Hello guys,
I have been researching for a homebrew turbo for my 3BII on my bj40. My engine came off a 1998 donor Dyna truck. I have a Mitsubishi turbo (D50 in USa) with 3 bolts and a Benz (300td) turbo with 4 bolts... both of them in my attempt to get the right one.
I live in Honduras, Central America and unfortunately we never got the 13bt engine as to get a donor manifold... but in my research, I went to the local truck wreck yard and came across an exhaust manifold off a 14b, which is exactly the same as my 3BII exhaust, I had the opportunity to mess with a pile of exhaust manifolds and compare them around. I found what they told me is an exhaust manifold of an ISUZU 3.9 Liter turbo diesel engine and went ahead and measured them both. In my opinion and the guy's from the wrecker helping me out, the two manifolds matched on their bolt pattern. Unfortunately at that time I didn't have any $ with me to buy the manifold and test it on my truck, but to both of us, it seemed like the ISUZU manifold will bolt to the Toyota 3BII head. Does anybody here has a way to confirm this? It would be great to know there are other options to the hard to find Toyota 13BT manifold.
Also, the isuzu one is 4 bolt pattern.
Just my findings on possible options for that homebrew turbo!! regards
