Tuning

[rwikky]

Hi everyone.. ive bought a E30 318is M42 this summer! but a couple of ma mates are sayin its lackin a lil performance! iv asked around about tuning the engine but a couple of garages have sed it cnt be done.. im sure theres summit i could doo.. isnt ther??

your very limited,
FI is the only viable option aside from engine swapping or getting a 325i or 335i already.

oi why does everyone say that! gunni you've seen sam's 200bhp+ NA engine and mine's not too bad either. There are other options, sure they're not necessarily as easy as with other engines, still viable though.

It´s a cost vs HP ratio.
plotted down 200hp from a M42 na style is not going to happen that easily while 200hp from a turbocharged m42 is easy and simple making way more low end and overall drivability. A stock M42 with turbo only can reach 250hp easily.


I also said your very limited, meaning sources aren´t that much for information.

Well, 1st thing to do is to buy a chip from M5 pilot anyways. That'll probably give you the best bang for buck that you'll ever get from the M42 for only a 100 quid and 5 mins work to put it in

Then, you can decide do you want more after that

Could get a JE flywheel too that'll make a nice difference to acceleration although they are pricey.

The sky is the limit if you have deep pockets. 500bhp would be possible if somebody went crazy with a turbo conversion.

But the engines are far from being limited to tuning. They are just as capable or maybe even better to tune than any other N/A engine imo.

Obviously engine swaps will always be the easiest way of increasing power substantially for a given cost..... but where's the challenge in that

alright, i'll let you off

The worst is that it can´t go that large in size.
Otherwise it´s one nice engine.

The car was bought wid a air filter induction kit.. (i was told tht was suppose to get +3/4bhp..) but im just tryin to restore it n make it have tht litlle extra torque when i throttle it! u guys wanna piccy of it??
