Nice, that car looks BAD ***, what year? pretty solid looking setup too, Kinda funny tho in that pic of the turbo it looks like you need to plate over the hole in the mani for the external wastegate.

i think my turbo is no good... for some reason its just oozing oil out of the center section on the exhaust side im going to pull it and make sure all of the bolts are tight. i hooked up my pressure regulator and everything and now i have to wait til it cools down so i can pull the turbo.

why would it be leaking from the center section on the exhaust side? does oil actually get into the exhaust housing?


the car is an '85 corolla gts. i built a block off plate for the wastegate after that pic, you can kinda see it in another.

THere'S nothing wrong with using a used turbocharger for a HMT project but in order to avoid having to install it TWICE, it's always recommended to have it profesionaly rebuilt first.

oil is leaking out the turbine side because that'S the place were all t3 turbos start to leak when they go bad. There'S no "SEAL" to prevent that from happenning, just a piston ring around the shaft and on a USED turbo with shaft play and/or clogged with carbon residues, that piston ring quickly wears out, causing the notorious turbine-end oil leak that is so common to all t3 turbos.

if your compressor is a 0.42 a/r, it may actually be just a 40 or 45 trim and those are good for less than 200HP so if you're trying to make more than that with your turbo, it will keep failing on you. IMO, you must make sure you have at least 50 or 60 trim compressor if it's for a performance application. THe 0.48 a/r stage 1 turbine is acceptable for sure.

well i purchased the turbo as "rebuilt". i took it apart and the oil seal (ring) was scored and so is the surrounding surface. i took a very very fine wire brush on my dremel and cleaned out the material that was in there and took a good ring i had from another turbo and fit it in there... the deformation of the metal is oh so slight, but it still catches the ring slightly so im going to assume its just going to coumpound the problem if i put it back together like that, and not fix itself. there is absolutely no play in the shaft also. i did take a look at my return line and for some reason i couldnt find any oil... as in oil went into the turbo but didnt leave from the return, this is the first time this happened. could it be crankcase pressure? the fitting is at the same level as the factory return for the oil cooler so its not backing up.

i looked at your site, blaast, and i may pick up a t3 from you... do you carry the .060 oil restrictors as well? my goal for this engine is 200rwhp, which is about ~240 crank. spool up doesnt have to be at 2500rpm as i rev to 7500... so id like to size it with a little room for more power in the future.

Ya man im going through the same thing, when i get into boost my car smokes like its on fire lol sum lady actually came up to me at a light as was like "Ur F8ckin car is on fire!!!!!" lol man it was funny as hell

turbo4age

hahaha i would see the smoke coming up as i slowed down and just shut the car off. i only have about 6 inches of downpipe so the smoke would come out of the hood.

its gonna be all better in a week though, i just bought a new turbo with everything else ive needed from blaast. i cant wait to get it in and running.

okay folks... my turbo will be here on friday and im looking for a coolant source for the turbo. is there a certain amount of coolant that has to pass through? or does it just need to be present and circulating? i took out all of my heater lines and the two lines to the throttle body when i put this engine in the car. is there any way to tap into the radiator hoses? or can i tap into the block? if i tapped into the block where would i end up dumping the coolant to?

any and all help is appriciated.

sirclay

Dont tap into it, just put it inline with the "circut" Like this:

coolant line turbo coolant line
=========( O )========

Not like this:

tee coolant line turbo coolant line tee
I==========( O )==========T
=========================================


If that makes any sence lol

BLAAST

Sirclay is right, you just stretch one existing water hose to pass it in the turbo.

Well i went to the track lastnight... my best time stock NA was 16.6 at 85mph and lastnight i went 14.8 at 95 with a horrible 2.3 60ft. i dynoed it the night before and it made 150rwhp and 156rwt at a rich 11 to 1 afr and only 6psi.

boost controller is in the mail... i have plenty of fuel left so ill turn up the boost and see what she will do.
