I have finally started to get back to working on my 9A w/"alternative engine", and hope to have a first engine start in the coming months. I basically stopped working on project in 2008 due to lack of time and loss of interest, but I finally retired so have at least a couple hrs. / day to now devote to it on a regular basis. Last week I built up required -10 hose w/AN fittings to move the hot oil from the engine to a water/oil intercooler, and from there to the stock Mazda oil cooler. My plan is to pre-cool the oil with the water, and then use airflow to pull it down a bit more. This adds weight of course, but if the water oil cooler works well I might be able to eliminate the Mazda air/oil cooler...TBD.
