I've been picking my single brain cell about getting my old girl quicker, and for a change I am trying to be methodical and do things once, rather than cock it up, make the wrong choices are have spares and bills everywhere.
I was very pleased with the cars handling the other night, I carried about 85-90mph through Coram and with practice that would improve.
I don't want to spoil that unnecessarily, but would be willing to learn to learn to adapt if needs be.
My options (being sensible for a change) are
1: M20B25 engine and box, diff, 325 12v =170BHP , 175KG
2: M42 16V and box, diff =136HP, 132KG (lighter than my existing lump-just)
Thanks for reading/helping in advance........
EDIT
Found
http://www.letstorquebhp.com/calculator.asp and saw that the figures are wee bit optomistic

, but maybe the M20 is edging it...
