#1: E30 M20 L-Jetrionik Conver To Motoronik? Author: al3dx, Location: Kota Kinabalu, Sabah

Hey Malatians & Sifu-Sifu...
I have one crazy project...
That's is to defeat the M50 Singal Vanos Engine with an M20...
But anyways...

I was thinking to convert my M20 Engine To 6 Throttle...
Now using a E30 320i L-Jetronik..
Let's Say If I change my M20 to 6 Throttle...
Do i have to change my Engine AFM to MAF Sensor?
Which Technically Means Do I need to convert to M20 Motoronik?

But what's the ways to convert the M20 L-Jet to a Motoronik Engine?
Change the cylinder Head?
Change the Intake Manifold To the Motoronik Type?
Change ECU?

Please help me on my quest...
Thanks To All...

Alex, E30 SA

i think jetronic system itself is more potential than the motronic system.u can tweak and play around with more stuff.its like how proton's engine system last time werby d older batch of protons run on mitsubishi ecu and the newer batch runs on siemens.u can tweak more on the 1s runnin on mitsu ecus than the dull dead set siemens ecu.otherwise,i culd be wrong tho.

just my 2 scents.

my own ride runs on the 1st batch of the motronic system which is quite headache enuff.

Sorry to hijack, just a quick question. would there any improvement on horsepower if i was to change the throttle body from a present M20B20 to M20B25?

what lah you guys...
Rojak a M50 in side an E30 is so common..
Have you guys ever thought of using you're original engine..
Improving it...
So that it can beat the M50 Engine..

I planned to Rojak M20, so that it's more has better responds..
not only that...
I planned to beat the M50 Engine...
I have a few planned to do up my engine...
One of it... is... (Cannot Tell)

your trailing arm cannot tell. You will reach about cannot tell.

Manifold have to use cannot tell with cam shaft cannot tell.

Taddaaa... you got one mean machine!

Dewd, next time don't start a thread if you're not sharing anything. Asked so many questions end up want to keep the answers to ur self.

This is an Online Community NOT a CallCentre or Helpline where u can get answer by NOT contributing anything, try to learn how to mix around.

Cheers!

yep , m52 turbo = gHost in a shell .. =)

depends what u want , u want power vs handling or power with handling ,
so many cara to do it , too much power , handling sure kacau .
let's not forget it an e30 chassis . not some new e46 chassis .
gotta think about the poor old 'bird' also .

what ? want to match a M50 power... easy, dun need to sweat so much or burst your piggy bank...

1. put in a 2.7 block bottom end, make sure it's the 9.8 cr pistons.. need to buy new. blue print the engine.

2. port and polish the head, only inlet, enlarge the intake ports, gas flow it

3. do a 3 angle valve cut on the inlet valves, if possible do the decking for increase air flow

4. go with a 282/272 cam, this the lease aggrasive cam, too much, your engine will be a washing machine.

5. use the L-jetronic system, easy power gains on the distributer timing.dun need to use the chip, cos L-jet no chip, motoronic is much useless... less then 5hp with the chip

6. if can get a extractor -long length type, then better on the high rpm.

7. go with the e28 flywheel and clutch+pressure plate- better torque and clutch wont slip when doing drag- otherwise you will have a burned clutch.

8. go with a 260 getrag or a dogleg gearbox... dun use shot shift gearlever, it will ruin the box;

9. finally, final drive of 3.91 will be good.. very fast.. dun worry about the top end.. if the engine is balanced nicely, 7000rpm can stay..

10. others to play around, honed intake, enlarged trottle body, MSD ignition coil, e28 AFM, bigger capacity injectors..

All this, the engine will have 200++ horses...

cheers..

I'm sorry...
Just wanted to spies this tread up a bit man...
Anyways, Was Planning to Convert My E30 M20b20 to a M20b27 high compression...
Which brings me...
Converting the Head to a M20b25 Motornic will be the best way...
or keep the L-Jet system...

But this conversion is hard to find parts that's about it...

Whoa Thanks for the info...
was actually doing the same thing too...
I did have problem just about doing the AFM and the motornic system...
Thanks man...

Ok here is my project for my engine:
Originally: M20B20

Modifying:
- Bore to 2.7L
- Use 2.5L Forge Steel Stroker
- 2.7 Forge Crank Shaft
- High Rev Cham-Shaft
- Convert the head to 6 Throttle...
(Most of it is base on the Hartge H35)
- Open Port Intake System

Gear Box:
Well i have not figure out the gear-box yet... just putting that aside 1st...
but now i got a getrag gearbox... dont know what model...
but for now just need to find a 4.1 LSD,

Plus i also have to change my rims to 16"...

I want both Horsepower & Handling in it...
So yeah... that's all about it...
nothing special...

Sorry bro highwaystar & aRRrgghh....
Did not meant to agonize you guys...
but i'm still collecting the parts 1st...
Just got my 2.5 light weight Stroker... Smile

So yeah... In time...

Well, this is sharing, anyway... good luck finding all those parts LOL!.. whatever you do, safety comes first. Brake System need to update, Chassis must be strengthen. For me, i'm not ready for these set ups.

Might have more patience, keep some money to upgrade straight swap S52

OR S14

mmmm.....

GOOD LUCK ON YOU CONVERSION ALEX!
