Ld28 block with l28 turbo head??

[260z.76]

I was reading the other day about a guy who had done a rd30 block woth a turbo rb26 head and was running 32psi boost or something

 

Has anyone ever thort of trying this with a L series engine?

[260z.76]

Heres a link i could find about the rb

Just interested in the hole thing and was wondering if could be done

I have recently picked up a complete LD28, normally we bin everything but the crank, however I will keep the block this time to study it in more detail

[260z.76]

Awesome!!

 

Please let me know we could see new hp gains from this

 

And the L series go to new levels

 

Thanks!

LD28 is pretty much the same as L28 only it is 15mm taller in the stroke, isn't it?

[260z.76]

Yea but deisels are built stronger cause it take high comp ratio

 

So maiting with petrol head would alow more boost with the stronger block

I had a bare block for a little while.

Bore spacing is the same.

Casting seems to be identical.

The only visual difference I could see was the deck height.

So how's that stronger?

[260z.76]

Not sure the

Rd28 with a rb26 head the block was stronger

 

The strokes and bores are a bit different in the 2 as well

 

Ld

Bore 84.5

Stroke 83

 

L

Bore 86

Stroke 79

I am sure if they where that much better race engine builders wod be using them years ago.

It would be interesting if a petrol head fits on, would be an easy way to get some longer rods in there while keeping "stock" l28 pistons

First the LD block is lots heaver and has a small bore and wont take a large bore  even if you try to sleeve it , i have try ed

it runs bigger head bolts witch is cool for the Rb 26 but not for the L head . and you need to mod the water ways a bit as well ,

So don't bother there is better ways to do it

cool that is the stuff we didn't know and why I have kept the block for once. But it might go to the scrap too now.

Been done before.

that sounds scary!!

you can not get a 90 mm bore with this block even with sleeves the bore is 84 standard , well you can but there is no steel holding the sleeves and would cost a shed lode to do for no advantage
