There are so many things wrong with this topic I don't even know where to start.
To clarify, you have an s52 in your car. From the looks of it you also have the m50 intake manifold. I was wondering why you only ran a 13.8 with a s54. The car you ran against did a 11 second pass. What was it?
Your e30 is beautiful. Love it.
DINAN doesn't make a turbo kit for the e36. They have superchargers, that's it. To turbocharge your vehicle would probably run you close to $6k-$7k. You would put otu about 400 rwhp. Technique Tuning is teh place to go. Get a stage II kit.
You spent $12k on an s52 motor?
