Hi, I have to say that this has just kicked me when I felt I was invincible. I drove last weekend to Dallas, TX for my tuning session at T1 Motorsports, they did really great, I wanted to get a 50 shot of Nitrous by the way just to have something more, and they made the complete installation and tuning of my new all motor set up. My car is basically a b16 with stock stroke, just bored to 85mm with arias high compression pistons, RM 22x cams, Alaniz headwork, and all the extras (IM, TB, CAI, SMSP headers). It pulled 195.8 whp as you will see in the graph, on the al motor set up, and 223 with the nitrous shot.


Everything seemed to be great, I drove back to Monterrey, Mexico that day and when I got home I started to hear some tik tik noise at low rpms on the engine. I have to admit I did raced the car a little on the highway, obviously on the mexican one, where a fine is like 40 bucks even if you are going 120mph. Well it did hit the 140 mph BTW, and the oil temp was a little high but not anything to worry about, it was like 250 F.
After hearing this noise I did the oil change and the sound continued, checked the valves for any adjustment and the sound continued. And when we oppened the oil pan to take a look we saw the 3rd cylinder with some lines marked. We took of the head and then that piston and rod and here are the pictures of what we saw.

I would like some help to know what could have possibly caused this, I just don't want this to happen again. I have NOT used the nitrous ever since they tunned it, and that was just 2 runs on the dyno so please discard that.








Thanks.

 

looks like the piston to wall clearnces where built to tight for you setup. whats the head look like post a pic of that.

 

typical signs of to tight of a piston to wall clearance. i'm gonna go with that
