Great weekend a couple of weeks ago at The Circuit of The Americas in yellow solo group. The second to the last session on Sunday I saw smoke coming from the rear mirror. No check eng light, but pitted and realized it was coolant leaking. Had the car towed back to San Antonio and turns out the passenger side turbo has a coolant line that is mostly hard pipe and then rubber, it burst at the rubber part where it connects to the turbo. The car is 16 yrs old with 54k miles and a AWE 750R kit. I mostly run 93 and do not go to the race program with race gas. I'd say the car is 50/50 street/track. My local shop says it's a motor drop job and I'm thinking the other line on the passenger side also should be replaced at the same time. I'm also wondering about sending out my cams to be pinned though I have had no issues thus far.

The coolant lines are already pinned with the shark werks parts many years ago. It's been over 4 years since plugs/coils and belt have been done so I'm thinking that too. Still have the hydraulic assisted clutch with a Sachs 2 unit that probably has 45k or more miles on it so thinking of that. Wondering if the gt2 slave conversion and getting rid of the hydraulic assisted clutch part would be good?

What else should I be thinking about and should I just chalk up the leak to age of the part and heat? Or should I be looking for something else? That weekend was low to high 40's temp wise fwiw.

I'm being told the new lines won't be in until next week sometime.

Thanks!

 

You basically hit everything that would be on my list. Plugs & coils are a must. Given miles I'd definitely refresh the clutch disc while it's out. Personally I'd skip cams, but I plan to do a motor build if I run into that issue so if you would just end up doing the same if they failed later I would go ahead and do them. I regret not doing a GT2 slave when doing my build, so I'd do that too. Not necessary but RSS motor mounts and fresh transmission mounts wouldn't be a bad idea given age, power, and miles.
