Re: Teaser alert.....
The pan definitely needs to come off since it's a 2WD. And I want to see what the crank looks like since it was supposedly is a shorter stroke.
Valve covers, sure they're easy to R&R.
I just don't want to start tearing into it, taking things off & then have a bunch of parts sitting around & then something gets lost. Or, it'll turn into one of those "while you're in there" deals where I'll never be done with changing something I don't like. I'd like to keep it "as is" and only make changes due to a mechanical failure.
Since it has everything except for a muffler, I was thinking of one of these to test it on. That is if I can find room in my already overloaded garage. :lol:
I see a couple of leaky spots.

Yesterday while I ws poking around, I found a nice bracket they made that does double duty. It bolts to the block, supports the turbo & protects the lower portion of the serpentine belt, around the crank pulley, from the heat of the turbo.
All of the exhaust tubing is stainless, while the flanges are steel.
I'm going to pull the turbo off today so I can remove the compressor & exhaust housings, take some measurements & inspect for obvious wear or damage.

I sent an email a few minutes ago to the contact info on the website & here is what I got back:
Good afternoon Rick.
Thank you for your interest in SVI!
Yes, we did a 4.3L single & twin T/C - CAC feasibility study (Y Car & "other" targets) for GM.
What specifically would you like to know?
How did you find us?

Re: Teaser alert.....
I will feel worthless until I can post pics of the actual car.
Working on it.
Also,I think the Race Rock Cafe story is pure BS.

Re: Teaser alert.....
taken from an article on Zr1netregistry.com
The story of the Corvette ZR1 goes back to a program that got underway in late-1982. With engineering work on the soon-to-be-introduced '84 'Vette complete, Chevrolet's Corvette Development Group had begun work on a high performance derivative known internally as "The 400 horsepower Corvette". The first attempt at this was a twin-turbocharged 4.3-liter 90° V6 powered unit of which as many as 20 prototype "mules" may have been built. However, the Corvette Group found this approach totally unacceptable due to the V6-90's inherent nasty vibration problems and underhood packaging. One engineer told us that the induction system length from the turbocharger compressor exit, through the charge air cooler to the engine was seven feet and "-although the cars had lots of power, turbo lag was so bad, you could time it with a Big Ben alarm clock." A car such as that must have been dreadful to drive. With all these negatives, the turbo V6-90 idea was discarded.

Re: Teaser alert.....
I removed the DP from the exhaust housing & I could see why they said it had terrible lag. The exhaust turbine has very little restriction.
I'll try to get a good pic of it so you can see. I'd pull the CHRA out for a good pic, but some of the bolts are rusted so I've been spraying PB Blast to try and get them free without snapping them off.

Re: Teaser alert.....
After continual application of PB Blast overnight & then some heat this morning I was able to remove the CHRA from the exhaust housing.
It's a very interesting wastegate setup. The outer vanes are controlled by the wastegate arm. They all open & close simultaneously to control turbine speed.
Notice how small & little the pitch is on the turbine.

Re: Teaser alert.....
That is different, that is the same way that a Francis Reaction Turbine works in a hydroelectric powerplant. In that case you would have a highflow of water with low and medium head pressure. 99% of the time they are super reliable, but can you picture one of the links breaking on the outer vanes ? When you use the engine get a different turbo for it. The most that I seen go bad was 7 and the noise that it made is something you don't forget. Do you have any pictures of the other side showing the connection of all the outer vanes with the wastegate arm ? TIA

Re: Teaser alert.....
The bolts that hold the vane plate on are pretty gunked up as well. They're gonna need some more PB Blast & heat to get them free.
When I removed it & tried the actuator about 3 of the vanes weren't moving. They had popped out of whatever makes them move. I rotated them & eventually they seated and began moving in unison with the others.

Re: Teaser alert.....
Well I thought that the vanes were attached to the backing plate & when I turned it over havoc ensued. :rotf:
Stuff started falling off & rolling around. Luckily I found everything.
Here is what the backside of the vane plate looks like.
The doglegs mesh with the outer notched ring & then one of the three elongated holes engages with the actuator arm.
