"I think it´s best I just toss this out here for all to see.
So your wondering about some more power for your 6cyl non M3 E36 and a turbo sounds nice, but also sounds impossible.
Here is a break up of how it can be done cheaply yet effectively.
Bear in mind this does require some welding and general fabrication.
First I´m always assuming the following for each scenario
"3 exhaust well open.
largest intercooler fitable
walbro fuel pump
Turbo manifolds are near impossible to find for the LHD E36. But If you buy a RHD ebay one and adjust the flange to angle the turbo a bit better away from the head then it´s as good as any other ebay thing. I´d recommend bracing the turbo when using one of these. Or making one yourself
so that out of the way rest is just the same as normal E36 turboing. The main problem being fuelling and ignition.
First vanos and non vanos ecu´s :
It would be possible to do the following scenarios
Rising rate fuel pressure regulator + STOCK MAF + Chip tuning (live mapping) + stock injectors. This should be able to yield in the order of 250hp or so.
fuel pressure adjusted to 5bar + STOCK MAF + Chip tuning (live mapping) + m3 injectors or something like 22lbs/min. This should then yield something like 300hp. The maf will be nearing maxed out.
Rising rate fuel pressure regulator + STOCK MAF + Chip tuning (live mapping) + m3 injectors or something like 20lbs/min or bigger. This should then yield 320-330hp or so, MAF will be maxed out but the rising rate will handle more fuel due to higher fuel pressure.
Larger MAF : i.e remove the element and fit into a "3.5 in pipe (same as S50 sized MAF) . MAF now flows a bit more. Here I´d recommend something no less then 42lb injectors and you should be able to see 400hp. This requires a bit of chip tuning to iron out well.
Standalone option :
Any power goal available as well as antilag, flatshifting, boost control and the list goes on and on. I personally would of course go this route as like to have alot of options open.
Now that we have covered that what has to be done to the engine itself?
Below 300hp I´d say nothing, but depends a bit on the torque produced.
350hp-ish, for a drift car lower compression due to higher torque will be required. I´m not sure that ARP studs are required here but I´d recommend them.
Anything below 500hp : MLS decompression plate and ARP bolts .
Now since the engine can handle what ever power you want what about the clutch?
For anything below 300hp I´d venture to say that the stock clutch will handle it, but for drifting I´d go 6puck straight out and never need another clutch for any power upgrade below 650whp.
Cooling system : fit an electric fan, it´s a given.
Wastegate : 38mm for anything below 450hp. 44mm above that, 60mm above 750hp+
Turbos :
To stay cheap here are some examples that are cheap
HX30 for sub 300hp levels I recon will be good.
HX35 for sub 450hp levels.
HX40 for sub 600hp levels.
If you shop around and know people with some turbos lying around and have fabrication skills this can be very easy actually."
