You seem to know a lot about this kind of stuff - thanks for always answering my questions
Theoretically, no, but anyone who is going with this twin turbo setup isn't going to be running such a low boost IMO, the setup would be overkill for that. You can get 5-6psi out of a fairly small single turbo.

Agreed. But would it be better to get an already built crate motor that can handle that or rebuild the stock one? Unless you're doing it yourself crate might be the way to go? Just guessing I have no experience with a total rebuild.

Upgrading the current engine as was done here is a better choice IMO. You are only changing what is really needed and you know exactly what you are getting and how it is spec'd. Cheaper also (relatively speaking, it's still going to cost you). Crate engines can be expensive! An OEM crate LS7 (427c.i. that is in the c6 Z06) can go for $14,000! Standard LSx engines half that. A crate 426 Hemi can run near $15,000+ I think. Considering what would be needed here you'll be on the higher end and it still may not have what you need in certain areas, or may have things you don't need.

Re: Twin Turbo 2013 srt8 in progress

OK let's talk pricing, This kit built on your jeep turnkey with trinity and dynotuned
With upgraded fuel injectors with precision 5862 journal bearing turbos will cost you
$15,500. Coatings additional $1200.
That will get you as much as stock trans can handle.

At that point you are setup for whatever power level up to 1100 wheel HP.
As far as boost per pound turbos make more at same boost level.
Superchargers require the engine to spin it to create boost. This steals HP.

Now if you are just looking for 100 HP and that's it I would tell you to supercharge
all day long.

I'm here to show you what options are available.

As far as upgrades go, they sell a nice set of forged pistons that are drop in
without major cost or engine work. That would add about 4k to the build and
handlle 750-800 HP all day long.

Add a trans (2012-13) for additional 4800 installed.
Add another 1k in fuel delivery needs and you have a sweet
750 who pump gas DD.
My math puts that at a total of $24,300 out the door!!

Now let's do cost per HP.
Let's say stock jeep will make 400 wheel.
For 750 wheel your cost is $69.42 per HP.

If you have any questions you can calk or text me anytime.

Re: Twin Turbo 2013 srt8 in progress

Is the kit available without installation? I'm one of those people that takes pride in building my own vehicle and installing stuff myself instead of paying another mechanic to do it.

I pretty much have it broken down as so:
Forged long block $7-8k plus labor/tune (though a fully built one from arrington with all the special coatings, roller rockers, ported/polished heads, turbo cam, etc priced out at $15-17k )
Trans w/ converter: $6k (to be installed with transfer case and driveshafts)
Transfer case: $3k (installed with trans and driveshafts)
Driveshafts: $2k (installed with trans/transfer case)
Axles: $1k (no solution for front that I'm aware of) plus install

^above *should* have me all set for FI

Twin turbos: $15k w/tune and install
Fuel system: $3k (??)

total: $40k
