.63 A/R seems like it will have A LOT of back pressure. I would go with the .82 if it were mine honestly. What boost range are you looking to be in?

Forced performance HTA turbos are a good option too.

Depends on what you want but I agree. .63 will be a torque monster and will put 800whp down but .82 will pull better in the top end and can get you 1000whp if you want to push it. I'd get .82.

I'll be shooting for 1000+ rwp... True headers are being fabbed etc & these 5.5 600 motors aren't giant nor rev past 5700 rpm's. Motor doesn't rev high enough to take full advantage of .82 I'm told.. Torque will be in 1400 range.. Yes new inforced Clutch packs & Chrm-Olly drvshaft coming too

Your engine may not rev too high, but it has 6 liters of displacement. I installed a GT3076R .63 on a friends 1.8L Audi TT and he had 30+psi of boost by 3800rpm or so. Keep in mind that your engine is two 3.0L I-6's put together in comparison. You'll have full boost by 2000rpm but you'll also have a decent bottle neck in the upper rpms and I doubt you'll be able to get 1000whp on .63 a/r's. 82's will still give you full boost in the mid/upper 2000rpms ( which is fantastic imo ) and let it breath up high with no issues.

its a 5.5L but still the .63 A/R will hurt you if your trying to get to 1000hp for sure. My truck has a 75mm clipped to a 66mm with a 80-87 exhaust and a 1.0 A/R with 5'' down pipe and out a stack and i still see my drive pressure higher than boost with that big of a A/R. Usually boost is 63-75lbs and drive pressure will be in the 80's and i turn 4300 rpm max. If you looking for quick spool up and huge power those are things that don't go hand and hand unless you do your homework and talk to a turbo shop that really knows what they're doing. .63 is just way to tight to breathe like you want it to for your goals.

Again thnku very much!
I have not purchased injectors for MB V12tt motor from these compnies, but they know fuel injectors. It might be worth giving them a call to discuss.

I sent you the info i had in the PM. If you need the part numbers i have for the 725's and 1000's let me know. There's a local place here to that has pretty good prices.

You will need just the standard injectors with no adapters also so you might be able to get them a little cheaper. I paid $920 shipped for the 1000's and $700 for the 725's from a guy that bought them and Didnt use them.
What part number did you order?
