hehe... Yeah, the "delete" was completely unintentional. I was cleaning house of all the M96 parts I had in the garage during the swap and I just tossed the triangle thing in the trash not thinking it was structurally important. Before I had the swap done somone on here made a post about how it was important, so I made due. TBH I don't think the original would fit around my transmission cradle.
The blue text reads "this is a suplemement for the transmission "triangle" Its just extra bracing". Sorry I'm hopeless when it comes to pictures and media.
Oh man, I saw V8 and ran to a V6 LOL... But I saw the limitations on the 5 speed trans and I wanted a roots blower*, so I made the V6 decision. Also, all my accessories and everything engine wise is 100% GM; so parts purchasing and replacing stuff is totally off the shelf easy. *a top mounted roots blower wouldn't be possible on an American V8 in a boxster. So I wouldn't hold myself to doing anything particularly challenging, I just put an engine in a hole. American V8 seems to require some effort.
OP: are you going with E-power steering? If it was me I'd make a power steering pump from like a Camry fit and mount it on my left cross member. The Left side of the engine bay is like 100% baron compared to the right side. The right side has all manner of coolant hoses and whatnot. I used the extra space on the left to mount a small oil cooler.
Speaking of coolant. I don't know, and I don't think that it matters, but the pressure ratting on the boxster cap is 22psi and most GM 90* V blocks (V6 or V8) are ratted at 16psi. I've seen other V8 swapped boxsters run the OEM coolant tank, but that did concern me enough to swap to an aftermarket expansion tank with a 16 psi cap. The extra pressure is clearly there to raise the BP of the coolant, but IDK if that is what GM had in mind when they engineered the engine. Seemed like the best idea for me just to go ahead and swap it over before I ran the crap out of the engine. YMMV
^^^ Yay another terribly blurry hopelessly complex picture of the underside of my car. lol
But I did forget to mention that I did NOT go 100% the same route as the Australian. My subframe bolts under the car in the front. There are two VERY large 1/4" backing plates under my carpet under my seats. That's where the front two arms of the subframe connect to the vehicle.
You can see pretty clearly in the picture that if one was to put a V8 in there with an almost flush harmonic balancer you wouldn't have to move the engine/trans too far back. As my accessories have about as much length as an extra cylinder would measure.
