My other little project

[DavidPHumes]

Some of you might know that I'm building this, but I've kept it on the relative DL in MN lately as I still want to surprise a few folks!
















Engine is coming out this weekend and then the bay will be getting resprayed. After that I basically just need to slap it all together and get a tune on it!

[Goat Blower]

Now that's more like it. I've seen a gazillion DSM builds, but the LSx stuff in cool japanese stuff really intrigues me. Makes me want to pull the 5.3 out of my Tahoe and slap it in my GSX or Lotus.

[JET]

Looks like fun! How exactly does the exhaust go? Looks like it goes to the back then links up and comes back up front to the turbo?

[asshanson]

Which LS motor is that?
Cubes?
Cam specs?
Iron or Aluminum block?
Turbo specs?

MOAR details!

Don't find many single turbo LS setups, hope it doesn't sound like a Subaru with the unequal length exhaust lol.

Thanks! These motors are ridiculously awesome. Cheap, reliable and they hold a lot of power!

Open downpipe

5.3L L33 (all aluminum), 9.9:1 CR, LS6 cam (204/218), Turbonetics TC76 (.96A/R, journal bearing, 65mm turbine wheel).

It's a completely stock, untouched 50k mile bottom end with ARP head bolts, LS9 head gaskets, Patriot Gold dual valve springs and an LS6 intake.

And thanks... I'm not sure what it's going to sound like but even with the open downpipe it's probably still going to be pretty quiet.

The way you talked about this in your other thread it was a runner/driver. Get this thing finished up, will be cool to see!

[Halon]

Fuggin sick. I wish I was smarter and knew how to do swaps like this.

And Andrew, it's an LS motor so chances are its going to sound kinda meh... I love the motors, just wish they sounded better lol. Personal preference I suppose. But awesome build man!!

Thanks! It actually was a runner/driver last summer, just with a 400RWHP LS1 and a T56 6-speed

Honestly, I came into this swap having never done anything with cars, so it's not rocket science. It's all been done before!

[Constant_Project21]

Now this is cool I enjoy LS swaps immensly! If my DD didn't just catostrophically break, then I'd be looking for something fun to swap. Someday I guess haha. Good luck with the project, can't wait to see it finished!

[A//// Guy]

Saweet project!

[turbotalon1g]

surprise ha!

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

[cmspaz]

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.

[DavidPHumes]

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!

[DavidPHumes]

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

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.
1UZFE will drop panties.

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.

[DSMINMN]

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

Awesome project.
