I could not find anything from them on ebay but I found their website but they charge 2-3 times what other sellers on ebay charge for a turbo. Did your friend use the wastegates from SS Autochrome? Just curious if he did and if they worked well because they are inexpensive.

On this info I checked my riv turbine and sure enough the bolt pattern does not mate to the standard buick elbow. They are close enough that unless you put the elbow on it you won't be able to tell. All the time I've had the riv turbo I never checked LOL. One thing I can tell you is that the riv...

The chart is of my own making. It's cut and pasted from a spread sheet I made to try to inventory the mess of turbos I have. I had some turbos already then a friend recently gave me a whole bunch more making about 16 total mixed between early buicks & ford 2.3's with 2 diesel t4's for good...

So does this mean an 84-85 Riv turbo is essentially the same as an 86-87 GN?

Here is a chart with a listing of some of the different turbos I have and their specs. You may find it interesting to note that the compressor wheels on the early carb turbos are actually the same size as the 84-85 buicks & 85-86 fords. It's just that some of the early ones had small housings...

Definitely .60 A/R and definitely 84-85. In fact one is from a Riv. Even came with the funky Riv exhaust elbow on it. And it's not a fluke because I have picked up 3 of them over the years and they're all the same. The centers, including the wheels, are identical to my 85-86 t-bird turbos. The...

For this project I am more willing to part with my money for something of good quality. I just don't want to spend it needlessly. It's not like my budget wagon project we were discussing in another thread where I am trying to use whatever I have where possible. I have too much money tied up in...

I'll have to measure the shaft. I hadn't thought about that. I have 2 TO4B wheels & housings but only one is big enough. So the other wheel I'll have to buy and have the housing machined to match. The measurements on the wheel I have already are 2.19 minor & 2.75 major which matches a V-trim...

Hmmmm...where to start....I have a lot of experience working on cars and hot rods but not with turbos. That's why I'm here. To take advantage of you guys who have done it and can prevent me from making some of the same mistakes. The 84-85 compressor is not that small. It's .60 A/R same as the...

How come the hybrid 301 turbo is so expensive to get assembled? Since the bearings seemed good I figured new seals and a balance for the new turbine. And which center section is better to use for it? The one from the 301 or the 84-85?

Being an engineer I have to smack myself occsionally for overthinking. My friends call me on it all the time LOL. So then those exhaust turbines from my 84-85 should be just fine matched with the T4 compressors on my big block if they can handle a 3.8. They'll only be seeing 3.3 liters on the...

Well, I wasn't going to destroy the 301 unit. I was just going to make flanges with stubs to connect tubes to and swap the turbine. But as you said that stupid 90 degree foot would make things goofy. Trading for your 86-87 is a definite possibility. Only thing is I honestly feel this 301 unit is...

What's that extra part that extends past the alternator? Is that for a/c? Just curious. My 79 is non a/c and the 84 has that cast aluminum monstrocity on the pass side.

Oh, and if anyone of you guys ever sees a Grand Am front fascia for sale let me know! That would look awesome on this wagon.

Actually the engine I picked up to turbo is an 84 and it came with all the accessories, including a/c. So I have the same ps/air pump bracket you have Adam. I took another look at the engine on the stand and the only part of the bracket that will interfere with the belt going on the middle...

Attached is a couple pics of the current 79 set up. You can see that the ps pump is way too high. But check out the nice upper adjustment bracket for the alternator that I can easily weld, or even possibly bolt, to the 84 PS pump bracket to give me adjustment. Then just weld a tube on the bottom...

I had a chance to look under the hood of my wagon and I am definitely going to use the 84 brackets and mount the alternator where Adam did. On the 79, because it has no a/c and no air pump, the PS pump is up too high and leaves no room for the alternator on the driver side. One question Adam...

I was thinking along those same lines Adam. I like it! Looks like a good solution to me. Only difference is I was thinking of adapting the stock N/A alternator arm from my 79 instead of the angle iron like you used and using the 79 v-belts. I can also use the 84 alternator, PS pump & bracket. I...

My thoughts exactly, but right now I am trying to do this with what I have. I have two other projects eating funds. This is my budget project. A $9.99 ebay 84 N/A 3.8 is the starting point. I will probably start with just one of the 84-85 turbos I have and see how it goes with an eye on...

Anybody ever run 86-87 turbo headers on an engine with a distributor? I am trying to figure how to mount the alternator since the turbo goes in the original alternator location and the distributor is where the 86-87 alternator mount is.
