I have a 1991 da with sir2 jdm b16a head (pretty much stock) on a gsr freshly rebuilt block, bored to 81.50 ctr pistons, 315 supra injectors, chipped ecu. Arp head studs.not tuned.
Problem is the car is idling around 200-500 rpms. I mean it's all but knocking off. If you drive it whenever you shift it will knock off. You must keep fluttering the gas pedal. It is also blowing a decent amount of white smoke!
I used a 81.00mm head gasket. Im thinking maybe head gasket. Any help would be very appreciated.

 

help! lol!

 

hg is not your problem...my gsr is bored .5 over and i use the oem HG....and i dont get what you mean by knocking off? you mean cutting off? check your timing

 

yes the car is cutting off. im pretty sure its my timing. i've taken the belt off about 5 times and put it back on but its still outa time. im thinking i must be doing something wrong.

 

when did this happen? all of a sudden ? how long u been driving it? and i'm pretty sure u were supposed to get 81.5mm headgasket - i think honda makes that size....

 

well did you ever time your timing with a timing gun?

 

I had the same problem besides the smoke on my turbo y8 but it happened because my car was running so rich that it would actually flood and cut out.

 

which ecu are you running?
