hi all ,
nice article ,and thanks for the help ...
I have problem and I hope that you could help me with it .
three weeks ago I finished my project 2001 Nissan premier :
http://www.sr20forum.com/showthread....74#post1112674
the list of parts I have :
S3 cams from JWT.
I ported the head and install bigger valves .
I ported the intake manifold as much as I could .
255 fuel pump .
720 injectors .
JWT.ECU .
Ford mass air flow sensor .
8.5 compression pistons .
H rods .
I had to spend a lot of money and effort and research because the vehicle was with an SR20DE and not SR20DET. so it's non turbo ...
the numbers I've got so for :
- 260 on 11psi
- 295 on 15psi
- 350 on 19psi
- 382 on 24psi
The problem I'm having is a really annoying idle. I started Car in the morning and I have my 1300 RPM after warming up it goes down to about 1000 or 900 .if I got it slowly with no boost I'm fine .but if I slam it couple times than the problems start coming . I boast it up in third gear for example and then put it in neutral the RPM would come down from let's say 7000 all the way down to 200 black smoke will start coming out and RPM start going up to 1000 and down to 200 if I'm lucky it will stabilize on 1300 or 1400 ,or it will die and I have to start the engine again .
on coosting or light throttle the engine would jerk .
I've done a lot of some research , I have changed the idle control motor , made idle relearn . adjusted timing . and checks for vacuum leaks .
I help you can help me , and I am willing to answer any questions that might might help me .
thanks a million
