Life after a T-28 Turbo....
Okie so you have a t-28 turbo from RRM....you love it off but eventually the day comes where you need to upgrade, either for more boost or more power.
What turbos are available and viable after the t-28? I heard you can go GT-28 next...is that true? What about bigger turbos? Will the fit the RRM Kit or will you need new piping.
Just trying to have a little foresight as I'm sure Boe and many other turbo Lancers will be asking this question soon. And I want to see what path I can take after the t-28 isn't satisfactory anymore.

Actually you should be on big 28 and instead of going for a different turbo just get yours up'd. Talk to Rob as there are many things you can do to the turbo to decrease spool time/lag and increase effiecency on the turbo you already have. Plus you're not even using the turbo to its full yet anyway. even at 9psi your still barely getting there. With bigger fuel pump/injectors you'll be able to go up to 16 where you'll see the turbo really used. It has some more but i'd stick with that as a max. You'll definately need to build the lower motor and get some ARP head/rod bolts for doing that though. Also the FMU will need to be upgraded as i believe it is only good for about 12psi. Talk with ROB and he'll give you some numbers if you serious. Besides building your motor you really are not far from being able to push the 300whp area. Just rememeber Trannies/drive shafts are not going to take that abuse for long. Stick to around 250whp/tq and you'll be good and fast as all hell. IF you think about it that is like 290hp/tq at the flyweel!!

The maintenance itself may not be so bad, but getting the car to run properly (read: tuned correctly) will be a royal ***** almost guaranteed. I wouldn't worry about maxing out the T28 so quickly though. It may not be that big, but the amounts of money and work it'll take to reach its peak flow rate will be major deterrents (sp?)
Oh, and if you go standalone...gooooood luck. You're gonna need it. Another thing that'll be absolutely key will be a wideband O2 sensor. AEM just came out with their UEGO which should be just about the best option. I should be purchasing one shortly myself so I'll let you know.

RRM has turbo reflashes to go with their kits now. It'll be fine, Stew. The turbo just isn't going to produce a lot of boost before you max it out. The chances of you pushing your t25 to its limits before grenading your stock internals are slim though. You may come into heat soak problems running more than 6psi non-intercooled though. (I don't remember whether you were planning on getting an IC or not).

I'd pay to see the response to that. 
Best bet (since you're sticking with the stock ECU) would be to run recirc. You're not going to get much of "poosh", but at least your car won't run funny and stall.
