My E36 turbo build

[bearsbmw]

ok so it's turbo time for my chiped 94 m42...

1.  how much psi can I go while using chiped ecu maping and fuel injectors befor it becomes unsafe with the m42

2. can the e36 handle a top mount turbo?

I don't see much turbo action with the e36 M42 so It would be realy intresting to get some solid imput here ... thanks!

so nobody know's what PSI I can run on a chiped ecu without changeing up the injectors

It depends on how much fuel pressure you're willing to run.  

These are closed systems... a change in one area (adding a lot more air) requires changes in others.  I don't believe there is any such thing as a reliable, budget build that comes close to getting the most out of whatever you install.  Without the proper fuel and management you either leave power on the table by running rich or you blow it up.

I know what I'm talking about here.  A previous turbo project was a turbo Miata with slightly bigger injectors and a RRFPR.  Once I got to 100psi on the fuel pressure and starting thinking about that, I invested in bigger injectors and a real ECU (in that case, a Link).

I would make sure I knew how to do it right unless you can afford to be without a ride while you rebuild.

yes sir!...Are you on maxbimmer.com ottawa section? Ottawa BMW Enthusiasts(Facebook)?  you would be the second M42 turbo in ottawa... buddy is runing a e36 m42 all custom 13psi but is having major problems with cracking manifolds and shops that keep fucking him over... anyway swing your mouse over to http://www.maxbimmer.com/forums/forumdisplay.php?f=87 & http://www.facebook.com/group.php?gid=23104823544

Also every friday night we have meet's at Merivale and Meadowlands at 10pm... should bring that bad boy out... alex who has 2 e36 m3 superchared setups would prob be intrested to see your setup ...cheers

awesome setup! thanks for the ride again freakin fast m42

[bearsbmw]

for runing 8psi MAX  will it be nesseasary to use a wide band O2sensor ?

[George77]

Depends,You could use it when you do the tuning or you can permanently install it in the car and see if something goes wrong,so like that you can prevent a engine blow.

what spark plug's should I run while under boost?

what brand of 310cc Injectors(Low or High impodence?) can I use that will work with my fuel rail ?

What are my vacum issues that I will have to deal with?  (*my fuel injectors are air/vacum supplyed)

will emange work with my newer m42 bosch ecu/dme?

thanks!
