My engine swap happens next week. I am going to get a PLX gauge that can display boost, WB02, and EGT. I will also be getting a Turbosmart Eboost street boost controller. Since I am doing the engine swap and getting all this stuff done it is the ideal "while we are in there" moment. Are there any other sensors I should have? - I have the dash gauge for oil level and water temp. Should I have a dedicated water temp sensor, oil temp sensor, oil pressure sensor other than what is present on the dash? I don't really want to spend any more money than I already am, so the ideal answer is "you should be good." But I really don't want engine damage and blown head gaskets so any insurance is probably worthwhile. What do you think?

Dedicated oil temp is a must, water temp is nice also but not required.. same goes with oil pressure.

For oil temp / water temp, look at the Spa Technique dual digital gauges. I have one in my car and it is very nice.. gives a digital read out of oil / water temp in one gauge, also records peak / low temps, has a high temp alarm..etc.

100% agree on oil temp. Stock gauges aren't particularly accurate for water temp and oil pressure but you're not going to be looking for minute changes in temp and pressure. The stock gauges are good enough for the major "oil pressure is low or water temp is way too high" events.

That said, I'm running boost, water temp, oil temp, and oil pressure gauges.

Thanks guys - will probably add oil temp to list.

I've seen a lot of track cars that have an extra, large, low oil pressure light - but not an additional pressure gauge. A friend of mine has a set of aftermarket gauges where you can set the backlighting color of the gauge to change color as an "alarm" as a certain set point. E.g. the water temp gauge will turn red if the temp exceeds XXX degrees.

I would also recommend knock as well, especially if you're running an aftermarket set up. It's great you'll already have EGT.

I have oil temp, pressure, water temp, AFR, boost, knock.

At some point i plan to add EGT and tranny temp, just to be comprehensive.


Good luck!

in the case of the Porsche 944 Turbo, the 'while we are in there' moment may be the first in a successive series

ultimately leading to failed marriages, fear, loathing, car-lessness, homelessness and finally, death....


may the turbo gods be with you.

Fear and loathing in 944 turbo. The bigger the turbo the less LSD needed.

unless we're talking rear-ends.

Where do you guys mount your gauges? I've already got a MBC **** and boost gauge sitting below my radio. Does anyone use an aftermarket pillar to mount these? What other options are out there for the 951?

Note that you need to be careful where your oil temp sender is located. I put mine in the drain plug. Lots of folks put them in the level block off plate, but don't trust that reading, as I believe it gets uncovered under cornering, and when oil temp readings are under engine coolant temp readings, it doesn't make a whole lot of sense.

Actually the best place is the oil drain banjo in the pan

The problem with that is that it will read higher than the average sump temperature, since it is coming from the turbo. Nearly all references to oil temperature are sump temperature. Oil will get significantly hotter inside the engine. When we tell our customers the safe oil temperature range, we are speaking of sump temperatures.

There you go. You hit the spot. You want to read the higher temp. once the sump catches up you are worse off. Kind of serves as a warning.

An oil temperature 100 degrees above normal isn't a very valuable piece of data.
