Can I use bolts instead of studs exhaust?

Super Moderator. I agree, the bolts in place of studs and nuts would be okay. Be sure to observe the torque specs for the bolts, i.e. to be the same as the nuts on the studs. You dont want an exhaust manifold to be too tight – it interferes with the manifold expanding at a different rate than the head.

Why is the exhaust flange connected to the cylinder head by studs rather than bolts?

Studs provide the ability to obtain much more accurate torque values because the studs don’t twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.

Why do exhaust bolts break?

This expansion and stretching of the manifold bolts over numerous duty cycles eventually causes too much tension on the bolt(s), stretching them beyond capacity and causing them to fail.

How tight should exhaust studs be?

Every vehicle has different levels of torque necessary to properly tighten its bolts. The standard is to use 20 to 30 foot-pounds of torque.

What do you put on exhaust studs?

If you are reusing exhaust manifold bolts (which we don’t recommend), apply a metal fortified anti-seize to your manifold bolts. If you’ve just removed the broken bolts and ready to complete the repair, chase the threads clean and use fresh OEM bolts for best results.

What do you need to know about tuning the Nissan RB30?

“All you need to know about tuning the Nissan RB30 engine!” The Nissan RB30 offer good returns when tuned and with the best modified modifications like remapping, turbo improvements and camshafts you will definitely improve your driving experience.

What is the best RB30 Turbo mod?

The best RB30 mod is a 6Boost manifold as they do a specific RB30 manifold which leaves the turbo roughly the same height as when RB26. Plan your options and then buy your modifications and set yourself a power target to avoid disappointment.

What is the difference between rb30s and RB30E?

The RB30S was found in some Middle Eastern R31 Skylines and in some Nissan Patrols. The RB30E was found in R31 Skylines and VL Commodores in Australia as well as in South African R31 Skylines (with 126 kW at 5,000 rpm and 260 Nm at 3,500 rpm)

Is there an RB30DETT engine?

There is also an ‘RB30DETT’ kit manufactured by OS Giken of Japan, which bolts an extension on top of the RB26 engine block, and fits liners, to give an 86 mm bore x 86 mm stroke.
