guys ,

I need to know , does your altezza fuel gauge , water temp and oil press working?

Although i got a aftermarket water temp but my fuel gauge seems to be acting funny.. It only goes up but not down . The only way to get it down to where exactly my fuel is , is to unplug my batteries. Then it'll drop to where it is suppose to be but it'll stay there.. I heard something about lowering down the voltage to the meters if you are a 1j transplant , is it true ??

there is a lot of 1jz vvti versions from the jzx100?????

there is only 1 version. the 1jzgte vvti jzx100(single turbo) and yes this will be suitable

you can put in the old jzx90 1jzgte non-vvti(twin turbo) as well.

According to my research, ABS pump, ECU & battery position is different from altezza.
Altezza's ABS have 2 types, I would prefer to use back the JZX100's ABS but its located at the other side of the engine bay.

Great to know that, I need more info on 1JZ. Actually I've already done the conversion, but its a 1JZ-FSE. Now planing to smack in a manual gbox.

According to my research, I think the JZX110 is more suitable, but the major problem is no one actually brings in. Too new & expensive I reckon.

Green: U shouldn't have delete your post, I would like to explain & learn more. Between 1JZ-FSE & the GTE is a different technology. My only concern is the fuel consumption

But anyway like I said, like I said i'm just doing some research.

I'm not sure, thats why i'm asking around for answers.
But I've discovered there are few things JZX110 & SXE10 share in common, such as:
- ABS pump
- Battery
- ECU

As for JZX100 ECU located inside the dash, unlike the JZX110 ECU position is just plug & play.

I might be wrong, but do correct me if i'm wrong.

Please refer to the picture below.

your pictures showing 1JZ-GTE and not 1JZ-FSE.
1JZ-FSE is the 'economy' version (eg.3SG v 3SF)
If running well why want to change manual gearbox or mod some more???

Hi Ninja,
I am currently using Titan on my E34 . Purchased by previous owner .
Two of them I believe it's leaking cause I can see some oil start accumulating .
Making the ride uncomfortable .

Since Titan carried two years warranty , how much does it cost to service it .

Do we need to make an appointment or I just can drop by and expect to get services by Q . ( first come first serve )


Thanks.
