i also posted a thread in the mods section as well. This thread is being written to everyone out there with an MX6/Probe with the 2.5L V6. When this engine was produced it was praised by all of the major car publications as the best in class motor built. It still is to date. SCC and Turbo magazine had there fun with our vehicle around a year or two ago. They tackled every aspect of the vehicle that should make horsepower when modified and came up with nothing. After a few installments they dropped the project because it was to costly. There is no cheap horsepower to be found with the KL-03 engine. A $600.00 Greddy exhaust will give you 2-3 HP, where as an intake of anykind will give you 1HP. Putting headers and reprogramming the ECU can cost another thousand dollars for maybe 4-5 HP. The fact is there is no way to make real recognizable horsepower with that engine. The great thing about that is since it will cost you around $10,000.00 for a KL-ZE engine with a stroker kit from Probe Industries, and a TKT twin Turbo kit. We all know that there are not that many Probes/MX6's in the country with those king of modifications done to them. Our engine with the proper, costly modifications will run between 400-650HP. You are talking about a $25,000 investment in just the engine and the management of it to make that kind of horsepower. Just ask the pro's running 600+HP with their Honda's how much of an investment they took on there car. When that figure is said make sure you are sitting. 9 and 10 second Honda's at the track cost a lot. I think that our car has a lot of potential. For all the owners out there, hang in there. Talk to you soon.
