By the sounds of it you're going to be selling this after you're off your p's so is it worth spending all this money when you're just going to lose it in a year when you sell it?

If I were you I would keep the ute as is until you're off your p's and save the money you're going to spend on the engine for your next car.

Otherwise spend the money and convert it to CA. You'll get 140hp a whole lot more reliably and you'll have scope for more power down the track whereas with the Hypo A15 you will have already developed it nearly as much as you can (at least for a street car.)

Just my opinion
