This may be the first time that AI has proved useful... :D AI Overview For a standard AE86 4A-GE ignition system using the stock distributor and igniter, the ECU does not control dwell time directly. Instead, the Toyota igniter receives a trigger signal (IGT) from the ECU and manages the dwell time ...

Some general info here... https://club4ag.com/forums/viewtopic.php?f=9&t=11437&p=76095#p76095 The charge light plays no part in the operation of the alternator. All it does is tell you that the alternator is working (or not, if the light stays ON when the engine is running). Similar informat...

Ahhhh.... sense wire is important. Regulator can't regulate correctly without it. See here... An alternator sense wire, often referred to as a "sense" or "reference" wire, is a wire connected to the battery or electrical system of a vehicle that allows the alternator to monitor t...

Your alternator will have a 3-phase rectifier so usually six diodes, What you are looking for is a "spike" of higher voltage in the rectified output, caused by the breakdown of one of the diodes. Not all multimeters will be capable of detecting the spike, but if you have a digital meter yo...

That can happen when you have a bad diode and it lets some AC leak thru. Check to see
if you have any AC ripple at the battery terminals when the alternator is charging.

Yes... all true. When cars moved on from McPherson strut and straight axle suspension designs, stuff under the car did get more complicated and fragile. But independent suspension front and rear improves the ride and handling, so that is the way that the motor industry has gone for all their upmarke...

Picked up one of these nice little wagons for a DD. 2002 model with 100,000km (60,000miles) on the clock. JDM model, RWD and runs a N.A. 2JZ-GE with 5-speed auto. I haven't had time to check yet, but some of these came with a Torsen LSD. That would be a bonus if it has one. https://i.imgur.com/Pf0hT...

Difficult to be specific about this without a bit more information... like, what igniter you actually have on the car. There a couple of possibilities depending on the year and market. Some have one plug and some have two plugs... a picture of yours would be helpful ;) That aside, if the engine runs...

Once you get the engine running, does it function normally apart from not being able to hold an idle ?? Can you drive the car, and if so, does perform as usual... no loss of power, missing, jerking etc ??? The tacho signal comes from the igniter and is derived from the back EMF spike generated when ...

So I'm dealing with an issue where I fire the car on then it keeps trying to turn over after i've let go of the key. Just to be completely clear, you are saying that when you crank the engine, the engine starts but runs very weakly. And when the key returns to the ACC or OFF position, the starter s...

Short wheelbase race cars can be quite a handful !!!!

Down here in NZ if we build a screaming 4AGE we put it to good use... no showboating on public roads !!

BC Racing AE86 BR Series Type RA apparently. No idea on compatibility with OEM springs.
However it looks like BC make adjustable perches for various vehicles. So it would be worth
giving them the ID/OD measurements of your springs and ask if they have a perch that would suit.

If you only want a small lift you could use adjustable perches with your existing springs...

I've always been a fan of the "one car that can do it all" school of thought. And admired the guys who build the sleepers... the Wolves in Sheep's clothing type of thing. The ISF fulfills that description pretty well. I've pushed it hard on a track day and am happy with the way it performs...

The 40's work well for the 4A-F. But the intake ports are maybe half the size of a bigport 4A-GE so there will be a noticable difference in air velocity there, and that's why I was wondering if 45's would be a better match. I have never played with twin-choke carbs myself, so I'm no sort of expert....

Sizing carbs or throttle bodies is mostly dependent on what you intend to use the engine for, and what other mods have been made to the engine. Everything from 40's to 48's have been used on the bigport head, in cars ranging from near stock to fully built racecars. If you were happy with the 40mm So...

Unequal length trailing links cause the pinion angle to change when the axle moves up or down. https://www.therangerstation.com/Magazine/winter2007/monstertech/monstertech15.jpg This does not occur if the links are equal length. https://www.therangerstation.com/Magazine/winter2007/monstertech/monste...

Rear steer aka Roll steer, and interesting enough to force me to consult Google, from where I gleaned this information... Cars with rear live axles, also known as solid axles, tend to not have true bump steer. Since both wheels are connected to a single, rigid member they are incapable of having any...

AFAIK the gears are there to allow the car to meet EPA standards. On the ISF first gear would be useful if you wanted to pull a plough, gears 2 thru 6 are close ratios to keep the engine on the boil when having fun :) Gears 7 and 8 are both overdrive gears so that the car can return decent economy w...

I'd suggest seeing if you can get the cranking pressure under 200psi... around 185-190psi should work with 93 pump gas. There are a lot of variables involved, and some engines will run fine at pressures over 200psi. But high pressures push the engine closer to detonation so best to start low and wor...

Check your cam timing. Intake valves are probably closing too early.

You can talk to Martelius and see if they can do something suitable. According to MRP (who sell these in NZ)... "For ease of shipping and installation, this header comes in 3 pieces and is just slipped together, then bolted in place". That might help if the header has to straddle the steer...

Sturmey Archer gears were pretty deluxe back in the day. My first bike had no gears
and a back-pedal brake. I was hardcore in those days

Looks like you got good values. By way of comparison here is a generic old school Toyota MAP sensor graph that I pulled from Toyota Autoshop. I've added the kPa values to make life easier :D https://i.imgur.com/dtkLpsP.png I don't think you are going to see 114 kPa on a N.A. engine so I would be inc...
