Are piggyback units such as the Greddy eManage or AEM FI/C really necessary for boosting the 2.4L engine on the TC?

even if I don't use massive injectors, can i run without a unit under safe boost like 6-9psi...im using a Saab t3 turbo. not looking for huge gains...maybe 250hp by the wheels 290-300hp at the crank.

Someone help me out here on this? I want to start gathering other parts for my custom turbo kit..

 

You can try to get away with no piggyback but your motor won't last without one on the PSI/power level you are looking for.

If you go for a 200-220 range on no more then 6psi and stock injectors you could get it to work but it might run a little rich.

 

what if I find a larger set of injectors close to 440cc?? does it make a difference..what do you recommended as a inexpensive piggyback?

 

I think anything bigger than the stock will make you run way too rich without a piggyback.

An inexpensive piggy back is a the emanage basic aka blue. It will probably be the cheapest out of all of them and you can always buy a used one.
