Ball bearing turbos
Anyone with experiences on the GT35/40 turbo?? What kind of spool up are we talking about?
My next mod is the turbos, trying to decide on which ones to go with. The M2 twins in none seq mode is said to spool up around 2500 rpm and puts ~450 to the wheels. I will be using the AEM ecu to do the controls.
The ultimate goal here is to increase power but not lose streetability. Any comments, suggestions or recommendations??

You need to go single and run a T04S and you should get that with ease. And should have no problems.

Does anyone have any data on the response times between the different turbos?? If so, it should be compiled into a chart for reference. (there was a comparison chart done for wheels, quite informative)
It should include Manufacturer, Model, Max output, Response etc.
Maybe we can poll for everyone who has a particular type of turbo for input. So how about it guys??

If you want the car "streetable", stick with the M2 twins or a smaller single like T04 or the Apexi Rx-6 turbo. Talk to MaxCooper, he has the Apexi turbo. It spools pretty fast for a single and you can make up to about 400 rwhp. Talk to Artguy about the M2 twins. Supposedly they are built for 18 psi or so. That would definitely be close to 400 rwhp. And they spool by 2600 rpm.

M2's spool at 2800rpm's I beleive
Checkpoint Engineering is "supposedly" making parallel twins that will go over the 400hp barrier. The problem seems to be the shared manifold and Checkpoint is making it seperate. I'm not sure if I worded that might but you get the idea. I was looking at the GT35/40 Garet single BB and that shoulbe be about 450hp, similar to the Apexi. Max said the Apexi are not rebuildable. I have no idea if the GT-35/40 is or not.
If you changed your gears to 4.3 then the M2's would be kicking in at 2500rpms, which is just about instantly. If it's your daily drive or most of the driving is city/highway then you would be extremely happy with them.
The problem is how long before you want "more" power. Well, you will allways want "more" power.
There is alot more money involed in the single turbo that just the turbo itself.

GT35/40 is a big topic here lately. If you look in the single turbo section you will find loads of info on them. Supposidly it is full boost by ~3500 and can push upwards of 700hp. Here is a chart to show you different turbine wheels:

BTW I meant that it will hit 15 psi by ~3500. That would be my normal driving boost and then up it at the track so I was just thinking about what I would do. Sorry for any confusion.
