Schwitzer T04B 61 trim turbo

[bOOstd GSX]

I just got a brand new Schwitzer T04B 61 trim turbo and a cast manifold and I have a few questions:

1) Will my car run properly with just the safc or am I going to have to dsmlink v2 or some other engine management in order for it to operate properly?

2) What wastegate shoudl I go with and what spring pressure?

I am used to having internally gated turbos and don't know much abotu this new world of externally gated beasts.

SOMEONE PLEASE HELP!

You list no other mods, and if your asking if just a s-afc will work im assuming you have no injectors or fuel pump. In which case, your not ready for a turbo upgrade IMO.

S-AFC can control 660cc injectors fine. With a 50 shot and 60 trim you might need to go with bigger injectors though, in which case DSMlink would be a good idea.

About how much bigger do you think? I was thinking 880's or would 770's work?

 

[anconover]

im not sure id wanna spray a 50shot on top of high boost on pump gas, but. Your obviously already controlling your injectors with the s-afc so... Personally if your funds can afford it, get dsmlink no doubt.

If you're willing to get DSMlink then get 880s. You can in theory control 720s with an S-AFC, but your timing will be very high so I don't reccomend it. Some people also have trouble getting a good idle. And like Anconover said I wouldn't spray unless you are running race gas or lower boost. Start at like 15 psi and work your way up.
