Head Studs - Toyota Yaris Forums

Can anyone get a part number from toyo or point me in the right direction for a set.

I can find anything online for 1NZFE head studs.

Mabey PM Aras and see if there is any updates ?

sleey0 · 10-07-2010, 11:08 PM

Thanks but Garm confirmed ARP never made them.

I am just looking for the darn Toyota OEM part number at this point.

Some company in Spain makes them but I have no idea who or what the name of the company is (or quality for that matter).

So, Head Stud OEM part numbers anyone?

TIA

Ok check the pic. Is the "17159 BOLT, STUD (FOR MANIFOLD TO CYLINDER HEAD)
90126‑08026 1NZFE..NCP91; INTAKE SIDE 2 $3.38
90126‑08037 1NZFE..NCP91; EXHAUST SIDE 2 $5.35

What I need? I am not sure if this is the right head stud. 2 for cool side and 2 for hot?

cali yaris · 10-08-2010, 12:33 AM

I think there are 10 total.

Call the toyota parts dept. Their 110.00 for the set. They're yield 90 deg. So you need a new set everytime you remove them.

This is not a hard part to find.....Are you serious.

Also if your gonna take the whole motor down then you may as well buy the complete seal and head bolts kit for the entire motor. I've bought 3 of them from Toyota.

Just call toyota get the kit and be done.

You do not warrant a custom head stud kit.

Heres how this plays out:

Golden Eagle sleved block = at my cost 1,150.00 (thats just sleeving)
CNC block for custom head studs= 350.00
Toga main bearing race set= 80.00
Polish crank= 110.00

total unassembled = 1,690.00

Now since Golden Eagle does not assemble this motor we now have to do this:

Get the block noched to clear Crower rods = What ever price someone wants to charge you. My cost = free did it on a Bridgeport machine at the shop.

File fit rings for pistons

Assemble all parts Rods/ Pistons crank check for clearences ( you may want to use blue dyecom for this, it will visually let you know if your not clearing)

Once completely satisfied ensure torque spec are meet.

Oh yeah, rods = 800.00
Arias pistons = 800.00 for another 1,600.00

You are now at 3,200.00 without the charges of the above mentioned stuff. This is because you don't know how long it will take to assemble or get proper fitment. So for GP we will say 1,600.00 which will be about average

now your at 4,800.00 and haven't even gotten to the head or assembly of it or timming of the motor.

This is all the things you need to account for. Almost 5G's and not even close yet.

Got it.

What if I just want to change rods and not pistons? To not fuck with the C:R - just to beef up the weakest link?

Is that sound reasoniing for 12psi?

sleey0 · 10-08-2010, 10:40 AM

Well toyota keeps telling me there are only 2 head studs I don't know what the heck is gone on

cali yaris · 10-08-2010, 10:44 AM

^ Did you look at the technical manual (with diagram) that Thomas publishes on both this site and MI? A visual would help you.

Also, think about the head, sitting on the motor. It's pretty obvious that two bolts are not going to hold it on securely.

Nexus1155 · 10-08-2010, 10:47 AM

The picture you listed does not have head bolts themselves. Those are just for intake and exhaust manis.

Ajusas sells headbolts, I do not know if they are reusable. About half way down the page.

sleey0 · 10-08-2010, 02:25 PM

"Should I get a new gasket too? Toyo wants $55.

Is there any better options?

sleey0 · 10-08-2010, 04:00 PM

Just ordered the 10 studs with washers!

Now, they quoted me $45 for the gasket.

Is there a better option, or is a gasket a gasket? lol

So did the AJUSA head bolts hold up? I have a set for a Toyota, 1.8 L , 2001. The head gasket supplied was an eristic. No good reports from me on the eristic head gasket. It is leaking like a sive after only 30 minutes max run time.

Quote:

I just wanted to clarify, the head bolts from AJUSA seem to just fine.

The Eristic Head Gasket is the suspected failure point. I have heard many others complain about the Eristic Head Gasket too.

I plan on using the AJUSA head bolts and a FELPRO Head Gasket this time.

Thats why i posted the previous link, apparently some have failures

sleey0 · 10-08-2010, 08:10 PM

Thank you but it doesn't matter now because I got the head studs and washers and gasket from toyota.

Change the pistons also. The ringlands are weak.

If you don't want to go through the hassle of building your own block, we offer one now. http://www.ptuning.com/html/Item-Des...l&ModelDesc=xA
