My 2006 Wuerth Motorsports Build

Little update on the motor situation.

Pulled the bottom end apart and the rod was stuck in the windage tray. after pulling the broken rod and piston out, there was absolutely ZERO damage to the block. Got very lucky. Only damage was the broken rod, and the bent windage tray (which i hammered straight and reused).

Luckily, @ranman5608 had a spare gen 4 rod and piston from a spare motor. So i swapped my rings and bearing back over (all which were in good shape). and put the bottom end back together! There also appeared to be no bore wash on any of the cylinder walls as well.

Everything else internally looked the same as it did when i built the motor summer of 2022.
 
While it was apart, found some 243 heads to replace my 853 heads. Figured might as well upgrade something while I had it apart!

So i sent them over to Greg at Phoenix Cylinder Head to have them cleaned, a valve job, and my dual spring/retainers swapped over from my 853 heads!

Then last Sunday, i had an ARP head bolt break while torquing... so had to drill that out. Ended up going with head studs!

Ordered some OEM LS1/LS6 head gaskets and put these on!

prior to putting the heads back on, i decided to pull the lifter trays and drill 3/8" holes into them. This is supposed to help oil return to the pan quicker. these trays in stock undrilled form can hold up to 1/2 qt of oil!

Again, this was just me improving little things that I could while it was apart!

And after a 2AM garage session last night, the motor is back in the car!

I was thinking I took more motor pics, but I've been bad about taking pics recently!!!

Dude, you got so lucky that broken rod didn't take out the block! You're further along than I am... I'm hoping to get my block back from the machine shop today!

Also, with the smaller chamber cc on the 243 heads your CR will be higher (about 10.44:1). You will need to look at your tune again and make sure you're not too high on timing.

I’m thinking the broken rod happened when he started it with a cylinder full of gas.
 
I applaud you for your efforts to “get ‘er done” and not missing any more of the dune season.

Plan is to run an off the shelf Holley map that i can mess with a little, to get me through NY trip. After that I plan to have Steve Cole tune it.

Maybe hit up Dardan and he can do a remote tune before your trip??
 
Got the LS1 intake and new fuel rail/injector set up all buttoned up! Used ICT injector spacers in order to make the LS3 injectors work with an LS1 intake. Also had to modify my throttle cable bracket slightly. Also ordered pig tails from Amazon for the USCAR/EV6 injector type. so cut the existing injector connectors off and added these on. overall a much cleaner set up!

Also while it was apart, i decided i would remake my coolant pipe. i had made the existing one years ago and had it run under the header, and it was a pain to get the cylinder #8 spark plug out. So figured i would remake it.

it is now 2 pieces, and runs above the driver header! I will post more pics once i have it back on.
