73ZCAR Posted January 20, 2007 Share Posted January 20, 2007 CARTO410, Use a stock turbo gasket from Nissan if you are not going to boost any more. If you are, just buy the metal gasket from these guys. http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=CP&Category_Code=s30_nismo_headgasketL28 Mike.

Tony D Posted January 22, 2007 Share Posted January 22, 2007 Similar here, stock Nissan Gasket, 21psi, with daily running at 17-18psi no problems in probably close to 60K miles. Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted January 22, 2007 Share Posted January 22, 2007 i have a spare HKS 2mm metal headgasket i could sell ya. Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 23, 2007 Share Posted January 23, 2007 As a side note - use at least the turbo head bolts (ARP studs ideally), and follow the proper torquing sequence when torquing the head down. I usually go around the head two or three times with increasing torques - say 45 lb-ft the first time, then 55, then 65 (the turbo head bolts get 65 lb-ft). Also, re-torque the head after running two or three heat cycles on the engine. Let the engine cool overnight, then back each bolt off ~ 1/8 to 1/4 turn, then retorque in sequence, one at a time. I usually do this two or three times on a new gasket, just to make sure the gasket hasn't compressed and caused a loss of clamping force.

zguy36 Posted January 24, 2007 Share Posted January 24, 2007 I don't think there is a difference between turbo head bolts and non-turbo head bolts. At least they have the same part numbers at the dealer. Quote Link to comment Share on other sites More sharing options...
PETEW Posted January 24, 2007 Share Posted January 24, 2007 You can go to Top End Performance. They are selling both 1mm and 2mm steal headgaskets for $185. They are cometic gaskets I believe.

At least they have the same part numbers at the dealer. Hmmm... perhaps they just stock the turbo bolts for all applications now - there used to be a difference.

Doug71zt Posted January 29, 2007 Share Posted January 29, 2007 Turbo head bolts have a recessed ring around the hex. They are different than the regular bolts - the std bolts will twist off if you torque them to the turbo specs. Doug Quote Link to comment Share on other sites More sharing options...

CART0410 Posted January 29, 2007 Author Share Posted January 29, 2007 Ok Lots of good feedback thanks.. I have decided to go with an HKS gasket and ARP bolts. I called HKS today only to find out they are not making that gasket anymore. I also called Cometic they have never made a Head gasket for the L28 Motor. So does anyone know where to get a NEW HKS head gasket for a 1982 Turbo car??? Also while I had an HKS tech. on the phone I asked about reusing there metal gasket. He said people do but they do not condone or recommend it..... Quote Link to comment Share on other sites More sharing options...

He said people do but they do not condone or recommend it..... They have to say this only to save their asses in case some one tries to blame them for "taking their word" on it and suing them if a problem occurs. Plenty of people have reused a metal headgasket from HKS with no problems to report. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted January 30, 2007 Share Posted January 30, 2007 Just make sure to spray it with copper spray if you re-use the metal gasket. Quote Link to comment Share on other sites More sharing options...

TONY C Posted January 31, 2007 Share Posted January 31, 2007 i have 3 of these gaskets. 2 of them i am still using and 1 of those has been used 4 times that i know of. 3 of those times by me. just soak it in laquer thinner or acetone. clean it the best you can and they're good. i have had a few guys pm me . so to let you all know. the 1 i am willing to part with has been used for less than 100 miles and was only removed fer a 2mm for boost reasons. it is perfect. but not new. unless an engine grenaded i don't think they can be hurt. might be able to get a new 1 from nissan motorsports phone # 888 833 3225. last time i got 1. the 1 i will part with. 1mm. $150 +tax cause i am in state. i don't have the part # handy but you can do a search or just call they know what it is. tc. oh yeah, if i was an hks rep and wanted to sell a gasket i would tell you not to reuse it too. just buy another 1. my sales are low this month anyway.

TONY C Posted January 31, 2007 Share Posted January 31, 2007 just got off the phone with motorsports. they have a couple 2mm gaskets left. no 1 mm. i asked if they are going to get more and the answer was probably not. but who knows. cost is $150 and $10 shipping. tax if you live in tennessee. part # 11044-91mm2 for the 2mm. if your not running 15lb's or more than the 2mm is not for you. hope this helps someone. tc.

PETEW Posted February 1, 2007 Share Posted February 1, 2007 I am new to this so I figured I would ask this question. I see a lot of guys running the 2mm head gasket vs 1mm. Is there a reason for this? My machinist said he would prefer that we use the 1mm to keep the head as close to the block as possible to help with heat quench. Are there clearance issues, that I am missing? Quote Link to comment Share on other sites More sharing options...
