Default 280z ls t56 swap help

Im currently planning a project for next summer where i want to drop a ls motor into a 280z and have noticed there are a considerable amount of kits you can buy to help drop in a ls1. how similar is a ls 5.3 truck motor to the ls1 because im curious as to if the engine mounts and stuff like that are gunna be all that different. I wanna use the 5.3 because it is simply much cheaper then a ls1 out of a camaro/trans am and puts out plenty of power for which my project requires.

Funny, I'm actually reading up a little on this same swap.. wife wants a 280ZX-LS. To answer your question, the Gen III engines (4.8, 5.3, 5.7, 6.0) share the same external hardpoints and dimensions, so either way you'll be good on mounts etc..

The Ls engines mentioned are all interchangeable in terms of parts(with exception of the 4.8 having a different crank). All mounting points are the same on all. I suggest using a ls1, ls2, or ls3 oil pan. Are you going auto or t56 ?

Nice the 5.3 is very similar to the 5.7(LS1), in terms of looks they are identical. This is what I found about the L33:https://ls1tech.com/forums/forced-in...7-l33-ls1.html

yea i feel l33 is the way to go, a tiny amount less then ls1 power and for almost a quarter the price. Im not gunna spend 1000 extra dollars for 20 extra horsepower that can be made up for cheaper in the l33 in the future.
