dudes, i have an SR20det black top under the bonnet...hehehehe
with the exhaust it runs about 10psi, comes on at about 3000 and sort of fades at about 5000rpm.
i have races other 180's and silvias and they cant seem to get past me. but i got smacked on the knuckles by a worked up toyota gt starlet by half a car length, no matter how hard i tried i couldnt get past his front wheels. we were doin about 160km in a 80km zone. it was fun though, i reckon i could have taken him if i got to 5th gear... there was also too many cars around and traffic lights and tight lanes..(excuses, excuses, i know but i reckon its true..)
cheers
