Default 03 350Z 5.3 swap
I started my swap this weekend, not useing any kit just making custom parts to do it. I'm using a 5.3 and going with a TH350.

I'll keep this updated as I get more done but it will be slow going as I don't have much time to work on it.

Got some work done this weekend





Stock GTO motor mounts


The TH350 fits good and I'm able to use my stock trans crossmember also

Nothing yet, I need to do some fab work on the drivers side but I think I will just make a bracket.

where the red is on the crossmember is the stock motor mount bolt hole



only off around 3", think I could just fab up a bracket

Are you using the 5.3 apposed to the 5.7 or 6.0 for any other reason than cost?

The biggest thing was the $$, they are cheap and easy to find.

That would be my guess, plus a 5.3 in 5.7 trim makes only slightly less hp.
