Hi,
Ok its a UK engine,
Micra_Mamp no it wouldnt be a simple swap as its coil pack engine and yours wont be a coil pack car. Could make it fit by swaping internals over to your block but this will cost.
Rob is yours a coil pack? if so yes simple swap.
Power wise the UK is 85bhp as standard, a standard Jap one puts out 101bhp
With a little work on the head and cams the UK one would be able to put out over 100bhp easy.
Price wise £300? If I get an offer of around that I could even do the head work and , might even make it so that it will run like a pre coil pack.
Let me know.
