88 t-bird stock turbo?
 

im trying to remember what the stock turbo is on my turbo coupe it's an 88 so i know it's got the smaller ihi turbo but i for the life of me can't remember which one it is
i am thinking of going with somthing like a t28
but honostly until i can figure out what size the ihi is i don't know if a t28 would even be beneficial
also on a 2.3l how would a t28 spool?
im currently making 15psi at about 3200-3500rpm (tho i hear if i open up the intake and exhaust some it'll me making full boost arround 2000-2500rpm, which would be nice. the boost hitting that late but so fast and hard when i starts to spool is kinda dangerous, i mean in the wet if im just cruising along and the revs hit 3000rpm under say 15-25% throttle it makes boost and will take off unpredictably and if im in any of the first 3 gears when this happens i'll cock the car sideways with no warning)

stop ------- posting and research a little bit i know the answer is on here some where.
1. its a .48 compressor
2. why go with t28 when its already a t3
3. all t28s spool differently
4. learn how to drive

why don't you pay attention?
it's an ihi turbo
they stopped putting the t3's on in 1987

All Mustang SVO’s, Merkurs and ’83-’86 T-birds used a Garrett (Air Research) T3 based turbo. Vehicles equipped with an Auto tranny used a turbo with a .48 A/R (‘small’) exhaust scroll housing for better low end boost. Manual tranny cars had a .63 A/R (‘large’) housing which breathed freer and had a better top end. A/R stands for Area Ratio it is the area of the scroll housing divided by the radius of the housing from the center of the scroll to the shaft center line. The larger the A/R the more efficiently the turbo will make boost compared to one with a smaller A/R. ’87-’88 T-birds used a turbo built by Borg Warner’s IHI division and are referred to as IHI’s. The IHI unit is physically smaller than the Garrett and is not capable of putting out the same max. boost. It does however spool quickly though and could be considered a good choice for a moderate performance truck. ’83-’84 turbos were oil cooled only and tended to lead a short life. All other turbos were oil and water cooled and holds up better


but it doesnt say what ihi is

thanks i appriciate it
