I have a 1987 turboII with a 60-1 turbonetics turbo with a evolution wastegate and fmic.I also have a turbonetics boost controller and for some reason i cant get this thing to make any real boost.I have the boost line coming directly from the turbo and have the vaccum lines ran per the turbonetics instructions.Please help

Disconnect the boost controller and run off the wastegate spring until you figure out how to use the controller. If an EBC isn't working, you hooked something up wrong or the settings aren't right.

What are you running for management? Any abnormal symptoms when you try to run it under boost? How much boost does it make?

diamondotg

it makes about 9 psi but u really have to rev it to get that like 6500 rpm or better

Pull the TID off and check the turbo by turning and wiggling the shaft. Is it stiff to turn? Does it move from side to side excessively?

Also, check/test for leaks in the intake piping and for exhaust leaks before the turbo.

i checked for leaks everything seems ok but there is a pretty good amount of shaft play is that a big problem?

Approximately how much play side to side or in/out?

diamondotg

if i had to give a mesurement maybe a little less than a half inch if that sounds right either way it has more play than i think it should have. The play is mostly side to side by the way

diamondotg

the turbo also makes kind of a shhhhh sound at idle

Half an inch?! That thing is dead. A little play would be about 1MM. At half an inch I would be expecting the wheels to hit the housings.

Half an inch is a hell of a lot of play.

hows the blades on the shaft if its bent more then usual then thats another way to confirm you got too much play.

Nothing to worry about now car cut off yesterday and when i went to restart all the ic lines were collapsing so i took a look in the turbo and the impeller fins were gone so now i guess the search is on for a new turbo

Well that's a very bad thing. If the fins broke off, they're probably now inside the engine. Your search may need to include a rebuild kit now.

It's a wonder you didn't hear it when they cam in contact with the engine.

With any luck, the fins are stuck in the intercooler.

going to get a new turbo think im going to get another 60mm what a.r exaust housing should i get?

Aaron Cake

iTrader: (1)

What are the exact specs of the turbo you are looking at? 60MM could mean anything.

diamondotg

buddy of mine has a 60-1 turbonetics with a .96ar exaust housing i think that big of a exaust housing isnt going to spool good on the street what do u think?

Aaron Cake

60-1 is a good choice, and that exhaust housing is a good one. You might go SLIGHTLY smaller if you drive primarily in the city, but don't worry about .91 being laggy.
