Firstly just like to say, I think im gonna like this site. Loads more info and more active than any other Honda forum I have seen so far.
Down to biz.
According to the chassis plate on my car I have an F20B3 engine. Which runs 137bhp stock, 0-60 8.2 secs. Not as fast as some of the cars I have had previously, notably my old slightly modded

Alfa 33 P4 cloverleaf (1.7 boxer, c/r box + 4wd), which ran 160bhp 0-60 4.9 secs. A real cossie/scooby/evo eater.
Neway Im after a shed load more power, I also want to boost n spray it. Do you guys think it would be better to do a swap or could I just use the h22 head (with a little modding). I meantioned the head because I read the article about the G23 frankestein engine build but am not sure whether this would be a good thing. Your advice would help a great deal as I know next to nothing about Honda engine types.
Im not after a race car or a street racer, Im building a full on multimedia car including carputer w/ 7.1 surround sound, air suspension and custom fibreglass dash, door panels, centre console, leather retrim etc. As you can tell this car is going on a full fat eat everything diet so is gonna but on a shed load of weight and needs loads more power to get it around.
What would you recommend to acheive 300-350bhp or as close as possible.
Thanks in advance
David
