I do all support mods pipe work, fuel system, inter cooler and increase the pressure in WG
my block is 2.0L with garrett t04z compressor a/r .70 and turbine a/r .83 with 1.8 bar using motec m400
cam bc in/ex 280
so i dont know why i got less of torque?

 

Big slow spooling turbo's always make less tq then HP, at least on our small engines.

Not bad power, what kinda fuel you using?

 

i'm in Thailand so i have using octane 95

 

Chart makes the car look very laggy but the scaling is off too.

 

BC 280s hurt spool as well.

 

now i'm on process to 2.2L
I plan to change the turbo for fast spoolin between 3000-3500
with 600whp 550 tq i think will change to power enterprise rx6r tcw-77 a/r22
or have any better choice

I had to4z on my supra i didnt know ppl like to use them on evo's

 

I dunno what spec Simon uses, but he uses the T04Z on his E3 race car:

If you watch videos of this car you'll see it is very responsive. 790 hp on E85.

 

I'm read the simon e3 spec a lot of hp with 2.2bar
I try to find video in youtube but not have.
I wanna know how they spool actually my car have similar mods with it but look like so slow in dyno -*-

 

T04Z is too big for a 2litre

GT35R is the way to go for a good compromise between response and top end power

 

gt35r all the way

 

ya bc 280's are garbage. I'd go with kelford 272's or BF 272's.

 

Here is a ND spec T04Z in action. Sick.

from many post not have much lovin in t04z.
from my graph if i change turbine housing a/r .81 to .61 it will better torque? and make graph pretty good? if dont look at my spool rpm.
