Anyway, I think everyone needs to consider the repercussions of a turbo kit on these cars for the long term, whether it be racing or daily driving. I don't sell Speed by Design and it makes no difference to me. I'm trying to give peoe a heads up based on a lot of past experiences I've dealt with on my own cars and 100's of customer cars.
For example, the Ralliart I drive is turbocharged and Mitsu cheaped out and didn't put an oil cooler. Albeit these cars run at 20-24psi, I've had at least 10 busted turbos and a handful of lifted head gaskets because of oil temps getting way too high.
I just don't want people to have problems long term and an oil cooler is really a no brainer when it comes to turbocharging.

I don't see the correlation between boost pressure and oil temps, but if you've busted 10+ turbos, then the cause of the problem hasn't been addressed.
I run my personal car with 260-280F oil temps, and have yet to have an oil related failure. In fact, I have an oil analysis for every single oil change on my car, showing that I'm doing just fine with those temps. I even run 10k oil change intervals. Of course, YMMV.
