Really nice write up and congratulations on achieving your 11 second goal, but may I ask what was your motivation? Looking at your sig, was this your most recent combo? I see you have a couple of others listed. No offense, but it seems like a lot of work and down time to go slower.
what brand are those long shank carbides? man those are hard to find.In my quest to run 11's on the stock turbo, intercooler, and converter, I'll be port and polishing almost everything but the heads. Here is the thread with a great wealth of information about how to achieve 11's with my combination.
http://www.turbobuick.com/forums/ge...11-s-stock-turbo-can-t-get-car-go-faster.html
Here is the list of things I'll be porting and polishing:
Stock upper and lower intake
Throttle body
Intake ports on the heads
Stock exhaust manifolds
Manifold to turbo
Compressor housing inlet and out let
Turbine inlet
Intercooler neck
I've read for hours and hours here and other boards on porting techniques and theroy. I want to thanks VadersV6 for all the help he has givng me and answering all my questions. I quickly learned not to just hog everything out, but to create some velocity in the lower intake and heads. I don't plan on pulling the heads on the car.
I'll update the thread as I work. I figure it will take me a few weeks doing all the work on weekends and after work. If anyone has any recommendations or critisism along the way, please post.
I'll start off with some pics of how the engine bay looked before I tore it down.
So far I was able to get everything off other then the lower intake and the exhaust manifolds. Only took about 3 hours.
Here are the pics of the engine bay with the parts removed:
And here are the tools I'll be using. I got the carbide bits and the head porting kit from Summit, the Grinders grease came from Eastwood.
I may polish the outside of the upper intake if I feel up to it.
Other then porting the stock turbo's wastegate hole, I've never done any porting or polishing work, so please bear with me.

well, I did mine already. What a difference! I definately would love to do another set even better than the last. so I'm in man.Just search duckduckgo.com for "6" shank carbide burrs". Many many sources. Even my local fastener supply house has them in stock, but pricey. It's real easy to sink thousands of dollars into electric grinders, router control boxes (to vary rpm speeds Wich is a MUST HAVE item if head porting). I use to use a light dimmer switch that worked very good for cheap if you know how to wire a electrical box. A good face shield, good hearing protection, and good respirator. I have been porting heads for over 30 years and have taught a handful of guys how to do it. EVERY LAST ONE of them told me that after ONE set of heads that they would NEVER, EVER do THAT again! LOL. I would love to mentor some young person on how to do it, but most people just don't consider it an "art form" so to speak. I listen to music and it ore the whole world for hours on end. Better have a nice warm shower available when you quit for the day to clean up and sooth your arms and shoulders. A hot tube would be better. (I think). Good luck giving it a try. PM me for my phone number and we can chat for hours........
