Issue when installing an oem oil heat exchanger on a 1.6.
Hi all,
I am in the process of turbocharging my mx5 na 1.6, and I thought it would be a great idea to add a heat exchanger (I live In Greece, but I want the oil to get up to temp faster, during winter).
I bought a used oem that came with the longer stud.
I placed the stud by hand until it couldn't go any further and installed the exchanger.
Placed the nut and just tightened slightly.
The issue is that the threads left on the stud are not enough for the oil filter to even hold in place.
So, either I am doing something really stupid, or I have the wrong stud...
I did some investigation on the net and found out that there are 3 different studs.
short stud for oem without a heat exchanger
BP4W-10-319 (longer; heat exchanger fits on some blocks)
E5B6-10-319C (should be even longer by ~1cm, which would be ok)
I assumed () I had the BP4W-10-319, as what was missing was that extra ~1cm.
Made an order to Bofi using the genuine mazda part number E5B6-10-319C, and when it arrived it was the same length......
So, I am at a dead end with this.
Actually the only alternative I can think of, is to use a the nut of a sandwhich plate instead of the oem, but first I would like to see where I was wrong and how I should do it.
That's the thicker one, came on MSM car's here in the US. I think they were called SE's elsewhere. I have one on my car, but to be honest I can't recall if it's a different stud or not. Might get you started though.
Yes, that is a thicker heat exchanger and not the standard one. If you cannot find a standard heat exchanger, I have an extra one but I think shipping and customs might be more expensive than finding one in the EU.
Perhaps you can find the longer threaded section from a Mazdaspeed as an alternative, since the larger exchanger is beneficial.
I am a sceptic on the actual utility of those dinky little things, with their tiny lines.
I used a Laminova for that purpose. On my racecar, I could sit and watch on a 0*c morning as my cold soaked racecar warmed up, the coolant temperature moved up, and so did the oil temp, lagging coolant by about 10*c. Previously, nothing I could do would get the oil up to temperature before the first lap of the first event. I defy anyone to match that performance with that the stock item. Laminova oil/water heat exchanger mounted on radiator outlet, getting coolest coolant.
You will need a decent radiator and good ducting, as the heat from the oil has to be dissipated by the radiator.
