Remove the cover over the ecu by the driver's left foot and wiggle the connectors on the ecu while driving.
You might need someone else to watch as it's hard to see and wiggle them at the same tiem.
-
unplug the o2 sensor and see if it still does it.
-
What's the oem number on the ecu?
-
I usually use a very small dab on that small joint where the front cover meets the block because many people don't take off the front cover and I've seen a few where the front cover gasket is a couple of millimeters short of flush with the deck.

A co-worker put a kenne bell supercharger on his jeep and it came as a kit with much larger injectors.
I figured he would be belching smoke and he did..........for a couple of drive cycles and then the car ran just fine with zero ecu tweeks and continues to be a daily driver six months later.
The Jeep ecu is not to be underestimated in it's abilities......regardless of the fact that they were made with not so good components.
I've been really busy trying to hire on another technical support guy at our ecu rebuilding facility but this needs more looking into.
What I am finding is that chrysler and GM ecus are a whole lot more than most people think function wise.
That said..............anybody have a 401 steel crank?
-
Just make sure you don't run a restrictive muffler.
-
Remember that the vg30 has a crossover pipe and the stock intake manifold actually sit over part of the tranny bellhousing.
This means you will probably have to move the tranny back for any straight six swap.
-
LOL........this is a terminology argument that does not need to occur.
When I was a marine mechanic for hatteras yachts, we had both intercoolers and after coolers.
-
A lot of toyotas come with them and I replaced them every time I did a clutch as most won't last two clutches worth of usage.
If you look closely at the nissan bushing parts bag, it says "oil impregnated bearing" meaning that any wear will cause the oil that is impregnated within the bushing to lubricate whatever "liberated" it.
I've never had a factory bushing fail but once did see one that was visibly worn after 280,000 miles of usage.

I've got a L28et in a M30.

I never knew why guys would shut off the alternator on a run when you can just make sure the battery is fully charged before the run.
If battery is fully charged, you won't be using hp to keep it that way.
This allows your ignition coil to start with 13.8. to 14.1 volts rather than 12.6 volts it would see with no alternator.
That 1.2 volts can mean a lot to people with certain configurations.
-
I don't like notching the cylinders because this can focus pressure directly onto the top of the ringland rather than have the piston in the way to take said pressure.
-
Strange...........I worked on aviation and marine engines and intercooler meant cooling between stages of supercharging.
The engine itself is not considered a stage and I never heard it mentioned as such on many of the aero engines I helped restore for the smithsonian that featured two stages of supercharging.

Many years ago we experimented with a car to use for track days (car guys back in the 80s) and we boxed an a/c evaporator and pushed boost through it.
You have to be careful of the design you use as some will sound like 50 kids blowing through grass blades when you push high velocity air through them and others are weak enough that the fins flop over and stop most airflow.
Ours only energized the compressor when the brake pedal was pressed.
Since this happens much of the time on a road course, we also gained engine braking............but...........compressors don't like to be suddenly accelerated to 6500 or more rpms so it was just an experiment that would be good for a single race (maybe) but you would be hard pressed to find any sanctioning body or tech. who would pass off your car as "ok for the track".
-
Cool............you can actually be one of the few people with a true "intercooler".

I'm running a stock L24 with the turbo stuff bolted on from a 280zx turbo engine.
Running stock non-turbo injectors, stock boost level and have been for 45,000 miles on an engine that now has 270,000 miles.
I saw you on another thread asking about gasket choice but I couldn't find if the valves of the p90 hit the bores of the l24 and the only talk I see of it concerns unshrouding.
I only want to know if the valves of a p90 hit the bore.
-
So........will P90 valves hit the bores of a virgin l24 block?
-
If I'm not mistaken, that car does under 10 seconds in the quarter mile.
-
They are the same color as the 280zx injectors.

If this is a maximum effort ITS nissan engine, you will certainly be taking a bit off the head to bring the chambers down to as small as allowed by the rules or you will end up a moving chicane for all the sunbelt, B.C. Gerolomy, and Rebello drivers.
Knowing that, you will most likely be using head saver shims anyway so machining the face that meets the rocker pivots and cam towers shouldn't hurt if it turns out you have warpage of the entire head.
Talk the guys here since you will be racing them and meeting them anyway.

That will be sweet with a CA18DET.
Congratulations on doing something uncommon.
I also like that it's not another SR20DET conversion......getting bored of that.
-
The shifter can be located there but to do so in your implementation would require the shorter shift shaft that terminated within the area covered by the black cover.
-
Those automatics are pretty damn stout and come with a good enough convertor to build a bit of boost on the line.
Don't throw it away until you're sure you won't miss it.

Any of these larger seats thicker/deeper?
I have a head that got wet in a hurricane and it looks like I have a seat that got corrosion between it and the head.
Head cooling on cylinder #5 - solutions?

I'm working on a flattop f54 with p90 that will be boosted to the point of encountering this problem.
Since this engine is full of old and high mileage parts, I may substitute one or two dished pistons in 5 and/or 6 for kicks and post dyno and damage results..........might take a month or so though.
It's not the solution but more of a workaround if it works and doesn't kill power/balance.......etc.
You guys doing the research on this thread are heros and should get mucho credit (and money) if you find the fix.
