Non Turbo S4 T2 Engine and N333 ecu?

Could i use the N333 ecu to run a non turbo S4 T2 engine?

Every part is from a S4 T2, uim, lim, tb, injector, engine harness, afm etc just minus everything turbo related.

Or whats the best way to NA my T2 engine?



Thanks

you will have to plug the oil feed banjo bolt on the front iron (M12 x 1.50 ? might be 1.25 pitch). you will need a split air blockoff plate for the coolant feed on the LIM, a cap for the coolant return port (on the water pump housing) and then you may have to get a custom blockoff plate for the oil return line on the front cover. Use the gasket as a template and cut out some aluminum or something. Or you can get one machined.

Then you will have to find an exhaust manifold. You can use either a factory manifold or an aftermarket header of some sort.

The ECU will be fine; it's the mechanical aspects that will require modifications. A turbo engine spends most of its life operating under vacuum, so there's no reason to think there would be a problem if it never saw boost again.
