I'm pretty sure you can bolt a gtir t28 on the Bluebird manifold, but then you have to grind some material off the block so it’s a better option to fit it to a gtir manifold.
250awkw is going to be a pretty hard figure to get for a hnu13 considering gearbox weaknesses and driveline loss, none of the turbos you have listed will make 250awkw, although you should be able to make over 200awkw with the gtir t28 or the gt28rs.
Here’s my 2c as you are welcoming opinions.
Aim for a lower number maybe between 180-200awkw, it will be easier and depending how you treat the car you should get away with the standard gear set for a while, don’t get a too heavy clutch its better to have a clutch that slips a bit this will give the gearbox a bit of a break. (If your car is auto then I don’t think you have much chance getting much more power out of it without destroying it)
180-200awkw should be great for track work using a fairly small responsive turbo, it should keep you happy. If you want your car to have more power than this and intend it for drag strip use you should ether go the cheaper route of buying a different car, but if you must have a hnu13 drag car id suggest get yourself a ppg gear set and talk to a gearbox specialist about strengthening the casing.
If as I said you want to make a drag car its not only a strong gearbox you will need, for 250awkw you would be best to have the engine built with forged internals and you will need a fairly decent sized turbo (maybe a gt3540 with a .64 exh housing) and with a turbo that size you can forget about mounting it on a bluebird or gtir manifold you will need a custom manifold made up locally or you can buy something from the USA like this

Honestly if you had a 250awkw hnu13 you would proberly drive it a lot less than you would a nice 200awkw hnu13, trust me my friend has a 260rwkw silvia and he drives it a lot less now that it is 260rwkw than he did when it was only 200rwkw. When cars get to that sort of power level you don’t really want to drive them as much because how dam expensive they are to run and were not just talking fuel you have to consider brakes, tyres and clutches as well. I mean my friend with the 260rwkw Silvia spends $2000 on a set of 4 tyres alone and with that sort of power and that exy tyres he still has traction problems in dry conditions, I know awd would minimise this but still you will be using tyres very quickly.
But if you have the money to spend go for it because 250awkw in a hnu13 would be sweet.
Personally I'm aiming for 170-190awkw in my hnu13 I'm hoping to achieve this with the following:
gt28rs turbo charger on gtir manifold
3" exhaust
550cc injectors
ecu (unsure what type yet, cheep as possible hopefully)
boost controller
possibly cams if I don’t break 180awkw with this setup
(an the mods I already have pod filter, larger FMIC, high-flow fuel pump)
lwsjss's setup is also a very impressive setup using the larger gt2871r
I hope I have shed some light on the subject from my experiences and research I have done for my car.
Anyway speaking from one HNU13 owner to another that’s my 2c.
PS. $150 for a gtir turbo thats in good condition, for that price its worth it even if you only use it for a few months before upgrading.
