Make sure you can get lots of parts. But not a good idea. Not sure how available parts are for these old engines.

If its not been done before we need you to do this and record everything to here, YouTube and Facebook. Not too much that could go wrong surely?

Giggle gas is never safe. Even when handled by "professionals". You see cars go up in flames and throw parts halfway across the race track even under "professional" use.

 

The least that will happen is that you will yardsale that poor EA81. If you are unlucky you might also set yourself and the car on fire.

+1 At 150K, it's a bad idea. On a fresh engine, IF you studded the heads and had an ignition control system to run the timing along with methanol injection, it should be ok with a 50 horse shot. The engine will surely yardsale under current mileage and configuration as GD pointed out. You can't build power from an EA81 without knowledge and experience, and even then, you're still limited by original design.

Nitrous is cheap power. If done right.

You must have the proper ring gap, timing and wet system. Or you'll just blow it. 

Plus, with the small displacement, low compression and lack of fuel, 50hp shot would be more like a 10hp shot.
