The other night i was giving the GTR full throttle and when i backed off it just stuck there bouncing off the limiter :O. My pedal was not stuck, this was the first thing i checked before shutting the engine off. When i restarted it was fine, it was going ok so i gave it 80% throttle still fine, so i tried full throttle again and it stuck again.

now i had a look under the bonnet, butterfly linkages move freely fine, however the very last butterfly near the firewall had a plug from the wiring loom rubbing against it, now i THINK that this was causing the issue because ive since moved it away and it may have fixed the problem but ive only given it full throttle a couple times since and it hasn't stuck.

the motor is built but the only part unknown is the oil pump, which makes me not wanna risk this problem happening again, any input or theory is welcome.

what i cant understand is when i shut the engine off and on again it was no longer stuck, if the electrical plug was wedged up against the butterfly jamming it from springing back i cant see how it would free up after turning the engine off and on again. for now im gonna spray up all the moving parts i can see without ripping things off with some CRC.

^^ It does? you got pre-ignition, torn engine mounts or something equally as stupid going on.

op.. seems you have fixed your own problem.

abit of exageration, but it will rock enough to loosen itself surely.

I hit the limiter all the time with my N1 pump!

But ye, it'll be that piece of loom by the sound of it.

I had it happen with a stray hose on my RB25 years ago, no idea how the hose even got loose/into where it did. Mysteries :)

      Welcome. This is not really true. We have a whole forum here just for the NA shitboxen. And they are not very different from the turbo shitboxen. Just weaker brakes and gearboxes, and no LSD, for the most part.

      I'm pretty sure it has an 040 in it @Duncan Also reading up, that turbo should top out at 250 as you first thought. It will be interesting to see how early it chokes due to the changes in the head too

      Yeah confirmed they are Nismo 555s, found the boxes in the spares with the factory injectors in. Yeah the AAC has been relocated to allow reuse of the factory brake booster line, and yes confirmed it has a 1 way valve in it. Unfortunately the one on the car is cracked, I'll need to replace it. Pretty sure I've got all the AAC plumbing correct in my previous post, but I am going to source some new fittings with 90o angles to help with the hose routing and also one really specific moulded shape for the AAC intake to cold start hose (will raid the back of our local repco when I get a chance and work out some combo that works) One of the big things I learned in the GTR is you need to be able to get your hands all around the bay when something goes wrong. I've done a bunch of re-routing now and it should be much more practical now. Also got the BOV mount re TIG-ed by the local engineering shop so that should be good to go now. Never got to the fuel pump because of some life stuff today, but will pull it to confirm it is suitable for 300rwkw when I get a chance

      Hello everyone, I am from Malta and have recently bought myself a fully stock 1992 Nissan Skyline GTS. It has the RB20DE engine and thus is NA. Unfortunately, not a lot of information can be found online related to the GTS, unlike the information for GTS-T and GTR variants. Apart of the Skyline, I also got a 1984 Porsche 924 2.0l NA and a 2002 Renault Clio 1.5DCi for everyday use. Excited to be apart of the community and perhaps get better information on cars such as the GTS.

      The fuel pump bracket just slides straight up.  Below is a pic I stole off a site. But basically put hand in for fuel pump, wiggle it all about a bit while pulling up.
