My estate diesel has the stage 1 remap + egr delete so when the turbo kicks in it actually pulls pretty well. The torque is great and power is smooth through the rev range, this is coming from someone who's been driving an accord type r for the last 3 years. I do miss the old atr though :(
I've just ordered a battery for my diesel from Holdcroft Honda for £45, i can't see why you should spend over £80 for a bosch one, its not like it adds 20 more bhp lol
You'd have to spend a lot to get 250+ na power from the h22a7. Speak to andy at vtecdirect as his race car is now running more than 260 if i remember when i met him last.
Otherwise turbo or supercharging would be your best bet, but the only thing is it doesn't work well on the h22a7 but does in...
God knows but the pedal i'm told by others is ultra stiff. I can't tell cos i'm used to it, the clutch pedal movement is really short and stalling is a common thing to those who drive my car lol
