Has anyone tried to contact DA lately? Because I have been sending them emails for a week now with no reply... I live in Spain, and a call overseas might be kindda expensive.If someone could call them to ask if they sell it for the E30, I would really appretiate it. I want to buy a kit for my E30, does anyone know if it�s allready available?
Thanks a lot guys.

no they dont do one not the the e30 m42, they do one for the e36 though, however i am not positive on these conclusions.

the downing e36 kit WILL fit the e30 grassroots did it.

doesn't their add in Bimmer and Roundel show a e30 m42? I was under the impression that I had read they built one for the e30 m42.

Not only did they build a kit for the E30 M42, it was detailed in Grassroots Motorsports in 3 or 4 issues last summer and discussed / copied on this very site! Let's stick with the facts hombres.

Shocker has a Supercharger on his E30, but I'm not sure if its DA or not.

That looks like a custom set up rather than the DASC...

thanks guys. what grassroots did was modify the kit form the e36, the biggest problem they had was the serpentine belt system versus the v-belt system on the e30. I have a full system of serpentine belt system, taken out of an e36. so I should not have a problem with that. But my main problem would be not having knocking sensors as the e36. I also know that the DASC leaves a lean mixture on the engine. So if I improve the mixture through remapping, would I still have knocking?
By the way, DA website is not working for me since last night, does it work for you?
http://www.understeer.com sells a diferent supercharger system than DA, that�s the system on the picture above.

That looks like a standard belt on the s/c pulley?

Yes it is. If done correctly it works fine.

this is an eaton m52 s'charger, used on 2.0-3.0 litre engines. i have an eaton m40 s'charger from the MINI Cooper S sitting in my shed that i was gonna use

this one in the pic, does not seem to have any intercooler. if i had a 'charged engine, i would want to use an IC. maybe this guy is using laminova's?

I would like Shocker to write his opinion on his kit, and if he has had any detonation problems.
An intercooler would be way too difficult to install on a supercharger system, due to the limited space and the position of the manifold. besides a supercharger only raises the intake temperature by 60-70F compared to a turbo is nothing.

Well since you will never find someone to make this kit id say go with the Downing Atlanta Kit, then all you have to do is swap over to the e36 pulley system and get a remote brake reservoir from the 2002 which I have on my car and whatever else GRM did. As for detonation I have an audible knock sensor on my engine so I know when it happens. I’m running stock timing right now but I’m running 100 LL octane only because I can get it cheaper then 92. (My dad has an airplane) but I do need Adjustable timing because I won’t boost past the middle of 4th gear it starts knocking at 12PSI on stock motor.
