The vvti 1jzs came with waste spark ignition unlike earlier 1jz and as far as i know the OEM spark plugs are dual ground electrode with .044 just like on 2jz-ge with vvti. Does with sound right at all? does anyone know how this affects gas mileage on waste spark ignition? i tried to run iridium...

Apparently people had this happen on vvti 1jzs as well as on non vvti. The ciramic brakes up at engine braking from what i could figure out and then pieces get sucked in the cylinders. is that as all possible?

maybe an easy question but will a malfunctioning or absent cam or crank sensor in 1jz cause no spart from the coils? like no spark at all

The car started out as a 5 speed N/A then transitioned to a 1jz non vvti and now i'm trying to correct the nightmare ( 0.5 vvti) that i'm stuck with. Along the way i somehow managed to find the worst 1jz shops around southern California and at the time managed to find very talented tuners / nice...

How much different 1jz-ge is from the gte brother in terms of internals? Does anyone know if that the same situation as with 2jzs? I'm thinking about a 1jz na-t possibility on a tourer-s or avante g variants of chasers, crestas, and mark IIs and maybe older crowns that are not "athlets".

Not car audio for a supra but a brand.

Hi. is it possible to create more stickies with basic parts lists and examples of proper brands of suspension parts for our cars for a particular purpose? For example Sticky 1: if you are building a drift car. do this, this, and this. good coilovers are those, those and those. Also...

Does anyone know if there are any options for aftermaket turbo for these motors? or is it the same situation as with twins?

Hi i need some help from JDM Experts. I have a VVTI 1jz with 6860 and i need to figure out if this Valcon unit is a stand alone option or not. Unfortunately USA HKS doesn't have too much info on that unit and Japanese site doesn't provide any kind of PDF installation instructions. Did anyone...

I have changed the spark plugs on my 1jz and all of a sudden cylinders 4 and 5 have no spark. the car starts and runs but very rough. changed the plugs again and its the same thing. Those two plugs are clean meaning they haven't been fired and covered in gas. i changed the coils to see if thats...

First let me say that if this post is inappropriate please move it as needed. The rules stated "cars powered by 2jz-ge" so i took a liberty to ask. I'm thinking about converting my 98 GS300 to a 5 or 6 speed manual from either a MKIII or MKIV, and would like to know the following 1. Could...

:1zhelp:I Need an advice from Cressida guys mostly but from anybody who cares to post also. I have chosen to buy a 91 Cressida and to Swap a 7mgte or 1jz with Aaron at Driftmotion. I saw this one white Cressida today with gray interior. The car is in pretty good shape body wise, the paint is...

Ok my 1jz started idling above 1000 RPM after warming up. It idles at 800 when you start it and the temp is below 180F. as soon as I start driving and it gets up to 198-200 it starts to idle between 1000 and 1300. On hot days it might get up to 1500 RPM. It seems like it depends on temperature...

I was changing spark plugs on my 1jz and two of the spark plugs were soaking in oil when i pulled them out. The whole tip was as if you dip them in oil and pull out right away. The oil looked fresh like from the bottle. Is it time for a new engine? What are my options for fixing this issue. The...

Hey everybody. I installed the 1jz intercooler from DriftMotion and man what a difference in terms of spool ease it made. The only question or issue, let say, is that the hydro fan is positioned so that it blows all that hot air right on the IC pipes on both sides. The intake side is very...

Hi everybody i'm wiring my hydro fan and there are 2 connectors that i can't identify, can anybody tell what C and D connectors are and where are they located? they connect to pins 5 and 6. thanks for any help...

Does anyone know if 1jz Hydro ECU and Camry hydro ECU identical? i know that they have different part number and harness wires are different but are the pins the same? thanks for any input.

does anyone know where the Hydro fan control unit is located. i cant find anything that would resemble it.

My 1JZ is using about a quart per 1000 miles. Oil is not leaking under the car, the exhaust is not smoking, is it time to go single? if so, is it possible to get a single turbo to make 400 hp without upgrading fuel?
