E30 Zone

Hey Si, good to see this one is finally done! Havent been around E30's for a while - decided to check out the zone again and noticed your updated thread. Are you happy with the result? I still remember how fun mine was as a 2 litre.

We are building a fully striped out track car with a worked Alpina Group A spec M30 engine in it, but unfortunately not being finished I cant advise you on how it goes on track, but if had an M3 with an S14 in it I dought whether I would be swapping it out for an M30 - different story replacing an M...

BMW won a few European Touring Car Championships in the '70's and '80's with the M30 powered E24 (2 valve head) so they must have good potential as a track engine. Just an interesting side point.

awesome mate!!!! i have dreams about a 335i daily driver. My 335i is a dream to live with as a daily driver and still get reasonable fuel economy. I can thoroughly recommend it. By the way I like your colour scheme (if that is you car in your avatar). winkeye Good to hear you are getting close to h...

Thinking of a turbo now for my M30 converted E30. Thought it would be helpful to me and others to get a shopping list of the needed components from others who have done it. Any advice?

TCCA Motorsports in Sydney sell the Reiger kits and most of the German brands. http://www.tccamotorsport.com.au/

I guess you meant 3.5 M30. I have to put a plug in for the M30 over the M50.
Same weight, more power, more torque and cheaper to modify.

Did you have to use longer studs on the strut tops ?

Yes, I did.

thanks m10man, what size are your alloys buddy?

No problem - 7X16 with an offset of 25 - 225's on the back and 205's on the front.

here is the 60/40 kit with 20mm strut spacers in the front (so 40/40)

These are the spacers - they have a bmw stamp and part number on them - so must be available from bmw.

Mine runs just above the 1/4 mark when it's above 30mph and it will only go to just below 1/2 way mark in traffic, it won't go higher because i've set the fan switching on point at 97c. Is your ambient temp fairly high ? My wifes E36 runs at the 1/4 mark that is why I posted this querie. Ambient te...

It's the THREE red LEDs that are intriguing me. UK E30s only have one yellow and one red LED after the green ones. Do the red LEDs come on in sequence or all together?

The red LED's come on in sequence - so I suppose with all four glowing it is saying I REALLY NEED A SERVICE!!!

I have the 60/40 cup kit in mine with the M30 and found that is was a touch too low for practicality in a country area - so I put 20mm spacers in the front and now it sits 40/40. I can highly recommend the kit. Can take photos for you tomorrow. As far as the handling goes - the M30 does not affect i...

Thanks Brian, I just wanted to make sure it wasnt running too hot. The LED's are just the oil service due lights - I havent got around to resetting them.

M30 conversion guys - I am interested to know what temp yours runs at.
Mine runs a touch under halfway on the highways and dead on halfway around town.

I agree with Andy aswell - It all depends what your requirements are - but I will put my 2 cents in for the M30 3.5. It is so versatile - you can drive it around like a granny so easily and even just leave it in 5th if you like - but when the mood strikes you can plant your foot and enjoy all that s...

mine has a 3.91:1 diff at present which is amusing! i can do donuts in 3rd in the dry

i followed an e46 m3 off a roundabout....i was right up his arse to try and get him to floor it....he did and i was quite happy that i wasnt too far behind him in 2nd and 3rd he was pulling away but i think i surprised him in my crappy old touring Cool! :cool: I am lucky to be about 150kg or so lig...

This can only mean one thing (and a local engineer who I know well and who has built M30s before agreed), that my rattle was valves touching pistons! Damn you're LUCKY!! :eek: That is terrific news though that now it is right! Sounds like an adjustable cam gear is the go on the Schrick cam then - I...

Thats a great site Andy - would have saved me the headache of working it all out manually

It it good to hear your feedback about the 3.25 ratio also.. You're right nickso about 2nd and 3rd being awesome - just a smigeon behind an E46 M3 in the 60-80mph test in 3rd!

I have a chipped M30 (limiter at 6700 rpm, I think) with 205/50 x 15" tyres and a 3.73:1 diff and I want a longer ratio. My speedo shows 67mph at 3000 rpm in 5th gear. I keep going for 6th! And 1st is useless! I normally pull away in 2nd. It will still lay rubber pulling away in 2nd too, even with ...

Ok, I have just done the maths. This applies to a car (mine) that has 16 inch wheels with 225/45 tyres on the rear. With a 260/6 5 speed and a 3.46 ratio diff this is what you get in 2nd gear: 59.9mph (96.4km/h) @ 6400rpm. So with the stock limiter you dont reach 62mph or 100km/h. 63.6mph (102.3km/h...

I dont know the revs as I still cant get my tacho to work (reading too fast)

but I hit the limiter before reaching 100km/h. What is the limiter set at on the 535i?

I am using the E34 260/6 5 speed. The ratios are: 3.83, 2.2, 1.4, 1.0, .81. Once I get a chip that raises the limiter I should hit 100km/h in second just.

just while going slow, once i'm on the freeway i'm ok it stays about 1/4. but i just don't get why it would overheat if others aren't having this issue with just an electric fan and no heater. i filled the full system when the car was totally cold and waited till it was spilling out of the bleeder ...

Hey one more question for you guys. I have a 14" electric fan mounted as a pusher on the front of the radiator. This is a fan that claims 2950cfm of air flow. The car is still overheating in traffic even with the heater on full blast... shouldn't the 2950cfm be enough to cool the motor?? or do i ha...

I dont know if this has been covered yet or not but here goes - I have a 3.46 ratio in mine and it just feels like it needs another gear at highway cruising speeds and it doesnt quite get to 100km/h in 2nd gear. The guys in Germany reckon the 3.25 ration is the best - has anyone used a higher ratio ...

Thats one freakin big donk!

Looks mighty good though!

Is that the 286hp version?

Yeah, like I said in the email I would prefer to have the bigger box in - especially if you are thinking of turboing it. Let me know if and when you are serious about that as I know an M30 specialist in Sydney who knows what he is doing with M30 turbos. He has a couple of street registered Turbo E34...

I have G-Tech so will do the quarter with that and then next season will get up to the drag strip in Brisbane (Willobank) to get an official time. :cool: I havent done the g-tech yet as I havent got my tacho working properly. I have put the 6 cylinder plug into the tacho but it is still reading as a...

Thanks Andy - yes I am happy with those times as they are quicker than an E34 M5 and are on par with an E46 M3. My diff is a 3.46 LSD. The B6 in the test that I have used a ridiculous ratio of 2.79 with the dogleg box so 5th is 1:1 - not sure how to directly compare that with an overdrive box and my...

No problem mate. Looking forward to hearing how yours goes when it is all sorted

Korman BMW in the US. Here is the link http://www.kormanfastbmw.com/e34m30.htm

If you have put a custom cam in it just could be your cam timing. Did you have any amount shaved off your block or head? The E34 heads are very sensitive to having anything shaved off them - you may need an adjustable cam sprocket. Oh and by the way - do you get any sleep? Everytime I check on the z...

Nice one mate! That is obviously a 325e tacho - I would be getting myself an i tacho so I knew exactly where I am. I feel sorry for you blokes having to run cats too
