Hi there, I'm trying to trouble shoot something and could use some assistance. I have a jza70 1jz engine in a mk3 supra and when I put a voltmeter between Fp and B+ on the check connector I'm getting a bit over 4 volts at idle. I have not done a fuel pump relay mod. Can someone check their 1J to...

Hey guys, I've never taken a turbo apart and could use some info from those who have. I'm in Canada and with our dollar taking a beating, I am going to wait a few years until I go single turbo. In the meantime, I want to "fix up" my twin turbos so they at least don't burn any more oil (spending...

Hi folks, I could really use some help piecing together what I'd need to build a single turbo kit for my 1JZ MK3 Supra. I want the Holset HE351CW. Here is what I think I'm going to need. - XSPower T3 Manifold (w/ wastegate flange) - Custom Downpipe (Only need 3" as I'm getting downpipe...

Well, my stock twins on my 1JZGTE are spent so I decided to remove them. I just spent the better part of a week removing them with the intent to put on a spare set I have however after spending way to much time removing the twins and having to use a Sawzall to cut some studs to get them off I...

I'm stuck...I have disconnected everything and I cannot get the rear Y-pipe off of the rear turbo due to lack of space (I tried a pry bar to push the engine forward a bit and the best I could do was loosen the bolt). I have everything else undone and my problems is that I cannot slide the whole...

Hi guys, Could use a bit of help on trouble shooting this...:1zhelp: I am getting code 14 after driving for about 7-8 miles (or 15min of driving). Car will drive somewhat fine until it reaches operating temperature then once I start stopping at traffic lights it will start to act up. When it...

I need to replace my coil packs on my non-vvti 1JZGTE and I found a set for sale locally that are 2JZ coil packs however they do not come with the metal bracket that the coil packs screws onto. I know 2JZ are interchangeable but not sure if I need the metal bracket? Thanks!

Hi guys, I'd like to go single turbo by this time next year however I need a bit of help achieving my power goals. I'm curious if anyone is using this kit (see below). It seems pretty reasonable price wise. My power goals are pretty modest. I'd like somewhere between 4-500whp, with boost coming...

I need to replace my 1JZ valve cover gaskets and I'm thinking of buying this Eristic 7MGTE Valve Cover Gasket on Ebay. Has anyone had any bad experiences with their valve cover gaskets (even on a 7M)? I know I need 4 more rubber grommets but I'll just buy them directly from Toyota. Any input...

I really like the idea of having the adjustability of the EDFC on the Tein line of products. I'm wondering if anyone can give me a comparison between these two Tein Products in the link below. On another note, I remember looking at an excel sheet someone put together that compared a ton of...

A little back story here, but I now own Mattjk's red supra and yes it is still smoking. The PO didn't fix the problem, however he did buy a used set of turbos from BIC in Vancouver but never got around to installing them. I'm going to swap the turbos this winter however I am not sure what...

I'm not much of an audiophile but I am installing a head unit and new speakers this winter into my 1991 Supra and I'm thinking of getting a 5 channel amp to run my speakers off of. The deck I ordered is a Kenwood KDC-BT858U, the speakers I'm getting are 6.5" Infinity reference fronts and 5.25"...

Need a bit of help. I bought a '91 Supra that was converted to a 5spd transmission by the PO. I need to return the clutch safety switches back to normal for an inspection before I can license the car. The problem I'm having is am not sure how they are supposed to be wired. I have been reading a...

Hi guys quick Q The metal plate between the body of the car and a five speed shifter the bolts do not line up on an automatic car. What was people's work around for this? I was going to try double sided foam tape for a temp solution. I didn't do the swap but changed gear shifter and discovered...

Hi guys, Been trying to find info on this for the last 30mins or so. I have a spare set of turbos and mine are starting to smoke. I want to swap them out, but I need the turbo gaskets. Does anyone know if they are interchangeable with any other engine/turbo or is it a unique part number. Does...

I'm having problems with my alarm system. The car has a non-vvti 1JZ w/ a supra 1JZ ECU running stock twins. Weird thing is that every time I use the key to unlock the door on the drivers side the factory alarm goes off and the car cannot be started for 30 minutes. I know how to reset it so that...

I have a 1st generation 1JZ and it has a new PCV valve (part number 88402 5HW) and I bought an aftermarket one for the 2JZ (part number 045-0375) which looks completely different than the one in the car now. What I'm wondering is my car has NO rubber grommet in the valve cover. Do I need one...

Hi folks, Been trying to find a thread to answer my question but with no luck. I know that the part numbers are different between the 2JZ and the 1JZ valve stem seals however what I do not know is whether they are physically different? I'm looking at buying a car that the previous owner used...

The one in the Sticky is no longer being hosted. Anyone have one they can share? Thanks!

I am looking at a few MK3 supras with 1JZ conversions and what I'm noticing is that a lot of them do not have A/C or cruise control in their car properly connected. I'm looking at buying my 3rd supra in the last 15 years so I'm looking for a car that has both these options. It will be a third...
