t3 saab turbo
i'm new to the forum and all but i have a question. grabbed a turbo off of a 84' Saab 900 today, looks to be in pretty decent shape, spins freely, minor shaft play. 2 things that i was wondering were...
1. there is a very small crack inside the exhaust housing, is that a huge deal?
2. if anyone happens to know the specs for the a/r and what the stock wastegate is set, i believe its adjusatble but just wondered. thanks in advance

NO. I ran that same exact turbo on my b16a for a while. Boost would drop off above 5k rmp because it cant flow enough for that engine. I know of a few other people that had the same problem. I swapped it out in favor of a larger t3t4 and the pressure loss went away. I had the boost controller set @10psi and boost woud drop off to about 4psi (@redline). Without the boost controller boost would go from 5.5psi down to about 4psi.....spools fast but has no top-end

Re: t3 saab turbo (coyote)
do the saab turbos come with the 3 bolt side exhaust wastegate swingvalve housing? i know at least one of the OE manufacturers uses this housing, but i can't remember which it is...
this is the piece i'm talking about:

too small..for your b16, go with a t3/t4 60 trim .63 exhaust side

Re: t3 saab turbo (TURBO18)
My buddies got a 95 Saab Turbo, I believe its a 900S. They come with a T25 I believe. What size is the Viggen turbo? how much bigger is it then the T25? Lastly is the Viggen turbo bigger or smaller then a 14B? My buddy wants to step up to a bigger turbo, whats his best bet? He has a chipped ecu for more boost ,fuel and spark, a full 3" exhaust and a K&N air filter.

i ran this same turbo in my b16a2 coupe, and it ran just fine...maybe u had problems elsewhere. for me it pullled all the way to the 8400rpm fuel cut

what was your exact set up with the saab turbo.
im also running the t3 saab turbo.before the intercooler and fule upgrades it really hauled ***,boosted till redline.once i added the intercooler and bigger injectors it dropped off a lot,now i peak boost at 10 psi at about 5k,then it drops off till i hit red like,from 10 down to about 7.its not tuned yet and im hoping to get rid off this problem.

im wondering if the intercooler is the problem then,before i put my intercooler on i could push 10 psi all the way till redline.

Same here once i added the intercooler boost would drop off. I know it wasn't the intercooler leaking because i had it modified (endtanks) and pressure tested. That turbo cant flow enough with a intercooler, i know of 3 others that had the same problem. My buddy didn't have an intercooler so he was fine for the short time he ran that turbo

Do you have an intercooler? Or did you?
I just read further down.....thats why yours ran fine, you had no intercooler, once you add an intercooler there is drastic pressure loss......(all 4 situations i've heard about involving this turbo/engine/ once intercooled)

thats odd, there should only be a 1-2psi pressure loss..i would say that your intercooler was damaged or leaking because I know people that have used them on intercooled b18's fine too (Tinker219)

Re: t3 saab turbo (MikeMAN)
I don't know everything about turbo systems, but it make sense that adding an intercooler will result in lower boost because:
1. The pressure drop in the pipes and IC.
2. The compressed air is cooler and now takes up less space.
I know a common misconception is that boost = hp. If the air's hot and needs a bunch of retard to keep from pre-igniting, that's not going to give much hp.

well i know for a fact my intercooler is fine,brand new,not only do i have all my pipes welded but i also have rubber couplings over every single weld and im using t bolts for clamps,so i know i have zero leeks,im using the same piping as when it was not intercooled also,my piping ran throught he front bumper so that when i got a intercooler i could just cut the pipes.like a i said before,once the intercooler was added i started having problems maintaning boost.
but i have not uned the car or messed with my cam gears and what not,i may be able to change things up to hold more boost.

we aren't arguing about there being a boost drop..thats pretty obvious if you have built turbocharged cars, but we are trying to figure out why the boost drop in his car vs. my car (the RATHER large one)
