ARP Head Stud Kit for 1993-98 Supra
Product Description
Part # ARP 203-4205
We can not express enough how much we recommend you purchase ARP products when working on your 2JZ head.
First, your stock bolts that come with your Supra are made to stretch. They are technically called TTY (Torque To Yield) bolts. Toyota (and all manufacturers) put TTY bolts in a head when manufacturing the car because they are the cheapest bolts available, and when you are using millions of bolts in a year even 10 cents a bolt adds up. Once these bolts are installed the first time, they stretch because they are made to. Once they are in your car for years they become rather worn out. When you take them out of your head they are stretched and should be thrown away (same with flywheel bolts). Never re-use the original bolts in your head. If you do you'll be buying another head gasket in a matter of weeks.
Second, ARP bolts and studs are rated by their tensile strength in PSI. Simply put, this is the amount of pressure that would be required in order for ARP hardware to sheer or snap. Although we can not rate a TTY bolt, we can estimate that their tensile strength is around 60,000 to 80,000 psi. All ARP hardware for the Supra is rated at an incredible 190,000 psi, about 3 times the strength of Toyota TTY bolts. All ARP hardware is made from a heat treated 8740 steel alloy. MSRP $256.06 Your Price $161.00
ARP Head Stud Kit for 1993-98 Supra - L19 Exotic Part # ARP 203-4205 L19 Cheap? Not exactly. The best? No doubt! That is why we stock them on our shelf! You do not have to wait, we have these ready to go unlike our competitors!
Until now the only way to hold your head down when you are trying to make big power with the 2JZ has been to bore out your head and install 1/2" special order ARP head studs. We now have a quicker and easier solution for you!
L19 material offered by ARP is the most expensive and strongest material offered in a stud. MVP has ordered STOCK size ARP studs in the L19 material! These will provide over 1000psi MORE clamping force over standard 1/2" studs and they are a direct swap! If you already have a built motor you could even swap these out one by one and not have to redo the top part of the motor!
This material is special order and VERY expensive. When you consider doing 1/2" studs you have to machine the head, machine the block, redo the head gasket, buy 1/2" studs, washers, nuts, and they are a pain to install. And you also have to transport an entire engine somewhere to do it. This solution is much more cost effective and feasibly work better than 1/2" studs while saving you time and work.
There are a few high HP Supras already running these studs with no issues so they are proven to work. ARP has also done all the calculations and assure us that these studs do offer MORE clamping force than the standard 1/2" studs.
These studs make building a very high horsepower engine significantly easier. You can build a new motor and put these in to start or if you already have a built motor on standard ARP 7/16 studs you can pull them out one by one and swap them in for these.
