what sort of power can you get out of a 1st gen without changing the engine?

All depends on your budget mate.  They make bugger all as standard with all the emissions gubbins on.  Put a big bore pipe on and a 48 webber should get about 135bhp.  They feel much quicker than the power would suggest tho.   My standard, apart from exhaust & filter, jobby always put 130 on the clock.

I know yu can get over 200bhp with the jap turbo + injection set up.  A few grands worth tho.

I got  an Elford turbo kit for 500 notes and that should make 170bhp no problem.  It goes on the rollers soon to find out for sure......

My first gen has a Turbo II engine and gearbox in it. That makes it go well:D

Tim\'s (RX Motors) Gen 1 is a 12a engine - ported admittedly and running a GT35/45 turbo at about 350-400 bhp I believe. 3rd fasted Rex on the quarter mile in the UK!

i\'m sure Racing Beat manufactured a carb kit for the 12a that could put out 280hp,i\'m afraid i don\'t know any more about this,and could be very wrong.As usual.
