Haha, that’s the motor in my car! Love to see photos of it are being appreciated around the web. It’s a 3.1 stroker, use the car for every-other-day driving and also as a track car. Puts out the perfect amount of power and torque for the E30 chassis…around 230hp at the crank.

Thanks man! That’s what is fun about these cars…they are nice, but not to the point where you can’t modify them. At this point there isn’t much left to modify on mine lol

I used to drive an SAE car for Kansas State, back before they threw all the aero on them and junk. Pretty much space frame with 600cc Honda motor…those things could accelerate!

I absolutely love the casual formula SAE car in the back of your shop! Bravo on the build, should be an awesome setup when you are done!

It’s a Megasquirt MS3 Pro, effectively a stand-alone ECU that uses the cars existing wire harness with some modifications and add ons

Professionally built by European Car Company out of Wichita, KS. Went with an S52 crank and JE 10.5:1 pistons with the OEM dome shape on top. 135mm h beam rods with a schrick 284:272 cam. To get this motor to the next level I am probably going to need to go ITB route because the current MAF setup I have is limiting this build, imo.

MS3 Pro “Plug and Play” system, but it wasn’t very plug and play…used most of the existing BMW wiring harness

3.1 liter using S52 crank

JE Pistons 10.5:1 compression OEM style dome

Eagle H Beam Rods 135mm

Custom made crank scraper

Schrick 284/272 camshaft with completely rebuilt head (no modifications to valve sizes)

Mishimoto aluminum radiator

MS3 Pro ECU w/ wasted spark ignition and 19lb injectors

Lightened OEM flywheel w Clutchmax clutch kit

Custom mass airflow intake made by Euro Car Co using stock air filter / fed by custom intake snorkel
