1jzgte VS 1ggte
|
Sun, 08 June 2003 10:26
|

firstly yes i searched for this and i have read the article on the turbo comparison.
the main things i am wondering about are the modifications that can be made to each engine and their standard/modified hp ratings.
i know the ijz is a 2.5 litre engine compared to the 2 litre 1g.
from what ive seen a 1jz is about $500 more from a wreckers/importers in a package.
cheers

how much horespower could u pull out of a 1ggte if u really tried and the same goes for the 1jz? i am buying one soon and would want the manual 1jz but if the ig is easy to work up id rather just go the the 1ggte

put it this way... i have just bought a 1G powered soarer, and though its fairly quick, im about to commence an upgrade to a 1J as its far easier to modify. There are WAY more parts available for the 1J, and even without modifying it, you'll be producing equivalent HP as a worked 1G. Makes sense to pay $500 more on a superior motor, than spend thousands on making a 1G almost as powerful.
thanks
Ben
PS- i still love the sound of a 1G, cant beat it.
PPS- by the way, its very hard to find parts for a 1G, i've looked and cant find much at all. Since the 1J is soo common and popular, there are heaps of aftermarket stuff ie: pistons, rods, etc...

The easiest way to lok at it is this .a modified 1ggte is around 200 rwhp max stock turbos and ecu .a 1j is around 300 rwhp max same setup the 1j has about 150 nm more torque as well .
if your talking aftermarket turbo ecu etc then they are failry close however that extra 1/2 a litre always counts for torque and less lag

Yeah im also in a dilemna here with 1JZ & 1G
the 1JZ would be a damn tight fit in the corona hence making it a hoare to work on.....not to mention $$$ to get in there aswell
so if i can squeeze 150 rwkw minimum out of the 1G ill be happy
i dont need THAT much torque as the corona doesnt weigh too much
just under 1100 kg ive been told ?
so for these reasons im probably leaning towards 1G
but mind u a 1JZ would make a crazy sleeper
Thanx

mani... talk to bassaholic. He has a 1J powered corona in the final stages of the build process. For all things light and street driven, go 1G. For all things heavy, (ie: soarer), you need as much torque as possible, so go a 1J.
If you really want power... go the mighty 2J!!!!

1JZ is always the pick, and rightly so. In it's favour it has:
Strength
Shorter stroke, good for some revs
Extra capacity
However, the 1G isn't all bad:
Still a damned side stronger than it's ever given credit for
Easier to fit
Lighter
Cheap as buggery (a lot cheaper than some might suggest..)
Probably better from a legal point too
Personally I'd play with the 1G just for the 'underdog' factor - they ARE tough customers, they just happen to be blessed with piss tiny little turbos etc. from the factory. A moderately modified 1G will also make a lot more than 150 at the wheels - if that's all you've got, you haven't tried!

If we're comparing engines, then of course the 1JZ will win out. It's a newer design and larger capacity.
But it also depends upon the application. A 1JZ in a Celica would not be a good idea since it'll ruin the handling. Would be awesome in a straight line and in the traffic light GP though!
In something heavier/longer like a Supra or Cressida, you'd be silly to put a 1G in when you can stick a 1JZ or 2JZ in.

I don't claim to know anything about either engine, but I do remember reading an article on the 1G.
http://www.autospeed.com.au/A_0700/cms/article.htm l
From what I can gather, a properly set-up and controlled 1G can put out some very serious power figures, even with the basic engine untouched

Alrighty . . now we have identified both engines go hard but prove better and worse in different applications, where is the best place to pick up a 1JZ or 1G half cut/engine package in brisbane that is decently priced?

Rolin Automotive Imports are highly recommended:
http://www.japparts.com.au/
Asian Auto Spares in Slacks Creek often have good prices. That's where I got my 2JZ.

Right place at the right time, that's all. I know someone who bought an Aristo front cut recently for $3500, so there are still cheap 2JZ's around.

Manipulate: your planning a 1g for the ta22 ??
Just curious - Do they fit and if so how tight is the fit ??
i thought there was engine bay length issues ..
Ive seen a 1J in a ra23 ( norbie knows the one ) and it cost a packet to do - and really was an engineering challange !
End result was an awesome car though - and its still for sale i see
Norbie - Re matts GA23 - how much was he asking for it ?

