Considering twin turbo setup on '85
One of my 'vettes is an '85 4+3 (it's not a Z51). Honestly I'm wanting to do something fun with it. I have seen the pictures of the '87 Callaway twin turbo setup and I love it. Looking for thoughts about what would be involved to pursue the twin turbo setup for my car... not sure what all I would be getting into.
If the parts to do this are difficult to locate and costly, then should I consider an LSx swap instead ?

regardless, the Lsx swap will likely be less-expensive. It's also a heavily supported engine (i.e. tons of aftermarket support with tons of quality products).
If you choose to go FI, have you considered a supercharger? If so, Greg at blowerworks.net is the go-to guy.

The parts are essentially non-existent. You're going to have to fabricate your own parts unless you want to spend HUGE bucks on the true Callaway stuff.

A buddy I race with has an 89 Aerobody. He just bought a set of Callaway headers for his twin turbo off ebay for $2K for a spare. The turbos are no longer available as well as most other parts unless you want to buy a complete Callaway and swap them over (doesn't make sense, huh). There are other ways to make horsepower with your Corvette.

After looking at that rear bumper it likes they just took a c5 bumper cut it in half and attached it the the lower c4 bumper. I like it.
That procharger looks awesome and the price isnt bad.

Thanks for the reply's....but, now it looks like my twin turbo thread has been hi-jacked and changed to a C5 rear bumper thread...

Calllaway did a full motor build/blueprint not just boost
rather see one large turbo than 2.
Try turbonetics/turbo city in simi valley ca. And they will get you going with the right one. Stay away. From those quick and dirty kits on ebay.
Would be nice tosee you doit. Even 4-6 lbs isnt too hard on things and wil give a real nice power increase but a stronger bottom end is a plus.

if you do do a turbo or s/c setup keep in mind that the cooling systems in our cars tends to be on the weak side,and a big air to air innercooler mounted in front of the a/c condenser and radiator may cause over heating problems.

Chris has run a single-turbo Lt4 to nearly 1000rwhp (his threads can be found in the FI forums).
The last I heard he was swapping over to an Ls-x and keeping it boosted.
