I have some stuff that my car does that im to unsure about, i just wanted to see if it was normal, my mods; hks ti carbon catback, godspeed downpipe, kartboy ss and utec is going in soon. 05 sti with 11,566 miles

1st: when i turn on my car :sometimes: it will emit a clear white smoke and when i smell it it smells like gas, pretty badly, and i can see through my exhaust its all wet with gas...so im thnking running rich, i lose 0 oil.

2nd: when im flooring i am around 3000rpms in 1st gear i mash the gas, and it stalls a little like maybe half a second then the rpms fly, but im very unsure about why it takes long.

3rd:shifting 1st to 2nd hard i hear a thump noise, i know its the diff, but, is it bad?

Finally: when i start my car ill hear a odd whining noise and ill see the bosst gauge going from .-70 to .-69 but as it warms up it stops.

Thank you for you assistance, please help sleep better.

 

well i can say for the 2nd question is that your probably experiencing lag

 

Humm ive heard that the sti doesnt really have any turbo lag but it is still turbo..

 

the lag is not bad but it's still there. everytime i hammer my sti it's not like it fully boosted right away.

 

you need a tune to help with the Open Loop/Closed Loop delay and lag.

you will need STi Gruppe N stiff motor and tranny mounts in first regarding the shift "thump", before you go to stiffer diff bushings/diff bolts, or subframe stiffer mounts/lock bolts.

oh, see you're getting UTEC, good luck!

 

i have utec but its not installed

 

I didn't think the STi had th e OL/CL problem like the regular WRX.

 

I have an '04 STi, and the delay is still present.

all 04 and 05 ecu's have that delay, WRX or STi
