My car is a 2000 sir and here is what I have:
-drag turbo kit
-thermal 3" exaust
-440 injectors
-hondata stage 2b
-hondata intake gasket
-3 bar map upgrade
-JE pistons(9:1 and 20 over)
-EAGLE rods
-clutch master stage 5 clutch
-clutch master lightweight flywheel
-all necessary gages(boost, oil, egt,air fuel,...)
-fpr
-str block guard
-msd blaster 3 coil
-msd ignition wires
-msd distributer cap

Now I want to know how much whp can my block take without arp head stud? Keep in mind that I dynoed 274,9whp at 9psi on a stock bottom end so can you say major boost creep from the delta gate....
And what would you do next for speed mods and reliability?
Thanks
Karl

I'm not sure about the head studs, but have you thought about upgrading to a tial wastegate? Also, you're probable pushing those 440's pretty hard at that power. What kind of duty cycles are you seeing?
Sounds like a badass car .

ARP head studs will not necessarily make your block stronger. It isn't uncommon to actually lift the head slightly when running over 24lbs of boost on stock head bolts. This lifting can cause the headgasket to blow and other nasty stuff can occur. So common sense tells you the headstuds will keep the head on the block without stretching like stock studs do. I see you have a block guard already, but if you really want to make your block stronger then i recommend resleeving it with either Darton or Golden Eagles. If you want to keep stock sleeves and boost even more, then i would recommend upgrading to a hondata 4b and adding more fuel upgrades, but i recommend resleeving to be on the safe side. Yes there are some guys out there putting down 400+hp on a stock block, but i guarantee you there are a LOT more guys out there with a blown engine because they thought they could be another 400hp honda with a stock block. Tuning is essential...

I'm asking that question because I will tune hondata on the dyno and I want to know until what whp I can tune it without blowing anything....I can't afford a tial wastegate right now and I want to run about 280 whp everyday(9,5psi). So is the head stud a must for that kind of whp or I can be reliable without one?

OEM honda rods will withstand the 9.5psi just fine, but it is always good to replace them with something better. Just because you use ARP headstuds will not make your motor bullet proof, the headstuds are not the weakest link... your block is.
