So qjuestion for you..this is a stick car? If so what clutch have you found that can hold that power output? Or is it totally custom clutch?
And to 5172 think it is. The average guy maybe wants 500rwhp from his turbo setup. The average guy is on a stock engine. The average guy don't want to spend the extra that it would cost to go up to GT35Rs.
That said there are people that always want more hp even if that hp level is beyond stupid ,especially for the street and we have a few track cars with stupid hp that manage to smoke the et streets all the way down the track. They don't et that great but they do impress the crowds and get some good miles per hour.Scary rides too all over the track a lot of the time.
The average hotrodder is probably pretty happy to hit 10s in a car that can be daily driven like JMs low 10 second aps standard turbo kit at 10psi. On my track you need special liscence to go 9s.Full cage and stuff. 9s is plain crazy stupid fast. Litre bike fast.
And I jumped on my kit cause it cost mid 5k range. At 8 or 10,000 with bunch of upgrades might not have got it.
Its fine for APS to offer some upgrade options. But they should keep their base kit affordable.You are already getting a twin turbo kit with intercooler for a reasonable price. And think the latest runs with JMs car have put to rest the talk about too small turbos for 346,370 ,402 or 408s. 427 well maybe they will be a bit small there but again if the car can hit 9s maybe on a 427 at 10psi whats wrong with that. Maybe someone will try the small snails on a 427 build this season.
Should be interesting.
Why does a person have to turn high rpm or run high boost if they can get 9s without doing that stuff. Lower boost has some advantages. Bigger dsiplacement has some advantages especially off boost.

GT35R versus 20g pros and cons
GT35R cons
More expensive
don't think can be rebuilt usually pretty reliable
bigger not sure if going to cause any ground clearance or other clearance problems
Not everyone may need the power these can put out.
Pros
Can put out more power than 20gs
Hold boost better between shifts than non bb turbos which is more important in manual cars, autos tend to keep the turbos spooled up.
Faster spool up than non bb turbos..this one is a bit debatable.
And yes JMs car does seem to have a bit slow spool up. Not sure why.intake manifold,cam choice,heads,tuning,it being an auto..not sure .Have seen several dynos of faster spool with the 20gs from aps and other aps cars.Including some 346 not just 402s.Would think upper hp limit is 1200 to 1300 rwhp.
Pros and Cons of 20gs.
20g well cheaper than GT35R not sure by how much exactly depends on what APS is paying for both turbos.
Rebuildable,very common turbo. Track record of reliabilty and durabilty.
Compact size.
Still capable of putting a near two ton car into the 9s at 140 plus mph.
Upper hp limit likely around 900rwhp.
And just a side note but in the dsm world where we use both 20gs and gt35rs the gt35s still seem to spool a fair bit later than a 20g at least on the 2.0 and 2.4 engines. But on single engine cars the 20g gives around 500 max engine hp and the GT35R about 700 to 750. Its main advtanges are the way it holds the boost on manual cars and it is still a pretty quick spooler for how big it is. I run a slightly smaller version on my 97 talon and likley will run a GT35 or possibly T67 on my 91 auto talon race car. Race cars don't need to spool fast just rev them up and let them go. So a bunch more lag is not really a bit deal especially in an auto car.Keeps the boost up good between shifts even with non BB turbo.
Anyway it can't hurt for APS to offer GT35R upgrade and they would be wicked on 427s and 454s for sure.I still am very curious to see how the small snails will still perform on a 427 engine. There is a big difference between theory and practice in the real world it seems.

I just ordered my kit..... don't ya' hate it when something new comes out right then? 
Actually, the power the standard F-Body kit will make will be plenty for me. I am sure watching with interest about this kit though.
