Webers on blow through turbo thoughts

[IdahoKidd]

Hi guys, I found locally a fellow that has a set of webers and a blow through turbo manifold with turbo for sale. He says the manifold and turbo came off a 79 Skyline. Neither the turbo nor the webers have seen use for 10 years but of course he is convinced they are "good". I am posting a couple of pictures and am hoping some one can give me a sense of what this is worth and if it is worth fooling with.

Many thanks!

Leaonard,

My basic understanding of blow through set ups from a friend who was going down this route, is the carbs need to be "sealed" specially for this. The Mikuni (in the last picture) and the Dellorto 45m carb (on the Lotus Esprit turbo [i think] can stand the pressure as they (like) the Dellorto have an "O" ring on the spindle. I don't think the Webers came in a form like this, unless they have been machined to allow the likes of "O" rings on the spindles. Though stand to be corrected.

There is a bit on Hybridz on this.

I've heard good and bad stories aobut these setups. Personally I'm interested in doing one so if you decide you do not want to mess with it please let me know as I may be interested in buying the turbo related parts (I've already got the carbs).

Some say it's not worth the time/money/trouble and that more power can be had for less time/money/trouble by just using a turbo ZX engine setup. Actually a good number of people feel this way.

Then there are the others like myself who are not working on a daily driver and want something fun, different, and period correct (i.e. no FI). So for us it's not about the time nor trouble, it's just kinda cool, fun, and different.

I'm sure you will get some more comments on this. You should also spend a little time searching here and on hybridz about the triple carb turbo setups, you'll find plenty to read.

Thanks for the info. I hadn't considered that. The guy wants a $1000 for what is pictured as well as the turbo, that isn't pictured. What carbs would have been on the skyline as pictured in the complete setup? I can't tell for a fact that the mikuni's would even bolt up to the turbo manifold. I was hoping someone had some first hand info that would tell me to buy it, run from it, buy it and sell it to them, etc. They seem like hard parts to find (not so much the carbs, but the manifold and so on)

For a $1000.00 you would be buying nothing but a money pit that would result stress and strain. If you haven't got a lot of experience with projects like this - run from it.

I am going to take your advice Carl. I already have a 77 with a turbo set up from an 83 not quite finished (shoulder surgery). A buddy is considering the manifold and turbo to set up with 6 flat slides from street bikes. I don't have that kind of patience.
