8,500rpm s50....

Rotary would have been awesome but s50 is still great choice. Cars looks super clean too.

Ha i figured it was around that cost!

is this a track car? or just a badass street car?

It's really just a badass street car.

I intend to take it to the local tracks to have some fun with it, but (at this stage at least) I don't have any intentions to cage the car, gut the interior and turn it into a full on track car. Never say never though.

Thanks mate. Yep lots of $. I haven't worked out a final cost yet but the Motec ECU and dash alone were $6,200.00.

Also forgot to mention that in order to get the most out of the engine the valves will be multi-angled.

I knew I had forgotten things.

Wanganstyle built a 40% lock up 3.25:1 medium case LSD for me. I bought this before I decided on the big build. I hope it holds the power!

KW V2 coil overs are waiting to be installed.
Brakes are 310mm all round - Wilwood 6 piston front and 4 piston rear from Ireland Engineering.

I have a Ford Fiesta brake booster out of the E30 that the engine came from. If the carbon air box fouls on the booster then I will get either a Wilwood or Tilton pedal box and switch to manual brakes. I may just do that anyway. I am undecided.

The steering shaft will be a hand fabricated piece by GT Auto Garage.

What are your plans for brake booster and steering rack shaft?

[Brisbane E30]

Haha - you're right about it being the bogan's choice Australasia wide. I'm very happy that I made the decision to keep the engine a BMW engine.

It should be pretty quick when it's done. I can't wait.

[Ray Smoodiver]

20B PP, the choice of bogans, Australasia wide!

But seriously, that thing is gonna fly! I'll be keeping tabs on your RHD headers for sure.

I've posted a little here and there about my car but thought that it was about time that I start a build thread to chronicle the current build of my car.

The car is a 1990 brilliant red E30 318is. When I bought the car the M42 was standard save for a K&N filter and new exhaust system. The car looked and sounded nice, but having previously owned both an E46 M3 and an E60 M5, was very under powered. I considered all manner of builds- including an NA M42 build with ITBs, turbocharging the M42, a 20B PP rotary conversion. I eventually settled on swapping in an S50B32 when a mate of mine decided to part out his E30 in which the engine/box etc was installed.

My good friends at GT Auto Garage were charged with undertaking the swap for me. However it has turned out to be far more than a simple pull the old engine out and put the new engine in job. I have decided to completely rebuild the S50, delete the VANOS and install a stand alone ECU. The list of what I have ordered and is currently in transit to GT Auto Garage is:-

Pure Performance Motorsport (PPM) 12.5:1 forged pistons
PPM H-beam connecting rods
Cat Cams (CC) 1303315 camshafts
CC race followers
CC lash caps
CC double valve springs
CC upper retainer
CC lower retainer
1mm oversize racing valves
ACL Race connecting rod bearings
VAC high volume oil pump
VAC groove hardened valve locks
VAC high performance main bearings
VAC high performance valve guides
ARP head studs
ARP main studs
VAC crank damper
VAC VANOS elimination kit
VAC under drive pulley kit
UUC Evo 3 SSK with DSSR
MOTEC M84 ECU
MOTEC C125 colour dash
Göke carbon fibre air box
Custom headers and exhaust

I think that is the whole list :)

Additionally the dash, centre console, door cards and rear parcel shelf are being re-covered in black alcantra with the "M" colour tri-stitching.

I will be looking to turn the engine to 8,500 rpm and the goal is about 400hp (crank).

Here are some pictures. The engine is currently test fitted in the engine bay so that the headers can be fabricated. It is a real PITA that the car is RHD that's for sure.
