GTS Resurrection

The only new plated parts that I can think of were the FPR and dampers. Some bolts are probably new, but everything else was replated. Not sure who Greg used for the plating.
Here is the engine ready for the test stand. It looks incredible.
The powder coating on the manifold and valve covers wasn't in great shape, so I had it redone, along with hardware plating.
I had done an intake refresh just a couple thousand miles ago, so we were able to reuse some pieces - Hall sensor, knock sensors,CPS, injectors, etc., but most wear items are new, including the 14-pin wiring harness, fuel pressure regulator and dampers, oil pressure sender and spark plug cables.
I really like how the powder coating came out on the manifold and valve covers

Which hardware parts were replated and which ones are new? Who did the plating?

I’m just curious about intake and exhaust durations, are they more like what Colin/Colt profiles are or more like what Porsche profiles are? Also, are you running straight lobes on flat lifters or stock tapered lobes on stock spherical (very large radius) dome lifters?
#51
These are not what I would design for lobe centers or lobe separation, but they are not my product and everyone has their own ideas. These cams add a little bit of "punch" over a stock GT cam without making the engine "dirty" or killing the bottom end torque. The material and quality is very high and unlike all the Porsche factory cams....they are both available and economical!
Standard style lifters. I use a special lightweight DLC lifter (not like what Colin uses) to keep the spring pressures as low as possible....something very important to me, over my entire career.

Standard Colin Stage 2 cams. These are "Colt's favorite thing to do"....dual intake profile. (That's an entire subject/discussion on it's own,)

Keep in mind that I run new DLC lifters, which are very "lobe friendly" along with very conservative spring pressures, so I may not see compatability problems others may experience.
#54
There’s probably no issue running the stock spherical lifter on non-tapers lobe either, but not sure about that. Just curious about how significant people think these minor variations are.

It's Alive!
I've been remiss in my reporting. Over the last couple weeks, the following has happened:
Greg got my engine running on his test stand. Started right up, and ran fine for about an hour total. Just needs a little tuning.
I tried to post a video of the engine running, but couldn't get Rennlist to take it.
Then he installed the engine back into the cleaned-up engine compartment. A bunch of new stuff went into the engine compartment (some of which I had stockpiled):
- Clutch pack and flywheel
- 14 pin electrical harness
- PS pressure hose
- AC hoses
- Clutch master
- Rebuilt clutch slave
- Oil pressure sensor
- Coolant reservoir and hoses
- GB alternator
- GB fuel lines and oil cooler lines (installed shortly before engine failure)
While installing the engine they found two problems:
- One cooling fan was barely running, causing the other to run constantly. Greg replaced them both.
- The AC condenser had a hole on the underside, apparently from corrosion. Not sure when this happened. I'm sure the AC worked the last time I used it, but not sure how long ago that was. So Greg found a new condenser, and replaced the compressor at the same time (He said Denso is practically giving them away.)
With those problems resolved, the car is now back together and is currently being road tested!

Thats the money shot, lots of fresh parts in that engine bay.
This is the best way to breath new life into a super car.
The West Coast guys at Gregs shop do very nice work.
Your fortunate to have this car fixed their and so is the car.
Keep em flying!

Excellent thread and details. I always love a good salvation story. Congratulations to you for your GTS resurrection! Let's get a look of the whole beast.
EDIT: I missed the post with the photos of the car. Beautiful combo. Love it!

Glad to see you are back up and running. IIRC there were around 11 Amazon green GTS's made and only 2 I believe with 5 speed box. Mine is the other M with cashmere interior. I believe and don't want to speak out of line so correct me if i'm mistaken. Back when I was searching for my GTS I came across your car and there was a bit of controversy over the actual miles. Not sure if it's so but was told the later cars with electronic odo can be checked to see if any odo tampering had occurred. Might be worth checking. Would be interesting to see if this is age or mileage related.
Looks like it will be better than when you first purchased it. All the best and fun driving.
