Finally got the sensors installed for my carbontrix a pillar with Defi bf oil temp and boost. I had to do a lot of cutting and sanding with a dremel tool to get the 60 mm gauges to fit into the 52 mm holes in the pillar. There is a little overhang of the gauge but it is hardly noticeable. I used double sided tape to fit the carbon fibre a pillars and ran the wires down with the a-pillar speaker wire under the dash to the glove box.

The Defi control unit and boost gauges were installed acording to evomotorsports instruction. I used the existing hole near the passanger side wheel well to run the sensor wire into the glove. You have to have skinny arms to reach it though because it is really far over towards the side of the body. To initially get it out push it into the cabin. You can use the stock black plug by punching a hole in it.

I'm still having some trouble with the oil temp sensor. I chose to use a Greddy oil block adapter(http://store.dragracing.com/product....=1152&catid=74) to install the sensor. It is a nice piece of metal and it allows a pressure sensor to be installed as well. However, it lowers the oil filter down about a half oil filter height. This puts it pretty close to the lowest thing down there and it may be a concern of being hit if you bottomed out. I'm looking for a nice 3/8 pt to 1/8 pt adapter to go into the allen bung instead. I highly recommend the 3M ultra high temp. silicone gasket that mitsubishi suggests on their evo maitanance cd to stop leaks.

looks great thanks for posting

 

Forgot to mention the gauge reading:

When I floor it down a nice stretch of road the boost goes to exactly 130 kpa (19psi). The oil temp is normally around 80 degrees C when driving around town and the car is fully warmed up. On the freeway after going 80 mph for a while the temp went up to 90.

 

how much were those defi gauges??
thnx

 

I got them from boost solutions (http://www.boost-solutions.com/DEFIgauges.htm).

Defi control unit $110
oil temp $195
Boost $215

Very nice system with high quality sensors and parts. The control unit and daisy chain gauge wiring makes additional gauges easy to install. I've read about some people having problems with the boost gauge but mine works perfect.

 

I didn't realize this information was in this thread when I posted a query on this subject in the engine forum. Thus this explains why no one replied.

Greddy doesn't give specifications for their oil block adapter (e.g. thickness, pipe thread sizes, etc). Thus it is hard to tell from the pictures how much the filter will be lowered by the adapter. I was ready to employ one of these adapters to fit Defi oil pressure and temperature sensors. You information has made me hesitate!

I found several places in the UK that have the 3/8 to 1/8 PT bushing in question. In addition there appears to be a company called Maryland Metrics that appears to have this adapter as well.

To date I haven't called them find out availability and possible minimum order charges given that I haven't received the din monitor I ordered from Quantum. If Maryland Metrics has a minimum order and the part in question maybe we can split up the minimum order...

I guess I will call them in the morning. What I want is also a T fitting to permit fitting both sensors to the 3/8 plug location.


3/8 to 1/8 BSPT adapter

 

I got mine from http://www.mcmaster.com/
Enter this part number in the search box 4860K692 to find it.
They also have t-fittings and anything you could possibly need.

 

Technically that part is a BSPT to BSPP adapter. The Defi sensors part BSPT. The Evo is also BSPT.

While a BSPT can fit into a BSPP, a JSPT (really what the Defi sensors are) cannot fit into a BSPP. The is because the BSPP standard uses a 30 degree inverse flare seat. The JSPT fitting has no flare. Thus the Defi sensor cannot seat correctly in a BSPP fitting. The only alternative is sufficient sealent for this combination and hope it doesn't leak.

 

It will work just fine and if needed it's very easy to tap a BSPP to BSPT.

 

For the cost of the tap and the adapter a call to the Maryland people to obtain the exact part makes sense. They have a walk in store so if all else fails I pick one up in Baltimore.

 

Both parts on the greddy oil block adapter are 1/8 bsp. It sucks that it hangs down too much.


I've contacted a vendor for adaptall (http://www.adaptall.com/F-MetricConversion-brass.htm) who carries the exact correct fitting (3/8 BSPT to 1/8 BSP, part number 8038-06-02) but they have a $20 minimium order (about 5 adapters worth). I'd be happy to go in with someone.

The T with the defi temp sensor may be a hassle because the sensor is so long that it would block the pressure sensor. If you're going to go with a lot of fittings coat the threads with the 3M ultra high temp silcone or you'll probably have leaking problems. I ordered it from this boat store(http://www.shipstore.com/ss/html/MMM/MMM08672.html).

 

I'm just posting info. Use or not don't. Someone may find it usefull in the future. There's no minimum on orders from McMaster's. You can order just 1 adapter. They'll ship it in the most feasible and cheapest way.

 

Are you sure about the Adaptall fitting? It reads as PT to PP.


The following are a few links from a UK company that appears to have the right stuff. Note they use Java so these links might not work (will not is more like the answer). So you might need to look for these.

Here is an offset 1/8 BSPT T that I believe will permit the temp sensor to come in from the top and the pressure sensor from the side.

T fitting

(Offset Male Taper Leg Tee - P/N N16318)



Next a reducing fitting from 3/8 BSPT to 1/8 BSPT will permit the T cited above to fit into the Evo's oil filter plug.

Reducing Bush

(Reducing Bush - Taper - P/N N1403818)



If only one sensor is to be used, only the reducing fitting is the answer.

Thorite claims that they will ship world wide.

 

Fittings look good. I guess it all depends on how big the T is inside whether the temp sensor would block things for the pressure sensor. I think I'll try to place an order for both and see what happens.

I'll also try to get some pics of how far down my oil filter is. Some people might not be concerned and choose to use the greddy block.
