What size injectors do I need?

[jkimes]

I need to purchase my fuel system upgrade parts so that I can install them before I bolt on my new turbo and I need some advice on which injectors to use. So far my setup is as follows:

Re-Built engine with JE pistons and Crower Rods
K&N style intake
3" powdercoated downpipe
custom 3" catback with N1 muffler
Manual Boost Controller
Autometer Boost and EGT guages
1G BOV
Upper IC pipe
Eibach Pro Kit springs
Tociko adjustables

I just purchased a new PTE SCM61 56 trim turbo which I plan to support with a Walbro 255 pump and DSMLink as well as a big front mount IC, but I have no Idea which injectors to use in order to max out the turbo and tune it properly.

Any suggestions would be greatly appreciated.

Thanks

i would go with 720cc to keep the injector duty down

Do you numbers on these calculators. It is all up to what you are looking to get.

WHOA.... hahaha I am not worthy I am wrong.

not to jack a thread but my brother is doing a KADE Turbo conversion and is getting a T3 60 trim what you think he needs?

I say 680s would be sufficient.

680's on a 56trim turbo of that sort will NOT be sufficient. That is a 600+hp turbo. You should atleast be running anything above 8--'s.

If it were a 50trim that would be sufficient.

That is a huge turbo to be playing "guessing on ideas" with. Be sure you know what you are getting into.

I am not doubting your skills in tuning or driving. Just letting other know that the turbo in your post is pretty huge comparative to others most are looking at.
