im not rebuilding a crap engine every 60,000 miles.. so sorry..

oh, and who are you again??:uhh:

http://en.wikipedia.org/wiki/GM_LS_engine

need i say more?? scroll to the LS4 section.. i can keep posting links..

http://en.wikipedia.org/wiki/List_of_GM_engines

this proves, there are two types of versions of the 5.3L.. ur talking about the LM7.. im talking about the LS4..

now save urself sometime, apologize, and go on about ur business and act like u never posted in this thread, and let me talk about a V8 swap w/ the guy who kindly asked about it.. and doesnt want any garbage in his thread.

Wrong, everything doesn't just bolt right up. Try to use just the LS6 intake manifold and see what happens.
Wtf is wrong with you? Can you read??? The LS4 is not a 323cid, it's a 325cid engine. It doesn't matter anyway because you don't have an LS4. You said it yourself that the engine you're getting came out of a Z71. Well guess what genius, the LS4 doesn't come in Z71's. And why would everyone want an LS1 for the name??? If the engines were the same, why would people pay thousands more just so they can say "I have an LS1". They wouldn't because the engines AREN'T THE SAME. The LS1 is aluminum and it displaces more so it has more power and comes in a package that weighs much less.
He did not make a fucking LS7. Get this into your head. THEY'RE NOT THE SAME ENGINE!!! What would the point of having two different engine codes for the same engine be? Gee, that wouldn't make much sense, would it? And how does a 5.3L gen III engine suddenly become a 7.0L gen IV engine??? Sorry, it doesn't.

Like I said earlier, you don't have an LS4. You said it came out of a Z71. Well guess what, the LS4 only came in Impalas, Monte Carlos, Grand Prixs, and LaCrosses. So how about you carry that condescending attitude all the way to the Sylvan Learning Center for some reading lessons and possibly even an eye exam?

lol, the sad thing is he will never admit, or realize his being wrong. I think most everyone knows someone like TT rotary, at least I can think of one or two...and the internet amplifies these traits!!

Thanks for the compliment. I did not cam the motor because I have read on LS1 tech that the stock cam for turbo or supercharger aps it best and easier to take a tune. I have also asked some local speed shops and they have told me the same thing. So now it is bolt ons and nitrous. But very soon to be either turbo or supercharger. What all do you have done to yours?

Awsome

The bore of the engines are different. That is what makes one a 5.3 and the other a 5.7. It would take you more money trying to make the 5.3 run like a 5.7. It could never and will never be a 5.7. It would be more or less like a 5.3 with ls1 heads and so on. Kind of like a built up 5.3. Plus things you would have to change. All the way from intake manifold, the belt drive acc. even the cam is wrong for what you are trying to do. That motor is a truck engine. The cam with the gear set up on an FD is not correct.
I am not bashing what you are tryin to do, but better to just take all of our advice and instead of wasting your money and giving it to them. Buy a LS1 the first time and do it right once. A vortc 5.3 will always be a 5.3 which equals a 325ci. C I= Cubic Inches. For example...
A 5.7L = 350 block LS1......... A 5.3L = 325 vortec. If you understand engineering you would understand that cubic inches is the converted amount of what a liter is.
Here is a list of where each engine is found and the power out put...
The LS1 shares little other than similar displacement, external dimensions, and rod bearings, with the earlier small-block V8 engines. It is an all-aluminum 5.7 L (346 in³) pushrod engine and was rated between 305 - 350 hp (227 to 261 kW) and 335-365 ft·lbf (454-494 N·m) of torque in North America, depending on the application. In Australia, continuous modifications were made to the LS1 engine throughout its lifetime, reaching 382 hp (285 kW) in the HSV's YII series and a Callaway modified version, named C4B, was fitted to HSV GTS models producing 402 hp (300 kW). The version fitted to the Pontiac GTO featured a higher-lift camshaft to produce 350 hp (261 kW) and 365 ft·lbf (494 Nm) of torque. Beginning in 2001, the LS1 received the higher-flowing intake from the LS6 and a milder camshaft to keep power at the same level; this also allowed GM to remove the exhaust gas recirculation (EGR) system (Camaro/Firebird only; 97-00 Corvette LS1 never used an EGR system). The block is very similar to that of the higher-output LS6; beginning in 2002, some LS1 engines were actually built using the LS6 block instead. The LS1 was on the Ward's 10 Best Engines list for 1998. Even after being upgraded more then 5 years ago, there is still very little stock competition for the LS1.
Applications:

1997-2004 Chevrolet Corvette C5, excluding Z06
1998-2002 Chevrolet Camaro Z28, Z28 SS
1998-2002 Pontiac Firebird Formula and Trans-Am
2004 Pontiac GTO
1999-2005 Holden Commodore Ute
1999-2005 Holden Commodore (VT, VX, VY, VZ)
1999-2005 Holden Statesman (WH, WK, WL)
1999-2005 Holden Caprice (WH, WK, WL)
1999-2004 Holden Special Vehicles (all V8 models)
2001-2005 Holden Monaro CV8

5300

[edit] Generation III
The Vortec 5300, or LM7/LM4/L59/L33, is a V8 truck engine. It is a stroked (by 9 mm) version of the Vortec 4800 and replaced the 5700 L31. L59 denoted a flexible fuel version, while the LM7 was the standard version of the engine.

Power output is 285-295 hp (213-220 kW) and torque is 325-335 ft·lbf (441-447 N·m). Displacement is 5.3 L (5328 cc) from 96.01 mm bore and 92.00 mm stroke. Vortec 5300s are built in St. Catharines, Ontario, Romulus, Michigan, and Silao, Mexico.


[edit] LM7
The LM7 Vortec 5300 was introduced in 1999, and can be considered the "garden variety" version of the Generation III 5.3 liter V8's.

LM7 applications:

2002-2005 Cadillac Escalade 2WD
2002-2006 Chevrolet Avalanche
2003-2007 Chevrolet Express/GMC Savana
1999-2007 Chevrolet Silverado 1500
1999-2007 GMC Sierra 1500
1999-2006 Chevrolet Suburban/GMC Yukon XL
1999-2006 Chevrolet Tahoe/GMC Yukon

Wow!!!! This is priceless.

tt_rotary u bought an rx-7 for it's chassis, timeless design and NOT its engine correct?

wow this guy looks dumb as well as writing crap, I think he reckons he looks quite tough in his picture but everyone else thinks he looks like a cunt and needs to grow up, has he even left school yet???? I dont think he is old enough to shave lol, he needs to be entered into the Darwin awards, all of the UK are laughing at him :rlaugh:

And you can't spell "weap", "I'm", "that's" and anyother word that might have an apostrophe in it. Not only that, but you use references that can't spell what state they live in or complete a coherent sentence.

And the displacement, material it's made of, intake manifold, cam, oil dipstick tube, exhaust manifolds, oil pan, windage tray, oil pickup tube, wiring harness, fuel rail, cam, compression ratio, and redline.

Why don't you read on the pages I posted from GM? That might give you a little more insite on the technical specs of the motor you're talking about.

No, nothing from a 5.3 of any sort can bolt up to an LS7. Sorry. Wrong. The LM7 (if you have an IRON 5.3 from a Z71, it's a LM7. Period.) will bolt up to many things from an LS1. The LS1, LS6, LM7, LH6 are all part of GM's GenIII engines. Many of their parts are interchangeable. Many are not. Just because you can swap parts doesn't make all of them an LS1.

How bout this. Why don't you roll up into your Chevy dealer's parts department and say, "I blew my motor in my Z71. I need a new LS1."

No, because it's an excellent motor.

I don't have to. The warehouse that I deal with stores motors from time to time. I've climbed on crates of them before the world even knew what an LS4 is.

http://www.gmtuners.com/LS4/index.htm

No, it's a 325. Just like every other GenIII/IV 5.3L. Please reference the previous link

And I read on a forum how little boys like to sleep with grown men.

I already have

Says who? Damn, you're dence.

You mean the part about the LS4 being a TRANSVERSE MOTOR???? Is that what you've got? Plan on converting your FD to FWD to match your Civic?

Posting a link from Wikipedia and saying "proves" is a pretty bold move.

I KNOW THERE IS A FUCKING LS4!!!! I just didn't think you would be fucking dumb enough to bring it up as part of your engine swap. With you jumping around topics so much, I really didn't want to distract you with it.

About the only thing the aluminum head/block LS4 has in common with the iron head/block LM7 (or any other GenIII/IV motor in existance) that you already admitted that you have is the displacement. THE WHOLE FUCKING BLOCK IS 1 INCH SHORTER!! Did you not even read the description from your infallible Wikipedia?

But wait... I've saved the best for last.

How the hell do you expect to bolt a T56, 4L60E, or any other rear wheel drive transmission to this engine? Their bolt pattern is different....

Attachment 704597

Please... Just please. Explain this.

And since you seem to think that everything that is posted on the internet is golden, how about this?

Attachment 704598

LS4.. 323 is a LSx based motor.. done argueing w/ u.. this thread needs to be closed.. its garbage.

Fixed.

I guess you dont hold well under the fire of being wrong. You and the information you get is what the garbage is. Go pick up a super street mag and buy a civic/acura whatever. Sell the FD to a rotary guy or an LS guy that would put the car to some use. Leave the real tunning and tech talk to the people that know the facts. Or if they dont know all the facts they ask questions or source info that is correct.
Also because something is based on something else, it does not mean it is THAT.
If the Lamborghini is based on an Audi quatro system, it does not make it an Audi.
I think this thread would do better with out your ignorance. Or if you like to be part of a community, any community be a better sport.

I can only agree. :lol:

This is great!

lets all calm down guys and keep this on topic..

:pokeowned :101384_l: :D

Whats up bud. I did not know you were on this forum as well.
I am up in the air about it. I was going to wait and see if I do the super charger or the turbo set up for it before I change it around. I know it does not have anything to do with where it is located at the moment. I still have the stock cam in it
because I have read it is better for what I am trying to do.
Where do you think I should put the FPR? Any concerns about where I put it?
Thanks for the input. Also do you have any pics of your build? I would like to see.

If you're going to use Wikipedia as a scorce, you could atleast stick with them. 325ci. GM says so, GMTuners say so, GMPP says so, Wikipedia says so....

The only ones who say otherwise is you and hiperformer.com, who, by the way, thinks the oil pan is made of TIN.

Yes, the LS4 is an LS based motor. But you've been talking about the iron head/block 5.3 from a Z71. Z71s have LM7s, not the FWD LS4. A Z71 has never and will never have an LS4 in it.

So, what is it, will you get getting the motor out of a Mustang that was originally in a Z71 or a Grand Prix?

Ill try to get you some pics this week. Sending you a pm though.

See man I told you that he is last person you should listen to. Now you know for yourself.



ouch that even hurt my feelings! lol :p:

the mustang had an engine swap, the motor is coming out of the guys street car.. AKA.. the mustang, he was gonna turn it into a drag car, but decided not to use it... he went w/ a camaro instead.. so he had his mustang sitting around w/ a perfectly good engine, that he would've sold me, the block is iron, the heads are aluminum.. its a LS4.. the motor im getting, IS a LSX based motor.. when i put it in my RX7 u will not be able to tell the difference between it, and a LS1.. its the exact same engine, except the pistons are slightly smaller, maybe a thirty thousands of an inch... u cant tell by looking at it, ill let the LSx Guru tell me.. b/c he's been doing LSx swaps ever since he's been working at his shop as a mechanic.. the only difference in the LS1, and the 5.3L LS4, is the price of the engine. Both of them push 300+ hp.. i have even looked up the pricing of a LS1 swap and a 5.3L swap on LS1 tech, all the guys agree to the SAME EXACT THING! the only difference is, the LS1 is more expensive b/c its a "LS1".. therefore the wiring.. the fuel system, ect... will hook right into the 5.3L im getting, and to answer ur question about it being a "Truck" engine, i will be swapping cams.. and doing some modding to the engine, b4 putting it into my car.. im not sure the complete list of mods, fuel system ect. everything will be changed on the motor.. the only difference is, the iron block, which i'd rather have an iron block, instead of an aluminum, the iron block can handle a lot more punishment, so much as, more HP, more Boost, than an aluminum block can.. not saying an aluminum block cant handle it.. but, it'll work better w/ an iron block, and the only weight difference is 80lbs.. that is it.. now w/ this being said, i dont think there should be anymore flaming in this thread.
