max upgrade 7mgte
 

Well, I'm looking for a way to get my engine maxed out. But I dunno what upgrades I could perform to get my engine maxed out. What conversions are possible? I heard about people going for a 1.5 JZ, what's deal? Can it be done and is it useful?

2.5L 2jz is nice and yes it can be done... the engine is twin turbo 320hp i do believe and there selling prices are 2200-2500$ U.S.


the 1jz is pretty much the same as the 7m-gte... but twins 2.5L

2jz is a 3.0l

The 1jz is a 2.5L twin turbo, and its 280 hp. 2js iz 3 L and 320. The 1jz i believe is a drop in, or takes little mods, Not for the 2j tho.

I heard about the 1jz being similar to the 7mgte. But what exact tweaks are needed? Plus I heard about what people describe as a 1.5jz. Can you upgrade an 7mgte to an 1.5jz?

have never heard of such an engine... sorry

Engines
 

The main engines that are discussed at length here are:

7M-GTE (Turbo MKIII 1986.5 - 1988)
7M-GE (N/A MKIII 1986.5 - 1994)

1JZGTE (Twin Turbo) (From the 1989-1994 MKIII TURBO)

2JZGTE(Twin Turbo) (From the MKIV)

Those are the popular ones, however my years for the model may be one year off. The beginning numbers have nothing to do with the liter of the engine, and there is no KNOWN 1.5JZ-GTE engine that I know of.

You cannot make a 1JZ-GTE engine from a 7M-GTE....at least not to my knowledge, or research. But then again, nothing is impossible, if you have enough money.

A 1.5jz is not an actually engine code, its what people call a 2jz bottom end mated to a 1jz Head.

ive actually heard of the 1.5jz engine when i was talking to a supra fanatic (he has 3 mkIII in his shop being bulit..two of them with 1jz and one with a 7mgte) and i asked him about uprgrades for my supra which he is working on (the 7mgte one) and he told me its possible...but i forgot wha part of the engine i had to change to get the 1.5jz done...buh if i can get a hold of him n e time soon ill ask him about the 1.5jz motor

Aaron will tell you, there is no way to make a 7m into a 1.5jz. BELIEVE ME ON THIS ONE.

2jz bottom end + 1jz head = 1.5jz that simple!!

well, the main thing is, I ain't got a 1jz engine even though I got a 1990 MKIII 3.0 Turbo Supra. But I read a thread were people were talking about converting a 7M-GTE to a 1JZ. And a 1JZ can be blended with parts of the 2JZ engine to get a 1.5JZ. So am I totally blind to suppose that it's possible to go from a 7M-GTE to a 15.JZ? Well , "inline6 turbo" (user name), see what you can find out plz. It would be a considerable update for the mark III.

It is possible to go from a 7m to a 1.5jz. Take out your 7m and sell it to me for free, then buy a 2jz bottom end and put a 1jz head on top off the 2jz bottom end and install it in your car. Its not rocket science. All the info is out there if you'd just look. There is a search button, use it and this is not the best forum for finding out things like this.

well, I want to move up step by step. Well, you made me curious though... why would you want a 7m if you already know how to create a 1.5JZ? Is the 1.5JZ inferior to the 7m block? Cause I thought the 1.5JZ had an higher performance...

it definitly does have a higher performance... the 7m is a good engine also though... and i may have one for sale soon, for all those interested... its got 153km on it.

that's 153 thousand... I'm guessing :confused:... Even, if I knew the disadvantages of the 1.5JZ and how to construct it (what exact parts) I could even consider ditching my 7m too.

1.5jz swap will cost $5000+ and you will still have less hp then my 7m, a lot less.

a 1jz, 2jz or 1.5jz(a combo of the 1j and 2j motors) are stronger platforms to build off in stock form. 7m is very capable of producing 800+rwhp. What are you goals?

Well, the goal is simple. To get the car as fast as it can. But... Of course, weight plays an important part in it. However, it's not only about speed, it's also about stamina. What use is a car if can't last because of over-performance.
That's why I figured hitting a 1.5 JZ would be the most useful to start from...

Whats your budget?

My budget doesn't matter really. I'm even considering a 2JZ full swap. But what I don't know is... Can my 5-speed car be turned into a 6 speed when upgrading to a 2JZ? and what do I need to pull it off.

Plus like, I was watching a show on the discovery channel (gimme a break) and they were replacing something what we call the "bridge" in our language. It's like the main bar supporting the frame... And they removed it, replaced into full aluminum. This saves alot of weight... But could it be done for an MKIII?

You would probably have an easier time saving up and buying a mk4....but maybe not. Ive heard it cane be done, But you have to cut/weld or bang out the trans tunnel, Which may mess with your interior. But the 5 speed seems fine and is plenty strong. There is a lot of work involved just to get 1 gear.

That's seems to be a pitty. Allthough I've been hearing about the v160 (from the MKIV) being fit in easily to the MKIII... Maybe someone could confirm it.

Easily? I think not...

Amen to that brother!

Duane

why do all that work for a 6th gear that just coasts the speed... makes no sense to me anyways.

not to mention any rear end ratio offered in an A70 is too high for the V160's final drive, completely defeating the purpose of switching. Unless you like rowing....

There is literally TONS of information on building a 1.5JZ, all you need to do is search.
Also, don't answer if you don't know. Plain and simple.

Good to see you Duane. We need more smarties!

Yup! thanks. I love smarties too :) I eat the red ones last

7M FTW

Duane

White smarties are my favorite, for whatever reason...
I agree, 7M FTMFW!!!!11!!1!

Smarties suck. Stupid canadians...

you three are gonna cause 7m chaos in my nice unknown forum aren't you now :p LOL

Actyally it is a 1.5jz which is a 2jz bottom end and 1jz top end, and the 1jz is not all all like the 1jz. The 1jz is 0.5 l difference, has twin turbos, shorter stroke, doesn't have hg problems, hols upwards of 800whp on stock bottom end, has a higher redline, and is way different.

I read it twice and I'm still confused.

lmao

yeps i think there's 2 very import symbols n numbers missing from that statement

but since it's a really really cool engine and wayy better then it shouldn't need to be rewritten LOL

Yup..that is Nate for ya. Damn Yankee doodle.

Duane

Your opinion doesn't count... Until you make more hp then me. Remember, Nate 667rwhp > Duane 665rwhp(w/ nos ;))
