Hey Guys,

Just warning you im a newb to the 1JZ and turbo car world so please bare with me as I try to explain the problem im having.

I drive a 1991 Toyota Soarer with the 1JZ-GTE and when i got it back in october it drove beautiful and is quite fast and has been up until this passed week where im just not getting the power I used to.

Its hard to explain the issue but like I said I just dont have as much power but the turbos and everything seem to be fine through 1st and 2nd gear but once i get into 3rd and am steady at lets say 2500rpm ill press down on the gas and it will rev to 3900-4000rpm then drop down to 3000rpm and begin to pick up speed. Once I get up into 3500-4000rpm i can hear my turbos working. It seems to do this in 3rd, 4th and 5th, just no pick up at all. It will rev then drop back down like i was letting off the clutch or something.

boost leak? possibly only running on one turbo?


Any help would be great im scared this could be something big and costly.

Thanks for your time

Zack
