http://www.geocities.com/bustacasey/porschev.htm here is an example of 912 v8. I bought my kit from Renegadehybrids. I have a 901 trans but not sure about how long its gonna last w/ my chevy 4bolt L82 w/ chevy fastburn alum heads, edelbrock airgap intake ~425hp, already saving up for a 915 trans. Welded turbo flares all around w/ RS front and rear bumpers. Not really butchering the car per se, all modifications to accommodate the v-8 really apply to converting to a flat six w/ front mounted oil cooler. If I can figure it out, I will post some pictures
Here is an extreme example of a 914 v8 conversion. Little bit further than I wanna go w/ my 912...
