After having my 59 plate GT Cloverleaf for about 3 months, and having some general wear and tear maintenance work done on it with the Autolusso lads in Penrith, I decided it was a good time to get it remapped. Prior to the remap, I did have some concerns about the turbo due to an ever so slight scratchiness going through about 2,000rpm, the typical turbo whine seemed loud but I had read this was fairly standard on the GT's.
I took a punt and went ahead with the remap, but not even 20 miles up the road...bang...power gone, white smoke...
having been here before with my old BM, I knew straight away what had happened
Fair play to Dan at Autolusso, he came to recover the vehicle and took it back to the garage and, with about 2 litres of oil in the lower hose for good measure, my turbo fears were confirmed!!
I now have 3 options, potentially.
1. If the casing of the knackered turbo wasn't the point of failure and is in good condition, use this but have the inners replaced with a hybrid.
2. Buy a new standard Garrett turbo.
3. Buy a new hybrid turbo.
Has anyone else been in this situation, or has anyone got any thoughts?
My concern with re-using the existing casing is that it may appear to be ok, but may be already weakened slightly (£75k on the clock).
It has been sent away to the guy Autolusso use to do the hybrids for inspection. So I probably have a couple of days to make a decision.
I think I'd go for a new hybrid if I didn't go for the first option, not for performance reasons, but more for reliability reasons. If the hybrid can handle the extra power better than the standard off the shelf Garrett, then it's looking appealing. Or is it simply a case of the turbo being on its way out anyway, and the remap has sealed it's fate, and in actual fact a standard turbo is more than up to the job of a remapped GT?
Any thoughts would be much appreciated!
