Wonder how long it takes for ARP to come out with head studs for these?

I've got a few of the factory 14mm bolts on my desk, the 6.6's have more bolts per head but they are 12mm. I think we'll be ok but we'll find out.

How much can you get out of the stock turbo before EGTs get unreasonable?
Stock turbo with a mild tune reaches 1,800+* in a hurry at 28psi. (this is an Isspro probe, not the factory probe that reads much lower)

With this twin setup, we see max of 1175* on the same exact tune at 50psi boost and 69psi drive pressure. I believe if the stock turbo wasn't as restrictive on the turbine side, drive pressure numbers would be even better, although that is also part of why it spools so quick.

Scott, What's your thoughts on the stock tranny holding the twins and tuning? Is it such a lower hp/torque rating than the big trucks that you aren't concerned with it, or does someone already have plans for a built tranny?

Honestly, I don't know yet. Mike L does I'm sure! I do have some Raybesto's clutches as well as pressure upgrades here, but that is something to address down the road.

I heard from Mike that you guys may be getting one or two :grin2:

I did, a bit of interest there.

On another note, we did get some tie rod sleeves on it today! I guess that means we have to do some 4wd launches.

I'd like this truck as a daily driver but not sure I want to go so far as twins. Any chance of a milder package with the stock turbo, delete, small power boost?

Sub'd! This is cool, but bad for me! The woman has been all wet about getting one of these. Says her WRX is going bye bye! I see what I'll be working on next. I said no go until there's deletes and tunes available, then we'll see. We both work at Chevy dealerships, so it's only a matter of time. Will be following this closely, keep up the progress, cuz this is neat!!!

I'm very excited to see this turn out. I just got mine after waiting 3 months and I can't find anything for it yet. Scott will you be producing any of your parts for sale?
I'm ready!
