Headbolts/studs- Upgrade or not?

[B0oStEr]

I'm building an rb25de engine using an rb26 crank and rods with forged pistons.

I'm going to use arp rod bolts and had intended to replace the headbolts with arp studs.

I spoke to my engine builder today.

Apparently arp don't make rb25 11mm headstuds but he can drill and tap the block for rb26 12mm headstuds.

He wants an extra $300 or so to do this plus the studs, just when I was looking to shave a few dollars off the cost of this project.

Does anyone else make upgrade headbolts or studs for the rb25?

How dodgy would it be to reuse the stock bolts and save $600?

Thanks for that.

I think his words were his supplier couldn't supply them.

I also tracked them down on the arp site.

Part no. 202 4301

I'll see if I can find them cheaper than UAS.

let us know if you do find them cheaper

I was ordering parts today for my RB25 rebuild

When I ordered ARP rodbolts and priced the headstuds the guy reckoned I'd be mad not to do the mainstuds as well.

Keeping in mind I'm on a tight budget I was wondering at what power level you would have trouble reusing the stock main bolts or head bolts for that matter?

What kind of mods are you doing to the car?

What turbo do you plan on running?

What boost do you plan on running?

What RPM do you take the car to?

For now I'll just be running my hks gt2530 for about 220 kw.

It should make that power at about 16-18psi

If I upgrade it will be to a larger low mount and cams for about 300kw

I set the limit at 7500rpm
