ka24de-t choking question

[BTL_nissan]

ok I recently made a post reguarding some godspeed turbos on my fresh build, you all have changed my mind regaurding these garbage ass turbos so I manned up and called a shop.

Gave them my mods list

Block:
81.5 mm over bore with wiseco 9:1 cr pistons
eagle rods
arp head studs
clevite bearings

Head:
supertech valve train (stock valves)
and gasket matched the exhaust ports

and excessive intake manifold (knock off)

Ill be running a log t3 manifold with 2.5 inch ic piping and intercooler.
walbro 255 fuel pump and 550 cc yellow top side feed 05 subaru sti injectors

anyways talked to the shop and they recomended a precision 5454e turbo. (659 shipped to my house new) and claimed to be in boost around 2600 rpms (which sounds amazing) and 350hp around 15-17 psi. will the ka choke up top with this turbo?

heres the specs on the 5454

MFS (Machined From Solid) 54mm Inducer Compressor Wheel
"E" Compressor Cover with 3.0" Inlet & 2.0" Outlet
54mm Exducer Turbine Wheel
T3 .63 A/R Turbine Housing with 4-Bolt Discharge
360� Journal Bearing System


now my second option is a 5431e which Im still researching.
specs on 5431e

CEA (Competition Engineered Aerodynamics) 54mm inducer compressor wheel
• "E" compressor cover 3.0" inlet/2.0" outlet
• T31, 76 trim turbine wheel
• Turbine housing options:
- T3 .48 or .63 A/R with 4 bolt discharge


i really want a linear power band no on/off switch while in boost, Ive been driving myself nuts trying to teach myself flow charts etc etc

anyone have any personal experience with either of these turbos?
im shooting for the 5454 for the quick boost responce and will be ordering within the next day or 2

thanks for the input!!!
