Hi..

I did a search, but could not find an exact same problem as I have with my FD.

It is a stock FD, exept from a rear muffler.

My problem is that when i rev's the high rpm in neutral, lot of white smoke is coming out of the exhaust. There is also coming some smoke when i drive in the high rpm. It drives ok up to aprox. 4-4500 rpm and then it does not feel like it acc so strong anymore. To me it sounds like there is something wrong with the secondary turbo because it pulls strong up to 4-4500 and then dies out and the the white smoke is coming.

The FD has not been driven for a long time. It has been in a garage for 1 ½ year and just been driven 1-*2 times for that period. Could that have something to do with my problem..??

I have been driving in it for 20 min just to get the engine warm and it still do not drive as it should...

I hope somebody can tell me what to do so I can get it to work fine again...

Sounds to me like your secondary turbo oil seal is going, is it just a puff of white smoke at gear change under boost?

Oil is blue smoke. White smoke is coolant. Either your water seal is gone on the rear turbo or your motor has a seal thats going.

I have another video I am about to upload to youtube. I think it is ready in 10 min.

The compression is exactly the same on the front and rear, so I don't think there is something wrong with the inside of the engine.

Yes i know the white smoke is coolant but i have to find out where it could come from...

Here is the video where I rev the rpm at the start, and you can see the white smoke come out of the exhaust...

Wait a minute, I'm confused. You have a single turbo car but are wondering if your secondary turbo is shot? According to your sig you have a hks T51r turbo. Is that correct?

Either way I think your turbo is shot.

No and yes...

I have a FD with a T51R, but that is not the one i have problem with.

This one is a standard FD i just did buy from a friend.

So it has stock twin turbo and stock ecu aso....

Have you seen the video of the FD with a blown coolant seal? We are going to need a mod list...
