Hey guys i have made the move to get me a 408 i have it now. its ready for boost i really want to make big power this year. im shooting for 900 plus to the tire with a 4l80. I bought me a turbo that was thought to be a gt47-85 but come to find out it was not. So now im on the search for a new turbo. what would you guys use to make this kinda power. as far as what heads/cam/intake ill be useing a set of l92/custom grind/and a vic jr. just looking for ideas here. oh and my turbo kit is set up for a large T6 turbo. i will drive this car a lot. so street driveing need to be taken into the thought as well thanks guys

GT55-91 if you have the extra $$$ laying around, if not then the S91 or the GT9197 which has the larger turbine wheel.

how about your FI-88x?

Great unit indeed, but for a 408, a 91mm is a better fit. Large cubic inch motors like compressor wheel sizes in that range.

It will be considerably laggier then the other mentioned units. For a street car they are not the best performers.

I like that 9197 garret you mentioned. It's a great turbo.

They are a great turbo indeed. We haven't had them out long, but the ones out there are making awesome power.

would a 101 be to much?

With a goal of only 900 rwhp, an expensive 88 wouldn't handle it? Not much room for improvement but wouldn't it be efficient at that level?

from what im being told on a motor as large as a 408 it will have to much back presser

Man Ricky, it is hard to stay up with you. Do you know how my old Camaro is doing? Bob

if i go way over 900 to the tune of 1300-1400...that would be fine

whats wrong with the turbo you have now? and i think an 88 would be fine i mean there are people going 4.80 in the 1/8 with them.

Once again those are thumper units. Lag will be an issue with those beasts.
