Turbo'd Slant 6 apparently has no turbo??

[finnman1]

Finally got the slant to run right with the 1bbl. had to take the turbo/ 4bbl off. got it timed, ran great. put the 4bbl n turbo back on. hit the starter, VROOOM! Fired right up!! couldnt believe it. systems check, everything still good. give it gas to 3200RPM, no turbo whine, no whistle, no nada. boost gauge shows 20deg of healthy vacuum, 18 when i step on it which is normal. heaven forbid we go into boost.
i've got all my vacuum/boost lines hooked up correctly. i had the boost gauge run off the intake (P.B. line) so it should've shown vacuum till it got more gas, then turbo took over and should've crept into boost. didn't know if any of you turbo guys knew what the deal was. it uses a buick draw-thru carb base fed into the turbo so it's a draw-thru. TII garrett off a 87 newyorker.
the propeller was nice and firm, barely any play, spun freely, excellent condition before installation. wonder if carbon and crap in the engine from 4 years of sitting fried my turbo?? it almost seems like it's siezed up and the fuel/air is bypassing the propeller thru one of the blades. i have no freakin idea. mechanically, the exhaust should spin the turbine propeller no matter what if it's not siezed up. however ive never heard of such an instance. any ideas?

Do you see the compressor spinning?

So whats the highest reading youve seen on the boost guage?
Its not under load so it might have trouble spooling. But this is a slant six motor and the turbo is off a 4banger so im assuming thats not the problem.
Does it have the stock internal wastegate? Is the actuator rod on the flapper post? Im guessing the flapper is doing just that, flapping in the exhaust...

Take it for a drive or two foot it.

well, before installation, the compressor side spun freely, and i also hooked up an air compressor hose to the wastegate line and it moved the wastegate rod right away (before installation), so the outside part seems to be working. and there seems to be a little oil coming out of the seam on the exhaust turbine housing where the waste exhaust pipe (pipe going to muffler) (no muffler) is. right where that bolts to the main exhaust housing. i hope you know what im talking about. it seems the exhaust housing has 2 parts. one for the blade where the exhaust goes in, and the side where the exhaust exits, right where these two join, theres a mineute bit of oil seeping out. that shouldn't stop it from spinning though right? supposedly the wastegate was rebuilt on the turbo....

I second that. Turbo will not show boost unless you load it..

[finnman1]

alright, i'll try that tonight. guess ill try to finagle something into 4bbl linkage. ill get back ya all.

would be nice just to check if its spinning when the engine is running. True it shouldnt do anything out of gear at 3000 rpms.

[finnman1]

i concur, i thought a buddy had a 90's turbo car and it would spool well reving it in neutral. however this is a different setup.
about that gasket. if there even is one between the two exh housing parts; anybody know where i can find one? i don't want to buy a whole gasket set, but i will if all else fails. i do have a "create-a-gasket" material somewhere, but it's like cheap thin cardboard.

One Garrett TII turbo is wayyy small for a 225ci /6

[turbovanman]

If your talking turbo to manifold, nope, no gasket. You can just use axle grease. When you get it warm, it cotterizes and seals.

[greendog]

you should realy be running twins on there

[finnman1]

i know, i know...the garrett is a little small, but i found a site where a guy was running a mitsu and got 16's in the quarter. here's the site if youre interested.

[speedyshelby16]

If he running a mitsu way are all the pictures of a t1 log car turbo?

[Turbofreak]

find a turbo off a Buick 3.8L turbo 86-87 preferrably....

as long as you are going blow through...
