Headstuds

Posted

Has anybody used or heard of Black Market Performances head studs? They’re about $150 less and a ARP set and the same tensile strength. Was curious if anybody had used them

    I looked at a few other brands of studs that were cheaper than ARP's...can't remember the names of them.  But when I researched them myself I found several complaints of snapping while being torqued.

    Headstuds are kinda like insurance against a blown head gasket if you're gonna run higher boost pressures.  Headstuds are needed when running boost pressures of 45-50 lbs or more.  The stock headbolts

    Also used for longevity. Like in my case I don't want to do head gaskets every 300k miles. The tinsel strength of the ARP 425 should keep the head from curling on the end over time. Where normal head

Most here go for the 62/68/12... My 60/60/12 HX35/40 hybrid I grabbed it for the fact I didn't want to lose my exhaust brake which most aftermarket turbos you end up losing the exhaust brake (turbo mounted) then moving to in-pipe exhaust brake.

 

A lot also depends on where you want your best rpm range to be. 

 

60/60/12 will do best at lower rpms, such as towing in higher gears. The 62/68/12 will do better at higher rpms, such as racing, or more "spirited" driving.

60 60 12 sounds like me. I dont like to go much over 2200rpm

    Hx40 has a weaker turbine shaft. This why the HX35/40 hybrid was made. The stronger HX35 turbine is used and then the HX40 compressor.

     

    Or...

     

    Some mod the HE351 turbo. Basically the same specs.

    I think a 62/65/12 would be best for your goals.  It will spool like a stock turbo and give plenty of air for towing and has room for you to grow if you decide you want more in the future.
