Either use the 5sfe/3sfe tranny or get a custom exhaust manifold. If you can weld, it would not be that expensive a lot of guys on here make there own manifolds. Maybe you could get someone to make you a manifold or you could borrow their welder and make your own. Actually now that I think about it a custom exhaust manifold is the way to go because the 3sge tranny on your car has better gear ratios than the 3sfe/5sfe tranny's plus the custom exhaust manifold is gonna flow better than the stock 3sgte one.
