E30 Touring M60 swap

[bongo78]

First start :)

Car is nearly ready :), played with the wires last night. Exhaust is really loud being just 2 midsections in the moment. Does anyone know what OEM BMW exhaust can be used in that little space in the back? The least I am searching for is a 2x55mm.

Car is 99% done, drove it today with the exhaust - the E30 left me speechless and smiling without reason since :) Brakes are amazing, engine pulls like a train. The S2.65 that I bough wont be needed S3.25 is more then enough with a 6 speed, could cruise in town only in 5&&6 no problem :). Many people showed interest on intersections asking about the car, only straight answer they got was my wide smile :)

First start

And today nearly done

nice! im glad you like it

Not sure if it's an installation problem, but when left for long on rev limiter engine goes in limb mode selfgasing between 1-2k rpm and limiter moved to around 5k. Once engine is restarted everything comes back to normal?

[Jonsku]

Speed signal missing from ECU.

[bongo78]

Is it usual when left on limiter while on neutral? I used to have that problem with the M52B28, when the diff speed connector was rusted. I will have a look again hope that will sort it out. Need a pointer on how to squeeze the original air-box in there? The original E38 one is way bigger, not just the bottom part, but the top as well? Thanks.

Now came time to think about the correct tacho, for both schematics a 4cyl plug is needed :)





both will work to devide the revs /2 , I have tested the second one works well. Now I am updating the schematics for a proper fabrication :)

[bongo78]

Today I got 9,5mpg which is about 25l/100km city driving. That made me feel stupid at the pump ;( . Any one any ideas??? There are no errors on the ECU.

[Jonsku]

Hold your gas-foot higher ;)


I'm doing 12..13 l /100km on highway, in city 15..17 depending on how much I floor it.

25l/100 is way too much, read your error codes etc.. Lambdas or temp. sensors are the first ones to check.

[bongo78]

Thanks,
No bad codes, temp sensors are in range. I believe that the battery might be the one to blame. When that consumption was recorded I was forced to recharge it several times (taken off the car), and always once warm to floor it. Now I have a brand new battery installed, I was told that first 20-30km the ECU is self-teaching itself therefore gentle driving is advised :). My first trip about 300~km gave a 12.3l/100km mixed economy.

[bongo78]

Few things to fix the economy :)

74ah Battery


Bosh universal O2 sensors, sprak plugs, new air filter


Little work is required but compared to the triple price of the OEM


The result of changing the "working" O2 sensors and the new spark plugs is amazing :). Engine revs like mad, no hesitation whatsoever in the throttle department :D .
