I basicly openened this thread for those who are intrested in turbo specifications for specific ar.'s and Flow testings. Before i compleetly open this thead i would like to state that i am also intrested in one or more of th ese turbos to be equiped on my 1809cc ca18det, so any info you may have or words you wish to express on what you think might be the most applicable choice of turbo would be muchly appreciated.

This Could become a sticky if more of the forums memebers came in and sicussed their set ups and turbine knawlege.

ok First i'll start off on the lower Turbos. the T2. serries

-t25
Origin s13 Ca18det
ar. 48 Turbine
ar. ? Compressor

-t25g
Origin s13 sr20det
ar. 64 Turbine
ar. 80 Compressor
Flow Capacity of 230hp

-gt25r
garrett turbine
ar. 64 Turbine
ar. 80 Compressor
Flow Capacity of 250hp

-gt2510
HKS line Turbine
TURBINE:
-Wheel- 62 Trim - 53.0 Major / 41.7 Exducer
-Housing- GT25 inlet / Internal GT25 oulet - 0.64 A/R

COMPRESSOR:
-Wheel- 63 Trim - 47.7 Inducer / 60.1 Major
-Housing- 60 Inlet / 50 Outlet - 0.60 A/R
Flow Capacity of 300hp

-t28g
Origin GTiR Pulsar AWD
ar . ? Turbine
ar. ? Compressor
Flow Capacity of 300+hp

-gt28r
Origin S15 sr20det
ar. 64 Turbine
ar. 60 Compressor
Flow Capacity of 310hp

For those of you who are Running any of the former gt25 serries turbo's what is normal boost spool up and when does pressure drop. Beacsue i'm new to turbo's i do not fully understand these compressor and turbin maps.

here is the set up i had in mind for my vehicle, keep in mind that high HP is not my goal. just quick spool up and a good responsive engine.

Plan 300 wheel dyno/ 270 wheel street
Use grip/drift/touge quick spooling turbo w/pressure drop after 7k
Barnett PND 1089cc Possibly Slight bore to 1854cc
Complete bottom end balance
cp pistons
crower rods
metal Head gastket
3angle valve jobb
full exhaust port
ka24e throttle body
z32 AFM
550cc Injectors
HKS 264 cams
FMIC, full turbo back exhaust
Eprom or FLASH ecu w/piggy back safc
walbro 255 lph fuel pump
gt2510 HKS turbine

again this post is open to those who want to share their set ups and or ideas with turbine knawlege.
