Hello, new member here. I don't currently own a Porsche but am planning to purchase one in 3 to 6 months. I've decided on a used cayman. After reading about the 100hp gains made possible with the TPC LP turbo kit, I'm thinking that, combined with an inexpensive used low miles cayman would be the best performance per dollar out there.. In theory. My question is which model year, and to S or not to S? I'm not planning to do any track driving, I'll leave that to my sport bike. Planned use is as a second car to get more enjoyment when I have to drive around for work as well as spirited excursions up and down the local mountain passes. I live in Reno, NV which is at 4500', and tahoe gets up to 6300' real quick. I can tell you that altitude has a major effect on my bike, and I'm sure the cayman will be the same. Hence my interest in the turbo. So one school of thought I have is to get a 2006 cayman Base. Those can be had for the low 20's, add the kit and I'll be in this under 30k. I have read somewhere that the 2009 and newer engines are better suited to a turbo addition, but I don't recall the reasoning. I've also read that the tiptronic causes some extra hassle with the install so will plan to stay away from that. For another 5k I should be able to get a similar S model. As a final thought, how reversible is the turbo install? I'm thinking I will do the bolt on myself, but I have not fully researched this yet. I'm asking this last part to understand if it would be feasible to remove the kit when I sell it in a few years to upgrade. It seems like I would be able to get more return selling the kit separately when the time comes. Anyway, thanks in advance for any wisdom shared.
