I have a 5k in my kp61, its running a 40mm dellorto sidey, lumpies, p&p and the rest of it. i was thinking of building up a nasty lil 4Age turb's to slap in it but i get a this 'nah stick with the 5k' shit....... Why, give me sum reasons and i may think about it.... I need power, not uncanny masses of it but u no, maybe a 11-12 1/4 as it already does a 15..... Help
also i recall someone saying something about 1g pistons or sumthing fitting in a 5k....
