Yes the gtir manifold sits closer to the alternator, its more of a tuned length that the origional,but you have to look at other things as well like the zorst doesnt quite line up, the oil return from the turbo to the block doesnt line up properly, you will have to put braided lines for the turbo cos they dont line up, you can put a t28 on a standard manifold you have to mod the front a bit as they are a bit different for the intake pipe, 200awkw not a snow balls chance prob 150 if it a good one, you can run it at 15 psi but it does not make anymore power than what it does at 11psi just looks good on the boost guage and wears the turbo out faster, mircrotech i would stick with nistune, injectors you could use 440cc from S15 they will be all you need, me micka8 luke budgie and kranzy are all running in the 200 or better catagory, we have all tried the "simple" upgrades but they dont yeild much power you have to go to a big turbo to get the power you want, gt2871, gt2876, tdo4 conversion, i run a a hypergear ATR28 G4 trim turbo all these turbos will make close to 270-300rwkw on a s13-15 but only just over 200 on our cars cos the "drivetrain" sucks a bit of power out, we have all been here for years we have all wasted lots of money doing it the other way to get where our cars are now, you can take my advice and save yourself money and heartache in the end or you can make you own decission to choose your path to power, either way we will be here to help you.
