Default built motor - now want to start it before dropping in car

I was curious if there was a way to start the engines before you drop them in the car. I know on V6s and V8s its fairly easy - less computers and everything but on these ones I dont really know as of right now.

anyone have any ideas or done it ?

thanks

I have done it with a Honda, but it was a real pita. The thing with a fuel injected engine is you have to have all the elements together for the engine to run. What I mean by this is either a standalone ems or the OE ecu with wiring harness, plus a fuel system that will work outside the car. It isn't like building a motor plate for a 350ci Chevy and putting it on an engine stand. CARB+Fuel+well that's about it lol. Much easier to do it with a carbureted car, but it can be done none the less.

The machine shop that biult my motor has an engine dyno but I didn't even ask if it was an option. I'd imagine things would have to be moved around a bit if it was even possible at all. Would be nice tho finding out if something wasn't sealed outside the car. Could potentialy save a lot of time and money.

well i know with the V6s and V8s (chevys, fords, etc.) all u need is a gas tank with some gas, and a battery, and a little turn key ingition - and the engine starts right up .....
i was just wondering if there was a similar setup for the impreza's or EFI engines.

carbs are easy hehe, less electronics.

It would be easier to fit a carb and a distributor!

Subaru complicates things buy merging the chassis harness with the engine harness. Most other EFI engines just need fuel pressure in the rail, B+ and ground to the ECU then it will start and run.
