im on it mate lol going to try doing it via the carb route,like the 5gt turbos.

Awesome, the carb route is apparently the best for big power. I want to do a turbo or supercharged m10 in the future
For parts I would highly reccomend jaymic, the specialise in m10's and really know there stuff!

might use a r5 turbo carb as i had a group n carb on mine,and they designed for use with turbo's.

Not meaning to cause any offense, but who on earth said that carbs are the best way to get power out of a turbocharged engine!?
They're not even all that good at getting power out of a N/A engine let alone something with far more complex fueling requirements
Cool project though!

On the m10 its apparently the best because the injection system isnt very good. I was told when I was looking into it that its either a stand alone custom injection system (really really expensive) or carbs for fueling.

my old r5 gt turbo was a carb turbo as they all were and mine would see off scoobys,cossies etc with ease. which is why i wanna use the carb route on my m10 lump.

I know it can be made to work, but things like drivability and economy etc. will never be as good as with a mappable ECU.
I understand what you're saying about the standard system not being all that good, but really and truely it's a bit of a bodge to use an N/A engine management for a pressurised application as the mapping requirements are so drastically different.
For example, it's perfectly acceptable to map an N/A engine on engine speed and throttle position alone. Throw a turbo into the equation and that's just not practical as the air flow into the engine is no longer directly related to the speed and throttle position.
However, give the system a means to measure the manifold pressure and you can generate a meaningful map again.
Just my two penneth

Anyway, Ԛ£750 will buy you a complete engine managemtn system and most of the sensors needed to make a really good job of it.
Just out of interest, what's controlling you ignition on this engine?

Theres no doubt at all on that one mate, im just passin what ive been told.
apparently the stock injection system cant flow enough fuel for a hot m10.

for my n/a beast im gonna be using a fully mappable system like the mega spark or emerald system.

i can get a piggy back ecu for management for 350 that covers all the fuel,boost etc

m4ddesigns tell me more dude
I am saving up for the emerald @ the mo, if your suggestion can bridge the gap in my fuelling until then all info gratefully recieved
turbo is ready to fit now, away for 2 weeks soon, want it running before then

its a custom piggy back ecu my friend makes his done 4 so far he got one on a escort mk5 rs2000 which he turbo'ed and now runs 246bhp at the wheels.he's a god of turbo's and all to do with turbo's.they use a golf vr6 ecu with custom and secret other parts.will be in production for any turbo car by the summer we hope lol

get him to mail me dude ant(AT)e30zone.co.uk
assuming hes using the golf MAP sensor and ecu with extra injector/s ??

will do do ant.its all very secret at the mo so no one nicks the set up and copyrights it.

mmm Turbo m10's
I'm also thinking of a turbo...my only concern is that all (*bar one) the m10's that I have seen turboed have been LHD. And there aint much room on the right.
Was there ever a 2002 turbo RHD, I don't think so only the conversion on
http://www.bmw2002turbo.nl/index.html
I have seen custom engine mount where the whole engine has benn twisted to the side, but not sure what that does to the gearbox linkage....
Any way some links
http://www.bimmers.com/02/upgrades/engine.html
and the is a link in the zone link sections (under engine conversions) that site has got loads of links on it.
Food for though...E46 diesel intercooler (long and thin) apperntly goes very nicely underneath an e30 radiator.....I saw one on ebay go for Ԛ£36 why i didn't buy it I don't know.
Keep me posted about all of this!

The best thing for a turbo M10 is to use something like Weber Marelli (Sierra Cosworth) engine management - a complete loom and ECU won't be too dear. It's a system that works extremely well and is very adaptable. The 2002 crank will take 250 - 300 bhp and you'll need forged pistons and an E30 318i head/manifold.
AVA in Glasgow did such a conversion on a 2002 Turbo, used the standard 5 speed 318i gearbox as well. I'd fit a 325i output flange along with the bigger donut though.

my mate turbo'ed his mk2 astr gte using an escort s1 rsturbo loom with an ahmed bajoo chip.christ that was a fast car.
