i have a 1982 280zx.that was given 2 me from my dad.he did nothing 2 it but let it sit so i got it.i just got a few questions about the 280zx.how do i tell if the engine is a L28e or L28et?and in what ways can i increase the performance on this car.

i heard that getting more air in and out is always a way to go.i want 2 know what r some other ways to go?i also heard about adding a turbocharger or a supercharger.

someone give me some info on which way to go

thanks,

If its an ET it would have a turbo hanging off the exhaust manifold. Pretty hard to miss.

And a valve cover that says in rather large letters.....TURBO.

Before you start planning any sort of upgrade (turbo or supercharger) you must go through EVERYTHING THAT GOES BAD like vacuum lines, filters, fuel, plugs, electrical connections, connections in general, clean your injectors, clean your gas tank, check your fuses,...

Once you get it running as it should, then start considering upgrades.

Or, you could just pull the engine and replace it with a built engine, but for that you will find more info at hybridz.com

Welcome to the site, and congratulations on the free zx!

Here's an overhead photo of my engine bay. If you have a turbo engine, you will notice several obvious differences (namely the turbo unit itself and the different valve cover).

You were asking how to tell what engine you have . The block should have cast on the side F-54. This tells you it is a ZX block the head has markings , P-79 which is a NA head , P-90 or 90a are turbo heads. The 90a has hydraulic lifters. If it is a NA engine it has flat to pistons the Turbo has dished pistons.

thanks 4 ALL THE INFO
