m44/m42 spec rally engine

Trust me Rohan im dying to take it out! Im leaving the prop on until the car is more or less ready for the rollers.

Got the front end on now and fitted new wings as old ones were rusty as are all the wings on e36s!.

Got a few things to do this week. Sort a fuel leak from above the tank. Fit a rollover valve to the fuel tank as im getting rid of the charcoal filter and fit a oil temp guage.

[Darky]

Which oil temp guage m3?

[sh123]

Not sure.

I was thinking aftermarket and fita guage to the centre console. And after the rolling road im thinking of fitting a pressure guage and a pressure warning light. As this is a competition engine its always going to be on the limit.

Would m3 involve changing dash?

[Darky]

No it wouldn't, not on the e36. You already have a pressure warning light!

It just replaces the fuel economy guage, fairly common for e36! You'd probably be able to get the 8k tacho with oil temp guage!

[sh123]

I dont have a fuel economy guage. And I need it done within a week.

And ive read that standard warning lights come on to late. And damage will be done by the time its on. Maybe its not true on bmw's

[Darky]

You don't have the fuel economy guage below the tacho? True a week is pushing it badly.
What did your engine builder say your new redline is?
Standard warning lights come on late, where did you read that?

[wazzu70]

I think he means the pressure in which the oil needs to drop to trip the light is too low. Engine damage has already occurred by the time its illuminated.

[Darky]

You could easily replace the standard sensors for more sensitive ones.

[sh123]

It is definitely a possibility! Ill see what happens when it gets mapped. Ive got a temp guage on the way so that is now sorted. And after the mapping ill sort out what to do about pressure guage and cooler

[Darky]

The warning gauges would be just normally open or normally closed switches that change stat at a pre determined point, buying a different gauge sender would be all that's required!

E36 m3 gauge clusters aren't too expensive either. E30 ones are poisonous to buy.

[sh123]

10 or so hours and she'll be getting mapped!!!!

[Jaker]

10 or so hours and she'll be getting mapped!!!!

And???

[sh123]

Car is still with the mapper. Hwe ran into some problems so he had to change a chip in the ecu etc.

So hes calling me when it's done.

FWIW, I just looked at an E36 M42 lower manifold. It doesn't have the breather cups and uses standard-sized injectors with the small holes.  Looks like you have it running already, tho. Great news! 

[sh123]

thanks for the info benz-tech! yes its running

she made 170bhp and more than 160ft-lbs  of torque ( I say more as he didnt know what the figure was at the time but he knew it was more than a 2.0ltr m42 that made 160 on his rollers) so ill get accurate figures tomorrow!

abit dissapointed with power figure but everybody says torque is what you need in the rallying I do. So im excited!
