Default Finally....the GS is back together!!!

Over a year ago, I dropped the ZF out of my GS to do the clutch. Then I thought "You know, the engine would come out easily now so I could clean and detail it" Well, you guys know how this story ends. One thing led to another and my 'clutch' job turned into a complete and massive rebuild from stem to stern. I finally got it back together on Monday after having it on jack stands since January of 01.

Here is what I did:

Poly bushings throughout
Powder coated various chassis parts
New springs front and rear
Earls stainless brake lines
Installed cross drilled rotors
Clean and repaint bottom of chassis
New Goodyear GSC's
Exotic Muscle harness bar (the best)
Grand Sport sill plates
Wet Okole seat covers
APC reflector headlight housings for H4 bulbs
True HID headlight system ($750.00)
New u-joints on drive and half-shafts
Hurst Billet shifter, stock ****
Replaced all transmission seals/gaskets
Installed skip shift eliminator
Brand new flywheel (ouch)
Brand new Luk clutch disk and PP
Installed new starter
Tore engine down to short block and repaint.
Replaced all engine gaskets and seals
Painted and powder coated various engine parts
Installed LT4 hot cam
Installed ARP head studs, ARP fasteners throughout
CNC ported heads, extrude honed intake manifiold
Hooker short tube ceramic headers (copper gaskets)
Left the cats intact
New fuel filter
52mm Holley Billet TB
Holley billet fuel pressure regulator (the best)
K&N, open lid
Flowmaster American Thunder exhaust (welded, no clamps)
MSD 8.8 wires and Accel 300+ ignition on stock coil
Spectre stainless hoses and Magnaclamps on all fittings
MAD underhood light switch kit

After everything was all done and checked three times, I set the initial fuel pressure to 45lbs and climbed into the drivers seat to start it. I sat there with my fingers on the keys for several minutes....nervous..... I finally turned the key to on, heard the the fuel pump build pressure, and hit the key. It fired up on the second revolution of the engine and settled into a 1400 rpm idle!!!

It threw a code 64, which is the TCS system seeing the TPS not being set correctly at idle. I let it run for 15 minutes then shut it down and adjusted the TPS for .55v at idle. Cleared the code. No further problems.

There are no fluid leaks, vaccum leaks, and no odd noises. I am still amazed that I pulled this off with no major problems.

I am surprised that the Hot Cam has such a strong lope during idle. It really sounds mean with the Flowmaster system. The car is much quicker than stock, the difference is night and day. I had the GS dyno'd bone stock and it was putting out 305 HP to the rear wheels. I cannot wait to see the numbers now.
:D

It should put down some impressive dyno numbers. My car put down 270 stock and 313 with the hot cam and stock exhaust. Now with my headers and exhaust work I make 336 hp and that's still on completely stock untouched heads!

When I get some CNC'd heads on there it's gonna be a beast. And yes the hot cam does have a nice healthy lope to it doesn't it? I've got some sound clips in my sig. Pulls like a bat out of hell from about 4000 rpms up too.

gsvette,
How rewarding does that feel!!!!!!!!!!!! i have a few down right now.. but gosh everytime i finish one.. it is completely detailed as you said and i usually dim the front shop lights and just sit and stare at the motor compartment in complete awe of how clean and nice the work and end result is.. i usually sit for a about 10-15 minutes.. then crank them up and roll them out.. i am always sad to see them leave.. i kind start to feel a part of each vette i work on.. they all have personality under the hood and some are stubborn some are pleasant but they all look the same when im done.. BRAND NEW! congrats i am sure your very very excited.. the hot cam is a beautiful bump stick.. and yes it certainly has some character to its idle. glad to hear you got the code straightened out. and for god sakes post some pictures all that work you need pictures to remember what it looked like when you finished.. they never stay that way long!

congrats!!

chris :cheers:
