Cool The World’s 1st & Only S55 Swapped E30 - Cooled by CSF



Destined for SEMA, completed by 6 students who had never built a car before.

With multiple publications under its belt, you’ve maybe seen it by now – but this build is one for the books.



In less than one year, at a small home garage, six students (@honestassembly on IG) took on the seemingly impossible task of swapping the current generation S55 M3 motor into an E30 M3. Purists and collectors alike scoff at anyone that removes the S14 engine, but the performance is so worth it.

From the factory, the E30 M3 came with a 200 horsepower four-cylinder – an impressive performance feat at the time. With motor swaps, most builders use the drivetrain and some engine wiring, and that’s about it. This group of college kids, however, wanted to take this build to the next level. Instead of getting separate gauges and being able only to monitor a few vitals, they decided to take the entire working F80 cluster and adapt it to the E30 dash. Keep in mind not only are they the first to do this motor swap, but also were tackling the cluster and chassis wiring as well.



Taking the motor out of a much larger F80 chassis and putting it into the E30 chassis was not for the faint of heart. Although the engine did look at home inside the bay, it was an extremely tight fit. With such space constraints, the cooling system had to be the best that it could be.

The CSF Race High-Performance Charge Cooler is a familiar sight with many S55 builds and is the ultimate weapon against heat.

Let’s face it, many modern motors generate a lot of heat and are aluminum blocks. Thankfully there are many fail safes to prevent the block from being warped, but still there is an increased risk when that same motor has 2 turbos attached to it. On top of that the space its mounted in is smaller than before, this further increases potential engine bay heat.

The CSF Top Mount Dual-Pass Charge-Air Cooler (CSF #8082) is by far the best unit on the market to keep temperatures down. Not only is this unit drop in OEM fitment with no modification required, but the core it uses is also 60% larger than the stock unit. On top of that, being a dual pass cross flow unit, instead of the stock single pass vertical flow, it keeps the coolant in longer to make sure that intake air temps are as low as possible.



There is another piece to the puzzle of cooling the air though, and that is the heat exchanger. Since CSF was already signed on to the build, the group decided on also using the CSF Front Mount Heat Exchanger (CSF #8075) rather than the OEM unit that was in the donor car. Being a highly efficient 2-row core equipped with CSF’s exclusive B-Tube technology, the upgraded CSF unit can maintain the coolant temperatures much lower compared to the stock OEM single row unit.



Restoring a car is one thing, sourcing new parts and retrofitting is another. The stock E30 dash is flawless, the displays all work and on top of that a factory Nakamichi tape deck was sourced to finish off the complete package. With a classic combo of Alpine White exterior paint and Red Nappa leather OEM seats, this car still has the soul of the E30 from almost 30 years ago.



This OEM+ build has taken one crashed f80, a normal e30, and a lifeless e30 m3 and used the best parts of all three. The fresh paint, the immaculate interior, and the S55 motor make the car even better than it was before. Other than the livery and engine swap, this car still looks like a stock e30 m3. In fact, it caught the attention of CSF so much that it ended up becoming a booth car, displayed at SEMA 2018 and reaching the top 12 in SEMA Battle of the Builders.

JP Performance out in Germany are doing an S55 E30 M3 too; DCT, CCB, M4 front and custom rear pushrod suspension, M4 diff and electronics from what I've seen.

We know of their build - they've actually reached out to us for consultation as well as requested to use to use our S55 cooling kit on their vehicle.

It's supposed to debut at Essen Motorshow in November.

Good luck to them - all I can say, there is a big difference in building a car with this level of sophistication and calibration of the S55 management system, and actually getting it to drive well.

Yeah, and I am kinda scratching my head as to why they just did not widen the already-bastardised shell to accommodate the wider track of the stock F82 axles instead of shortening F82 suspension parts and developing a push-rod system for the rear which totally alters the geometry and driving behaviour. Now they have to run skinny tires, too. Threw the "we're making this to behave as close to an M4 as possible" out of the window with that.
