I can supply Nismo composite gaskets or Kameari Metal gaskets.. :)

I would recommend to make your own copper head gasket.Or have one cut out. That way you get the thickness you want and quality too.
I had one made for about $80

No more gasket problems. Too Easy

I use the genuine Nismo gasket which has a wire ring under the fire ring for extra 'bite'. (Note some have this some don't). It's on my 13:1 C/R A series race engine - no problems. Expensive but they don't blow. I'd suggest they'd be good for turbo too.

ask bige he has them

so where can you get the nismo or tomei product in ozor do you have to get it from japan?

An A15 I had o-ringed. From memory the ring is 1 long piece covering 2 cylinders making a figure 8.
I will try and dig up a better pic.

nismo metal head gasket. multiple thicknesses up to 2.0mm im sure.
The goods in my opinion

I've used monotorque head gaskets for years, they have been known to fail for time to time, but in my turbo motors i just use a repco head gasket with a shim plate, haven't had any problems so far, standard head bolts is all that you need, even with a shimm plate.

I strongly recommend use a good quality head gasket, saves alot of heart ache when all the hard work that goes into a turbo systems fails only due to a cheaper part( or any part for that matter) It is true what they say................ YOU GET WHAT PAY FOR!!!

i got told by my engine builder that the a series had too close bores to o ring anyway.

genuine gasket all the way i reckon

An engine reconditioner I deal with said that O-ringing is old school, and with modern head gaskets being a lot cleverer than in days of old, it wasn't something he'd recommend.
