Hartge H36 Project (E30 M3 with S38 M5 engine)

[bss325i]

Slap me for being stupid, but i thought this engine was factory fitted to this car? So there shouldn't be any clearance issues?

Check out pages 3 and 6 for some of the bulkhead action by Hartge to fit the donk!

it was factory fitted to an M5 , it's a bit of a juggle/squeeze to pop it into an M3 shell but no doubt Theo will manage it...

Epic chariot this, shame he won't sell me it !

[Dezzy]

Steve there cant be many E30's that havent be through your mits

[Theo]

According to Hartge, MC Hammer was in charge of their 'Big Six' e30 conversions

[Simon13]

can't touch this

[staley_turbo]

Sorry forgot it was a new shell. I find it surprising sometimes to find out how the factory bodges things. All in the best of hart though!

[Theo]

Yeah, I think everyone was surprised to see how bad the bulkhead was. The chassis rail which had been reduced in thickness to allow fitment of a standard e28 m5 air filter housing was even worse though!

Just tried the M3 and M5 servos in place to get an idea of any fitment issues there might be with either version. As you can see, the M5 version places the fluid reservoir right in the way of inlet of the plenum. Not a real problem as I could easily fit a remote reservoir. The M3 version fits ok and gives about 13mm clearance to the plenum. Saying this, I to think the offside of the engine needs raising which will push the plenum closer to the servo - will have to take another look once I've wrestled the engine into the correct position.

[DanThe]

That twin servo will make a lot of difference to the brakes, id be using that with a remote res

[e21Jason]

How about the e24/28 hydraulic servo

Jason

[staley_turbo]

The e28 sytem isn't very good and is a alot of work to fit.

[Theo]

No it's going to be one of these two Jason, probably the M5 version as it makes sense to me to effectively have a complete e34 m5 brake system on the car.

I can use proper BMW parts for the remote reservoir conversion, I'd just need to make a bracket for it.

1x 34321112399 brakefluid reservoir (2002Tii)

2x 34321102282 brake pipe elbows to go into grommets in the mastercylinder

2x 34311121911 o-ring (grommets) for the mastercylinder. These have a smaller inner diameter hole than existing ones so that the elbows can fit snuggly

1x 21521163714 cloth braided hose from elbows to reservoir

[gareth]

Is that similar to the 325ix servo?
I've often wondered about fitting one of those

[Theo]

Yeah it's the same part number as a 325ix servo, different master cylinder though.

[DanThe]

They are the same as fitted to E34 tourings, ive sent a couple of these abroad destined for an E30 brake upgrade

[gareth]

cool

I've wanted to try one of these for a while, partly for the novelty value and partly to give a bit more room around the heater hoses etc

[staley_turbo]

You have more room than me!

[Theo]

That's a squeeze!

After more faffing around manipulating the anchor into the correct position I'm coming to the conclusion that neither servo is really viable with a standard plenum, so looks like I'll stick with the original modified plenum with M3 servo and master cylinder.

One last option would be to consider a clio servo as used in various engine conversions. Anyone got the measurements for one of these? A pic would be good too please.

[DanThe]

Using one on mine with the same brakes and a 750i MC
190mm ish rings a bell....

[Theo]

As small as that? That would definitely work (famous last words) my M5 servo is approximately 250mm and the M3 servo 270mm.

[staley_turbo]

Thats a clio servo in the pic above

[Theo]

Is it a straight fit or is molestation required?

I suppose your plenum is further over because you have a fairly thick adaptor plate between the M30 head and the throttle bodies?

[staley_turbo]

Its pretty much a straight fit and yes the plate is about 20mm thick. But even with the smaller servo, the plenum has had to be modified and the heater matrix pipes are very tight.

[Rav335uk]

Which clio servo is that Staley??
Plastic winged or older?

[staley_turbo]

Plastic winged i think. Was i while ago

[Kos]

you cant put a clio servo on this car

[e30topless]

you cant put a clio servo on this car

absofuckinglutelynot !

i would rather have no brakes than renault parts on an epic chariot like this !

[Theo]

Don't get your knickers in a twist ladies, it's only a brake servo! I'd argue that an unmolested inlet plenum (which is a tuned component of the intake system) is preferable to an original brake servo.

Saying that, I'm very lazy and the thought of wrestling with a clio brake servo in a muddy scrapyard doesn't really appeal. I'll probably do something else on the car and return to this quandary at a later date.

[Dezzy]

Fooking hell I thought there was going to be an update.

Bollox!

[Theo]

Sorry Desmond

I have arranged to get a custom radiator made for it, it's working out only £50 dearer than a new radiator from BMW and will be more efficient. Same fitment as the standard rad but with a thicker twin core.

[Dezzy]

I was just thinking today how it's was coming on.

[Theo]

I replaced one of the heated mirrors the other day, the old one was open circuit.


I also spent fecking ages going through the wiring and came to the conclusion that Hartge didn't have a fucking clue. Except for the speed limiter removal device - that was done nicely 274km/h crash here I come.

[Dezzy]

What a way to go.
