Rb25 Turbo Seals?

[grothie]

My car has started blowing blue smoke only on boost when I give it a little bit. The turbo makes a very odd whine hiss spool in vacuum and can hear it makin this whine once the car shuts off for a second. It also is quite laggy considering stock turbo. I took the front piping off and there was like a thin film of oil in it and the shaft play moves in and out about 1-2mm. I did a compression test and got 150, 150, 160, 140, 160, 160. Number 4 cylinder had gunk In the thread and it didn't tighten in fully. So compression is good. It also runs mint, apart from being a little laggy and sluggish.

Sounds like you have narrowed it all down. If you want an easy option get a replacement 2nd handy or better deal is to highflow it so that you have a new turbo with headroom

I blew rear seal on y turbo - it would blow blue smoke in the mornings (cold start) and occasionally if I jumped on heavy boost...

For the price of a high flowed turbo, getting a second hand one seems like an unnecessary gamble.

A proper highflow with increased power rating could cost upto $2K, depending on where you get it done... For something cheaper yet reliable (from what I've read), hypergear has some good highflows!

hyper gear high flow is a proper high flow!

Im in a similar boat to the OP. Im getting a standard hypergear high flow done as an alternative to buying a second hand neo turbo. It was only a few hundred more for a turbo you know the full history of, since its "new". I wont have it back into the car until a few weeks, so until then I have no opinion on how it functions.

Oh and dont forget to pull the intercooler out an rinse it out with some kerosene or similar....
