1jz vs 2jz - Drifting forum

Nicolay · 12-03-2008, 19:47

Hi guys! Next winter I'm doing a JZ swap in my r32. But I don't know if I should choose the 1JZ or the 2JZ. concidering the weight the engine will be pushed back atleast 30cm (like the DW s15) to maintain a respectable weight distrubution. Will everybody post their pro's and con's for both engines?

Cheers

Nico

Why would the jz give you worse weight distribution than the RB? Thought they were similar weights.

Check out toymods.com as they are a big forum which would probably have the answers.

thanx m8

the jz's don't give a worse weight distribution than the rb26 but i still think it's too noseheavy. so if I move it back, it will be better.

read this:Toyota JZ engine - Wikipedia, the free encyclopedia

so you can put these in the 180sx and expect better power then yes?

and Old school i didnt mean jay-z mate.

DR1FTER · 12-03-2008, 20:50

either both excellent engines or do a 1.5jz best of both worlds then

From what I've heard (no 1st hand experience tho) the 1JZ is pretty gutless in the Torque department compared to the 2JZ so if you have the choice i'd go with the 2JZ.

Nicolay · 12-03-2008, 21:12

see many of you say 1.5jz. that's still a 2jz engine block with the 1jz top. aka it's still a 3.0liter but what makes it better then a 2jz?

Yeah this only makes sense if you are going for the 1jz, and then want a extra 500cc

I take it you've never a driven either, not much in it tbh, both make respectable grunt in stock form, with low down with spool up from 1500 rpm with stock tubbies. The 2JZ is an uber monster for power low down at the expense of only a single turbo at the top end. They are both shit fast compared to a stock SR for example.

A bit of tweakage & single tubby conversion they are both awesome engines, my 1JZ makes 1 bar at 2.5k rpm with a big turbo & is as responsive as hell, probably more so than you actually want to get the power down.

However they are cheap for a reason, they don't blow up as a rule, but you Neeeesaan boys won't like that at as you'll lose the I've blown my engine X times kudos & its considered a bit gay to not blow at 2 or 3 engines per seasons. So move on now leave the JZ for my projects & they'll never work in S bodies the wieght distrubution is all wrong & its gay just

MJG · 12-03-2008, 23:57

Leave me a couple of 1JZ engines too, will be needing them next year haha. People should definately stay away from them as they are obviously not what you want.... lol.

Two_Sheds · 13-03-2008, 00:38

Why are 1JZs so (comparitvely) cheap? What cars did they come in as standard over here?

d1fury · 13-03-2008, 07:52

1JZ's are lighter than a RB26... and a RB26 is ment to be the lightest RB so.. you do the math.

Ted · 13-03-2008, 08:05

I thought the RB20 was the lightest and the RB26 was the heaviest?

cptsideways · 13-03-2008, 08:06

JZ's are cheap cos' there is no demand for replacement ones, you know that funny rattle neeesssaaaans do well the JZ's did'nt feature that option

LOL, I seriously doubt that. My 1JZ is pushing 400 bhp and over 630 Nm of torque. And that's on twin GT28's at only 0,95 bar.
So I'd hardly call that gutless. Even with my previous stock twins, at 1 bar, it did 330 bhp and 550 Nm.

cookwibble · 13-03-2008, 16:55

gutless??? no. a standard 1jz will pretty much destroy any RB engine for torque and tunability.

the reason they are cheap is cause there is no demand, they break rarely. manual gearbox will be your only headache, but thats not going to be too bad.

great engine, your only problem will be that your neeeesahn will fall apart from the torques or just rust away to nothing before you can get the engine in
