    Power mods and engine ?'s

    Look I don't have to explain this to you, you are not physicists or engineers. I know from experience that very often cars that had their cats removed, even older cars, ran poorly. Its not about backpressure. Its about exhaust induction, not to be confused with forced induction. The key is...

    Serpentine Belt squealing

    Just because the pump is new does not mean that it isn't causing the problem. Many new water pumps use junk Chinese bearings, and can be faulty out of the box.

    '92 lx Caliper Pistons. Press-in or Twist?

    Just make sure you have the bleed screw open, it makes it much easier to press in, and it prevents any gunk that is in the fluid from flowing backwards through the brake system.

    K&N Drop in Filter

    K&N filters have very poor filtering efficiencies, which means they let a lot of dirt through the filter media into the engine. They are known to foul MAF sensors, which your truck has, and cause valve seat and piston ring damage. There are better and less expensive options out there now...

    Power mods and engine ?'s

    True, but understand a few things. 1. It is not possible to burn all the fuel in the combustion chamber. You will always have unburned fuel in the exhaust. 2. EXCESSIVE unburned fuel will destroy a catalytic converter. You always have at least some unburned fuel in the combustion chamber...

    Power mods and engine ?'s

    What makes me say the limit is 8, because the gains would be more of a percentage of the engines factory power. Since the engine only produced 88 hp when it was new, and I find it unlikey that you will get more than a 10% increase at the most from those mods, the answer is 8 hp. Most folks say...

    Power mods and engine ?'s

    I would seriously doubt you could gain more than 8 hp with the above posted mods. Removing the cats will actually cost you performance where you need it most, unless the cat is plugged. Catalytic converters can act as induction devices. Sure they can limit the top end power a little, but only...

    Power mods and engine ?'s

    Well stated, yes, turbo swap is the way to go, but having more power is of no benefit if your car lacks the handling. I would improve the suspension and chassis or at least make sure it is in good condition before adding power. Removing or gutting the cats will do little or nothing unless the...

    changing intake

    I would recommend sticking with the stock type panel filter. Unless you are running forced induction, the stock setup is more than adequate, the stock filter will flow about double what the engine can. Putting a cone filter converters your stock CAI into a junky hot air intake which robs...

    VAM problem

    Unfortunately I cannot be of much help there, but I would recommend either doing a MAF conversion or switching to speed density. The VAM is a restriction on the intake, it makes your turbo work harder to get air. Even doing the blow through, it is restrictive, and moving away from it is a...

    A4LD vacuum modulator ok with Boost?

    I have a 2.#L motor that I will be turbocharging. I also have a built up A4LD, that I want to use with it. I know the A4LD was used on the '87 and '88 Thunderbird Turbocoupes. The A4LD uses a vacuum modulator. My question is, if anyone knows the answer, can I use a vacuum modulator with a...

    Headlight bulbs

    Thats true and I agree it can be misleading. Osram is a European bulb manufacturer. They had the Silverstar name before Sylvania did, but since they never mingled in the same markets, it was never an issue. Osram owns Sylvania, but the bulbs they make are different. The Osram Silverstar is...

    Headlight bulbs

    Silverstars have a film that makes them look whiter, but in reality, the natural color of a halogen light, which has a yellowish tint, is the best for night vision. Studies were done back in the early days of automobiles to determine what colors were best for indicators, and they found that...

    Stumbling and hesitation under boost

    Stumbling and hesitation under boost

    Ok, I found the problem, the spark plugs did not have the right gap for the boost I was running.

    stock turbo exhaust manifold???

    You obviously haven't tried the 40Bob headers. They are a log style like stock, known to be extremely durable, far more so than stock manifolds. That fitting is the EGR adapter. Not 100% sure what you are asking. I would soak that fitting in PB Blaster to see if you can't get it loose, then...

    Help with some random fixes

    For lubricating the seatbelts, both WD40 and PB Blaster are far too light. They may loosen stuff for now, but over time, they attract dust and they drain off the parts, offering little or no long term results. A better choise is White Lithium Grease. It stays where you put it, and it less...

    Stumbling and hesitation under boost

    Ok, replaced TPS, had no effect at all, but there was enough evidence to convince me the TPS was bad, it dis not have a smooth progression in voltage, it had erratic spots that told me it was due. But it has not resolved the roughness and stumbling from about 3K-4K. I do have a Gillis Boost...

    Stumbling and hesitation under boost

    Ok, while this car is not an SVO, the same principles should apply. I have a 1987 Thunderbird Turbocoupe. The problem I am having is that when full boost kicks in, the car starts to stumble, it surges a little bit, and just doesn't feel like it is giving full power. If the engine can get...
