• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Done with my rebuild!!



Ok so i pulled all my plugs and they all looked good but i decided to swap em out with a set of colder plugs i had and noise is gone :th_scratchhead: and no i didn't have any performance issues, when you have KR can you actually hear a difference. But i am gonna go with a full size and prolly smaller pulley... eventually
 
Just got back from the track, I ran a 14.7 and am kinda disappointed, I did however beat a 2000 gt mustang that was all gutted, a 07 sti, and a pos crx lol dont know what they all had done to em. But my noise is back now, should i just pull the motor tear it back down and check out the bottom end or just run it till it blows and get a new block?
 
Is there a certain way to set them i just tightened em down then torqued them to 11 pounds then did the 90 degree past that.
I dont really know that much about motors yet lol im learnin tho
Oh ya I dont have any check engine lights, just thought id mention
 


So...you had a tapping noise and went to the drag strip?

What are you exact mods? Any knock? Have a tune? Kinda hard to diagnose over the internet with little to no info there.
 
All my mods are listed in my first post but here they are again. cnc ported heads with 105# valve springs, machined lower intake manifold then i ported and polished it, and also machined and ported my supercharger, 3.4 pulley, and zzp pcm, no custom tune tho speed daddy headers with a 3in dp ubend delete, no cat but a o2 sim and a short autozone intake.
I dont really know how to tell if I have knock it usually runs really smooth.
And i went to the drag strip cuz the noise went away after i changed out all my plugs and my friends really wanted me to go and run my car i was really nervous, then i was like eh if it blows it blows lol not too smart I know

and yes theres 2 ways to set rockers, 1 with the car off and 1 with the car on. How ever with the way the motors sit in grand prix i think you will be forced to do it with the car off.
 


That is one of the vids i watched when i put my motor back together, im going to check it out tomorrow just to make sure though.
 
get a vid it will help greatly also for mods once you get this sorted out u shouldnt down size pully just do the cam or ic but run more timing also with your setup you should be running faster the 14.7 that seems sorta slow so u must have knock or somthing is wrong
 
Thats what I was sayin lol I have a friend who has hp tuners ill have to see if he can help me out with my tunage
 


+1 get a video up, and yeah get your buddy to scan it with you. No more track runs untill you figure out the knock otherwise you will be doing it all over again.

Is it more of a ticking noise? or a knock and is it fast paced or slow.
