I've a e36 318i cab and I'm wanting to turbo it,I've been told I can bolt the kit on and I won't need to do anything else apart from turn the ignition on then off then on and it should of set it's self up? I've no clue about electrics but ok with fitting the turbo,any help would be great
Cheers,Cookie
Hmm
Not sure who has told you this Cookie but they are talking utter sh*te :hihi
Its not a simple job to turbo a car that was naturally aspirates (non turbo) from the factory.
Depending on the turbo you may need to lower the compression ratio of the engine with a head gasket, and you will also need to consider the following
Intercooler and pipework
Oil supply and return from the turbo
Inlet manifold
ECU * this is the biggie, you will need to get a custom chip or remap for your ECU that accounts for the turbocharger. THis is a specialist job
Otherwise your car may/may not run, if it does run it will run badly. and it will very likelly grenade the engine in a very short time
depending on what boost you intend on running, you may require, forged pistons, conrods, uprated valves, valve springs, turbo profiled cams, you could also port+polish the head,
a lot of work with turbocharging, but, well worth it for immense power
mate
if you want bolt on power a supercharger is the way to go, you will how ever need to emap the ecu but this program should be contained within the kit:thumbsup
Thanks all
Mine is a m43
Think I'll look into supercharging as I was told if I ran at low boost I wouldn't need to do any internal work either,knew it was to good to be true
Makes no difference low boost turbo or s/c , all the engine sees is positive pressure.
Do some more research, you can do a fair bit on stock internals and the right fuel pressure.
Not sure if the m43 engine has knock sensors like the m44, ignition needs to retard as you come on boost, the m44 does this with it's ecu and knock sensors. Not sure about the m43
it is perfectly possible to run upto around 4-6psi safely on stock internals
I went the s/c route because i like the more linear power delivery, power and torque is instant off the throttle, no turbo to spin up. And its a bit different !
My car makes 4.6psi at 2000rpm and 9.6 at 6500rpm
s/c does sap power from the engine, so for ultimate power turbo is a better route.
look on some of the US forums, they are pumping over 1bar with stock internals
i was looking at a v40 20t or s40 20t but the turbo is in at 2.5k and have a shotish life span so when your at 60 mph at 2.5k your turbos in and being used even when you dont need or want it. i would use a s/c :thumbsup
or a bigger engine imo :thumbsup
the turbo on the 2.0t's have a span of 100k and most of the cars are over that so i thought if you do 60 mph the turbo would be in, and with that mileage at the end of its life
So what sort of money is ok to pay for getting it mapped once I've put my turbo kit on?
I know what's involved in putting the kit on,manifold,oil feed intercooler pipe etc so what would be after that? And also is it easier cheaper to do this on a say 320 6cylinder?
Thanks for all the info,really helping
good thing to do when you run a turbo'd motor.
when you get home or turn the engine off is to let it idle for at least a minimum 30 secs. this gives the oil a chance to cool down on return from the turbo, yhus prolonging the life.... i should know, i ran one for over 120k in a subaruand its still the original
