i gotta 90 turbo 7 with intake and rb turbo back exhaust with 720 cc secondaries and a afc. my problem is when i let the car sit and idle for awhile it starts to throw out thick blue smoke or black, i just dont smell any oil or colant burning.. engine only has 10,000 km on it. i checked my plugs and had good amount of carbon on them and so did my tailpipe. once i changed the plugs whole bunch of white smoke just came rushin out the exhaust and then cleared up.. i checked the coolant and everythings fine, oil is good also. is it running way to rich? or could it be my 02 sensor took a ****?

and one more thing is the 90 turbo rx7 flapper or hotwire on the afc the guy set it at pressure in6 out6 and what do i set it at?


thanks..

 

720cc secondaries are way too huge for just those mods. Im not turbo expert, but I say thats your probably running entirely too rich. If anyone else thinks so please back me up, cuz like I said I dont have much experience with the turbo2's.

 

i also have a 20b fuel pump. i drove the car hard today and was only down a quart of oil before i went for a good boot the oil was full....is that ok?

 

The 720 cc secondaries don't kick in untill after 3200 rpm he is talking about idle smoke. Check your oil metering pump. By the wayturning it off and leaving the car at idle for about 20 to 30 minutes before inspection can help you pass the emissions test mine did. I tried the idea and it worked, my uncle has an inspection station and it did not pass untill he suggested to run the car without the metering pump for 30 mins to clear the oil and it worked.
