Looking towards a Rebuild<Advice.

[slow_yota]

I Just got supra a few weeks ago but with the oil leaks and burning oil and low compression numbers I'd like to start looking towards my next motor for this car.

I pulled a 102K 7mge last year and its sitting in my garage.Im fine with staying N/A, More of just wanted a good running motor without issues of an old one and maybe a few hp goodies as well.

But I've been looking at a 2jzge that came into the junkyard about a week ago.[$220.00, I pull it]
For staying N/A and wanting longevity and maybe a ball park goal of 250 hp at the crank.
I know the 2jz would be easier to meet the hp goals, But is it worth the troubles of the swap ?

The build will go the same for each motor.

- strip down of the entire motor
- new rings, bearing, higher compression pistons - 0.20 over
- New oil pump, water pump, Timing belt etc
- 3 angle valve job, minor P & P, re-assemble
- Possibly a more aggressive cam
- copper HG
- aftermarket headers, cam gears.
- ARP hardware in everything
- balanced, blue printed, knife edged crank.

You get the picture, Basic rebuild with some goodies.
Obviously since the 2jzge has 26 more hp at stock the 2jz would be
easier for HP goals but Just more worried on how plug n play the wiring harness would be.

I seen you said above you wanted "Longetivity" and that it would be better
to go with 2jzge, what makes you think the 2jzge will be much more reliable than the
7mge? Answer this question.

Then you say the 2jzge has 26 more hp than what? 7M-GTE?
And it would be easier for HP goals? uhm NO, if thats where your getting at
stop right now and read up some more...

The price of a 2JZ swap is crazy, not to mention just for a 2jzge not even gte...

If you do that whole list above to a 7MGTE, not only will it be wayyyyy cheaper but
you will get much much better results...

Just the fact that its a newer engine and from what Ive read
doesnt have oil consumption and HG issues.
aside from that its a never looking engine no afm crap.
God I hate that thing.

No It has 26 more than the 7mge, Which is what I have right now.

Dont want a gte, I want to stay NA.

= NA FTW

Alright, well i mean hey if you got the money,time, and knowledge to do the JZ swap then go for it...
It's obvious you dont got the knowledge for the JZ swap since your asking but ok.

I mean your all worried about hp goals and getting aftermarket parts to increase
power but you don't want a turbo? Makes no sense to me.
Is there a specific reason?, i mean for a NA to get 250hp on a 2jzge isn't that
hard at all and definetly does not need all that done to it of what you listed,
Are you trying to prove a point to a friend? or what?

And you think the 2jzge has no problems?

 

[Evilempire1.3JZ-GTE]

I second 2JZ-GE
People have also reported being able to keep the 7MGE or 7MGTE electronics / efi system from the 7M to run it.

All you need is a 1JZ bell housing or JZ auto depending on your choice you can even use the JZ supra W58
BIC motor mounts.

You can have a low millage 2JZ-GE from 200 and up even from local junk yards.

I have the money and plenty of time.
And for the most part enough knowledge to get it done but just not every single detail.
hence why i'm asking if its worth it.

But if i can get 250-ish on a 7mge, I may go that way as well.
All depends on what would be better for me in the long run.
I just assumed that adding 50hp may be a bit of a struggle on an NA motor.

And the main reason is I'd like a bit more power but cant run a turbo in the class I run in the summer.
Ive also read that I can use most of the NA 7mge electronics on the 2jzge.

 

[I6Boost]

Ok well now that i understand everything better and others also we can start...

For just around 250hp like i said if you got the money/time/brains then do the 2jzge.

Now remember lol its an NA, not a turbo so i mean you may spend allllllll that money for that
list of things to do and you wont gain alot, For NA's its all about flow && lightweight parts.
Ex: 1pc Alum DS, 11lb Flywheel(If manual), etc etc.

Above you said "minor" P&P, i would strongly suggest you getting that head ported
the biggest possible... I mean dont go too big where its not safe but yea. Your ported head
is what's gonna make that huge difference for everything.

Your on a good track and i can definetly see you hitting 250 with a nice tune,
Another thing that will help out alot is getting an aftermarket exhaust to go with your
aftermarket headers, the exhaust is one of the most restrictive things on supras.

Heres a thread regarding to the 7MGE but %90 of it applys to the 2JZGE also.

....but cant run a turbo in the class I run in the summer.......

What type of racing?

 

[slow_yota]

Yea its a w58 so the lightweight Fly would make a difference too.
Didnt think about the one piece DS as well.

minor p & p = casting flash removed a nice gasket port match.
Ive just seen so many guys over do it and lose hp in the long haul.

Thanks for the info too.

Nose chunks:
The local track is a tirerack track.
We have auto X and figure 8.

Is there any way to enter a turbo class? I understand your reasoning, but when your driving off track you would most likely enjoy a turbo motor more. A stock 7M with a ~61mm turbo with a small exhaust housing, AFPR/ 550's/fuel pump and any type of tuning device will give an easy 300-350 to the tire and be very fun to drive will little lag.

 

[slow_yota]

I could but enter the turbo class, but most of those cars are newer Porsche 911/Carrera, Dodge Vipers, Corvette etc.
I think I would have a nicer/faster street car but just get mutilated at the track trying to hang with those guys.

I think I'd sooner save for a while.. & buy a 86-92 Turbo Supra later so I could
just upgrade the turbo, fuel etc and put my money into mods of instead of NA-T'ing it.

Right now this is My DD Though, So whatever I do will be this winter When I store/rebuild it.
the 2jz seems like the best option for me and i could just turbo that if I went with that direction as well, Couldt I ?

 

[slow_yota]

Well Did some research and thee 2jz I have is a `92 that came out of a sc300

Specs:

Base Engine Type: Inline 6 Horsepower: 225 hp
Max Horsepower: 6000 rpm Torque: 210 ft-lbs.
Max Torque: 4800 rpm Drive Type: RWD

The VVTi has:

225 HP @ 5800 RPM
220 ftlb @ 3800 RPM

So hp is almost identical, But Its a little less torquey and
comes in a bit later than the VVTi version.
I think 250/260 hp at the crank is still very do-able.So.... will still prolly build it this winter.
