... my fuel pump relay doesn't turn on automatically(I have to open the relay and hold down the copper plate for it to move, so at least i know it is getting power to it). In an AE86 the fuel pump does not prime when you turn the ignition ON, as it does in more modern cars. The Circuit Opening Rela...

If you are lucky it should have one of these (smallport)...

Leaking injectors seals ? Leaking connection at fuel rail or
fuel filter ? Needs to get fixed, but should just be a case of
tightening up a connection, or replacing some copper washers
or o-rings.

I've got one here... done about 100,000 miles and has a bit
of wear. Measures 13.93 in the sideways direction and 13.86
in the front and back direction. I'm guessing poking it into
gear puts more load on the ball than just moving sideways
in the gate.

I am sure that you checked the timing with TE1 and E1 shorted, so you could
try increasing the ignition advance by 2 or 3 degrees, and see if it improves.

I know you should adjust the AFM but it was untapped and messed with, so i seeing if anyone knows how many turns it should be set to? The spring part of the AFM is factory set and sealed. It is not supposed to be opened up. If yours has not been opened, leave it alone. If it has been messed with, a...

This made me wonder if I could use the COP feed back signal to get an accurate reading. This (using the IGf) seems to be somewhat problematical. Since you have the "tach" outputs on your COP's you may be able to find a solution along the lines of this posting from another site... http://w...

If you are trying to drive an AE86 factory tacho you will not be able to do it directly from any low level COP tacho output. The tacho needs a voltage spike in the order of >30V, and you will only get this by using the low level tacho output to drive a transistor that switches 12V to ground thru an ...

I just grabbed a parts car that is a SR5 kouki with a SR5 rear axle housing with a TRD LSD Diff!! Yeah... apparently there was an LSD available for the SR5 way back in the beginning, but not sold for a looooong time. Kind of rare item but does get a mention in the forums from time to time. Some peo...

I'm putting this on the back burner again... just need to get a few other things sorted before I get into internal mods. But I have to say I am leaning towards custom pistons to up the comp ratio, rather than cutting the head. Is 12:1 too ambitious for a stock smallport head ? Am I likely to run int...

Hello and welcome to club4AG :) As you haven't mentioned drifting in your first post, I am going to give you the best advice I can... find another 4AC engine and get it rebuilt . Talk to your local machine shop and see if they mind you pulling it down yourself, just so you can see whats inside. If y...

... the simple facts are the 4AG head basically runs flat (flow) @ about 7.2 mm or so. To optimize the 193B's 9mm of lift you really need a good porting job. Good information. So would porting alone get be enough, or would I have to go to bigger valves ? As you say, bigger valves are a major step u...

Carbs, ITB's all the same. Screens will keep out rocks and rodents, but
the small dust is the stuff that wrecks your engine, and that goes thru
a screen like it wasn't there !!!

This... http://www.toyodiy.com/parts/diag_AI3qNo.png ... seems to indicate that you are correct. The seal is shown as a separate part, and you could not install it unless the assembly came apart as shown. I guess one part presses into the other, and by some means holds the bearing captive.

For probably a fifth or eighth that much you could make more power with a 4AGTE. Bazda from MRP has built a few 7AGTE's... I think he was making something like 360kW at the wheels at one time.

Basically, I have no problem with running an interference engine. And I do have a preference for a piston top that is as simple and as plain as possible... so the TODA style with minimum valve pockets looks good. And I would certainly look at crown and skirt coatings... lightweight pins and low tens...

... are you going to be using O/S valves? Early days yet... but I just happen to have an unopened low mileage smallport sitting in storage, and I am thinking of building something with a bit more snap, crackle and pop than my current smallport.

I was cleaning up a set of the OEM top hats a while back, and never found any way of getting the thing apart. From memory, after the bit of foam for the dust seal crumbles away, you can see the bearing from the side, and it was an open thrust type ball bearing. It looked pretty much like the top rac...

Yeah... interesting :) I just spent an hour "skimming" thru that tailbreakers thread... man, does that guy get into the details !!! Will the Supertech pistons be a full skirt like the custom Wisco, or will they be a slipper design ? Or more specifically, will they have cutouts/clearance fo...

If you are talking diff head only, then above applies. But if you are talking complete rear end... axle housing, axles, diff head, calipers and discs... yes, it will bolt in no problem. And there is a small difference in length between the SR5 and GTS driveshafts. I think you have to swap the rear h...

Since you would already have a solid 20V engine in place, I'd suggest that you investigate adding a small turbo to the 20V. Being a high compression engine, success relies on having very good control of fuel and ignition... and selecting a suitable turbo. This board member yoshimitsuspeed has had go...
