NX blew up!... need help

The NX · 09-06-2003, 12:41 PM

So i was at the 1/4 mile track yesterday running 13.3 at 107, and my buddy tells me, you can atleast get a 13.1, just turn up the boost a hair. So, regretfully, i turn the boost up, and when i take it down the track the boost hits as high as 17psi, when i shift into 3rd, BOOM, smoke started pouring out of my exhaust and my car was really choppy. I drive it to where i can park it, (its somewhat drivable, not for distance), pop the hood and there's oil all over my engine bay. It seems to me it came from the dipstick?? it all shot over the hood and stuff with extreme pressure. The engine still starts, but definaly not drivable, what do you think i did? and is it worth fixing? I have an idea of what happened, but i want to know what you all think.

Do you have a fuel ump in the car.

From the info that you have listed up top you need a new long block.

fuel ump? or fuel pump? what do you mean by that? what do you think is wrong with it?

I think he meant do you have an upgraded fuel pump in the car, because its not in your signature. No fuel pump and 17psi = BOOM. Sorry to hear that.

nope, stock fuel pump, with 370 inj... damn.. time for engine rebuild i guess.. but what happened? broken rod? hole in piston?

The NX · 09-06-2003, 03:06 PM

ive come to the conclusion i think i blew a piston, now what do i do? rebuild the bottom end or get a whole new long block?

i would get a new engine no telling what damage youve done to the block.....i just got replacemnt engine for my egg i missed 4th at 90 mph and hit second oops

if i rebuild i can get even lower compression pistons, but if i buy a new engine i may think about get an sr20ve and throwing the turbo on it

but thats a little pricey...

were you running a 3 bar of 4 bar fuel setup? Most liekly ran waaaay lean and detonation killed the fu*ker

spdracerUT · 09-07-2003, 11:10 PM

17psi and 370cc injectors=BOOM. 17psi and stock fuel pump=BOOM. You were pretty much screwed either way. 370cc at 4bar can't handle 17psi either; or at least I wouldn't! And the stock fuel pump is good for around 10psi. Past that and you're taking risks.

FastNX · 09-07-2003, 11:12 PM

And if you're running 17PSI on the stock T25, you were shortening its life too

The NX · 09-08-2003, 04:12 PM

i wasnt running it long, but it was long enough... it was on stock inj, and stock fuel pump. I'm running on s-afc tuned de ecu. I can tune it to as rich as teh injectors will go. But that wasnt enough, i heard the 13psi is the max the injectors and pump will take it. Oh well i guess i learn from my mistakes, expensive, but im learning the hard way
