Im going to pick up a 1999 firefly 1.0 5sp 190.000km for $800 and ive been thinking about getting a 3 tech head package with cam. Are these hard to install and tune? any special tools needed? Thanks! |

Well, if you are going that far, don't skimp out on the bottom end. I highly suggest getting at least new piston rings and re-ringing the pistons and honing the cylinders. It's only a couple more hours of work once the head is off. Since you have a 1999, then all you need is the head package and also get a 10 degree advanced timing gear. You can get an economy grind cam if you do city driving and prefer a lower power band, otherwise use a stock cam. You will need a head gasket or a head gasket kit to complete the job. Would not hurt to slap on a new timing belt also. Please read this thread regarding head and oil pan gaskets..... http://geometroforum.com/topic/1987137/ And here are a few threads to help you on the head removal.......... http://geometroforum.com/topic/638797/ http://geometroforum.com/topic/2175380/ Good luck and you will not be disappointed

Sounds like a good deal, Grabowski. Post pics when you can, please? Only "special" tools might be torque wrenches. Without my Chilton in hand (I'm at work) I know the cam bearing bolts are in inch pounds (97 comes to mind) and I'm sure the head bolts are foot pounds. Harbor freight is OK for quality but most prefer the Snap-on or Craftsman quality tools. |

You can buy or rent a 3" berry hone and hook it to a cordless drill. Add some oil to the cylinder walls and hone them with an up-and-down movement until you get the desired crosshatch pattern. |

This is one of the easiest builds there is. Relax, we can get you through this. Trust the Mullet. And check that oil passage on the head gasket. I did mine before I found this site. Now I will have to go back in or improvise. |
