Re: What is the cast number of the 280ZX turbo hea

Casting numbers are either P90 or P90A. They will both bolt up to a '76 block. The P90A head has hydraulic lifters, the P90 has the more normal adjustable pivots.

Hi Z-Racer------------Although the turbo head is a direct bolt-up, you will be sacrificing some of your compression ratio if you use it on a '76 block. Unless you intend to modify your engine by adding a turbo, this swap will cost you significant performance loss.

Re: What is the cast number of the 280ZX turbo hea

thanx for answering all of my questions. i do intend to add a turbo so i want the lower compression. and if it is a direct bolt-up then i can use my old one to build an N/A head when i dont want turbo.
