Exactly....because they don't break transmissions due to torque All their power is made in the stratosphere.

 

 

this thread took such an epic turn lol

 

Because they don’t spend any time at low rpm in a drag race.

 

Not entirely true, they broke plenty and now all run the same trans and clutch.

 

I don't get why anyone would spend time at low RPM, it sucks.

 

That's what happens when people who don't build boosted setups dictate how they should be done and what is "proper". On 1 hand, they claim that making power boosted is so easy and trivial and on the other hand they don't do it because its so complex for a street car and hardly worth it. PS, that was not solely directed at David. It happens on here frequently.

 

lol...careful you might kill that one guys family with all those Rpms

 

No remorse, he sounds iffy anyways

 

Right! I don't get why so many people waste time talking about, shut up and be about it!

 

The 2jz's are more efficient when you can run them at 10k rpm and 100lbs of boost! There's also a weight break in the promod class (if that's what we are talking about) when you run a smaller engine.

If I could go grab a 2jz for $500 at my local wrecker I'd be running one of them just to be unique. I ran one for a few years and loved it in an NA Sc300 I turbo'd. Currently complete engine/trans pullouts are going for $18k+ with the V160 trans. Its insane! So I'm stuck with boring JY LS stuff...

ha! A "what intake should I pick" Thread converted to a 2jz conversation... I like it!

 

We are officially on the crazy train.

 

It's pretty easy to run a SBE 5.3 at 8500RPM and 40+ PSI for essentially same power as they make at 10k an 60+lbs. I wasn't talking about promod, could care less about those.

You can get 2j without that expensive trans for way less than $18k, locally more like $3k. The trans alone is gold though, can't fathom why those things are worth so much money these days.

 

And the trans torque rating isn't even as high as a T56!

 

Ya you can buy TWO T-56's that hold up to 7 second passes for the price of one of those stock units, makes no sense.

Kinda like buying a used block, if they raise the price up to where you can get a billet block for same price why would you bother with used?

 

I think a discussion on proper intake manifold sizing evolving into a proper everything sizing discussion is perfectly on point, honestly.

Everyone has different goals, and different design philosophies/budgets dictating how they will reach those goals.

If a 2JZ turned up to 11 is right for you and your application, more poqer to you. I love the 2JZ, always wanted to find a nice way to mount a M90 on one, and put it in a Jeep. Lol.

I have no fear, or hatred, of boost, or boosting SBE LS engines. I just think the end goals should be sized properly for SBE builds... yes, you CAN hit 1000rwhp on a SBE... in my opinion, it doesn't mean you should even try.

Throw an eBay turbo on a SBE LS, please. It works, and it's apparently quite awesome. Just aim to double the torque output of whatever stock motor you are about to turbo, and size the turbo properly.

That's what this whole topic is all about, right? The "proper" size... proper is arbitrary... but I feel that some degree of common sense is, actually, relatively universal. Establishing a goal to see what amount of abuse something generic can withstand is an effort in wastefulness.

Whatever you just set out to destroy on purpose could have done someone more responsible a lot of good. Even in turbo SBE builds, if you set double the torque of stock as your goal, the average LS will live forever boosted (with a decent tune). You can learn how to fabricate, how to tune, and most importantly, how to drive a boosted ~600+rwtq vehicle for pennies on the dollar. And it can last you a good ten years in that state, if you let it.

Whenever that boosted SBE isn't enough to satify you, maybe then it is time to invest in a better, more powerful, overall combination... instead of just turning up the boost and eventually grenading an otherwise perfectly fine SBE motor...

Someone slaps a S366 on an LS1/6 in their '57 Chevy that only sees the pavement on the brightest days will last 20yrs, probably the rest of the driver's life. Lol. Same LS1/6 with an S480 might last half a dozen passes down 1320. Which is a better, dare I say, proper use of the LS1/6? Who am I do say? Proper is arbitrary...

 

So previously I believe you mentioned not having a boosted LS or not being able to afford to do it right? If I'm mistaken please correct me otherwise it seems odd being lectured on how to "properly" build a boosted LS combo by someone that hasn't actually done it.

I'm not a boosted junk yard guy although I did start with a boosted LS1 to learn on. I sold that short block before I cranked it to 11 as you say so I spared one for you LOL. I currently have a forged rods/pistons LS3 block. Even I'm smart enough to know that those people that boosted SBE junk yard motors to the moon taught others what could be done and led to product development as we learned what breaks and when. That has value to me even if I don't personally moon boost a junk yard SBE. Plus those motors are infinitely available.

Boosted forged motors don't last 20 years if you actually drive them hard on a regular basis and race them they just don't. Forged motors are built to be strong and handle large amounts of power they aren't built to run for 100,000+ miles like an oem motor.

 

I've never so much as lost a head gasket on a boosted LS. I agree don't throw in a SBE to just grenade it and start over and waste stuff. There's plenty of fun to be had south of 1000hp.

 

All depends on application and what your hobby is IMO. If your at the track every weekend, getting a year and 150+ 1/4 miles passes out of a single digit engine is an accomplishment IMO! Most of the guys running heads up small tire classes and quick bracket classes are also lucky to get a year out of an engine. Even if they do, the engine is torn down in the off season and "freshened". The freshening alone will typically cost more than an SBE long block...and if something actually breaks it can cost 5-10x as much... so you see where I'm going with this. Its not a grenade waiting to go off.... its the ability to race and have fun for a year (or more) with a $500 long block. I was on my 3rd year with the last 4.8 before selling it. So not too shabby! The more we play with them, the more we understand where to put our money, how to push them farther, and how to keep them alive longer.

 

Some of us just like working on stuff lol. Even though I have a forged motor I pulled it a week or so ago just to fix a tiny oil leak and inspect everything. Already have it back in the car just waiting on new injectors to finish it up and I work 55-60 hrs a week in a factory as well.
