Turbo to none Turbo??

[Sammy1970]

Hi ,Zeds

I bought a really good looker with a Turbo motor

set up with fuel injection. But no Turbo. Was planning to

put the turbo back on but because of the cost and problems

in finding parts. Have decided against. Was thinking of

keeping the Turbo motor as a lot of money was spent on it.

Can anyone give me the pros and cons of getting the com-

pression back down and running her as a L28.

any advice recieved would be great Thanks in advance!!! :stupid: :mad: :classic: :classic:

Hi Sammy1970,

First of all welcome. I think you will always find someone who can at least offer an opinion, some who can give you seriously good advice on lots of subjects. With turbo stuff thier are two or three absolute top notch forum members.

For your predicament, what is the package you have in place. Can you post pics. Are you running aftermarket or factory gear. would you be better off to grab an as is motor to get you running until you work out a plan of repair or build.

I think these are a few things that you would need to tell before anyone can sujest a fix.

Cheers

Steve

Yeah, welcome!

My first question is: where are you located?

All the Best! Sammy

Hi, Ben

I have uploaded some pictures of my Zed. Taken a few

of the engine block of the L28ET can you tell me anything

about it. Is it an orginal Turbo block? Or has it been built?

N42 9402A is what is stamped on the block I know

we do not have too many here in Aus as they only sold non

turbo here. Imports and custom made I quess is all we have.

I am planning to get her up and running with a few

basic mods. Looking for around 200hp. ANY IDEAS.

HAVE THOUGHT ABOUT TRIPPLE SU,S

EXSTRACTORS

HEAD WORK

Hi, sjcurtis

Unloaded pictures of my Zed and turbo engine just

wondering how long its takes for them to be approved and put into the Gallery?

I have an L26 in her but I want to put the L28 back when I lower the compression .

Do not have any Knowlegde on turbos and I want this toy to play with all myself. So its looks like its back to the SU setup. hoping I can use the stronger turbo block to do a few

minor mods on to get 200hp+ Exstractors, head and exhaust.

Correct my if I am wrong L24 151hp, L26 160hp and L28 175hp?

:ermm:

Any advice anyone??

Hi Sam,

I'm located in the southern suburbs. We should hook-up at some stage & have a look at your car.

I await the approval of your gallery sumissions & will have a close look at what you post there.

The N42 block is the 1st-generation L28 casting, with the F54 being the 2nd-generation block, used from around 1982 onwards.

I don't want to comment on your engine without seeing some shots

BUT, converting/building an L-turbo is a piece of cake!

I was of the beleif that the F54 block was the turbo block along with the P90 head.

The N42 block and head were the NA L28 combo.

Not that there is too much difference in the blocks mind you aside from the slight strengthening....

Firstly you would have to get the compression back up, as turbo engines generally have lower compression than non turbo motors. More importantly the type of head on the engine rather than the block would be usefull information.

Seriously. Get a turbo. :stupid:

Have you been for a drive in a turbo 6? You'll the power compared to a NA 6.

Z car garage has some info on turbo L28 engines and all the various z heads.

If your thinking of selling your turbo engine parts let me know I just blew a head gasket in my Z and thinking about a turbo swap or another engine setup.

Kinda, but it's a bit more murky than that.

The earliest 280ZXT's actually ran the N42 block & head (the automatic '81's)

When the BW T5 gearbox was sourced for the manual 280ZXT in '82 the F54/P90 combo was also available.

Late 280ZX's & Patrols here in Australia have F54 blocks & I believe that some of the patrols have P90 heads. I have no idea what car my P90 came from, but it was locally delivered.

With suitable chamber mods (or lower-comp pistons), a stock N42/N42 L28E can be force-fed without dramas up to around 300HP.

How does 170kW's @15psi on LPG sound from an internally stock L28?

(no it's not my car)

Sammy1970,

I think the best thing you can do is, if you are in Adelaide is go over and visit Ben, He knows a hell of a lot obout turbo and the 240Z. One afternoon could advance your cause by a whole heap.

All the information Ben is offering is on the money and yes as he stated F54/ P90 is an Australian Delivery Combo (NA) in the pre 88 Patrol. As to turbo combination you can get the power you are after with any L series 240/260/ 280 combo, the diffrence is for how long.

good Luck
