Hi Conrad,

I'm sure my car will love the company of yours when it arrives down at RS.

Do you have any photographs of the lightweight bonnet you have ? I need one. I've steered away from the drop vented style of bonnets as the F20C motor is a bit longer than the 4AGE and it may not work. If its an upwards vented bonnet I could be interested.

With regard to the ITBS - they wont really give a huge improvement at the top end of the rev range - but they will make significant improvements in the mid range.

My friend just engine dyno'd an F20C with the same Jenvey throttles I use and it made 247bhp but more importantly 187lb/ft which is quite a bit up on standard. The torque was mainly obtained by increasing the length of the inlet tract AFTER the ITB by using spacers between the throttle body itself and the inlet manifold. Mid range is really where you see the improvement. If you look at the graphs on the Jenvey site you will see 30+bhp improvement increases in the mid-range.

I got the Jenveys knowing full well they wouldn't gain a huge amount on a stock engine - but they are things of beauty and will sound superb (not that stock F20C engines sound bad).

In the future if serious work was done on the in/ex ports and the addition of cams (possibly evening removing the VTEC system completely) they will help a huge amount.

Congrats on getting your conversion under way.
That means there is 100% 3 F20C powered 86's in the mainland uk.
