If the factory MAP sensor did not have a hose on it when you got the car, leave it that way. The ECU might use it for barometric correction, Changing things when you don't know what they do is the recipe for a big headache !! It is usual for the ISCV to provide extra air to assist starting, and then...

There is no evidence to suggest that the ECU is not working correctly, or that it is in need of adjustment. Chances are it is simply reacting to the inputs it is receiving. Where is the WBO2 sensor located ? In one of the header tubes or after the collector ? The fact that the ISCV does not seem to ...

Head gasket is blown... pull the head and see if there is any
other damage. If you get lucky a good clean and a fresh factory
head gasket could have you up and running. Just make sure you
change the oil and filter to get as much of the water out as you
can before firing it up.

Check that the slide clip on the end of the sender wire did not fall off the pin
on top of the sender (mushroom shaped thing, front of block on exhaust side).

The "runs fine when cold and dies when hot" kind of intermittent fault is one of the most difficult to diagnose, as you can't pick it up testing the car in your garage. I am not a fan of just replacing random parts system of fault finding, as you can rack up some serious costs before you h...

Wiring diagram for the GTS shows a plug for the Brake Fluid Level Switch
being between the drivers side shock tower and the firewall. Wires should
be Red-Blk and Wht-Blk.

You need Body Plugs aka Sheet Metal Plugs...



Any decent auto parts store should have them.

A limited slip diff will be more likely to cause understeer on an AE86
than an open diff (power on, turning into a curve with both rear wheels
getting grip).

There are as many shock valving variations as there are shock absorber makers. Here is a nice big picture showing the three main designs of shocks... http://img194.imageshack.us/img194/8837/shockabsorberdiagram.png Right click and view image to see how the construction varies from one to the other. ...

SO, HOW DOES A SHOCK ABSORBER WORK ? Regardless of what colour it is or what brand is on the outside, all shock absorbers work by forcing oil to pass thru a small orifice (hole). The Laws of Hydrodynamics say that the faster you try and push the oil thru the hole, the greater the resistance will be...

REPLACING THE OEM SHOCKS As the factory front shocks are open oil filled type (similar to dirt bike front shocks), replacing them means converting to sealed cartridge shocks. http://i37.photobucket.com/albums/e54/45aken/SKR_TU6.jpg Remove the strut from the car, undo the gland nut, pour out the oil...

Wet sleeves with a wall thickness of just under 6mm according to
the guy who builds the engine. So there must be a flange at the top
for locating and retaining the sleeve.

@ Deuce Cam - Point I was trying to make is that serious enthusiasts can get shocks custom made/valved specifically for their cars, at a cost. Readymade shocks, unless they are designed for an application (like HTS) are always going to be a compromise. For example, the SW20/Camaro AGX combo I have o...

The AE86 GTS left the factory with open type oil filled front shocks and KYB gas filled rear shocks. These were quite well matched to the standard springs, and gave a somewhat firm and sporty ride. Thirty years on the factory "stance" of the car is not going to cut it with the current drif...

Starting with one thing at a time... http://i984.photobucket.com/albums/ae328/jondee1/throttlebody001s_zps956cba48.jpg Locate the AAV port inside the throttlebody, and block that hole temporarily with a rubber bung from an inflateable toy or something similar. Get the engine running and once it is w...

This is how the 16V 4AGE cooling system is supposed to work... http://i55.tinypic.com/291dkxz.gif By taking all the water out of the back of the head, you are messing with the water flow thru the head, and with the thermostat by-pass setup. Obviously your bro got it to work, but most 7AGE's seem to ...

Good work Sherlock :) It's something that happens in old cars. After a zillion flexes with the movement of the car, wires can fatigue and break... usually where they connect to some piece of hardware. Dissy and coil connections... connections to the horn and lights... anywhere that the wire hangs in...

Intermittent faults are the hardest to diagnose. Could be a dry joint in the relay, loose splice or connection somewhere in the wiring, dodgy relay in the power supply elsewhere... Best bet would be to take everything out of the supply circuit upstream of the COR by running a temporary test wire fro...

Not elegant but should work OK. The leaf springs locate the axle, the
traction bars control spring windup, and the the coil springs add a little
more spring rate to help control squat.

I've attained a few of my automotive dreams*.... a few more before I die would be nice :lol: You're a lucky man !!! I've never had the time. money or facillities to build the various cars I have dreamed of, but I have to say that putting a race engine into a road car has always been up there :) Som...

The AE86 fuel pump does not prime like a modern car. The COR has two coils, one which is energised by the ECU only during cranking, and another that is energised when the flap in the AFM opens. The second coil takes over from the first as soon as there is a enough air passing thru the AFM to open th...

Don't waste your time with modified production... just drop in a
real racing engine and have something that sounds like this....

Sorry I can't comment on how to set up MS or EDIS as I have never worked with either. There does seem to be a fairly comprehensive writeup here... http://www.megamanual.com/ms2/EDIS.htm which I guess is the manual you are referring to ? All I can say is that for the engine to start, you need to have...

If it backfires while cranking in fuel cut it is lighting off some of the fuel that is sitting in the cylinders. Basically, you have all the needed ingredients for a running engine, it is just that your spark is not happening at the correct point in the compression stroke. It might sound ugly, but I...

I'm not using MS so I don't know if this is any use to you or not ? But this is the cranking fuel settings that I use for the ECU on my 16V with quads, and it works fine hot or cold. http://i984.photobucket.com/albums/ae328/jondee1/CrankingFuel_zps6599aeef.jpg 10 deg BTDC should be OK for cranking. ...

MAP sensor normally connects to one of the three nipples on a round black plug halfway along the engine side of the intake manifold. Once the plugs get wet after prolonged cranking, it can be difficult to get them to fire. Sometimes just fitting a fresh dry set of plugs (cheap ones are all you need)...

From memory I think that you can get this kind of problem if the pistons in the brake master cylinder are not able to fully retract when you take your foot off the pedal. They need to return fully to uncover some little hole that allows brake fluid to go back into the reservoir. Likely causes are br...

How do you have 66 degrees of overlap with 256 cams??? From the HKS cam card, Intake opens at 36 BTDC and exhaust closes at 30 ATDC. These are measured at 0mm valve lift , whereas the Toda figures are measured at 1mm valve lift . Comparable figures for the HKS cams at 1mm valve lift are 2 and -4 wh...

Remove the swaybar and go a bit stiffer on the front springs.
