Head Gasket for Bored out L20B

[haubstr]

I was searching for the head gasket for an L20B that has been bored out 40 over. I set the stock head gasket on it and it is to small. Are people using head gaskets from the Z20 or Z22's?

 

Thanks

0.040" is close to 1mm over, or 86mm bore. The Z22 gasket is 87mm and would work if you graft the very front of the old L gasket onto it and a small dab of rtv.

I think you can get a Nismo headgasket in that size too.

nismo is 88.5mm (and getting hard to locate)

wolf creek racing was the last place i found the had them

I also had a Nismo 88.5 for sale for $75 shipped

This is on the Wolf Creek Racing site:

 

4 Cylinder Competition Head Gasket - NOS Nissan Motorsports 11044-A7651 ($79 list)..L-series..........................$60

 

That is the 88.5mm head gasket. Is 88.5 too big for the 86mm bore?

 

Thanks

it SHOULD be fine(not racing it are you?). dont think you have much of a choice either :mellow:

So which head gasket is being used on the big bore LZ2.3 motors?

Probably the 89mm Z24 gasket.

This is my dad's truck so I don't think he will be racing. These are low compression pistons but he will be using a turbo setup that will put out around 5 PSI or so.

 

Thanks
