The PTG1000 turbos are performing reliable and seem to be creating the fastest C63 and GT platform cars.
The Pure900 and Pure1000 are by far the two most popular stock housing upgrades.
Either way, you are fueling limited unless you put in new HPFP and/or meth injection. Neither is NEEDED, only if wanting to go beyond standard 93pump power levels.
Additional cooling isn’t a road block for 93oct pump power levels. If you are doing a bunch of track days in hot temps, maybe, but haven’t seen it being an issue yet.
My own personal thing is go the PTG1000 route, good and linear, adds tons of top end power vs ANY factory housing turbo. Small factory housing turbos need to run more boost and run hotter than a larger housing turbo like the PTG for similar results, but they still lack the top end.
Also, another problem I find with factory housing upgrades, is they are “punchy” and “torquey” because the power delivery is lower to mid in power band, and traction is hard enough in these cars.
If I were suggesting a route to go withOUT adding additional fueling, I’d go:
*Any intake / high flow air filters that are not pulling in hot under hood air
*PTG1000 turbos
*Red Star downpipes with your preference on heat shield/no heat shield, cats/no cats
*ECU tune
*TCU tune
These simple mods will probably net you over a second cut off your 60-130 times with no additional cooling/fuel.
Then hold on and have fun after 4,000rpms because things get nuts!
Agreed on the above post. The one thing that is missing from that list is a good tire. On 295 PS4S with PTG1000’s and catless DPs, I will spin at 80mph in 4th gear, sport handling mode (PFL car).
The recommendation I got from PTG on the TCU tune was unless I was going to implement meth, a TCU tune wasn’t a huge value add. 93oct and the 1000’s is okay for the stock TCU tune.

Thats what I like about ptg. They are not trying to sell you things you don't need. I asked about buying a tcu tune and said I don't need it. The car can't put power down first 3 gears anyway so what is the point.

the one of the potential benefits I see is a faster shift time.
Not a negative criticism….the dyno graph displayed shows exactly my point on the factory housing turbo upgrades. A huge “punchy” torque spike which makes the car a handful in certain acceleration situations, not fun when unexpected, as well as they still run out of breath up top.
The larger housing turbos will still be climbing in power delivery at redline, and not have that huge torque punch / spike low in RPM range of which can cause lots of wheel spin or you having to climb all over the steering wheel to keep it focused and not step out on you.
I would have expected a bigger turbo to have an even bigger and more sudden torque wave due to the extra time taken to spool up flatters the bottom end response......then it comes in hard. Fast response is why they fit smaller blowers in the first place and on the street that what I would prefer....high torque at low revs. On the dyno chart above even with stock housing torque has been sacrificed sub 3250 revs....exactly where a street car needs it.....I would not want to lose more at the bottom to gain unusable power at the top by going bigger on the turbo......Race car? (as in drag drip not race circuit where you still need the low punch!).....of course that a different set of requirements!

That is tuned that way for a reason. You will bend rods and blow your engine if you allow max torque sub 3000 rpms.there is huge stress on the pistons making 900ftbs at 2400 rpms
here is a car that you would love on the street but guess what? That thing blew up lol but man the low end must of felt nice.

that tuner seems to be known well for blowing up bmw's as well which they "specialize" in lol. I've heard rumors of a number lawsuits.
