Hi guy's. I have a 1997 m3 evo e36 and would like to know how much work is envolved to turbo charge it. Anyone have any experience ?
Thanks

MadMac

I could imagine it would involve quite a lot of work. Just googled some sites and there are kits out there, but they ain't cheap.

yeah,done the same mate. Far to pricey. Thanks for having a look for me.

i wish i had done this to mine instead of building my R5 lol.

ive turboed several things like this before. Can you weld, solder, read electrical drawngs, do mechanicals, understand engine management and map cars? all these things will help, making a manifold is the trickiest bit, and wiring up an aftermarket ecu and mapping it can be testing, would be a good project though.

my mate neil had a e30 m3 and at the same time i had a 2.5 16v 190e cosworth that i always wanted to turbo but never did

supercharging is better

chaffe

lol, why?

Jay,

well responce is better from the off and a linear power so a lot less stress on engine ect more reliable and the sound is awesome

paddy145

lol, why?
Whats so amusing about that ?

Space issue's

i see, a 3 litre straight six is quite responsive anyway lol, adding a turbo just adds to the responsivness. im not into the whole "crying baby noise under the bonnet" love the whooshing hissing of turbos though, how do you go about sizing the supercgarger when doing your conversions?

chaffe

cant be that tight under there is it? most turbos are smaller than superchargers, they both have similar pipework to contend with

Give these guys a call, they know a thing or two about turbocharging BMW's

big_wig_074

space is a massive problem on the rhd e36,you can fit a supercharger on the inlet side of the engine far easier than messing about squeezing a turbo in around the steering column.

chaffe

put the turbo on the inlet side and run a pipe under the car to it from the ex man? ive got a 2ft pipe from one bank of my v6 to the turbo, no probs

big_wig_074

it can be done,but the oil filter and loads of other stuff is in the way there,its a really compact bay,centrifugal is so much easier

chaffe

When i turboed my 318 is E30 i put the turbo almosy on the rocker cover on the exhaust side, and flipped the manifold to feed it, anything is posible, just cant help thinkng that a 3 litre with super charger will be wank on fuel, but witha turbo it will at least be ok when your cruising around

Chaz888

would that be a ford 2.5 v6 cos Im thinking of a turbo for the coog seen it on a st24 and the turbo was right next to the TB.

chaffe

looks ace, i see he is using the same cheap ebay turbo i am

big_wig_074

6 pot is a lot bigger than 4 pot and the e30 has a bigger bay,it can be done,but theres no kits and its a lot more hassle thats all

brizie

It sure seems to be doing the business

chaffe

i see,its longer, not wider, i dont see it as hassle, but as a hobby TBH, i quite enjoy manufacturing all the components involved in a turbo conversion, thats what makes it different i suppose

chaffe

150 quid well spent IMO lol

brizie

Haha can't go wrong at that!!

Any more info on the e30 bud?

MO' BENT RIMS

go on to the e30zone.com thely tell u all about it

chaffe

Std compression, inverted and modified std tubular stainless manifold, t25 flange welded on, 28 turbo, custom down pipe, frontera tdi intercooler, custom boost pipes, fifth injector setup, oil return into the rocker cover! was ok, but prehaps not the best turbo conversion ive done.

Jim Galbally

step1) sell m3
step2) buy turbo car

et voila, the cheapest, easiest, and most reliable method

why when you can do the conversion like above Jim lol you know you want to

i had a bmw e30 325i and turbo'ed that it cost me 4k all in done a lot of the work myself. the biggiest cost is the manegment system,loom setting it up. job for the pro's i got s*it load of pics and full spec some where il try and dig it out for for it will give a ruff guide.
but it may cost loads to do but at the end you got some STUIPED POWER PURE TARMAC CHEWER

brizie

4k? fuck maybe i wont be slapping a turbo on my e30 then!!!

hynes67

yes but u did the build on a wim not knowing where to get cheaper parts etc. and i spent all my time on it i dint wait for the bits to come up i just went a payed top wack dosh for the bits i have heard it done a lot cheaper but like all thing the cheaper the parts the quicker it will break if all that makes sence

twoblacklines

JBS will make you a proper custom manifold. Expensive though.

Better off building your own kit, you will need to anyway as its RHD.

hynes67

and dont do anything under 2.0l i used a m52 325i out off a bmw e36

brizie

Yeah was thinking 4k is a tad steep if you were doing the majority of the work yourself, get some more info and pics up mate, would love a look

brizie

IF and its a big if i ever went down the fi route i would be using the m20b25 just to make life simpler, heard the internals can handle a good bit of boost.

hynes67

and on a m20b25 put a 5 serise bottom end on it and it comes a 2.7i my m8 has done that to his car and its fooking quick the tourqe is stupid
fancy turbo that lump

Dlatch!

i would supercharge it personally

plenty kits about too
