ok heres specs..
91 s5 tII
90k on chasis, 2k on rebuilt s4 street ported motor, 10k on tranny, act 6 puck extreme clutch, new ecu (forgot brand), upgraded suspension, upgraded brakes, full exhaust, intake, 500+ cc injectors, huge fuel pump, upgraded radiator, all greddy guages to support (egt,a2f,boost,oil press)

tell me what you think? with all recipts and good workmanship, interior is in moderate condition, body is perfect with original paint. take a guess?

 

why did he put an s4 motor in??

 

also, doesn't the T2's come with 550cc stock injectors?

 

hmmm that is weird.

personally i'd try and get a S5 TII stock and hopefully one with a new engine in it already or low miles

 

Probably put the S4 motor in so he could take advantage of the mechanical OMP and lower compression.

 

Here in the Midwest- $6500-8000

In California and other rotary saturated areas- $5000

 

From what I have heard, the S4 turbo engines
seem to handle high horse power better than
the S5 motors. That was told to me by some guys
from Idaho who have raced both and blown both
motors, that was there results any way. I am not
sure if you can call that a true statement, but once
again that what I heard might have a little bearing
on the subject. Lates Matt22

 

I think that the s5's can hold more power because I remember reading about the dowell pins on the s4 turbo flexing at over 400hp or so. I think Ted has that info up on fc3s-pro.

if he is running a S5 engine harness and ecu it will put the ecu into limp mode without the electronic OMP hooked up. lower compressions means lower power. high compression rotors are the way to go

 

ya im still hoping my motor isnt froze up still i wanna see it run 9.4:1 rotors yes the s4 iron is weaker and dowel pins flex at higher horsepower from what i heard...
