2JZGTE Vs 3.8

[Mad_Trbo]

I am just looking to know the opinions of most. Which do you think you will make power with easier?

2jzGTE or 3.8

well both are expensive, but the toyota has technology thats continued until 2002.

while we have to fight with 20 year old tech that gets more outdated by the day.

in my OPINION. the toyota would be easier to make the power on.

The factory 2JZ motor is way stronger than a stock 109 block.

 

[grocerygetter]

yup.

 

[Antagon]

The 2JZ is definitely the more stout of the 2.
It'll make more power easier as you put it, but do you really want the powerband of a 2JZ? Only 20% of your power available up to 6500rpm I LOVE supra's but they have a weak a$$ power curve

 

[KevinB]

If you want a dyno queen...the 2jz. If you want Et's, the LC2.

BTW...what does a 300hp and a 800 hp have in common?






























They both run 13's

x2

but you could bullet prof a bottom end on a 109 and be just as strong if not stronger for 1/2 the cost imho

i love supras but not their price, really nice cars because many richies just throw $$$ (R&D) at it till it works.
but supra owners are to rich for their own good imho, buick grand nationals are way better values and help keep
a great buick alive.

Seems like most of the Supras that acutally race are using manual transmissions and drag radials because they can't fit small enough wheels to use real slicks, but they're still running high 9's!
2JZ FTW!
Has anyone installed a 2JZ in a Grand National yet?
Or any american muscle car for that matter?

Cost

I personally think the 2JZ is more costly than the LC2. And isn't that power curve you mention a function of your build sheet.

I haven't seen any dyno sheets on these cars, but I would imagine you make a few key changes and you could bring power in down low and hold it. Although the displacement is a key factor here 3.8 vs 3.0 - 26% more. Stroke the 2JZE, I think they can be stroked to 3.4 and work on the cam numbers. With the more efficient head one would think getting similar torque numbers or better should be a goal that can be reached.

Flow the air add fuel and torque has to come.

Oooh that would not be a good luck in my opinion!!!!

they race manual in order to claim bragging rights, not because its the fastest.

and yes lots of people have stuff those motors in american muscle, you just wont find alot of it online, that is an extremely expensive project to share for free.

They both have good and bad things about them, like anything. pending on what power level you want and your intentions, it could swing either way.

The Toyota has much more beef and has much better valvetrain potential where the v6 runs out of room with cam location problems and too short of a deck to get the most out of a race application that is squeezed to the limits. Cant get a big aluminum rod in there either. As far as cost to performance benefit nothing i can think of even comes close to the LC2 for performance for mid 10's and slower. You cant even come close with a Toyota for the same amount of $. Keep in mind the Toyota tech is way ahead of the 25 year old junk we are playing with. Toyota built that engine with the intention of it being a strong race engine. We are stuck with a 25 year old weak casting that was never intended to be used for more than about 400hp. I wonder what the engieners are thinking now that they have gone over 900hp on it

Wrong. You cant bullet proof it and a girdled 109 isnt anywhere near as strong as the Toyota with all the beef and extra mains it has to distribute the loading. Thats the problem. Guys are breaking these v6's all the time. 9.20-9.30 at 3600 lbs seems to be the limit. After that they are a grenade with the pin pulled. A lot more guys have broken blocks than will ever be mentioned. Some have broken a few. They are throw away blocks. To be really competitive in TSM you need to have access to a machine shop that will be able to set up several blocks that will all take the same rotating assembly so when the block cracks the assembly can be simply switched to another block. The Toyota could be made to run at well over 1000hp and never have a block failure. Running any of these engines upwards of 1000hp is very expensive. Its a matter of personal choice. If i was running near 1000hp id rather have the Toyota vs a stock block v6 Buick! Id be a lot more comfortable knowing the block wasnt likely to fail on me when going 150mph.

2JZ's are a nasty breed of motor. If I had to choose one or the other it would probably be the Toyota :redface: . There are more parts available for them also. But I still love my Buick until the day it rots away.
