Aussie 318is - now S54B32 swap

A few more pics of the finished product.

That sucks about the motor. A s54 b32 motor should be fun to drive in a e30.

Harper fab front sump arrived - next step is mock it up on the motor:



Rod bearings/bolts have been replaced with ACL bearings and ARP bolts. Stock bearings looked ok:



And hopefully the last time for a while the e30 will be on a tow truck. On its way to GreshM Performance to have the S54 fitted:

Some good progress over at GreshM performance:

- Harper Fab sump was fitted to the S54 (photo below showing it sits higher than the steering rack bolts)
- RHD lightweight flywheel fitted to an OEM style 550i clutch for good street behaviour with the GS6-37BZ 6 speed gearbox
- Motor fitted to the E30 using Revshift black (street grade) poly mounts
- Karbonius airbox fitted to the motor
- PWR radiator was also put in place
- New OEM washer bottle put in place - going for an OEM+ look

Bit more progress on the swap.

• Radiator plumbed to motor
• Oil cooler plumbed to motor
• Fuel surge tank mounted in boot
• Brake booster moved over 25mm on firewall to clear the intake
• Brake lines matched to Bosch iBooster

Next steps:

• Finish plumbing coolant res to rad
• ⁠Wire in S54 ecu to e30 body loom
• ⁠Build exhaust
• ⁠Fit shifter and driveshaft
• ⁠Tidy up boot carpet, engine bay plastics, etc.

The swap is done and the car is home!

Everything was completed in terms of:

• Plumbing coolant lines
• Replacing fuel hoses, finishing surge tank, cutting carpet to suit, low pressure pump in-tank
• Custom power steering hoses
• Exhaust is a 3" mild steel single, 100 cell cat, resonator, tri-flow muffler - sounds great and no rasp that I can tell yet
• Clutch is a GreshM kit using RHD flywheel - revs are very snappy but the clutch is light enough that I haven't come close to stalling yet
• Motor mounts are 80A Revshift M5x swap mounts
• Condor LCA lollipops to allow room for exhaust
• CSL tune modified to suit

The engine bay looks great, exactly what I wanted with an OEM+ feel.

First drive was in less than ideal conditions: peak hour traffic and it had just rained so the roads were greasy, but it was pretty mental none the less. The car is a real animal, sounds incredible and feels great. I was only able to give it a short hit of WOT on the highway, but plenty of smiles were had.

Looking forward to putting some K's on it over the next few weeks, then will take it back to GreshM Performance to have any teething issues sorted.

Looks great.
How much power?
Are going to up grade brakes?

Happy to post updates here and provide detail. A much better system vs the occasional FB/IG post.

I'm not sure on power, would like to get it on a dyno. But these are the things that would affect power I think:

• Karbonius airbox
• 3" single exhaust with 100 cell cat
• Turner motorsport pulley kit with aircon delete
• CSL based tune

The shop quoted 375hp at one point, which lines up with some of the numbers I've seen online.

Brakes are currently:

• Stock size
• Brembo ceramic pads
• DBA 4000 rotors
• Audi Q3 MC (need to double check this)
• Tesla Model S Bosch iBooster
• Stainless lines

They work well at road legal speeds and feel like a brand new car does, but will need upgrading for anything more, also to make the swap legal where I live.

Looking at a 300mm front disc kit of some kind that will fit under 16" wheels. Maybe a 5 lug conversion and use E36/E46 parts.

350 WHP Dynojet with 3.5 exhaust and bigger headers. Carbon airbox +10~

My guess 325 - 335
