Whats the story behind your E30? Bought it two years ago as a empty shell with a load of parts on the side. Everything is rebuilt, the paint is brand new, the only thing I had from before I bought the car was the engine. The engine is a fully built S50B30 with a Precision PT6765 turbo. It delivers 750whp@1,5 bar of boost and 910nm at the wheels. The goal was to create a car with plenty of power which is able to  be used everywhere.

What got you into E30‘s? My first car was a 1990 BMW 318is 16v which I also put a turbo on. It probably left somewhere around 600hp. 

How many E30‘s have you owned: 5

What‘s your favorite E30? The M3 of course J

What are you working on now? Reinstalling Vanos to gain low end power. Replacing the old turbo with a PT7675 billet. 1000whp is the goal!

Any plans for the future? Recently bought a BMW 335 double clutch DCT (DKG) gearbox. Me and my programmer friend will try to develop a management system for these gearboxes to retrofit them into any vehicle. If we succeed my M3 will be the first in the world with a aftermarket management system for this kind of gearbox!

Interior: Two Sparco bucket seats, a half rollcage and a couple of Autometer gauges.

Exterior: Sport Evolution rear wing with carbon flap.

Wheels and tires: BBS LM 9,5×18 rear with Toyo R888 235/40 -18. 8,5×18 with 225/40 -18 Bridgestone street tires.

Suspension mods: AVO coilovers all around. Millway adjustable camber/caster plates front. Adjustable wheel alignment rear.

Brakes: Porsche 4-pot calipers front with Audi S4 320x32mm rotors. M3 e30 standard rear. ATE Super blue brakefluid.

Drivetrain: M5 E34 rear end. BMW 530d gearbox. Clutch Sachs 707.

Engine: S50B30

Exhaust: 3,5” stainless Feritta by PPF




Really happy to be featuring this BMW e30 m50 turbo that my friend Aron Jarl owns. Great project and well planed with detailed finish.

Wich forums do you use? and little bit of everything.

Whats the story behind your E30? I´ve had a few e30´s since i was 18 years old, I bought this from Germany march 2007. Then i had a e30 m3 that i was goin to make up but the shell was completely useless because of many collisions and very poorly repaired. So i decided to buy a good coupe pre-facelift e30 with Mtech-I kit. Which is the nicest besides M3, So i found this a very good price, 3 owners and no rust. My plan was to move allt the parts from the m3 to this one, which i did. Since 2005 was i had a big dream to make a m50 turbo e30. But i had to put up with the s14 (m3 engine) for 3 years while i was in school. I started slowly collecting parts for the turbo project.

What got you into E30‘s?  I´ve always loved them, i´ts just something about them. I´ve raced/drifted on e30 for seven years and i have incredibly high sense of how they behave on the street. When i got a driver´s license was only two cars that i wanted, e30 325i or Peugeot 205 Gti. (now i have both)

How many E30‘s have you owned: two trouring – one m3 and six coupe so its nine in total.

What‘s your favorite E30? My favorite is e30 m3

What are you working on now? Waiting for the summer to burn tyres, maybe installing a new suspension – KW variant 2

Any plans for the future? Re paint the car and make the BBS RS like new. Make the car flawless.

Interior: Im a big interior fan, i have e30 m3 complete interior, Recaro SRD from ITR and Sparco race seat to fit in when im competing in drift.

Exterior: Full M-tech I

Wheels and tires:

 BBS RS 17‘‘ 8.5×9.5‘‘ BF Goodrich G-force 215-40-17 – Dunlop SP 9000 245-35-17

Suspension mods: I have to work on that, plan is KW Variant 2. But i have the 5 lug system from e30 m3

Brakes: Front- disk from MB w124 500e 302x28mm and brake caliber from BMW e32 740

M20b20 pisron rods thay are 4.5mm shorter than m50b25
M50b25 ”oem” pistons

Exhaust: The turbo manifold is made by me welded and fitted – split pulse T4 flange with TiAL 44mm wastegate 3‘‘ straight flow system made by me.

Anything else you want to elaborate on?

Turbo parts.
*KKK k27.2 turbocharger
*TiAL 50mm blow off
*TiAL 44mm wastegate
*Turbo Manifold is made of black steel, costum made by me. (Split pulse)
exhaust system is 3” straight back, a little bit noisy, plan is to chance that in winter.
*CXracing intercooler.
*Injector are from MMC Evo 8 560cc with 3bar but m50 runs 3.5 bar fuel pressure so they are a little bit bigger they are perfect for this setup.
65% duty cycle at 13psi boost.
*Fuel pump from Mercedes w211 e55 AMG (Bosch huge one)
*Costom made motor arms by me with Poly urithan mounts
*M50 UUC stage 2 clutch kit from (two mass version)
*I used M20 flywheel and modified the clutch on that.(lighter and better than two mass weak and heavy flywheel.
*Getrag 260 from m20b25 great and strong gearboxes but i already broke one this summer the 3rd gear.
*custom made drive shaft.
*Rear Diff is from e30 m3 euro Limited slip 3.25:1 (Z3M diff cover) (so i have very long gears and more lode in the drive train for the turbo to spool faster up) its necessary for light car like this.
*Vems standalone system.



the engine is performing @ 8psi about 320-340hp
12psi about 400hp
19psi about 500hp it spins always wheels in 3rd gear on straight line.

limit on these m50 with orginal piston are around 540hp

Many turbo guys here in iceland say this is að PERFECT setup.

i spent alot of time to think about m50 turbo,
size of turbocharger and how it fits together.

Whats the story behind your E30?

After going to the Nurburgring in 2006 I got infected with the Ring virus.  It was pretty obvious that my E39 M5 was too heavy to be an useful track car and I didn´t want to trash it.  So I wanted to get a smaller and lighter car to track.  Always liked the E30 M3 and decided to get one and modify it for track use, mainly at the Ring.  Car was taken to Tauber Motorsport in Germany in 2007  who did the engine swap and all the mods .  They used to race E30 M3′s in the DTM series and are very competent and knowledgeable.


What got you into E30‘s?

Always liked them from since they were racing in the DTM in the 80′s.  Handle well and look awesome.


How many E30‘s have you owned:

Just this one.


What‘s your favorite E30?

Don´t have a single one to pick out, lots of nice ones, but I really like some of the S85 swaps being done.


What are you working on now?

Just installed a new fuel tank, need to fix some rust issues, reinforcements around strut towers, upgrades to safety equipment.


Any plans for the future?

Stronger rods, standalone, improve exhaust and some more stuff.  This car will probably never be “finished”.

Anything else you want to elaborate on?

The car has been an absolute joy to drive, handles well and is fast.  Has surprised alot of expensive machinery at the Ring and Spa.  Porsche GT3RS and BMW M3 CSL owners have been severely annoyed.  Best lap time so far at the Nurburgring is 7:55 BTG – link to video:
