This is fun and I'd like to see where it goes. I count at least 50 ways to bump the LS430 up from the 3UZ kits being discussed to a heart transplant with an LS motor.
I think a totally custom 3UZ kit would be a lot of fun but you're going to cut most of your path through the forest.
I'd do it for fun and to keep me off the street for many many weekends but I think the biggest bang for the buck will be an LS for the LS. There are so many mod's for the 5.3 (or 6.2) that the problem won't be finding it will be picking. Someone on this site has documented that project and as I recall he's hitting your BHP/Torque numbers.
I have affection for the 3UZ motor for its sweet revving and overhead cams and overall good design but the frustration and patience would be severely tested. Maybe you have deeper pockets and a higher threshold of patience.

I agree i have no idea what he was talking about the whole 1000 pound engine thing also he is also clueless in the fact that anytime you take an engine apart you have to machine the block to seat the head and gasket at minimum aluminum blocks are not special every motor need a to be properly balanced and machined.
I meant h beams are garbage in general for any performance application that raises boost, compression etc there cheaper than i beams. I have facts to back this up some one on evom did a test and the h beams are weaker then i beams a shop also backed this up.
I was just using a "butt dyno man" i was hoping the hp and tq would be that high but i doubt it i was just trying to get the motor to have more go at first but i am currently looking into how much the rear mounted kit would be i am gonna see how much and if people wanna buy them i will work something with a shop help who ever wants one get one. It looks like $2500-$5000 for a tt rear mount kit for the ls430, $1500 for aem inffinity ecu. The transmission is still in question stock transmission can hold 350-400 from what i have gathered reading. I also read that lexus ecm's can handle a turbobqith out a tune on minimum boost like 3-5 psi anybody know if this true?

The 100 H.P. in a 1,000 pound iron block vs. say 500-600 H.P. in a 300 pound aluminum block is an analogy taken from a book written by an engine balancer.
When you start increasing horsepower by stroking, the engine will require rebalancing.
The lighter the engine..and the more H.P. this produces makes precision balancing even more critical.
The 100 H.P. 1,000 pound iron block is not as affected.
Can anyone on this blog explain how the reconfigured engine will be rebalanced and associated costs??
Also, has the OP or purported aftermarket kit supplier had an opportunity to familiarize himself with an engine balancing book?
How will the motor mounts, transmission, driveshaft, differential, halfshafts, wheel bearings/hubs, bushings and suspension be modified to accommodate such power?
Open differential?

And there is no solid answwer on the price theres stroker setup, the compression, how big of a stroker motor it is, whether it has forged internals, blueprinted, bore, whether its balanced, whether its honed, heat dispersion coatings way too many things to give a price. So to answer your question a $5 to a million trillion.
A motor is a motor regardless if its 5000 pound iron block or a 150 pound block made out of tuna fish cans every motor will blow up if not assembled right it does not matter what it is made out of or if its boxer, rotary, piston, or gerbil driven.
Ohh yah by the way that book talking about seems to be completely wrong so i would get rid of it the bushings motor mounts can be made of metal or polyurethane (energy suspension), transmission wither upgrade or switch to a supra tranny with adapter plate and assorted items, axles/driveshaft driveshaft shop, suspension take your pick bc, hks, tanabe, tein, sport, d2.
I am also discussing a rear mount turbo kit as well i cant change the name of the thread it is power adders i am talking about i am still waiting to hear back from some companies about the turbo kit and a 5.2-5.4 liter stroker kit.

Omg dude jesus Christ for the 16th time BRIAN COWER made the stroker kit if you have been reading my post i have covered all of the things you have listed and you dont need new wheel bearings that is beyond stupid. Okay so you seem like an expert what have you built? You seem like some one who has read a lot but has not put the knowledge to hands on use. You take your motor to a shop right, you also bring stroker kit you tell the shop the specs of your stroker kit and motor, you go over your build plans the shop machines your motor or sends it out to be machined it gets assembled within the tolerances, valve lash etc.
And there is no solid answwer on the price theres stroker setup, the compression, how big of a stroker motor it is, whether it has forged internals, blueprinted, bore, whether its balanced, whether its honed, heat dispersion coatings way too many things to give a price.

Anyways i spoke to a transmission shop they confirmed what kitabel said on this thread the transmission will hold 400hp with a decent tranny cooler anything after that it will need to be rebuilt thats $1500.
I also looked into the balance shaft removal and i think the 3uz have two? The removal increases take off and maybe give like 5-15hp free power no drawbacks except there might be more vibration in the cabin but that is it all you need is to just cut the shafts and make stubby shafts and possibly drill a hole for the oil passage i dont know i would actually have to look at it.

I think i can make a custom twin rear mount kit i will brake down the pricing
409 stainless steel piping $375, k&n filter x2 $116, greddy greddy td06 20g x2 $4400 or greddy 18g x2 $3400, assorted hardware $300, wastegate x2 $500, blow off valve x2 $500, electric oil pumps x2 $500, intercooler $250-$700 i think thats it i will compile a list of the items for the fuel system with prices as well soon as i have them.

You pointing out others misspellings using your atrocious grammar and some of the longest run-on sentences I've ever read is hilarious. And speaking of misspellings it's Brian Crower, not Cower.
I don't know where you do your research but you might want to find a new source. The 3uz has no balance shafts. Toyota already removed them for you. Your info on rods is incorrect as well. Making a blanket statement such as "h beams are garbage" proves your ignorance on that subject.
This forum is meant to be used as a resource. You came here asking for information and when others have tried to help or give an opinion you have responded with personal attacks. These forums are open to anyone and it's great to see new, younger people getting into these cars but you need to be respectful of those that are just trying to help.
Cue personal attack...

So you seem knowledgeable about the 3uz do you know what the stock intector size is? Also do you know about the fuel pump as well what the lph is? I am trying to figure out the fuel system for the rear mount turbo kit on this car and the total cost for it

Stock injector size is 275cc/min. Not sure on the fuel pump rating but it will need to be replaced if you use bigger injectors. I just recently tore my engine down to replace the head gaskets so I am quite familiar with them. The stock engine is good to over 500 hp with no modifications to the long block. A stroker kit is a waste of money with these engines and forced induction is the way to go. With doing a rear mount kit you will be giving up some horsepower for the sake of simplicity. These engines will survive with moderate boost levels but you will have issues with the thin cylinder liners at higher pressures. Only way to fix that is to use a 1uz block that has thicker liners or to swap a 4.7L from a Tundra that uses an iron block with more bore and stroke. I've been building and running high performance engines for 25 years and have learned a thing or two. The h beam vs I beam discussion has more to do with alloys, forging process, heat treating, and manufacturer than saying one or the other is superior. Each has its own benefits depending on application.

Also one more question this means all i would have to do is just swap the motor and tranny in and then run the aem stand alone then it should be fine correct did i miss anything? I know i have to figure out the speed sensors and such if i swap the tundra transmission in.
Soon as i heard cast iron block i was on board haha, i think if you swap the 2uz in the ls then the stock ecu ahould be able to handle it possibly? This totally changes the direction of this thread.

Hah thats funny coming from the guy bragging about how he can read but asked the same question three times, then he misspells itself as "itellf". There's thing you can do for your small ***** your trying to compensate for sports car? Trophy wife maybe? How about a yacht?

I have a 2002 gs430 and I have some info. regarding turbo charging and supercharging the 3uz motors. I have done both to my car. read up and youll see what it takes. their in the performance section for 2nd gen gs. "single turbo gs430" and "roots blown gs430". yes the stock ecu handles 5psi beautifully. and I just dyno'd the car yesterday and made 330 rwhp and 290 ft. lbs. or only a couple of grand.
I have asked numerous times about the balance shafts and no body answered my question so i googled it and found something that said the 3uz had balance shafts, if you know better then please share thats why i am askng these questions and i know have horrible grammar and spelling i am dyslexic, he was the one who was bragging about how good he is at reading then asks the same question i answered four times. Also h beams are weaker then i beams hence fourth garbage for performance applicIations that are over 400-500 hp, i can have some people from evo m come over and back me up on that. So indirectly calling me a idiot or moron is trying to help me? Sorry i must have missed that memo and respect goes both ways, see you did not insult me so i am not being rude to you.
So you seem knowledgeable about the 3uz do you know what the stock intector size is? Also do you know about the fuel pump as well what the lph is? I am trying to figure out the fuel system for the rear mount turbo kit on this car and the total cost for it

fuel injectors are 255cc. and the factory returnless fuel pump is produces 190 lph. at maximum output. if you go down the forced induction road you have better be prepared to continue forking over more money every time you turn around. I wound up investing six grand into my single turbo kit before I finally called it quits and ripped it all out and sold it because I didn't want to drop another three grand into a fully built transmission. Otherwise it would have never stopped. But keep in mind I bought only quality parts and did it all right the first time. no cheapy ebay parts or knock offs.
