    ITBs and emmission/vac system design and questions

    If you have it stick straight out instead of bending it 90 degrees it would suck in more air since the vacuum won't be bouncing around.

    1200 rpm idle, is there any..

    I found a bunch of air hoses on mine that were all taped together and cracked. It was idling at that rpm too ever since I got it. Hopefully replacing them will solve the problem.

    These 4 big-a** bolts on top of head. Wat are they?

    I'm trying to change out my super awesome valve cover gaskets and discovered that the spark plugs have oil all over them where the wires supposed to go and there are these 4 huge bolts on top of the head that is holding down a plate where the spark plug wires sit. Now my question is: Is it...

    Light Gurus? What is this light that keeps coming on and off

    The Temp was getting pretty HIGH up there. I looked at the coolant and it looked like mud. Apparently the previous owners prob haven't done a flush in the last 20 years.

    CNC'd TEMS buttons

    I took a CNC class. Its actually not hard to make unless its plastic because you need a hydro jet to cut that.

    Impact gun. 650lbs-ft-Tq, Engine Hoist, 2-4 ton jack, your basic metric tools, some pliers and a Shoe. Yeah a shoe! I actually my NewBalance shoe when I'm needing to jack up the engine to put in a motor mount or change something on FWD cars. Helps cushion the engine against the metal jack. You...

    7M-GE wiring problem.

    The injectors all get 12V when the key is turned on from the EFI relay. The ECU just grounds them out. The AFM actually acts as a switch for the Fuel Pump Relay. Turns it on and off.

    88 OEm Cooling Fan relay size???

    1 fan runs around 10 amp, 2 fan 20 amp. 3 fan 30 amp. To be safe a 40amp relay should work. But no guarantees since im looking at an aftermarket electric fan.

    1j swap

    The wiring is a bitch. I have done it before and It is not fun, not to mention when your friend decides to use aftermarket injectors that are stuck closed. You can use the stock R154 tranny. But in order to get your Tach to work right you need to limit the current heading out of the Igniter. I...

    Electric Fan: Gaugeing Intrests

    I just got a MK3 Supra 2 weeks ago and realized how dangerous the fan was since mine didn't come with the fan shroud. Not to mention the amount of power it robs, although I am not sure how much. I was thinking of using an E-bay fan shroud that was built for the 7M radiator and bolts direct...

    Anyone put a Soarer 1JZ into 89+ supra?

    I have the whole uncut harness, and can figure how to splice the wiring from the pinouts but its those damn pins that connect to the harness of the body on the soarer that I can't figure out. So far, I could make the car start, gauges work, tach work and ECT. But things like A/C or Abs, or...

    Anyone put a Soarer 1JZ into 89+ supra?

    Hey, Im wiring that sucker into my friends 87 Supra as well. So far I have collected a few data and analysis on the Soarer 1J. But the body harness has so many wires that I have no clue what some of them are supposed to do! "Way more then the 7M itself." The biggest problem is that the soarer...
