I have a 2000 Civic Ex Turbo with greddy 15g turbo kit. intercooled at 0.3 - 0.4 bar maybe 5.5 psi?

heres the problems i have hopefuly ill find an answer for them.

1:When start car the rpm drops to 100..and almost stalls... than i have to give it a little gas to make ir idle normal?

2:Car doesnt spool up till 4500 rpm?? wtf the greddy kit suppose to spool arond 2500-3

3:butt load of check engine lights. mostly sensor.
-air tempeture sesor (i beleive i can fix)
-secondary o2 unpluged (i dont know wut to do with this) entend wires?
-Coolant temp sensor (mioght've gotten dmg while i was instaling)


my car is all stock except the Greddy Blue box FCU (which is suppose to make the car run a little lean)

Fuel pump ordered and is on the way.

also when i was putting the kit on the gasket the greddy sent me was the wrong one, so i didnt put gasket between the exhaust outlet manfold. (between turbo and downpipe) could it be a leak?

also one thing before i install the kit i forgot and accidnetly puit 87 gas from arco lol sorry.. i filled up with some octane booster..it was at half a tank. no ping or anything yet?

 

what exhaust do u have?

 

Are you sure that you wired everything correctly?

Can you post what wires you tapped in (ie, colors of the wires) on the wiring harness. It should be easy to tell if you miswired something.

i have a dc sport ss 2 1/4 catback exhaust, as for wiring im pretty sure its wired right. i used the diagram for the 99-00 civic ecu. off turbocivic.net oer something.

 

for the idling problem its your o2 sensor. thats what was wrong with mine. hook up the o2 sensor and car will run alot smoother and idle will be normal. im 100% positive its your o2 sensor.

 

how did you hook up your 02? it doesnt even reach..at all.. i was thinking extending the wires..but kinda skeptical bout cutting my o2 wires..and etc.. someone told me it will mess it up. my o2 is just plug onto botton of exhaust mainfold where header is.. and my original is all the way by the end of downpipe. what did you do?

 

solder and shrink wrap some extensions on there baby...or you can probably buy some factory extensions from an ex, i had looked at that once.

 

 

thanks guys heres the solutions i will try to fix thje problems

extend the 02 sensor to fix (idle and rough driving)
Air intake temp sensor (just shove it in hose betwen charge pipe and tb)
replace the coolant temp sensor (broken)

thanks guys for all the help
