I would do.k04 with Tt225 injectors. That will.give you the little bit.of power you want and the reliability as well

Ok so this is the deal, I have a 97 aeb 1.8t and need a new turbo soon. My main concern is being reliable as I drive about 500 miles per week with her Nd also trips up to the mountains to ski. I already have bilstein struts, tein springs, 3in test pipe, downpipe and 3in borla back, open cone filter and a couple other things. I'm running stock boost on my ko3 but need a new turbo here soon. I'm thinking ko4, franken, or a GT28 setup? Like I said I need reliable with just a little extra power to help pull me and a few other people up mountain passes 7000+ ft above sea level. Also getting the aeb tuned for my turbo choice is my next question, who does the best tuning and safest. I plan on keeping this car for a long time, she has a couple small nicks and such but I truly love my car but need her to breath a little better. Thank you.
Don't even bother with the K04. It's nearly the same price as a Frankenturbo and falls short on performance when compared to an FT. I personally would do a GTRS and call it a day if you aren't going with a full frame turbo setup. Along with all the supporting mods of course.
Franken would be the best bang for the buck IMO. If all you want is a slight improvement, that would probably be your best bet. GTRS would be a better performance choice but might end up costing you a little more.
