The Anglia makes the same power as it would on the standard injection and a new exhaust manifold and is less efficient than it would have been then?

As I thought, youre budgeting for buying a TB setup when you already have carbs. Go and add up the cost of your new 45 setup against that of throttle bodies at the point the OP is at (has engine and no inductions setup) and use new prices to keep it fair since thats what youve done with the TBs (good injectors can be had for £50 a set for instance and any scrapyard efi pump will suffice for 200bhp.) and you'll very quicly find the cost is almost identical.

You won't build a tested megajolt unit for £100 the way the exchange rate etc is now and like i said, the 25 quid box is a bodge and a poor one at that. The new carb is cheap, but once again no better than a standard inlet!

Like I said above, you can do it right, or do it cheap!
