Hello,

I bought another rx7 a few months back that came up cheap considering what it had done.

Any how the engine in it had bad compression on all the rotars of 4.8 to 5.1.

needless to say I went looking for a new engine, I found a new engine with good compression of 7.5, that was fitted and then the car was mapped by PIP at 282bhp with a new apexi fc ecu as the previous ecu was chipped by knight sports in Japan and I didn't want to risk running the wrong fuel octane.

Any how the car has been fine but the second turbo was burning through oil which it was doing at the time of mapping hence the quick map just to get it fitted, it was definitely the second turbo as it only did it when the second 1 was engaged and the car was floored. So after failing to find the parts to rebuild it, I bought a second hand turbo from a reputable dealer (Jimmy's) for £250.

This was fitted Thursday, I took the car out for a drive and when booted it still smokes heavily. I figured it was just old clogged up bits in the exhaust, how ever when I got to the garage I revved it hard to show the mechanic.

Here is what happens, it puffs out a little bit of blue smoke, but then that blue smoke is followed by a huge amount of what appears to be white smoke, this continues to poor out while the car idles unless I give the car a slight rev (about 2-3k) and then it clears. Which to me indicates a water leak of some kind from the second turbo?

My thoughts are this, either I am incredibly unlucky and paying for the sins of a past life (maybe I was Judas) and the new engine has blown a seal in under a 1000 miles since fitment.

my new turbo has a water leak if that's possible, assuming the white soke is water.

or it has a bad map as it turns out the water temp sensor was faulty, (but I don't think it was faulty during the map)

When booting the car the road behind is literally a cloud and it will continue to smoke when I let off the revs unless I give it a small rev keeping below the 2nd turbo's rpm.

The car does not smoke at all prior to hitting around 4500 rpm, it doesn't struggle to start and it didn't loose water prior to the new turbo being fitted, I have not checked since the new turbo but I assume it will be doing as the water has to come from some where. Any help greatly appreciated I am literally out of money at this point.
