turbo choice....Help please
« on: June 12 2014, 09:51:40 PM »
Seeing that I need to replace my turbo, I was going to go with a 5931 from full throttle but started to think about it. With my current set up is there any advantage to going with a bigger turbo? Or is that a waste of money. I dont want to get a bigger turbo and then need to upgrade several other components to make it work well. Advice please!!!

For a bigger turbo...then you'd have to upgrade everything else. Throw the 5931 on it...and call it a day.

Like he said. . With the tires you run, you don't have enough traction anyway

ordered up the 5931 this morning  :rock:  sent a message to Eric about my TT chip to see if it would need to be redone because of this turbo change or if I could just tune with chip I have installed?
 
Will I see much, if any, performance gain with this turbo??

If your turbo was a stock one...then it should pull quite a bit better on top end

You have version 5.6 alky chip...which doesn't have aggressive mode. His 5.7 alky chip does...do some reading up on it. From what I've seen...you'll need more 3rd gear fuel.

Stands to reason. More air in requires more fuel to put with it. Good call on the updated chip.

I noticed you went a notch up from the 44/49 turbos...looks to be closer to the old 60 series.  Wondering if you have enuf converter?

Told the guy at full throttle it wasnt stock, didnt know exactly what I had but it must be very close to stock, and he thought this one would work well?
 
Can you tell me what to expect if its a good combination or more importantly what to expect if it isnt? Probably a stupid question but I dont know what I have and the shop that did it ( tranny rebuild with new coverter) didnt give me any numbers for it. I'm assuming it has something to do with a stall RPM but I'm clueless about how to determine that???
