man, KD has so many sets of stock turbos layin around you would think they could get 2 compressor wheels together out of all of them, but hey atleast they are bein cool with the rebuild.

 

Crap! I have some RC 1300 installed on my new motor with ceramic seals!!

BTW, all of RC's injectors do comeback with a sheet that has the flow test on them. I think RC does this on all of their injectors...KD should have a record of this since they out sourced the porting no?

Can you confirm that RCengineering did this?

It still freaks me out on why specifically 1300 fail and not say 1200's? Is it purely the larger size?

 

Yeah, I have the flow test sheet at home with all my other "car stuff papers". They tested fine in all aspects, but the little bastard still killed my engine.

 

thats interesting that you have the "anit-detionation" device yet it popped adn nobody who replied even thought twice about it.

 

It may have been something else, not the injectors.

 

Call me crazy, but wouldn't a knock sensor have detected the onset of a lean condition as the 1300 didn't come online, and retarded fuel and ignition, to prevent detonation ??

J&S or AEM mind you, not the stock system

 

How hard would it be to add another port to each runner and use top feed injectors. I am sure the drivers in the computer could handle the extra load. With two sets of stockers 850 & 850 or 550 & 850 etc. That would solve the reliability and the use of hacked up over priced injectors. I just think the factory injectors, cleaned preform best, there designed to flow at a set rate for ever. End of rant.

 

my friend was telling me about this and he said not to get the 1300 because they are 850 that are just drilled out to 1300.

 

Yeah, apparently the 1200's aren't doing so hot either. Skip said that they've been testing them and they keep flooding out. Freaking injectors! Hopefully, all the bugs will be worked out by next week.

 

Anything from RC Engineering on this? Anyone call them to get their perspective? As I said earlier, I'm on my third year of daily driving and my 1300's are fine. I have one of the first sets they made. I know when our injectors go static, they stay open, not closed. Might be different from complete failure however.

This seems to be two motors through KD, both using the anti-det device that have blown due to injector failure. What are the odds?

 

hopefully, not misinformation. . . ::zing::

I found it hard to believe that a completely shut injector will cause an engine to blow. Actually, based on my experience, having a stuck injector will not even allow you to get the boost up. The car will fall on its face as soon as the 2nd injector comes in and run the same duty cycle as the primary. It's almost like a fuel cut in a way that it would just cut off the engine completely. The only way that an engine could possibly blow is if the spray pattern was wacked or the injector was partially open where it is still spraying enough fuel to keep the engine going, but not enough to cool the internals down (pre-detonation). Which if the car has an anti-detonation device, I would assume that it'll prevent it since it is catagorized as detonation?

just my .02

 

it's a tarp

 

I am running two Brand New OEM 850's bored out to 1300cc's. I think the problem comes in when using 11 year old injectors that have been sent off to RC to get bored out and cleaned.

 

Good point!!!!!


I drove my car with only one secondary coming on for 8 months. When ever the car would hit 3800RPM's and the secondaries where suppossed to come on, the car would die. I could'nt boost more than 6lbs. turns out one of my injector plugs was not in all the way and not making contact

Once I fixed the problem, the car ran awesome.

 

Just a question RedX7 when did KDR finish you motor ? I just find it strange they didnt give you a heads up your turbos looked like they were on the last leg.

I feel for you man,, I had two cores blown by shops and I am on my fourth set of stock twins .My advice is if you go used save the hassel and have them rebuilt , even if you get the " they boost well and dont smoke "line .

If I had to do it over , I would have let my FD sit for a year and just gone single when I had all the cash . All the lost time and ,money on stock twins

 

Correct me if I'm wrong, How would blowing your motor cause the turbo's to go bad. The apex seal does not go through the turbo's but through the downpipe.

 

They go through the turbines and usually tear them up before they get to the downpipe

 

that's stock turbo's

 

Pieces of the apex seal can take out the turbines, I'm surprised you've never seen or heard of that before....

 

or any other turbo. Normally it'll tear up the tips of the turbine blades but you can't usually see the damage until you pull the exhaust housing.

 

ah, it imploded ...sort of .Either way it sucks , keep the faith you will be back on the road again...soon

 

KD sure has a lot of injector failures...

 

You wouldn't have had these problems or the expense if you would have seen me.

 

Thanks Chris. Just rub a little more salt in the wound. The obliterated turbos weren't enough, huh?
