My other little project

[turbotalon1g]

surprise ha!

Can't wait to see this done, so clean.

I'm not a big fan of swapping rotary cars, but this'll be awesome when it's done.

Do work!

Where did you get an all aluminum 5.3? Impala SS or 2007+ Tahoe?

LS motors sound eh? They sounds exactly the same as any other small block V8 I'ver heard, and they are 100x more advanced than an old SBC. I wouldn't put anything else in a car, you get so much for so little money. In fact the domestic rags have been throwing cheap ebay turbos on old worn out junkyard LS's and getting 600whp out of them with no other changes than opening up the top ring gap. That's pretty stout in my book.

And there is a TON of info on LS swaps out there, I've got a full color book in my throneroom just on LS swaps alone. It really maps out every detail of swapping them into most any chassis.

Thanks guys.

The L33 is out of certain '05 Silverados. They are not very common and often get bought up (by people like me) as soon as they hit the market. They're advantageous over an iron block for multiple reasons:

- Lighter weight (obvious)
- Slightly higher CR (9.9:1 vs 9.5:1 of a standard 5.3)
- Stronger rods (don't know the facts here but it's what everyone says)
- Flat top pistons
- 862 casting heads (almost identical to 243 (Z06) heads)

I don't know about LSxs sounding bad. I like the sound just right. Sounds like a throaty V8 to me!

The newer Tahoes, etc. come with aluminum 5.3s but they're diplacement on demand motors which is not desirable for performance, so you end up deleting the whole system which is doable but expensive after you figure in all of the little stuff. I paid $550 for this motor all together.

The people that don't like these swaps either a) have never owned a Rotary before or b) are delirious lol. My weight distribution was still 50/50 last year.

I'm not knocking it, I love LS swapped cars and this is a great project, I absolutely love it!

But I disagree on the sound, there are much better sounding V8's (e.g. Mustang, SC400, etc). Different strokes for different folks, don't be mad old man :D

You usually just need valve springs and head studs, from what i've seen haven't heard about that opening ring gap thing before.

Agreed.

ITs true, lsx motor just sounds like a beast. no refinement at all.

I saw that, apparently my 2007 Tahoe has those same LS6 style aluminum heads, but mine has the iron block. If I was doing the swap on my GSX, I'd only want the full aluminum long block as well, I just didn't know they made one for the trucks. I think the newer 6.2's are all aluminum. I'll have to go look at my book again, it lists every possible combo of LSx based on vehicle and year.

$550? Wow, it'll cost me that just to freshen up my 2.4/2G head combo that's going in this month. Hmmmmm.

This is the only way I like rotaries! lol Swapped to something else.

Awesome project.
