Was thinking of installing the Haltech oil pressure sensor in order to take advantage of the Platinum Pro's engine protection feature.

Wanted to see if anyone had experience with the protection, how effective it was and get a sense of if it is a reasonable compromise vs installing a high flow pump and extended sump. $400-500 for a sensor and protection setup versus $3500 for the sump and pump.

Car is a daily, and I just want peace of mind to be able to track it occasionally. I'm not fussed if a hot lap is cut short by protection if it saves the engine. Already have a wideband sensor and lean out protection.

My 34 GTR is running stock turbos at 14psi on e85, but I'm thinking of going to -9s. I've already got an oil cooler, injectors, pump and there hasn't been any head work done at all (no cams, gears, springs, retainers etc) if that makes a difference.

The only protection against lack of oil pressure is cutting ignition altogether, ie switching the engine off. Even then it is too late most of the time, especially with an RB26. This is not something you want happening on the track with someone up your arse.

Personally I think logging the pressure is more important, which the Haltech can do, you will find the pressure changes constantly but pressure should never drop too low. If it does you obviously need to sort out your sump baffling etc.

Yeah I agree that your better off lunching an engine then being involved in a major crash and writing the car off.

Have you considered an Accusump? I think these automaticly output oil when your oil pump fails and indicate that this has happened. I'm not 100% sure but think this was one of the features with these

Would be a better solution IMO. Give you a chance to pull off the road and shut the engine down, admitedly not alot of time but still better than nothing

I noticed the other day, the M3 BMW runs a similar thing standard, just a small one, perhaps 100ml or so strapped to the side of the block with a hose running up to the head.

I have been looking into these too as i have oil pressure issues under breaking and have probably already hurt the bottom end as i just ignored the warning and have done about 120 laps with it beeping at me under brakes :unsure:

Yeah I think the Accusump are a great thing, I was looking at doing a pre-lube system in mine with an electric oil pump and then found the Accusump and thought that was a better thing. But the price scared me off a bit lol. I don't have any issues driving mine around the street though so not a big concern lol

I only developed a problem since doing more track work and actually having a set of pads that work lol

I would say the damage is likely done on this engine and IF it kills itself i will invest in a better system for the next engine... In saying that i have spoken to a few that have had this issue now and it seems to be a tricky one to fix with a wet sump setup :(

In theory the Accusump works great, because it can compensate for intermittent oil pressure drops, but it all depends on the size you get and the length of time it has to take over from the oil pump

:3some:

Engine protection is generally programmed to cur revs to a certain level (3k), which I guess would still result in a big on-track slowdown.

But do you think the protection wouldn't kick in fast enough to save the bottom end?

Yep, the E9x M3's run two sumps and two oil pumps!

I noticed the other day, the M3 BMW runs a similar thing standard, just a small one, perhaps 100ml or so strapped to the side of the block with a hose running up to the head.

A well setup oil system is better then having the ECU cut power mid corner :(

Even if you by yourself on the track, having the car lose all power mid corner will upset the car and potentially cause you to spin out and run the risk of hitting something or someone hit you, as mentioned a motor is cheaper then the car

If you plan on serious track work fit an enlarged baffled sump and then overfill it with all the usual oiling mods

For a street car just fill it to the bump in the dipstick

i run an accusump and its faultless.

I also run an oil pressure switch on the oil pump as well as an oil pressure sender further down the line, both provide info to the Link g4+ ecu and if it senses the oil pressure switch has been triggered but oil pressure is still up (worst case oil pump failure, accusump discharging) then it engages engine protection and shuts it down. along with a big red light.

Not bad protection for my 20 dollar bottom end ;)

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
