What Turbo?, built 3s Options

[celicaracer18]

Whats up guys, its been a while. i've been so freaking busy with working and going to school in Alabama and going back to meridian MS every week to work on the car and just haven't had time

and yes the final date has changed i wil not be getting my car back this year

i will be taking the car to XAT on dec 10. over a month later than originally scheduled because of complications with getting the motor there.

i'm no longer getting the 3rd gen MR2 3s, i'm getting a 4th gen caldina motor now.


it will be built and i was getting the turbonetics t3/t04e 60-1 ball bearing turbo. but i'm not sure if i still am or not.i think i am going to get that or the turbonetics t04e 60-1 ball bearing turbo. so if you guys that know alot could give me some advise. or some other turbo suggestions. thanks


by the way just so you know the motor will have .20 over pistons, knife edged crank, balanced and blue printed block, slight port job, and all nrw internals, ferrea valve train with HKS cams, custome intake and exhaust manifols and all custom piping, to name all the main parts that affect the motors power out put

I second the turbo makes 588whp on a 2jz mid-mild tune. and he said he was going to upgrade all internals.

how much HP made on that motor is totally relative because of the different mods, the engine volume difference and MANY other factors.......so that pretty much has no value to his application.......


but Dustin like i said online last night....(in agreeing with Jay) the GT35/40 series turbos are going to be the closest in terms of efficiency of the turbo, size of your motor, RPM range and boost levels

for some real information


using this turbo, at that specific trim.....bored out to a 2.1L motor

the BOTTOM horizontal line is 10psi
the next one up is 15psi
the next one up is 20psi
the TOP on is 30psi

the farthest left TICK MARKS on each horizontal line is your motor at 2000rpm
the MIDDLE TICK MARKS on the horizontal is your motor at 5000rpm
the RIGHT TICK MARKS on the horizontal is your motor at 8000rpm

so you can conclude this turbo will SLIGHTLY big for your motor but its a good starting point for your referances.....

the details of what i did
~PR~
(14.7 + 10) / 14.7 = 1.68 bar
(14.7 + 15) / 14.7 = 2.02 bar
(14.7 + 20) / 14.7 = 2.36 bar

2.1 liters
2000/5000/8000 RPM
90% volumetric efficiency
PR

~air flow in CFM~
(2.1 x 2000 x 90 x 1.68) / 5660 = 112.19 CFM

~air flow converted to pounds per min~
112.19 / 14.27 = 7.86 (lb/min)

then graphed approprietly.....
