E36/46 Ecoboost Swap How-To:
Step 1: Prepare the chassis.
You will start by removing the blower motor cover. Once removed, some slight trimming will be needed for the HPFP to clear the firewall. ( You may need to install the engine a few times to get the cut right. ) This isn't a structural part of the chassis, so don't stress cutting too much.
Now that you have room for the engine, there's one more step: Removing the OEM radiator mounts. This applies to E36 & E46 models if you prefer a simple radiator hose setup. (If you keep the OE radiator, the hoses will cross over from side to side. ) We offer brackets to install a Mazda Miata radiator, as well as a hose kit to make an overall ease of install.
Step 2: Prepare the drivetrain.
There are a few key steps to get the engine ready to go in the car. First, you will need to remove the OEM oil pan and pull off the balance shaft. Once removed, install a balance shaft delete plug. This is required as the engine is too tall with the balance shaft on to fit into the car properly. Now that the BDP is installed, we can install an oil pan.
You have 2 options for the oil pan. The first option would be to purchase our billet rear sump pan that holds 6 quarts and comes with a baffle. The second option is an oil pan from a 03-11 Ford Ranger 2.3 Duratec. We have found it best to source this pan new from Rock Auto. This pan only holds 4 quarts and requires modification to the oil pick-up tube.
Now that you have your oil pan selected and on the car, let's get those JEM-Sport engine brackets on. (E36 / E46: make sure to select the correct engine, 2.0 or 2.3) These brackets utilize the OEM engine bushing! So make sure to save your OEM engine mounts if they're in good condition!
The last step is installing your ZF5/ZF6 transmission adapter. If you have an aftermarket clutch rated for the power of the EB, don't throw it out, as you can still use it with our kit!
It's that simple!
Your transmission remains in the OEM location, meaning nothing from the transmission back needs touched. No cutting up a shifter hole, no custom driveshaft and, No crazy one-off trasnmission mount!
