2015 update with final e85 Dynojet, ramping boost from 16 psi to 21 psi (more in it but out of injector with ID1300; at 23 psi and 100% duty cycle over 850 whp):
Tuning has begun! 93 pump gas dyno below. It's nice not having to worry about my 5AT anymore, though I'm sure I'll miss it.
93 octane pump gas map with exhaust cut outs open (max pump gas power at 17 psi).
e85 maps with boost peaking at 24 psi and dropping to 20 psi at redline (max torque map).
Final e85 dyno curve with ramp up in boost from 17 psi to 25 psi at 6k rpms and up (to help with traction!):
3.5L non-sleeved Dynosty motor, Kelford 272 cams, twin GTX2867 turbos on a custom Dynosty built turbo kit using SFR 321 stainless headers. RPS Billet twin carbon clutch rated at 750 wtq with billet steel flywheel.
super nice trq curve. it crazy that GTR dynos are basically that curve but add 300 to every point.
Harder to recreate gtr traction. This is only 17 psi after all (and not a dynojet either). For a RWD car, I think I'll be able to live with this set up.
...sweet numbers raj....mind telling us the total time frame for Dynosty to complete your work? I'd like to get my trans installed one of these days.....
That thing looks like it just pulls forever! Great numbers!
Thanks guys. Let's see what she does on e85.

I can understand why you ask. I am not a patient person (my family tells me anyway), but the Dynosty crew have always been up front in regards to delays, causes, and options.
I looked back through my e-mails and it looks like they had a final work list with car in hand on Dec 17th. I was deliberating on what to do with the transmission on first arrival, but had already spec'd out the motor at that point, which they had begun in Nov. They helped me sell both motor and trans in Dec., starting my install in Jan with motor ready to go in. I went to visit Feb 27th and posted an update at that time. They had wiring, e-brake, CF driveshaft, and suspension work left to do (which I added on in Feb). I also added on some powdercoating after seeing some of the pretty parts in their shop for their other customers .
Cause of some delays: I supplied the e-brake handle and that caused several weeks delay as the cable length did not match up to where it should connect, which took an inordinate amount of time to figure out. It also turns out my e-brake had eaten through my (very expensive) stoptech top hats and the shoes needed to be replaced. Not sure how that happened as I never use the ebrake. I also decided to add an Exotic Air cup kit to the front suspension (Bilstein PSS10). They were not happy with the slap it on instructions I gave them from EA, as it decreases shock travel. They recommended machining a spacer and the top hat to allow full shock travel. All of this took time, and I added all this on in the last month.
You are interested in their transmission swap skills most likely at this point. They have experience with GM transmissions and 6MT swaps. For the 6MT swap, Dynosty gave me two options: they can weld in a new tunnel so it is identical to a 6MT (takes longer and more expensive as they remove the entire interior), or they can retrofit (what I chose since the work is all hidden anyway). I did want the all new 6MT harness (I was asked if I wanted to rewire my 5AT where needed) but I had water leak issues at the grommet and I wanted to keep it pristine this time around. Hal created two new firewall entry points for my custom audio and sensor wiring. No more water in my ECU connector, yeah!!!
Long story short, if you are up front about the parts that you will provide (I recommend none) and what they will supply, they can order in advance and keep it ready to go. It is less than a week's worth of time I think.
After all that said and done, Dynosty is very careful about hiring new employees. Most of my work was done by Hal and Eddie, with a lot of suspension guidance from Dustin. No unnamed tech like in other shops. Quality is top notch - really just well thought out. No hacks, always an OEM like solution. BUT... they are usually booked months out. They will tell you what the wait time is, so no point sending the car till they tell you to. Contact them ASAP if you're considering their services so you get into the queue!!
Nice to hear about the quality techs there at Dynosty...I have heard tooo many times about a. somebody's momma dying, b. somebody in the hospital, c. somebody got drunk and is hungover....etc...LOL
Yea, since they installed the th400, I assume they can do the th2004r as its the same bolt pattern.....just wondering how they manage the ECU with NON Nissan trans etc....will give them a call...
^ No personal excuses from the Dynosty crew! They are only human and some things are out of their control, including other vendors (Cosworth wouldn't ship, Drive Shaft Shop was moving, etc) and unexpected problems, but they are 100% professional, always.
Please don't bug Hal till my e85 tune gets done!!! Then the car comes back home! Then Triji's car is on deck, but go ahead and bug them then.

Thanks guys. I think Hal will take it up to 28 psi on e85.
According to my calculations the VE on this Dynosty motor is unreal compared to my last motor. The above 17 psi on a Dynojet would be over 700 whp? With this air hungry motor, I predict these small turbos will be max'd out at 25 psi. We shall see. I don't have sleeves so not sure I want to push it beyond what is reasonable for rwd traction anyway...
That is awesome power for pump gas, that low of boost on THAT dyno. I think those manifolds are really showing why a tubilar setup is superior to a cast/log style manifold. I understand that there are other factors, but I think that has a lot to do with it.
I assume this is a CP 8.5:1 CR motor? What is the a/r on those Tial turbine housing?
....and to add to the shop reputation, you will not find a better group of guys to deal with than those at Dynosty. They will go the extra mile without hesitation to make things right the first time.
Yep 8.5:1 CP pistons. A/R on tial turbines is 0.86.
Same turbo kit, different motor, different trans, (and of course different day,) max whp was 586 at 18 psi... agree, lots of factors. I have been very impressed with how well the tubular manifolds and GTX2867s work well together. I'm glad I didn't move up to the gtx3071. It would've been a different car.
i think the first gear drop in a 200 r4 trans is wayy to much 2.74 from the 3.794 in a 6mt or 3.540 in the 5at, the 3.06 from the 700r4 would be way better plus it has a stronger case. in either case you would need a tv cable attachment on the throttle and a fully built trans. the electronics are pretty simple im sure there are options out there somewhere. in all honesty though you would be better with a simple 4l60e, its the exact same transmission but fully controlled by electronics, slightly beefier internals from the factory, no tv cable and gm offers off the shelf controller solutions.

yes, I agree with your statements but my sources state that the 700 or 4l60e can't hold 800+whp? I have read no....some say the 700 is stronger OEM but can't be built as strong.... I do hate the TV cable on the 200 but like the light weight.....then again there's always the th400...just miss my OD.