Stuart:....no the 1G is for the corona....the TA22 is sadly for sale.....as old rare cars for a daily driver are a hassle/headaches for parts
ive heard of 1G's in TA22's.....wiuthout the firewall being moved back aswell...
but seriously it would be such a hoare to work on
youd have to drop the engine off the mounts and jack it up or drop it from under the car just to do a belt
not worth it IMO.....this is assuming your gonna work on your car yourself.....and if it was my car i would.....no body cares for your car like the owner and/or close mate

I have always liked my 1g soarer but after going for a ride in my mates 1j soarer which is heavier and it just pulls a lot better. I knew i had to have one. I started trying to put a 1j in my gz20 soarer but ran out of money. Now i am nearly finished my 1jz corona which should be quite interesting. Should be drivable by this weekend, then just got to get little things like rubbers, wipers etc.
P.S hope to see as many of you guys as possible at the 12th July test and tune/ 4,6 and rotor series at willowbank!

I hope im not hi-jacking the topic, however it's along the same lines..
For all the RA28 owners / 1g Club:
When considering to put a 1j engine into the RA28 most of the threads come up with the same old,
"1J would great for straight lines etc, go the 1g"
My question to you, the weight of the 1j engine relative to the weight of the RA28 seems to have created the perception of poor handling.
A. what is the actual weight of the RA28 and the difference between 1G & 1J..
B. Possible ways of solving this problem of handling, coil-over supension, tighter strut braces panhard rods, new bushes, increased tyre size / profiles.... (big stereo in the back to balance weight distribution ? )
C. Obviously there must be some profound reasons for choosing the 1g over the 1j in many conversion of RA / TA models, apart from prices...
D. Engine management / turbo control etc etc... of the 1J.. does the instrument cluster need to be replaced in order to make this work... and what sort of computers and management are being used on these conversions?
I know Norbie has posted his link to the 1j conversion of a friend of his, but does ne one know of a 1j -> ra28 conversion that has been dicussed in detail?
Ne help is greatly appreciated... I have been convinced to go with the 1G conversion, however if the money is going to be spent and many swear words spoken during back yard conversion, it makes sense to research the 1j fully before rushing in....

The 1G transplant is well known and well documented, while the 1JZ transplant is still unchartered waters by comparison. IMO that's reason enough to go with the 1G. Engine conversions are hard enough as it is!

Do you really think the advantages of going with the 1G are worth sacrificing the extra power / potential of the 1J???
It would be a shame to go through with the 1G conversion and end up being left behind at the lights / drag strip by a crappy commodore....

as I think I said... if you're really after that much power, go the 1j. it'll be harder and mor expensive, but there's nohting worse than getting to the end of a conversion and finding out you haven't got what you want (well, except maybe having to stop half-way through because it's harder/more expensive than you thought)

That being the case then, assuming that a person went with the 1G conversion, like so many others have...
what do you suggest to improve low end response ? obviously the single ct26 wonth help with that, or even twin ct12b's...
Have many ppl taken the route of changing the internals? - I read once upon a time there was a nice fella in Ipswich willing to out fit the 1G engine with nice shiny TRD bits and pieces.. does ne one know where such hardware could be puchase or the contact for the fella in Ipswich???

Bolting a big single turbo isn't the best thing for low end response.
I'd go a nice ball bearing turbo if you wanted that.

Think about looking at some of the smaller Garrett or HKS turbos that are usually used on SR20DET's or RB20DET's. In a lot of the cases (particularily the RB) these turbos can provide more bottom-end as well as more top-end...food for thought.

Certainly is, however any power increase may require some internals would you agree?? and that becomes the next dilemma...

You won't need to touch the engine internals unless you're chasing BIG power. The 1G and 1JZ are very strong from the factory.

Yes and no, its all in the tuning. A lot of people don't give credit to the 1GGTE for its strength.
Take Phil's car for example. It hit a wall where the stock TB was too small...at 309rwhp, on stock internals. Its all in the way its done, even the toughest engine will disintegrate if not tuned properly.

Both valid points seeing as though we here that all toyota engine tend to be a little over engineered...
As for this Phil, 300kw is very acceptable, I wonder if you could talk to him and ask if he has a web site or if I could shoot him an email or two.....
Obviuously though, would I be correct in assuming that the package for Phils car would be nothing slight of expensive...

Its 300hp, which is still nearly 400hp at the fly... His setup consisted of GTR Skyline turbos. His nick on here is TRACTION_ISSUES.
Probably a good idea to put it in the first place, with 14psi Gen3 1GGTE's tend to put out between 140-155rwkW. You really think you're going to get trouble from most Commodores with this much power in a MUCH lighter car?
Match this with a proper aftermarket ECU, as with any turbo upgrade, you'd need to upgrade the support systems. You'd have urself a flyer

Point taken, although im not sure about the chance of gaining 150kw from a stock Gen 3, I dont know... to my knowledge its a little less than this?
I guess its back to searching the forums for aftermarkert ECU threads... unless ne one has some ideas of where to start looking ???

Nope, that's it. Darren just turned up the boost and pulled off the muffler and that's the result.
My car makes 124.8kW with no mods other than air filter and 2.5" exhaust. Still running the stock 11psi boost.
