Re: Headache and a Half -starting/rev cut

I think you are on the right path with the fuel pump. Let the car set over nite and than crack the fuel rail banjo fitting and see if you still have high pressure in the system. Sounds like the pump check valve is leaking down and the pump can not keep up with pressure and volume at higher RPM. Davew7

You can use anything for a push rod, such as a punch. As long as it be pressed against the M/C piston.

Re: 1984 AE86 4AC issues

The master cylinder push rod end goes into the booster, that end should be tilted down. The outlet is where the brake lines attach. You pump the M/C until you no longer have any bubbles in the brake fluid, then install the M/C. Now that the M/C is installed, l would try jacking up the front of the c...

Flywheel is from a FWD or MR2. Will need a new one for a RWD, the water plumping will also have to be changed or modified. Same here on the distributor cap, I've never seen one like that?

Re: 1984 AE86 4AC issues

Bench bleed, is just filling the master cylinder on the bench before installing. It lets you angle the M/C out-let ports upward while bleeding so you do not have any air trapped inside.

Re: 1984 AE86 4AC issues

It could possibly be the older rubber brake hoses, but I would still bet that you have air in the brake lines. Try using one of the vacuum brake bleeders.
Start at the rear longest brake line. Did you bench bleed the M/C for installing?

I deleted my booster, but used the stock M/C, by changing the pedal leverage. For a manual system you will need a pedal leverage in the 5 thru 7 to 1 range.

Re: 20V silvertop potential.

You are not going to gain much depending on the current diff ratio. My guess is that you will have to change to a lower diff ratio. You will probably need a 4.3 gear set, and I would also try to work in a lite Wt flywheel into your build plan. davew7

I do not think that type of vent inside the filler neck would pass emissions in the USA even back in the late 80's.

Re: Silvertop runs but loses power and shuts down

I think jondee86's idea that you have a fuel pump problems is the most likely. When the motor stops, try spraying quick start in the plastic vacuum connector on the manifold. If it runs for a second with the quick start, then you know it is a fuel issue. These fuel pumps have a limited life. davew7
