GT-R R35 Plenum Test Fitment on my VQ37HR

Spikuh

For the strut bar issue, I am curious if something like this can work well.



Was thinking keep the rear part of the triangular bar, cut off the center piece and use a bar like this to wrap around the front. Don't see why there wouldn't be room in front of the manifold for something like this.

As for strength compared to what we currently have, I won't even begin to guess. Most engineering I have ever done is on a phone app.

Room to do it this way would not be my concern. A U-shaped bar like that would not be as stiff as the stock 370z brace which runs straight across. That big U is much more flexible out of plane than a straight across brace. You give up more mechanical advantage by not going straight across and would signifficantly reduce the out of plane stiffness unless you increased the thickness of the new brace enough to add back enough flexural and torsional rigidity which is just more weight and less efficient.

yesterday I started the work on the strut bar issue. First of all we cut the horizontal connection as this will definitely never fit due to height.

The connection between strut tower and firewall is a no brainer - nothing changed there. Now we have to weld something strong enough to compensate for the missing direct link which runs in front of the plenum.

here is the link how it looks currently:

apart from that I have now driven about 2,000 miles with the new setup without any issues - no CEL, no bad behaviour, no idling issues, no nothing. From the current point of view you can simply change your stock plastic intake manifold to the GTR manifold and will have no issues, worries or need for ECU tuning.

Of course, ECU tuning is highly recommended to take full advantage of the new setup but I think its good news you can install it in your garage, drive the car when you need it daily and do the math whenever you have time to and drive the car to your tuner without worries.
