WHICH ENGINE SHOULD I GO WITH?

[suprastanger507mgte]

here we go again.:nono: I think I'll just sit back and let all the misinformation flow in this one.

lol....if you open your mouth , it will just add to the cost of building it up....

FYI: I have owned my 1jz powered mkiii for a year now, and the only cost I have had to deal with is oil filter, oil change, and car washes. ( my upgrades and toys for it has nothing to do with the operating and reliability issues)

If to replace your 7m with a 1jz requires you to build it first, then you need to develop your skills on some engine shopping first.

It would have cost me the same to do the swap i think as it would have to rebuild my 7m. But then I have no idea what state the jz motor will be in. Using a motor thats been sitting all this time and boosting the hell out of it doesn't make sense if you ask me. So im rebuilding. Plus i have a lot of 7m performance parts that are no good to me if i swap. its not worth it.

So if its a choice between using a motor thats been sitting for years with xxx kms (jz) or knowing your engine is rebuilt and new (7m)...

GO 7M

 

[SublimeSupra]

Any motor cost money,all the way from big stuff to gaskets,wiring and so on.Do whatever you want you wont get a straight answer,ive heard this jz vs 7m battle all over the net ever since i have owned a mk3.But if i had the cash and didnt need this car everyday,1uzfe with twins end of story.

 

[Big Wang Bandit]

Why is this still going on?


I said 1G-GEU....

Or get a 1G-GTEU

 

[TurboWarrior]

this isn't 1j vs 7m. this is practicality/money to play with

 

[Big Wang Bandit]

a 1G is very practical. It gets around 28ish MPG!

 

[DonS1mpson]

Agreed... How much money do you want to put into this project? Is this going to be a DD? Do you want to build the motor up? All of these things are factors...

Shhh, don't let the secret out...

Out of all the 1jz swaps we have done (a lot) with used 1jz engines, none have had a bhg, or any internal issues.

It's not a 7m vs 1j thing until the people who like only the 7m start spewing misinformation about the 1jz. There are good reasons for choosing either one, but choosing 7m over 1jz because of cost or reliability is a mistake.

 

[suprastanger507mgte]

whats the cost of ex LS400 1UZ-FE's over there with LHD looms?

You can get a whole running car for 2K dollars..high miles...but still..

I think the guy meant that it's harder and more expensive to build up a 1JZ than it is to build a 7M up to a similar level.

 

[Wills7MGTE]

1JZ is better engine but is expensive to build, the 7M is too if ya want to do it right u need to build head bottom end good MHG and good fuel system, then ya need a turbo exhaust intercooler and FFIM and a engine manager, then youll need a manual swap anyway.

Id say go 1JZ I went 7M after my stock motor was found to have BHG beyond repair after I bought it.

ULTIMATELY IT'S UP TO YOU, RESEARCH THE POS AND NEGS OF IT ALL THEN DECIDE ON YOUR OWN.

 

[OneJoeZee]

what do you guys mean, 'expensive to build a 1j'? what are you basing that off of and what exactly do you mean 'build'?

 

[JustAnotherVictim]

It's expensive to "build" any engine.

 

[OneJoeZee]

^exactly. 'build' is such a vague term btw. build can be anything from a turbokit to a full tear down and rebuild with a stroker kit or something...

If you're going to say one thing is more expensive than the other, be specific guys.

:withstupi

See, this is the misinformation I am talking about from 7m guys without any jz experience.

It's the same machine work and the parts are basically the same prices for a 1jz and a 7m (some parts are even less expensive for a 1jz) It is not more expensive to fully rebuild a 1jz, and ALL the parts are easy to get and take the same amount of time to order. They are both inline 6 engines with 24 valves, why would it be more expensive or difficult to build?

LS2!!!

Ok, this non-sense about its expensive to build a 1JZ because it says 1JZ instead of 7MGTE is garbage. Its expensive to build anything! I can probably spend more money building my lawnmower motor then your motor but it doesn't prove anything. Reliability is souly depended on its owner. Any owner who beats on their car and doesn't expect something to break should just stop while they are ahead. With any car if there is poor maintinence there will be poor performance. If you do not do what you are suppose to and maintain it, it will not be reliable.

As for the thread starter, you choose what you want to do. I advise READ READ READ READ READ! Read the truth about any engine you choose by doing research. Don't believe some schmucks post because you think he is smarter then you ( no pun intended ). I have read almost every page i can find out swapping a 1JZ. I decided the cost and task is do able and i will try to do it in the next few months.

1JZ Cost isn't that much different then the 7M cost in parts. Only big difference may be turn around time thats it. With a little extra cost. For example, and engine gasket kit for the 7M is 350/400 bucks. For the 1JZ its only 150/175 and Jay marks toyota has them. Plus you can swap parts with the 2JZ. Unlike the 7M needing only 7M parts. You can custom fab but thats another story.

I have two MKIII's. 1 89 Turbo Auto in sig. 197K miles on original HQ. I have another 88 Turbo 5sp with 72 K miles. Rod knock. I guess my 89 is in better engine shape then the 88. But the 88 has a better body then the 89. How is this fixed? 1JZ in the 88 and part out the 89 .

I have beaten on my 89 almost all year long. I've put 10K+ miles on her. Long trips to AC, NYC, PA, MD and was originally purchased in Boston MASS. I plan on having a 1JZ do the same for me. Just with a different tone and kick to it. I want to experience the twin turbo 7K RPM redline.

So do the following and you will be happy

Take notes, do some math, write down a plan, then execute.

because it is made in japan and parts are hard to find and costs soooooooooooo much.:biglaugh:

hell, most of us with 1Js won't need to upgrade anything inside the engine for our needs anyway so it doesn't matter. It's already 'built' from the factory. lol

 

[TurboWarrior]

Dammit guys. He has a 7m. so its just the cost to rebuild it. to rebuild the 1J YOU HAVE TO HAVE IT FIRST. its going to cost at least double. wtf is going on in here

 

[OneJoeZee]

why would he rebuild the 1J unless it was blown?
