Not sure what your putting the engine into, but sounds like a 7M-GTE would be a good option. With good engine management they produce great power.
Sounds like you have a 7M already, so a 7M-GTE should be a drop in. Pick one up cheap. Reco head and gasket, drop her in. Then you'll have plenty of cash to spare for management down the track.
Talk to SupraGTE from this forum.
