turboing and e36 m3 evo engine in a e30,

[midnight]

what kind of work needed? how much will stadard internals take, and links for parts and costs, any help much appreciated

[jaistanley]

Well, the major headache with fitting the 3.2 engine in the E30 chassis is the manifold. If you turbocharge the engine you are immediately negating that one....

Not sure if any aftermarket M50/S50 E36 turbo manifolds will fit both the engine, or in the E30 chassis. Theres space where the washer bottles currently are.

Lots of people will tell you you have to change the inlet plenum because of the 'soft' unions between the trumpets and the plenum. I dont agree, I recently saw a 999whp 'charged 3.2 on you-tube that was running the std plenum. Yea, they swelled up a bit but it was fine!!

You'll be looking for a large and high spec turbo, massive intercooler, new massive injectors and aftermarket ECU that can handle Dual VANOS. NOT a cheap project I'm afraid.

Good luck!

what about a supercharger ? Are there any companys in the uk that do one for the s50 engines ?

[jaistanley]

I'd personally much prefer a supercharger, volumetric, roots or centrifugal alike.. More linear power curve etc. It'd be the mut's NUTS! (and much more useable).

i think some one is getting ideas!

[Kos]

DA motorsport have some bold claims about their turbo charged s50/52 engines

and turbo manifolds are available off the shelf

3.2 evos break rods for fun and double vanos is troublesome oh and 6sp boxes die so i'd stick to a 3.0 s50 and 5 sp box

[JazzMan]

http://www.ca-automotive.co.uk/ do a lot of supercharging stuff, certainly worth giving Roy a bell.

[jaistanley]

The 3.2's dont break rods for fun, they stretch rod bolts don't they? Set of uprated rod bolts and the inclusion of forged pistons (for lowered comp ratio, but have the benefit of being lighter) fix that.

The VANOS can be a pain if not looked after properly... So look after it properly!

You can use the 5 speed gearbox on the 3.2 (I am as I didn;t get a 6 speed with the donor car).

To be fair though, if I was to do a forced induction S50, I'd go for the 3.0 litre too. Simplicity of the VANOS control strategy more than anything. You might even be able to get away with keeping the VANOS ECU and running a simpler ECU set up (though don't quote me).

[ste]

A waste of an S50 IMHO. Better off starting with an M50 or M52...

[jaistanley]

True... The S50 is a development in N/A tuning. You dont need the higher duration cams, fancy inlet plenum, throttle bodies, higher compression ratio etc etc for a forced induction engine so why waste the money on them?

In fact, an early non-vanos M50 with 2.8 crank and rods, plus forged lower comp pistons is ideal!

That said: I like the idea of ragging around in my S50 E30 (one day eh? ) then later on supercharging it for another project.

cheers guys its a mate of mine who is interested, im kida the middle man, by the way what is vamos is that the type of ecu it uses (ie. motronic)

[maxfield]

No variable valve timing.

[midnight]

hmm sound long tings really
is it really worth the hassle

[ShepsEvo3]

I have dyno'd an E36 M3 with a Rotrex Supercharger fitted, with standard internals and just remapped and it pused out over 365BHP with torque to match. Boost was approx 5/6 psi, but it has seen 10psi. The engine has also done over 160,000 miles and has not been apart - yet! It is a 3.0ltr. NOT 3.2.

HTH.

[midnight]

hmm sounds interesting

[Demlotcrew]

TO super charge a E46 M3 you are looking at 12k for a fitted kit.

[ShepsEvo3]

The E36 M3 I was talking about was "home" made, The Supercharger was by far the most expensive thing to buy - close to £1400. But a Saab 9000 intercooler was used (£50 scrappy) the next thing is getting jiggy with some pipes and metal work for a suitable bracket to bolt the charger on. I think the whole thing with a mapping session didn't come to any more than £2500 - ish!

thats a lot of cash. surely turboing would work out much cheaper?

Supercharging is proven on the S54. I've only ever seen one turbo charged S54 and that is in a E30 M3 shell.

[zimmerbimmer1]

I say go for the M52B28 and turbocharge that. Standard internals can handle up to 400bhp

[Kos]

to do the job right will cost well over 5 grand, and a turbo will need an intecooler and manifols, with a supercharger you can use water injection on a boost trigger switch so in theory cost will be lower

but you are talking about a 2 grand engine, not a 100 quid m20 which are readily available so job must be done right

a lot of the turbo/chrager set ups are based on US m3's which is a 3.0l m50 with cams and m50's are more plentifull so thats a better option

[maxfield]

They're based on an M52

Sorry to be pedantic
