2JZ questions

[han_solo]

okay i have a 2jzge and i know that the head is completely different from the 2jzgte but what else is different? any imput helps

[crono72000]

pistons are diffrent other than that not much

[4sfed180]

you have a distributor,
you dont have oil squirters,
pistons are different
oil pump is different(gte one is a bit higher flow and has provisions to mount a cas.)
upper oil pans different(gte has oil drain provision)

hg thickness is different as well.
water necks are different

what are you trying to find out specifically. there are a few more things i can probably list off.

your asking on the wrong forum. go ask/search on supraforums.com you would probablly get better answers there than here.

Why? so far he has gotten good awnsers.:hide:

some say the GE head's flow better though. i never looked into it.

[ANVIL]

i dont know. just makes more sense. i wouldnt go on honda-tech and ask about rb motors, even though there MAY be a few that are educated on them.

chances are they are way more familiar and educated that the handful that are here. and also the information would be more reliable (more than 1 person confirming answers, ect) and where you can probablly just search and its been covered a bunch on their forums

i answered because im on CL and FS and have a 2jz car :)

[han_solo]

okay the engine has no head and the seller told me it was a ge so i was seeing what i have to change to put a gte head on it....yea i know that this forum isn't the best for asking about a jz instead of a rb but its a start

[4sfed180]

just to put a gte head on it?

get a GTE hg or a boostlogic one. depending on what you want to drop the compression to. thicker head gasket is a ghetto way to adjust C/R but oh well.

you need a GTE oil pump since it holds the CAS. you will also need the gte head, harness, ecu, coilpacks, igniter, and some other miscellaneous stuff.

how much are you paying for the bottom end?

putting a motor together is usually more expensive then buying a swap. a jdm 2jzgte can be had for pretty cheap these days.

[han_solo]

well i got the block and a 91 coupe shell for my touch screen raido so i think i came out ahead since my raido only cost me 200....yea i know the swap isn't that much amymore but i wanted a project and is was a good deal i think
so i will need
oil squirters,
gte pistons
gte oil pump
upper oil pan

[han_solo]

also are the cams different.... i didn't see anyone say they were

[4sfed180]

intake cams are the same. exhaust cams are different. the 2jz-ge has a distributor and it is driven by the exhaust cam. on the 2jz-gte there is no distributor and it has coil on plug system.

[han_solo]

alright kool

Not all GEs have distributors. Only the early ones.
The pistons are 20 over in the GTE.
I believe more of the internals are different in the GTE than the GE. A GTE will hold 700WHP roughly and a GE will hold 400WHP roughly.
I have heard that the GE head flows better than the GTE head but I have no graphs to prove it.

yes the "early" 2jzge has a distributor. any 2jzge, ie past 98+, that has VVTI has coil packs.

the bore on both motors is the same. no 20 over. btw the 1jz has the same bore as well. all have 86mm bore.

VVTI 2jz, whether gte or ge, have thinner rods and IS a weaker motor.

the cranks are same. the pistons are different as previously mentioned.

GE vs. GTE flow is a long discussion.

look here for answer or at least guidance. i posted in most of that thread along with SuperRunner.

maybe you should do more research and less "i heard" learning. :)

yea i've been doing alot of reasearch.... thanks for the link thats should help
