I prefer the 1g non-turbo throttlebody for a couple of reasons:
- Omission of restrictive elbow
- 3 Vacuum ports as opposed to the factory 4
- Offers the most flow of either of the DSM throttlebodys
The only drawback I can think of is reconfiguration of intercooler piping, otherwise if you can locate an NT throttlebody for relatively cheap then I'd suggest to do so. However, from a performance standpoint I didn't notice much of a difference despite the CFM increase albeit I am still running a factory turbo/intercooler.
