Good idea

 

I was just talking to ZZP about my build. I had the same idea as you with the LDK, but repalcing with wiseco pistons and K1 rods. I told them i was looking at least 500-550whp with either a 5858 or 6262. They said the block would be at its limit around that power, especially for a daily it would be not reliable. So, I only want to build this once. I'm going gen 3 girdled block, wiseco and K1, probably a 5858 and sending the 4.05 off to powell for a 4.45 upgrade if i can find gears in the next few months.

I think Cmiller also did a stock block with good pistons and rods with a 5857 but ended up cracking a sleeve due to the 32psi of boost, making somewhere in the mid 500whp. I would save up for a girdled or sleeved block.

 

i would think the 4.05 would handle the slower spool of a big turbo?

 

Well I'm not shooting for anything over 500 and it won't be raped on a lot so I think I'd be good. Probably won't even make it to 500 with what I'm planing 450 is more like it.

 

I think I'll asked for a quote with the girtled block, see what the price diff is, can't be to much.

 

I'm still not taking a chance. The 4.05 has lasted me about 40,000 miles so far since i swapped it in. The 6758 is ramped to come on full boost by 3900 rpms and has been fine. I want to worries when I'm making 500+whp and getting on it in 3rd lol. Anyone who has blown their F35 before will know that feeling when doing a WOT run in 3rd.

The LDK is $1900, the bare gen 3 girdled block is also $1900, so you're going to be spending more but it will be bulletproof in the long run. IDK about you guys, but I only want to build this once.

 

I think ill just go with a built ldk. I know the girdled short block would be so much better, but I don't see myself going over 450-500 whp. I'm gonna shoot for about 450 I think so ill be good. don't wanna do anything more on fwd. its useless for me.

 

well I took my head off. pistons look very clean, no signs of any damage. underside of the valves look like the motor is almost new. so I'm pretty sure my turbo is the culprit. that or the valve seals. should probably take a pic to see if u guys think it was burning oil or not in the cylinders

 

Good deal, I guess. Now what?

 

Still getting a built ldk. If this one checks out will probably sell the head at least. The block idk if I'd sell it. Don't think anyone is crazy enough to risk a second gen block nore do I know if I'd risk putting it back in the car. And I'm gonna be getting bigger turbo with the new motor so mine can sit on the shelf and look pretty, unless someone wants to risk buying it for around 500, not sure yet what I'm gonna do with everything. The head looks great, at most it needs new valve seals. Don't know what I should charge for that either.

 

Going with the 7163?

 

yup. id go with the bullseye kit but that costs to much.

 

.

Bringing this his back from the dead , I’m having the exact issue as you but with a 7163 , did you ever figure it out ?

 

I think it was his turbo and he ended up getting a different set up

 

yea I’m leaning towards turbo myself .

 

ya pretty sure it was the turbo. shaft play where turbine and compressor hit housing. I cant 100% say it was, but more than likely was. the reason I did a new setup, well besides loads of power, in the end, turbo is cheaper if it goes bad.
