Swapped E30 - need help :)

[Jorjika]

Hello...
New here...
So, as you guess, I made swap in E30 with M50B25...
it's good ofter M20B25, but I need more power..
I want it to be faster then now....
next week I'm going to put individual collectors...
i don't want supercharger or turbo...
So, what I can do?

[BMWman18]

turbo

[Jorjika]

but I don't want turbo... + in Georgia it's hard to find normal turbo kit and personal, who will install it...
I prefer to have atmosferic engine...

[Jorjika]

As I explained, I don't want to install turbo or charger....
how do you think, without turbo and supercharger, intercooler has any positive effect?
I mean cold air...

[gnastydent]

nitrous is the way when you wanna go fast it on a push of the buttom away

[Jorjika]

I preffer atmospheric engine
but, I think that soon I'll make new swap...
S52B32

i have a Q for you
how hard was it so do that swap and was the wiring a bitch to figure out, and besides the engine what do you need to put a m50/52 in an e30

[Jorjika]

It was not hard
I made it with my friend....
When I begin, after 48 hours my car was on a road
about wiring, we connected very easily, but at the moments of changing gears, cars had some stopping moment....
after two weeks, i figured out that it was "speed sensor".... it's only one cable to connect and it is serious difference for acseleration.
In wiring of europen M50B25's, from engine is wire Black with white, and for car it depends of model and year of your E30....

m3 cams, v8 air mass sensor, both with appropriate chip (look into bimmerworld, contact them they have archives), decent exhaust system. a friend of mine did this to his relatively tired m50b25 with shorty headers, m3 cams, straight pipe exhaust with 2 glass packs and appropriate software and he's putting close to 200 to the ground. and he doesn't have the v8 air mass.

oh crap, you're in europe. only if you can get a set of u.s. spec m3 cams will it work. and a "euro" m3 air mass then.

as I said, It is M50B25, but I made it as 2.8, lower part of engine is M52B28,cutted 1mm on it...
I installed individual collectors and air throttle of 4.4,exhaust is only two pipe and in the end is muffler od E46 330...
now it's prettty good, on drag race on 402m I won American M3, stock one....
Now I want to get software, without oxygen (lambda) sensor and air sensor....

[fourdoorfanatic]

you could still use the U.S. m3 cams, they are a bit bigger than the 2.5 or 2.8 cams. i didn't see you had the v8 air mass, so scratch that. software is the way to go, or standalone if your wallet is deep enough.

theese are old pics, I installed air throttle 2 month ago....
can you tell me where to find software for BOSCH ****413?
I want it to work without lambda and air sensor

[fourdoorfanatic]

uh, check bimmerworld.com. with all the other stuff (air mass etc etc)you may be pretty well screwed into a custom tune to get the best out of your components. "standard" chips like bav auto or conforti won't be a whole lot of help, not mapped for your components. i hope that makes sense, i know what i mean but have trouble wording it sometimes.

[Jorjika]

Thank you very much
