I am redoing the engine due to broken crank. It already has t66 turbo, under drive crank pulley, kb headers, wastegate to work with headers, 3 inch downpipe and full 3 inch exhaust, kb air to air, kb intercooler piping, kb 4 inch intake, kb fpr, 40lb injectors, boshe 044 ext fuel pump, stock ported heads, eagle rods, trw pistons L2441, sfi flexplate, accel dfi gen 6 calmap, 3 bar map. I am not sure on cam specs, have to have it cam doctored. I'm also not sure on converter #20506r3. Prev owner had no clue what was done to truck, I am finding out the mods as I tear into the truck. What do you suggest?

Things I would like to do:
alky kit.
scat crank
have tuned with someone who knows dfi gen 6 (any suggestions?)
60lb injectors
converter (if mine is stock)
new rings (any suggestions?)
oil pump (any suggestions?)
double roller timing chain
what cam would be best for my combo
Please tell me what I should change or what is a better combo for my mods.
Thank you for your help. Kevin

I know that you mentioned you want to run low 12's. I would guess your cam is a KB cam since its seems like a previous owner ordered the KB catalog. The T66 might be a bit more of turbo for a set of stock heads, I guess it depends on how heavily ported they are. You defiantely have the parts to achieve you goal.

Oil pump, you only need a standard volume pump. However don't use the Melling M55 (unless you want to pull the motor in a few thousand miles), using a Melling Select Oil Pump.

I don't know what to tell you about the ECM, I don't think those have a wide band O2 and are is an older ECM, I am not if they have much support. If it was me I would looking into swap back the stock one (not sure how hard that would be).

My other suggestions while the motor is out

-Swap motor mount (you need frame adapters available from vendors), you can use poly mounts with KB Headers. reuse the stock heat shields, if those are missing MikeRenz sells them (I also have a spare set).

-Check the transmission oil lines, they someitme rubbed through be the oil pan metal bracket. (A lot easier to replace with motor out.)

-Check the remote oil cooler/filter lines, if they are leaking replace them,

Re: Need help with my ty engine build, suggestions please!

the main thing you will need is a user friendly stand alone tuneing system like FAST ir a big stuff. I have almost your exact setup but with 75lbs inj, a FAST system, 2.02 valved ported heads and alkyinjection. i would also sugest that you get a double pumper fuel system from RPM,i had an in tank 255lph and an external bosche pump and it wasnt enough once i started cranking up the boost. An exhaust temp gauge will also be recomended seing as though it will tell you if your detonation or not. i made 450 hp to the ground at 25psi. i havent taken it to the track but judging by racing cars that have it is good for an easy 11 somthing @ 25psi and 12 somthing @14psi. i am in the process of re doing my engin this winter and from what ive learned from anderson or RPM a nitrited treated crank is a must once you get clost to 450 500hp. i will be runinng the same setup but with je pistons, a nitrited crank and this time a zextronix wideband with a sender wire that can actuate a seleniod. it can be set to go off at a desired air fuel mixture so if you get too lean the selenoid can shut off your processor or spark or even initiate a diffrent fuel map if your system suports that. Addded reliability.
