out of the car. The difference is not huge, it's just one of the many little things that go into making a car feel great, instead of just good.

Note: Don Fields from Mr M-Car points out that the modifications to the steering coupler shown above, namely the solid Guibo and the bolts used to lengthen the coupler, both reduce the ability of the steering column to telescopically collapse in an accident. I drive with a roll bar and a 6-point harness, and I make a conscious decision to accept this change to the steering column. Make sure you think about it too, should you decide to follow suit.

The steering rack swap was also a good time to upgrade all the hoses in the system, especially the high pressure hose, of which the factory version is prone to failure. I modified the factory metal lines by welding on AN fittings. The lines were subsequently Gold-Cad plated to prevent rusting around the weld joints. All the lines in the system (including the high pressure side) are AN-6, except for the return line from the reservoir to the PS pump, which is AN-10. These are all common sizes for a power steering system. 
All the low pressure lines are Goodridge G-Line XF 910 (Aramid) with crimp-on connectors, the (very short) high pressure line is Aeroquip Kevlar braid. The XF 910 is pretty cool stuff, though a bit expensive. But it is incredibly light, and if you were plumbing a whole car with this you would really save some weight, though you'd put a big hole in your wallet too. We'll see about durability.

The AN-type hoses required a new power steering fluid reservoir which was sourced from AFCO .

No power steering system is complete without a cooler, so one of these was plumbed into the return line from the rack to the reservoir (this is the traditional location for a PS cooler). The best place to locate the cooler, from the point of view of getting good airflow across it, is up near the front of the car, in front of, or next to the radiator. However, I wanted to find another location where cooling airflow would be sufficient, yet there would not be a need to let more air through the front of the car, or impede the airflow to the radiator. 
The location I chose for the cooler is just above the driver's side front control arm "lollipop". There is enough room, there is a good flow of relatively cool air under the car, and the plumbing is fairly convenient. The air will not flow through the cooler in the optimum orientation (i.e. directly through the fins) but convective cooling will still occur. There is the possibility of debris being kicked up from the tire and damaging the cooler, but so far this has not been a problem. The lowest part of the cooler is still above the lowest part of the frame rail.

The factory power steering high pressure restrictor was not used, nor was a duplicate version plumbed into the system. There are no apparent down-sides from leaving it out. No increase in noise, and no loss of performance.

This photo shows the layout of the power steering lines and the power steering reservoir from above. 
Note that the stock power steering pump was retained. It is quite light and as long as it provides enough pressure and volume to the rack, I saw no need to swap it out. 
 
The 1995 E36 M3 steering rack requires spacers in order to fit into the E30 front subframe. In principle this allows the steering rack to be moved up and down to adjust bump-steer. Zionsville provides spacers with their conversion kit. I have used these for now, and placed them above the E36 M3 rack, which puts the center-line of the E36 rack in the same position as that of the old E30 M3 rack. In the future it might be usefull to make sets of spacers that allow the rack to be shifted upwards in an effort to improve bump steer.

Вот собственно....интересует - что за деталюшка круглая? и вон показана переделка крестовины, как и обещалось..

Макс, так ничего и не слышно?

Дык новую тебе и не предлагают... ;-)

SharkX · Answer

дороговато :) надо бу адназначна!

Classic car® · Answer

Стеклоподъёмники там разлетаются как горячие пирожки. Механическая рейка в ЕТК есть. 
Новая стоит что-то около 350Евро (точно щас не помню).

SharkX · Answer

нет? Макс! мне же 2 а не четырее нада :) неужто в Немеции нету?

Я вот по ЕТК тоже не могу пробить - везде с гуром идёт 36 кузов... Чего там ишшо нада подкупить для установки с ГУРом? но я б предпочёл без оного... 
Какие цены то там будут с доставкой на родину?

Classic car® · Answer

Стеклоподъёмников пока. 
Про рейку: бургеры очень удивляются, что нужна механическая рейка, а не ГУР. Грят давно не было. С ГУР навалом... Будем ишшо искать....

Завтра гляну. 
Но стеклоподъёмники с проводкой  - редкость. Но всё равно гляну...Вдруг повезёт... ;-)
