Small T3 or WRX turbo--help me decide?
Hey fellas,
My DIY build is starting to come together now, and my goals are as follows:
-Keeping the car reliable.
-only around 170 HP, and it wouldn't be a big deal if I had a little less even.
-keeping the budget under $100 if possible
-quick spool, no need for a huge snail
Origionally I was planning on doing a T25 but I got a smokin' deal on a Begi early T3 manifold for $75 so that changed. So here is my question-- should I search for a used small T3 (where should i search, besides saab forums) and continue on with my build or should I use the nearly new free wrx turbo. I would much rather do the wrx turbo, because think the size is great and I have exhaust, which would lower my cost even more. The only problem is I'm not sure a flange could be welded in the orientation of the wrx turbo on the begi manifold. Attached is a picture of the manifold, and the wrx flange would need to face upwards....would a welder be able to make this happen?

Ford Probe. IHI VJ-11. Ubber fast spool on Miata and good for 14psi. Maybe more but probably not much. I ran one at 14. Also water cooled and CHEAP. Check ebay.

Looks like this one comes with boost control solinoid and coolent lines on it. $159+ship

Local junkyards! Call around. Look for the Probe units - US car parts seem to go for less than the same part for foreign cars RE Saab/ Volvo- but don't be afraid to ask for any T3.
On ebay there are several sellers that only sell salvage units. Good deals pop up from them once and a while. I got a brand new looking Saab for $160. Seriously, it looked like it might have had 5K on it. Something a little rusty on the outside would be less.

This one is OEM Saab... harder to index as the wastegate actuator is mounted on tabs on the compressor housing. It might work out fine on your manifold the way it mounts to it.

This is the one I'd recomend but isn't water cooled. ...and overpriced. But note how the wastegate attaches. That allows for 6 positions of the compressor outlet +/- a few degs either way if you tweak the wastegate rod a bit.

Remember also for the low cost of the Probe turbos you could get an adaptor plate. http://www.bmcrace.com used to have an IHI to T3 adaptor for the Ford Probe to put a T3 on the Probe. use it backwards.

this seems to fit the bill, I'm thinking about gong ahead and scooping it up. Any opinions on this little guy

looks to be just oil cooled, though
back to the other question i asked...does anyone think a good welder can weld on on upturned wrx flange for that (i have an uppipe)

This has been asked about before and someone had posted that the WRX turbo flows less CFM than the Greddy TD04. The only advantage I see over the TD04 is the WRX turbo is watercooled. I have both a WRX turbo and a Greddy TD04 and the TD04 even looks a little bigger than the WRX turbo. I haven't had them side by side yet because I have no reason to take the turbo out of either car. When that time comes I will post pics.
Also, huh... An upgrade it is...

i was sold a t25 manifold (though I was told it was a T3), so I had to trade my T3 turbocharger. No worries though, picked up an SR T25 in excellent condition and polished o2 dump for $80. The O2 will have to be sold to a nissan owner, since it wont work.
I just clocked the turbocharger tonight (thanks lazzer for the advice) and cleaned the CHRA. I'll keep the board posted on my build.
