Take the advice given. Without throwing extra fuel into the mix, an open exhaust and an FCD will just let you exceed 8.6 psi (fuel cut level) and go lean/detonate. The stock ECU also has no...

I've heard a horror story or two about cars with exhaust straps removed developing bizarre problems like electronics grounding through differentials, etc... No idea if they're true. I look at it as a...

Replace the heater core. They're inexpensive and not hard to replace. There is a panel you can access from under the driver side of the dash. I ran with the heater core bypassed for years because I...

The O2 sensor is used very little (light throttle only), so you won't see much difference. Narrowband sensors are pretty accurate around the stoichiometric ratio (14.7:1).

I'm not sure BNR would supply you with a CHRA if yours was not rebuildable, but even with the age of the parts, I've had good luck with the 3 turbos I've had. I would expect that most of the time...

Which injectors are not firing? All of them? How do you know that the injectors are the issue?

If the engine is burning some oil, it is most likely to be caused by worn oil control rings. This is common on older engines, but it isn't necessarily a major problem unless it smokes. It won't hurt...

In stock or mostly stock form, I don't think so. 6 psi on the stock timing and fuel maps should not be any problem. Load based timing.

I wouldn't call it rare. The original lines are partially rubber hose, and rubber does not last forever when subjected to 20+ years of heat. The OEM lines on my car leaked, then the rebuilt lines I...

If the starter spins every time, it is not a battery, battery cable, alternator, starter or starter solenoid problem.

If the engine cranks but does not start, the problem can only be air, fuel or...

If it is actually running, someone has done some re-wiring. The first place to check would be the yellow test connector I mentioned. If it has a piece of wire connecting the two sides, remove it,...

For the rear rotor video, it looks like the cranking speed might have dropped after the first ~10 seconds of cranking, which may explain why the pulses drop to around 60 psi.

Otherwise, both...

Like Satch asked, does the gauge ever show a lower (or higher) reading? Does it stay at 100 psi with the key in the 'ON' position, but w/ the engine off?



This is what I was thinking :). I'm...

Compression takes place on the spark plug side of the engine. It doesn't matter if the exhaust is non-existent. You're measuring from a sealed (or mostly sealed) chamber.
