One of my freinds freinds was selling a ray jay turbo kit bolt on for a non EFI z....how does this work? and do you think its worth buying it for 300 for the whole kit

Studebakers used a through the turbo setup...nothing new there, but that type of setup means seriously keeping up with your state of tune! If it is complete and in useable good shape as it sits, $300 is a good price.

yeah he just said you need to keep doing alot of adjusting

from what i've heard, SUs and turbo are not compatible, since the SUs require a certain amount of vacuum to work properly

For what it is worth, Corvairs used a carburator on their turbo motor for years. It worked fine

Hi Will:

What Studebakers used a turbo? I remember in the mid 50's and early 60's they used a belt driven supercharger, that pressurized the carb.. (Golden Hawk and Avanti)...

I still think the 63 Avanti was one of the best designs of the decade, and wouldn't mind having one today.

I think the 62 Olds Jet-Fire was the first tubo from GM, followed by the 63 Corvair Spyders.

FWIW,

ya, i recall the good ol' turbo corvairs. but they used a standard doundraught carbie.

lookin at maybe turboing DGVs or DCOEs?

You are looking at pretty old technology there, I might suggest that it would be a real challange to set up right and keep right.

There is a brief article on draw through turbo conversions in the H.P. BOOKS "How to modify Datsun 510, 610, 240Z" [which in turn refers to the Hugh MacInnes book How to select and install Turbochargers"].

The turbo used the downdraught Hitachi carb from the L4 series engines.

You would need to seriously consider the lack of mixture control and ignition timing control with this system.

In this day of off the shelf aftermarket EFI systems and decent sized intercoolers, I think you would be very disappointed in the olde school setup:ermm:

Your choice, of course.

Back in the day - - - I had seen about four of these systems installed. Crown sold a kit for both the 240-Z's and the later fuel injected 280Z's.

A local Z mechanic, replaced the single S.U. used in the system with a side draft Weber 40 DCOE. He built his own adaptor plates - to mount the Weber in place of the S.U.

As I recall these systems recommended no more than 8lbs of boosts... but several of the guys ran 10lbs for years.... O-Ringing the head was also recommended by the kit manufacturers at the time (mid-70's).

I agree with Nissanman that the old school kits do not really compare with running an L28ET with the factory or newer engine management systems, ect. Nonetheless, for $300.00 if the entire kit is there it could be some really cheap fun.... as long as you don't over-use it and blow an engine.

I think all SU carbie turbos use a draw through type arrangement for that very reason.

Carl,

Sorry I missed your post,

The studbaker crowd has been using them for years-though they did not come from the (expletive deleted) that way!

I have been getting a turbo news letter, 21st Centuray Turbos for years(it had been around far longer than I have been a subscriber), and it started out for the Studebaker crowd(I absolutley agree with you on the Avanti!). Interestingly, it is also available in book form published by a gentleman named **** Datson from Sarasota, FL.

Carl must have been referring to the Paxton supercharger that was an abailable (expletive deleted) option.
