The biggest hurdle I can see from looking at the specs, is that the HB13 is an 1800cc with a proprietary Nissan Fuel injection system, thereby having a computer to control it.

Where as the FB13 is a 1500cc with the standard Electronically controlled carburettor that was standard at the time. Not really much in the way of a computer/ecs.

Not sure where you live or the regulations there. But the HB has Front and rear disk brakes, yours only has the front disk and rear drums, you'd likely have to upgrade your brakes to deal with the increased Kw/Hp's.

HB - 102Kw.

FB - 69Kw.

And frankly if you are going to go to a fuel injected engine you may as well go to the next in the series as the Hb is a SR18DE: D = Dual overhead cams. E = Electronic fuel injection. And the next best one is the

SR20DET: 2.0 Lt, D-DoHC, E- Elec Fi, T- Turbo.
