E30 vs E28 på bane..

[marius paulsen]

eller tydligvis en annen billøpsklasse

[325e]

e30 m3 tok over for 635, så de kjørte nok i samme klasse.

Vet også at Volvo 240 kjørte i samme klasse som både 635 og m3.

Og av en eller annen grunn greide BMW å få disket Volvo pga at de mente de kjørte med for høyt motorvolum.

Litt merkelig når volvo hadde 2,1T (x1,4=2,94L), og BMW selv hadde 3,5L.

[S14]

Etter alt av hva jeg har lest om BMW M3 E30 ble den laget med rekke 4'er pga at med 6'er ville den blitt for fremtung, de ville ha en motor som klarte høye turtall og de andre tingene som er nevnt. Sesongen 87 og 88 deltok M3 E30 Gruppe A bilen i hvertfall to-tre standardbilturneringer.. VM, EM og det tyske (Også kalt "gamle" DTM). I 88 ble VM turneringen borte og EM turneringen ble borte den også (i 89 tror jeg). Deretter har den tyske standardbil mesterskapet het DTM. Og av det jeg har lest har det aldri stått noe om at BMW M3 E30 hadde rekke 4'er pga regler i DTM (eller de andre standardvogn mesterskapene).. Audi's V8 Quattro deltok også i DTM, som en "direkte" konkurrent til M3 E30..

[Espen M33]

Tydelig at noen har misforstått kraftig her. Ja, M3 ble bygd for å delta i DTM. og for å delta i DTM så måtte det bygges minimum 5.000 eksemplarer av bilen for gatebruk. 4 eller 6 sylindre hadde da absolutt ingen innvirkning på dette. Men M Gmbh lagde jo, som det viste seg, en perfekt bil. At de brukte en motorkonstruksjon fra 60 tallet(ikke sikker på hva den motoren heter) ser jo ut til å ha vært et bra valg, for S14 er sterk. Faktisk tror jeg ikke det finnest dens make om man sammenligner med dens reelle konkurenter. Så Paulsen, bit i deg de ordene om at jeg tok feil

[Gunnar]

Faktisk tror jeg ikke det finnest dens make om man sammenligner med dens reelle konkurenter.

Ikke fra de tidene, men Honda har jo slått S14 ganske grundig med sin S2000 som har sine 240hk på en 2-liter sugefirer... Det er brukbart det!

Sånn litt på siden: Er det ikke forresten slik at 320is faktisk er en 2-liters S14? Den har vel høyere effektuttak enn de fleste E30 M3er.

Den har vel 192 hk orginalt..

[Gunnar]

Den har vel 192 hk orginalt..

Ja, det vet jeg. What's yer point?

[Espen M33]

Jepp. 320iS har en S14 B20 med 192Hk. Mener den har høyere komp enn storebrødrene, men ellers er det vist ikke mye forskjell. ja bortsett fra at den er levert uten katalysator da. Jeg har lenge hatt lyst på en sånn bil, men det er for det første vanskelig å finne et bra eksemplar fra 88, samt at det også er dyrt å ha 2 S- maskineri i drift. Har hørt rykter om at de bilene er rimelig friske.

[R Andersen]

espen m33: hva må man betale for en 320is?

finner man dem i tyskland, eller må man til italia?

finnes det noen i norge?

Så på et engelsk forum at de nevnte at bra eksemplarer var å finne fra £3.500 og oppover, altså ca. 50k og oppover.

Hehe. Tenkte på høyere effektuttak per liter. Manglet kanskje et par ord der.

[Espen M33]

Det står alltid noen eksemplarer på mobile.de Det er et par innflyttede italienere som importere dem til Tyskland. Problemet er som følger:

- Det må være en 88 mod for å få den godkjent i Norge(pga mangel på kat)

- De kommer fra Italia, og mangler i 98% av tilfellene alt av historikk, og det er heler ikke så enkelt å finne ut noe om man da ikke er en jævel på å prate italiensk.

Om man finner en ok bil, så havner den på 70-90Kpå veien i Norge. Da er man ikke sååå langt unna en M3, som tross alt er en helt annen bil. 320iS ble levert som en hvilken som helst 325i, bare at den hadde S14 motor, dogleg kasse og sperrediff. Det finnest faktisk til og med eksemplarer uten sportsinteriør, og med 14" stålfelger. Det vil si at den på langt nær har samme kjøreegenskaper som en M3. Men jeg kunne tenkt meg en likevell

History

What makes the E30 320is unique?

The E30 320is is a special 3 Series model that was sold exclusively in Italy and Portugal in order to take advantage of the reduced taxes in those countries for cars with engines that displace two liters or less. It is powered by a 1990cc version of the four-cylinder S14 engine developed by BMW Motorsport for the E30 M3 and also shares the M3's close-ratio gearbox. However, all other components are standard 3 Series items.

Where was the E30 320is built?

The E30 320is was built on the normal Regensberg assembly line alongside the other 3 Series models.

If the E30 320is is powered by an M engine, why is not badged as an M model?

The reason the E30 320is is not badged as an M model ultimately comes down to marketing: Unlike the limited-production M3, which was created primarily as a competition machine and utilizes many unique exterior body panels and chassis components, the 320is was never intended to be a homologation special. It was conceived instead as a sportier and more affordable alternative to the torquier and more refined 325i, which was taxed heavily in Italy and Portugal due to its 2.5-liter engine.

Production Data

How many versions of the E30 320is were developed?

