Why do you want a metal head gasket? The stock head gasket can handle at least 160HP (Nissan genuine). The factory A-series metal gaskets were extra thin to increase compression.

Or were you thinking about a custom thickness Copper gasket?


It's just because i want to eliminate some risks. And where could i get this custom thickness copper gasket?
Thanks!

id roll with the standard gasket myself. its an easy job to replace one on an A series, usually takes just a couple of hours. if you run into problems down the line is when you could opt for the more expensive one. just my opinion.

Okay, I can try to roll with a new gasket then, and see what's going to happen! Good opinion :) Thanks mate

Hehe, It's nasty! Floors are great, dash is cracked, front seats are good. Everything else is missing.

Made some calculations today.
If my coupe weights around 840kg and it has power of 117Kw
It's going to have ~7.2Kg/Kw. And Finnish law says that turbo charger is same as engine swap. And when doing engine swap, weight/power ration must not go under 7.
So it's getting close! Haha, I'm trying to get that 140-160hp out of this little beast. More pictures uploading on weekend!

And found contactless ignition for 4-cylinder engine. And send a ordering message for missing instrument panel. And what else....
Just going to clean up the whole engine. Oh, the crankshaft has to be little oversized, because bearings were terrible! But getting new ones probably next week.
New steel parts cut for rusty areas. And some measuring need to be done with horizontal intake (110mm aprox) and with new dellortos, and still need to fit pressure chamber there, going to be tight!

Hope you guys are interested in with this project, send me some ideas to make this system better!
Oh and I'm taking volvo 740 radiator to this engine, should keep the temps lower! And thinking of getting another fan to the motor, bigger and with more wings=more airflow, right?

i bet its raining volvo parts over there.

is the head in the picture the one you plan on using? the fact it has water ports is going to limit the size of your intakes. earlier a motors didnt have them. if you are going for a turbod engine it might be something you want to keep in mind

Haha, it's just because i have one 740 that is left over and i'm using brake system and rear axel from it.

Sorry didn't catch that. Are you thinking that 740 radiator has too big waterports or?

no. the cylinder head on the a15 motor you have has water ports along the manifold side. if i were planning sidedrafts w/ a turbo, id want to port some bigger intakes. you cant really port the head you have because youll run into the water ports.

Ah, i see. I have thought this, and ended up to keep it normal sized. And yes, they are pretty close, and there might be not enough room to have them bigger without breaking anything. We'll see whats going to happen, but it was a good point :)

the h72 castings are dime a dozen here in the states, and you could cut them as much as you like. if you dont mind shipping, i have a bare h72 that im willing to give you for the price of shipping. its just taking up space as it is.

Both Tomei, and kameri make metal head gaskets for a15's. Neither are cheap... both have different thicknesses avail.


FWIW, Nismo also makes one, costs $75 last one I bought.

It's your car, just don't ruin it.

 

It's also not my money, so i'll suggest the most expensive option.

The metal gaskets are to increase compression. Is that what you want?


The copper gaskets are very thick, designed to lower compression for forced induction engines. About $100-$200 and can be reused.

Yeah, i thought it would be better for turbo engine. And with bigger pressures, it would add more stuff to chamber where it detonates.

And i know it's not cheap :/ but for now I'm going with original, since it can take that 160hp.
