I have a '84 Mk2 Supra with a 1jz, and been looking into aftermarket intake manifold kits that include TB and fuel rail Power gains likely very modest for me, but they do look nice and cleans up the engine bay. I like being able to get to the injectors easier too. Thing is, don't see much posts for this mod, so wondering if they don't fit well, or really is a waste of $$ for meager power gains. Anybody done this?