BMW developed the E30 320is only in non-catalyst, left-hand drive form and exported it exclusively to Italy and Portugal. Both two-door and four-door body styles were offered.

Hoe many of each version were produced?

Two-door: 2,540 built from 11/87 thru 11/90

Four-door: 1,206 built from 09/87 thru 07/90

What changed during the production of the E30 320is?

There were no mechanical changes to the E30 320is during the three years that it was produced. However, there were a number of minor cosmetic and equipment variations that also apply to every E30 3 Series model built during the same period.

Drivetrain

What makes the two-liter S14 engine unique?

The two-liter S14 engine in the E30 320is is essentially identical to the 2,302cc version found in the E30 M3 except for its shorter stroke (72.6mm versus 84mm) that yields an overall displacement of 1,990cc. Like all S14 engines, it combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments.

The two-liter S14 is rated at 192 hp (DIN) at 6,900 rpm and 155 lb/ft of torque at 4,900 rpm. This is down slightly compared to the non-catalyst, 2.3-liter S14 used in the E30 M3 which is rated at 200 hp (DIN) at 6,750 and 176 lb/ft of torque at 4,750 rpm.

The S14 engine fitted to the 320is has an identical appearance to the unit found in the E30 M3 and thus shares the "BMW M Power" inscription on its cam cover.

What kind of gearbox does the E30 320is have?

Like the European-spec E30 M3, the sole gearbox for the E30 320is is a close-ratio Getrag 260 five-speed manual with a "dogleg" shift pattern and the following ratios: 3.72 (1), 2.40 (2), 1.77 (3), 1.26 (4), 1.00 (5). This is mated to a shorter (compared to the M3) 3.46:1 rear axle ratio with limited-slip differential.

Chassis

How is the suspension of the E30 320is different from that of a standard E30 3 Series?

Like all E30 3 Series, the suspension of the 320is consists of a MacPherson strut/semi-trailing arm design. However, the springs, shocks and anti-roll bars are of the more aggressive "Sportfahrwerk" specification, also offered on other E30 models such as the UK-spec 325i Sport.

What kind of steering does the E30 320is have?

The 320is uses the standard E30 power-assisted rack-and-pinion steering system with an overall ratio of 20.5:1.

What size brakes does the E30 320is have?

The E30 320is shares its braking system with the six-cylinder E30 models and thus is equipped with 10.2-inch (260mm) vented disc brakes in the front and 10.2-inch (260mm) solid disc brakes in the rear. ABS was fitted as standard equipment.

What are the factory wheel and tire sizes for the E30 320is?

The E30 320is is equipped exclusively with 195/65VR14 tires. These are mounted to one of two different alloy wheel designs, both of which were shared with other E30 3 Series models: The 6.5x14-inch cross-spoke wheel (standard on the two-door) or the more plain 6x14-inch alloy (standard on the four-door).

Cosmetics

How is the exterior of the E30 320is different from that of a regular 3 Series?

The exterior of the 320is can only be identified from other E30 3 Series models by its "320is" badging on the trunk lid, though this could be deleted upon request. (The curved dual exhaust tips are also unlike those of any other four-cylinder 3 Series but are shared with the six-cylinder E30 325i.)

What items were fitted as standard equipment to the exterior of the E30 320is?

The exterior of the four-door E30 320is is equipped only with fog lights, 14-inch alloy wheels and a body-color rear spoiler. The two-door version adds the complete M-Technic II aero package (identical to the one fitted to the UK-spec 325i Sport and available as an accessory on all other E30 3 Series models), which consists of a deeper front airdam, additional lower side body panels, an extended valance under the rear bumper and a two-piece rear spoiler. In addition, the two-door E30 320is is also equipped with body-color rearview mirror housings, Shadowline (dechromed) window trim and 14-inch cross-spoke alloy wheels for a sportier appearance.

How is the interior of the E30 320is different from that of a regular 3 Series?

The interior of the E30 320is is identical to that of other 3 Series models with the sole excpetion of its unique instrument cluster that utilizes the same tachometer with integrated oil temperature gauge as the E30 M3, but lacks the M3's red needles and M logo between the two main dials. Also, the gear shift knob is of the older non-ergonomic design that was phased out on other E30 3 Series models (with the exception of the M3) in September, 1987.

What interior features were included as standard equipment on the E30 320is?

The interior of the four-door E30 320is is quite Spartan, offering only the basics such as power mirrors, central locking and a rear-window defroster as standard equipment. The two-door model adds map lights in the rear view mirror, sport seats, a three-spoke leather-wrapped M-Technic steering wheel and a leather shift knob.

Factory options for both two-door and four-door versions of the 320is included: air conditioning, power windows, manual sunroof, power sunroof, digital clock, on-board computer and leather upholstery.

Special Versions

Were there any special editions of the E30 320is?

There were no factory special editions of the E30 320is.

ja, jeg fikk litt lyst på en selv.

var i italia i fjor, og de var ikke så nøye med bilene sine nei..

selv spesielle biler ble behandlet som dritt..

har ikke is samme understell som M3? dvs 5-bolt.

Italienerne har helt klart et annet forhold til bilene sine enn en gjennomsnittlig tysker. Så skulle jeg kjøpt en italiabil så skulle jeg brukt flere timer på å gå igjennom tilstanden denns..Noe man selvfølgelig uansett bør gjøre da, men et par timer ekstra for en italiener.

320Is har vanlig E30 understell, altså 4x100 boltsirkel. Eksakt samme understell og bremser som 325i og 318iS.
