hey guys what's up, I haven't been on the site in awhile, but I have been building my nissan for about 3 years and as it comes time to start i have a couple quick questions.. first let me give you a quick rundown of what i'm dealing with... i am a Tech with Saturn for about 5 years so i'm not an idiot, I have a 90 240sx with red top lots of mods, the engine is back together and in the car, I wired everything, but there is one plug that i cannot find where it goes... It is the grey connector that runs in between the intake manifold at 3-4 cyl. There are two plugs, one I have plugged in (I'm not sure to what, i haven't looked at it in awhile) the other one is just hanging there, also I am looking for a spark plug one range colder than stock, stock is ngk bKR7ES11 correct? well apperantly there is no bkr8es, which would be a range colder...any insights? any help would be GREATLY appreciated, I have spent hundreds of hours ans 10's of tousands of dollars, and now that turn key time is coming near i'm amped to get everything right. as of right now i have: redtop, JWT ecu, greddy r spec, act 6 puck, jun flywheel, jwt c2 cams, springs,and retainers, jwt fuel rail and cam gears, rocker arem stoppers, t3/t4 tial 40mm wastegate, koyo radiator, tien ha, 72lbs injectors, cobra maf, 30 mm 300zx brakes, energy suspension hyperflex kit, (partially installed now, greddy headgasket, Nismo mounts and radiator cap, ported and polished head ,ANd about a million little things and probobly some big things that I am forgetting, I am shooting for low to mid 400's at the wheels and the car is stripped...i mean stripped lol anyway here is my rant thanks for listening and like I said any help would be Greatly appreciated. thanks guys

knock sensor?... i am sorry i thought this was a ka, but redtop would be an sr, do a search for FSM, they have it here always , hope it helps and you do have quite a setup... good luck
