Backstory:
September 2011, I’m running in a 2-day Time Attack competition. During my first timed session, on my second hot lap the turbo lets go.
The exhaust wheel shears off the shaft and flies halfway out my exhaust. Both my radiator fans melted. And the vacuum hose of my exhaust crankcase evacuation system blew apart from a failed exhaust check valve.
Towed the car home, shoved it into the garage, and there it sat for two years collecting dust while I played on iRacing.
Present Day:
With the National AutoSlalom Championship coming to my region next summer, it’s time to finally fix the Talon and bring it out of hibernation.
Compression & leak-down tests suggests that I have a burnt exhaust valve. It would explain the turbo failure and the overheating issues I was experiencing. So in addition to replacing the blown turbo, I need to rebuild the head.
The Plan:
First the turbo. I want something that will spool fast for autoslalom, yet produce good power for time attack. A Forced Performance 68HTA turbo looks like it’ll fit the bill nicely. It flows up to 51lb/min and should easily produce 400+HP to the wheels. A nice upgrade over my previous FP Big28.
Next the head. I priced all the individual parts to rebuild the head and the cost of getting Armstrongs (local machine shop) to put it all together, but quickly discovered that it’s really not a whole lot cheaper than sending the head to a highly respected builder in the US and have him work his magic on it. So I’m just gonna send it to him.
I’ll also get him to install a Kiggly Racing HLA Pressure Regulator, to help keep oil in the pan and prevent it from getting stacked up in the head.
In addition to the turbo & head rebuild, I also need:
- J-Pipe for FMIC
- Tubular O2 Housing
- Turbo Oil Feed & Retun Lines
- Prothane Motor Mounts
- Polyurethane Roll Stops
- Replace / Repair Radiator Fans
- Replace Melted Fan Connectors
I have an Mitsubishi EVO3 intake manifold sitting on my shelf, so I’ll take this opportunity to install that plus a 60mm 1GNT Throttle Body.
It has come to my attention that my Cusco Tarmac Center Differential is prone to failure, so I need to pull it out and inspect it for wear; possibly needing to replace it with a 4-spider OEM upgrade.
Also, I recently learned that my EVO8 rear differential is prone to failure with repeated launches, so I will also need to pull it out for inspection, and possibly install a TRE Differential Side Cover upgrade. Maybe toss in a Weir MAXGRIP LSD Kit while I'm in there.
And of course, there is my annual pre-season routine of pulling all the suspension off, inspecting and lubricating all the polyurethane bushings, inspecting all the spherical bearings, etc.
Then there is my Goodyear Eagle RS DOT r-comp tires, which are barely used but will be going on 3-years old next season and likely hard as rocks. They’re weren’t that great in autoslalom to begin with (being the road race compound), and will only be worse with age. So I’ll need to replace them with some fresh r-comps.
There’s lots more, but that is all I’ll list for now. I’ll post lots of photos and such once I get into the build.
To be continued...
