It seems the t3 from the ford thunderbirds works well with the 2.8.
Also, the older 'kit' systems came with an IHI RHB5 turbo that you can find on a lot of of the older import cars.
I'm trying out an IHI VF30 off a WRX STi. I have no idea how well it will work with the motor, but I happen to have it and so we'll see. Once I finish rebuilding the 3400, I can dyno it, and know for sure.
If you need any minor help with your homebrew, shoot me a message....

If you are going through the trouble of building a turbo system the last thing you want to deal with after putting the whole thing together is a faulty turbo. It is best to purchase a new or reconditioned model unless you really know what you are buying. There are many used turbos for sale and you are relying on the buyer to provide information on the turbo condtion which can very subjective. For example, "little shaft play" and then when you get the turbo shipped to you there is "a lot of shaft play". And, not only that oil and coolant fitting are frozen, and the thing is rusted to death. Yes, I am speaking from experience.
well I think a junkyard turbo should need be rebuilt regardless. If your lucky, and you happen to find a decent one, sobeit, but I would plan on a rebuild otherwise. you can get a rebuild kit for about 75 bucks, and its just good insurance in my opinion.
I got lucky, the turbo I picked up has about 8k miles on it, clean as a whistle....

If you're going for a stock 2.8 or 3.1 I would say the 2.3 Ford turbo or a Subaru unit should be OK. I'm building a 3.4 TDC and I'm using an '87 Buick Grand National turbo (Garett T3). There's a huge fanatical GN, Turbo Regal, and GNX following so there's a large aftermarket available for it, plus most of the GN guys think their stock turbo is too small so they replace them with bigger units, making stock GN units relatively easy to find. You could also try the turbo from a '90 3.1 Turbo Grand Prix. They're about $850.00 for a reman at AutoZone without a core. With a core it's $165.00 less.
Basically small turbos are good for low end with less lag, larger turbos are good for mid to higher rpms with some lag. It's all in how you drive the thing. What was the question??
