I can either go twin turbo or a single turbo... the condition on the engine is good. since i rebuilt it around 2 years ago. the only problem i have right now is bad valve guide stem seals and a rattle whens the engine is under load. I think maybe there is a loose lifter somewhere on the block and needs to be torqued down properly. im gonna go through it once more when i change the seals. I think it will be fine. But is the engine a low compression 3.0 v6 sohc 12 valve
