Hi,do anyone know bout 2jz engine?is it true tat 2jz parts is hard 2 get?
cause i talk 2 the mechanic n they said tat 2jz parts the only way 2 get is by ordering.
is tat true?i thinking of putting in 2jz in my car but the mechanic told me don't it is better 2 go with 1jz..is it a good engine 2 be using??

nope, it's quite easy to find. this is the list i got from searching the web, 1jz parts are getting less and less, so i got to find alternative from 2jz parts. do some searching through the web. you'll find some interesting websites. pm me if you want a list. i'd love to get my car fitted with a 2jz but due to the road tax, i used 1jz. 2jz has more torque in the mid range than 1jz but 1jz head flows better.

2jz can use direct replacement of a 1jz water pump and fan assembly. so i think there isn't a problem of looking for parts. any one else wanna add some comments?

my personal opinion:

if you go all the way to get a 2jz for your car, why do you bother about ordering spare parts? Spare parts is around, you can get it from toyota because they are still used in some of the crown models even today, or from aftermarket part manufacturer.

If i'm playing with 2jz, i'll worried more about how i spend my money instead of how to get parts.

 

[ehaab]

is this what u meant??

..kidding man..ahhaha

 

[BLaCkHoWLiNG]

2jz ah.. err.. umm.. wat parts?

 

[rollakid]

you sure dunno lar.. see.. black black one vampire supra come out tapau ppl liau at night will auto generate and heal itself.. no need fix..

 

[BLaCkHoWLiNG]

fat vampire

 

[acbc]

No... Batman! Here comes the Batmobile. :)

 

[zan]

i think what those mechanics meant is the engine parts replacement are not as easy to get as some other engines like... 4A-GE or 3S-GE.

you still can get those parts but extra work is needed laa... that's why, network would come as an advantage.

 

[renxun]

the myth of 1jz head flows better than 2jz is a complete BS... even with the most aggresive porting job done on the 1jz head the benchmark still flows nothing close to even the 2jz head....why i say so ... bcuz im one of the stupid guy who listen to myth and after done everything only to find out the truth frm reality (benchmarking) and facts from toymods forum in australia... the reason why pl playing with 1.5j (2j block + 1j head) is when b4 u test power u open the bonet pl will stil tink .. "oh , its a 1jz...." and with 2jz in pl wil say ..."2jz ar...? main sendiri la kamu..." tak ngam category geng....

or another reason is if u are already running on 1jz ..u wouldnt want to waste things u had spend for the head of 1jz like single turbine,exhaust singgle turbo manifold nd some aggressive cams and pulley...so tats also a reason pl do 1.5j conversion as those parts cant be thrown into the 2jz head

btw i bought 2jz engine lantai complete with wiring without ecu rm3.5k.... just for the sake to modify to my 1j....

 

[BLaCkHoWLiNG]

dat's a bargain... 3.5k

 

[nokia]

nowadays 2jz halfcut from aristo is onli 5k. i found 1 in Kulim, Kedah.

 

[renxun]

sometimes things u dun need they appear in front of u cheap cheap price.. and we always tink ... nvm la .. now i dun need this.. untill the time we need ....might get into trouble of rm5k for a 1jz halfcut with manual tranny... and worst still u hold the money and u cant even find the thing u lookng for..

yep, that's what they found out. then again, the criteria for a good porting is the velocity of the flow, the volume of flow is the last thing a porter would look at. ex. you can't put together a 400cc port on a 500cid engine as it'll have too low a velocity or a 300cc port on a 650cid engine that has too high in velocity. that's why sometimes you hear complaints that a car makes less hp or torque after a so-called performance porting job.

so the concept of a 1.5jz is the 1jz has a higher velocity flow that helps a faster spool up of a larger turbo and 2jz 3litre provides the torque which is a great combination for DRIFTING. for information, 1jz head flows 215in and 2jz head flows 238in. both head is good in their own right :regular_smile:

wat is the different in vvti 2jz n the 2jz-gte not vvti?any power differents?which is easier 2 modify?

 

[nokia]

2JZ-GTE stock 280HP ( No AFM )
2JZ-GTE-VVTI stock 310HP ( wit AFM )

refer to http://www.toysport.com/Technical%20Information/spec_sheet.htm

*AFM = Air Flow Meter

All JZ-GTE engine is easily increase 10-30HP by just changing the Air Filter, Exhaust system and intercooler. If u want more of it, then u have to go for 2nd level upgrade already.

But B 4 u go further, u must understand wat u r going to do and basic theory of mods. This to avoid to b conned. A lot of ppl out the always say their products is the best around, but how much do u know them.
