350HP930

Well after 5 years of ownership and about 130,000 miles (70K of which are mine) I have recently dropped and broken down my 930 motor for a complete rebuild. I was hoping to put it off a bit longer but the starter ring gear lost a few teeth so the motor had to come out anyways. Its been needed a rering and reseal for a while.

Thanks to recent economic trends I will have to pull off my rebuild and mods on a tight budget. Fortunatley have access to a high end machince shop and porsche dealer service area due to my employment and engineering backgroud (BS in Aerospace Engineering, U of F, Class of 95) so I do not need to pay for anything but parts and dyno time.

Here is what I am planning on doing to extend my existing mods. I would appreciate any input people would like to give me on my project.

All the hardware looks beautiful except for a mild scratch in one cylinder. Everything mics to about 0.0005 of factory specs.

For this reason I am just going to rering the cylinders. I am seriously contemplating going with gapless rings.

Here is a list of most of the other stuff I have on my todo/toget list.

ARP rod bolts
993 Turbo head studs
All harware flycut and/or lapped and rods resized
New bearings and gaskets
New chains and tensioners
New valve guides, exhaust valves, keepers and valve job
New mild performance cams, rockers and rocker seals
Slight compression bump
8:39 Ring & Pinion
HKS AIC III (Supplemental Fuel Injector Controller)
HKS EVC IV (Electronic Boost Controller)
Boring and Porting the Heads, Intake and CIS Plumbing
Thermal wrapping the exhaust
Polish the fan
Combo EGT/CHT guage

My current spreadsheet for my project shows that the total cost for all this will about $5K, with $2K of that currently sitting around in boxes.

I figure I have a few months before I will have all the time and money I need to pull this off.

I look forward to the wisdom this board is sure to bring me.
