I'm collecting parts for a b20vtec with a gsr head build I want to uses gsr head bolts because I won't be boosting it and won't need arp bolt. I don't know what brand would be the best, let me know what brands have a good reputation and makes quality stock gsr head bolts. Also it will have about a 10.5:1 compression ratio, what would be the best spark plugs and to use?

Well since OEM head bolts are out of production, ARP is your best bet.

Plus ARP are re-usable.

For something that important, just pul the trigger for the right part.

Do it right the 1st time and then you wont have to look back

While it wouldn't be a bad idea to go with ARP wouldn't it be overkill. I probably will go with ARP but if I don't have to I won't.

what are your other choices?

j_the_guy

I'll be pulling the head from a jump yard so the actual stock bolts, I'll probably just go with arp just to be safe.

Oh I didn't think about lifting the head. Yeah I'm going to get ARP rod bolds and rev it to 8400, don't worry I have the valvetrain for it. Too bad they don't make b20 sleeves so I can rev it to 10,000; I'll have to get a 84mm sleeved b18.

so, what you wanted to hear was 'you can re-use the old head bolts' right? cuz a mod just told you that the oem headbolts were discontinued,..

The OEM bolts are actually still available. The part number is 90006-P72-003 and is still active.


Lifting the head only comes from increased cylinder pressures. Increased engine RPM does not increase cylinder pressure, so upgraded cylinder head fasteners would not be necessary for this issue. More HP and more boost create increased cylinder pressures, and thus would require cylinder head fasteners that can handle these increased pressures. This discussion assumes that ignition timing is appropriate... aggressive ignition advance will cause dangerous cylinder pressure spikes even in NA applications that can lift the head and blow a head gasket, although piston damage usually comes first. In this case however, the issue isn't that the head bolt wasn't strong enough...

If you knew the history of a set of head bolts... and they had only been torqued once... twice... maybe even three times previously... and hadn't been OVER-TORQUED... there is no reason to think that they couldn't be re-used. There is no way to know how a set from the salvage yard has been treated... after all, the vehicle IS in a junk yard.

OP, if you do choose to purchase a set of upgraded head studs, the ARP product is NOT the best choice out there. Although ARP does make a lot of great products, the Honda/Acura DOHC head bolt applications are not one of them. The A1 Technologies product, which has been private labeled by AEBS, Golden Eagle, etc. is a vastly superior product and I would recommend that you acquire a set of them instead.

It wasn't meant to be a correction White_EG1... more like information that is presented to be educational. I meant no disrespect.

any idea where i can find some A1 technologies studs? and dont say google either because im literally finding nothing about them except for diesel applications, and golden eagle only sells ARP head studs now.

j_the_guy

I want to know where I can find the a1 technologies head studs too for the best price as long as they aren't stupid expensive if they are better than arp I will buy then.

after a l little searching ive come to the conclusion that they no longer exist, the only A1 technologies ive found are for diesels and they are $700 and up so even if they did make honda studs it would probably be outrageous

been gone for 3 or 4 days, whats the verdict? A1 sauce or ARP derp.

JRCivic1

Motorvations Motorsports has them in stock. Give them a call. They are a bit more expensive than the ARP bolts... but worth it.

Arp makes great studs. If you need more than a standard ARP, then get the L19s. If youre not going turbo, then in reality OEM bolts are fine. IIRC, Fel-pro sells stock replacement bolts at very reasonable price.

j_the_guy

I'm not trying to cheap out if I don't need ARP because I won't be boosting it I don't need them. Does anyone know the quality of DNJ head bolts or where to find the better oem replacement bolts?
