isnt the GT28 just a upgrade to teh compressor wheel of the T25 which is junk. It is decent turbo but not as good as a 16G and a 16G would cost about the same maybe even less. I would go with a Big 16G over that.

 

The MBC is fine. Like emonz said if you go with the 255 fuel pump you definetly need the fuel pressure regulator. You said you alerady have a high flow cat. So when you put the muffler on you will need them to make 3" piping because you cant have a 3" downpipe and then go back into stock piping. Your car will run liek crap. And also what is the opening in the cat. JW.

 

well the gt28 is small step above the stock t25 decent turbo if you dont wanna get into buying fuel system upgrades plus its bolt on for the 2g (no need for the jpipe). The 16g is even bigger and pushes out more hp for the money but it requires a little more time to install and get running right. Its basically all up to how much you wanna spend verses how much time you wanna invest.

 

lol sorry i f**ked up on that last post. I mean the gt28 is a decent turbo not the t25 which is sh*t!

 

My whole theory on it is get the parts little bit at a time stick them away in a closet until you have what you need for a certain section. I.E. you pick up the Fuel pump this week, 2 weeks later get the FPR, a week or month down the line get the injectors. Now you have all the fuel system install it. Now you get the muffler or the exhaust pipe. Then you get the turbo... Know what I mean?

 

IF I run my T28 @ 15 psi will I need a bigger fuel pump like a 190. I also have stock injectors. It I get 550's will my mpg be hurt any? Also will a front mount improve the mpg any?

 

going from a t25 to a t28 really isnt going to make all that bug of a difference so to answer, No you dont need the fuel pump for 15 psi. And i dont believe you would need injectors either

 

how hard is it to install, FPR, Fuel Pump, and new injectors if I have Haynes Manual?

 

they are not all that hard as long as you have tools an look up how to do it properly. Just take your time

 

my advice:
get the boost gauge right away, then get a walbro 190 pump. you dont need a 255

get the 16g, but not from that ebay site, its a chinese ripoff. if u do buy from ebay, look for a seller who specifically advertises: "mitsubishi heavy industry turbo, not chinese made copy". otherwise... well you are going to be payng for a chinese copy.

you dont need injectors yet, buy the turbo an run 15-16psi

read up on how to tune. etc before buying injectors

i get tired of people telling people to buy big injectors because 80% of the people dont realize you need to tune them an they arent ready for that yet. unless you pay a shop to do it for you that is.
