Ok here is the scoop. I have a 98 gsr with drag 3 kit, 550rc injectors, hondata s200b with p28, tial wastgate@ 7psi, turbonotics t3/t4 turbo, fuel rail, fuel reg, ctr cam, cam gears, skunk2 intake manifold, jdm itr pistons, mugen thin head gasket, had it tuned by Lorance at DSR in San Jose and I am running 110 oct gas. one gal of 110 to every 3 gal of 91. The car ran a lot better after tuning. Then a week later I noticed a ticking noise while driving. I doesn't do it at idle or when you rev the car, only when your dive it and only at 1500 to 3000 before boost builds. Once I build boost I goes away. It is a pritty loud tick. Need help driving me nuts. I hope it is nothing serious. I took my plugs out and all 4 of them are white so I know the car is running lean. So maybe it is possible I might have fried something. It seems like the car still drives fine except the damb ticking. I know my compression is high that is why I am only running 7psi and using 110oct gas. I plan to drop down to 9:1 as soon as I get some money saved up.

 

Where is it coming from? If its from the bottome end I would stop driving it ASAP and check to see if you spun a rod bearing, If its coming from the top do a valve lash and see if that takes care of it......Best of luck to you
