940 & 960 Need opinions on exhaust manifold of RWD T4 build
I need to hear some opinions about the exhaust manifold options on RWD T4 whiteblock setting.
Stock manifold does not work, I thought I could flip it and be all good, but then the holes wont line up.
Full custom job is too expensive for me, but I thought that maybe I could buy an aftermarket 4cyl rwd manifold for some other engine and weld it onto a T4 exhaust flange.
What do you think? Is it impossible or are there some common engines that have similar bore spacing?
I have done some research and found some possible options
- Miata 1.8 turbo header, (bore spacing 91mm) cheap and correct spacing, but has incorrect turbo flange.
- Log manifold DIY kit, super cheap but more work needed ofc, and I dont know about performance and looks.
- Nissan SR20 header, (bore spacing should be 97mm) super cheap and with correct turbo flange, but probably need to cut off the block flange, heat and bend the tubes a couple of mm and reweld on a whiteblock flange.
