I dynoed my car a few weeks ago and I am still puzzled why my hp drops off significantly after 6800 rpms. The cams in the car are Jun 272 exhaust and Jun 264 on the intake. Cam marks are pointing straight up and the crank is at zero. I do not have gears but most guys leave them at zero anyways...

Just got back from the dyno yesterday and I am pretty happy with the results but there is some improvement to be had still i think. Was hoping to break the 500whp mark but I only got to do 3 pulls but with another 1-2 psi that should be easy. This was done on a stock 1JZ minus bolt ons at 22psi...

I was just wondering if anyone has a JZX90 wiring diagram. If so please email me at 10secdream@gmail.com

Well I just completed my single 1JZ swap. I took the harness out of my working 1JZ car and swapped blocks to a lower mileage 1JZ. I put the engine in the car and it started up but only ran for 20 seconds and then the engine died. At the same time the battery died. I let the battery charge...

Well I just finished completing my 1JZ single turbo swap and I was hoping to fire the engine today. I pulled the efi fuse so I could prime the turbo with oil and I went to turn the motor over. At first it sounded ok and it cranked for about a second or less and then it just stopped. The engine...

I was checking over my wiring before installing my 1JZ into the car and noticed that my front cam sensor wires going into the plug are starting to fail. The wires are still connected but the insulation has broken right at the plug. I was wondering if there is a way to take apart the connector so...

Does anyone know the fitting needed to bolt to the stock fuel hardline in order to bypass the fuel dampener?

Is the factory fuel feed line (metal tube) that goes from the tank to the rail 3/8" OD?

I was wondering what are the inlet/outlet thread sizes for the stock 1JZ fuel rail. Stephen

I am looking for opinions on how to do my fuel setup. Some things to keep in mind are that I am looking for simplicity and cost effectiveness. The following are items that I acquired when I purchased my new setup and now I just have to add the finishing touches. -850cc Blitz Injectors...

For those of you using the Stinger EMS have you found your car breaking up under high boost because the Stinger is setup for waste spark? I have found that even though I gap my plugs really far down I cannot run more than 18psi without breaking up. I know there could be a number of culprits...

The time has come to make a build thread. The goal for the car is to make a somewhat reliable summer time toy that will be used for the street and the strip. My current goal is to break into the 12's but I am sure it won't last very long. Here is a little history about my car. I purchased a...

I am going for a good all round street alignment and would like decent performance and wear. I have been looking around and came up with these numbers and hope to get the car alignment sometime this week. The car is lowered around 2 inches. Front: Camber -1.0 Caster +7.0 Toe 0.0 Rear: Camber...

A local Supra owner is parting out his turbo kit and is selling an Apex'i IHI C7 with a Trust Manifold and a Greddy Wastegate. I tried to find some information on this turbo but Google somehow failed me. Anyone have any information on this turbo? Apparently it spools fairly fast for how...

Well guys I have this weird issue that is really bugging me. Sometimes the car will do it and other times it won't. For instance I took the car out at lunch today and the car was pulling hard all the way to red line and was not missing at all. Then this evening I went to take the car out and...

Well guys I hooked up my boost controller a couple weeks ago and I guess I got the vacuum lines too close to the exhaust piping. Needless to say thank goodness for boost cut:aigo: How did you guys mount your lines so they are out of the way of everything? Got pictures?

Well guys I can't figure out why I keep carbon fouling my spark plugs. I know many of you will say I am running too rich but I really beg to differ unless my wideband is very inaccurate. I am running the stock twins with 3 inch catless exhaust, hks downpipe, hks intake, hks intercooler, jdm...

Hey guys I was wondering if it was safe to use NGK6E's in my 1JZ or should I stick with NGK7E's? Reason I am asking this is that I have fouled 2 sets of NGK7E's so far. For instance, I put in a brand new set of NGK7E's last night and put about 60km's on the car. My AFR's were not too bad...

Hey guys I finally got around to driving the Supra but can't seem to get my AVCR to work. It keeps just building boost no matter how much I lower the solenoid valve duty. This is how I have the boost controller currently hooked up. I tee'd together both of the actuators and have them going...

I just got my H4 HID Hi/Lo kit in the mail the other day and I am having a problem trying to get the kit to work. I plugged the HID harness into my factory harness and only the halogen hi-beam component worked. I then tried rearranging the pins in the HID harness to see if that was the issue but...
