Well i have words for this
all naughty.. but also super pissed at myself. Never once considered the $%^&ing injectors to be a major concern.. but now that i have done some internetz .. big $$ mistake..At bosh's 1 billion cycle rating *in a perfect lab* it makes tons of sense that it would happen eventually and i should have replaced the freaking pos bastards a year ago.
Here in the real word with crappy gas, water, and real engine heat and grit i bet that 1 billion cycle rating drops quite a bit. Add in we race the damn things and poor heat shielding on bank-1 and we can likely take a little more off the remaining duty cycles. Dirty napkin math says with 16 hours a week driving, and 20% reduction on the rated duty cycles with a assumed 1800-2000 rpm average my injectors probably should have been preventatively replaced about a year ago 'to be safe' under a extreme duty cycle regime. whoops..
#$%^ ..... just ....... $$%% .... never even looked at them once in the last 35k *hard* driving miles.
7k$ lesson right there.
So the update is this. Wife said "BS that things sitting idle while we make payments on it, and NO you cant have a SRT/hellcat.." so against my (mostly)-BITTER better judgment were going to rebuild it. we will try for a 40-50k long block.. but failing that we're going remanned.
ugh... ugh ugh ugh. then i have to decide to leave it stock or rod it back out.

Not only did she step in she opted for a new remanned block out of washington with a 3 year / 100k .. So i guess were doing that? I am shocked honestly. I was ready to let it all go.. but i think shes too used to having two drivable cars. She still shot down getting a model-3p though
So were about 3 weeks out .. to be continued.
The block and heads and all will be new, I have also ordered new water pump, and rubber bits and hot pipes.
so dumb question .. I'm REALLY happy with the Brad-tune i had. And the new block and setup will be 'newer' and prone to LESS pre-igniton and support better timing with less carbon in the cylinders. do i REALLY need to rebuild my tune from scratch? If the turbo pressure delta is 'right' (requested and actual), spark is good and not causing knock, and ltft and stft show clean steady numbers would it be safe?
You verify the reman does not have new water pump? Just seems that water pump is part of the timing chain setup, so I would think for it to be a longblock with timing gear the pump would be remanned also? I could be wrong, but I would definitely check that before throwing $ at a new pump. Make sure they replace all the injectors and do not just throw the working old ones back in when they put it all together. Some dealers will not do that by default and then you eat another motor in 5k miles...TopherSho said:FoMoCoSHO said:

As for Tune, run it bone stock for a while, couple thousand miles maybe? After that you will want to talk to Brad, new long block and injectors you need to retune it. It really is a different motor once done. Honestly it is not that hard to do over the course of a week while driving to work. I would log my car on the way to and from work (cold temps in morning, warmer in afternoon) and send him the file soon as I got home. I usually had new tune before I left for work the next day, rinse repeat. If no tune the next morning I just would not romp on the car until I heard something back from him about how safe it was.
