    Iv been told the 308 and 304 cast exhaust manifolds are the same so this is very possible that I have most of the pieces needed already.
    Buick even used the quadrajet that's currently fitted to my engine. suck thru would simplify the processes by not needing boost compensation/reference power valve too which is nice and I can use the factory 304 intake manifold

    Sounds feasible

    Using the 304 intake manifold injector holes for methanol injection would be piss easy too and negate the need for an intercooler
    Sounds more and more possible the more I think about it

    Surely a VF52 off a subaru would be better than a cheap TD04.

    Both would be too small I think
    Tdo4s are 1.8l gsr turbos and a subi turbo would be perfect for my 1kz
    I'd need to do a twin turbo set up with them to get the 308 cu level of flow required
    I had a tdo8 as a teen I can't find that would probably be perfect with a rebuild but I'd say a new Chinese turbo woul be cheaper than bothering and would have the t4 flange which is easy and low cost
