Re: [doc] Engine "faff"?

["andrew986186" <andy@xxxxxxxxxxxxxx>]

soo much tech talk, heads are spinning
im hoping for 330bhp(stage 2) for starters
easily achieveable from the cosworth YB with a remap, stronger 
actuator and larger injectors
then we'll see where we go from there
low comp pistons and forged rods are winging their way to me
still waiting for the illusive bellhousing  

(I can feel the tutting and head shaking now.....purists beware, its 
my car and i'll do what I like!)

Did a few hours on the underbody today, just getting over flu so 
didnt really feel like working on other peoples cars, they can wait 
till tomorrow! and besides all this talk of high bhp D's is making 
me thirsty, so im gonna steam in now.
