GTR Running troubles

Please can anyone help? I own a 97 Skyline GTR that is running on 5 cylinders most of the time. I have taken the car to Nissan and they have replaced the plugs and number two cylinder coil pack, and the problem is still there. Nissan can’t find the problem and they can’t find anyone that will look at the car either. I think it has something to do with the electronics but not sure. It runs like crap nearly all the time now, but if I put it under a little boost while its cold it runs normal till it warms up then runs crap again. If anyone has any ideas on how to help it would be greatly appreciated. Cheers

Rotate the *new* coil pack and see if the missing cylinder moves. If it does they've replaced the wrong one.

Alternatively pull the plugs and see which is fouled.

Could be any number of things - plugs incorrectly gapped, igniter (if R33 have them vs R34 with built in igniter into coil), dodgy coil-to-igniter loom...

      Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.

      Anyone know this frontpipe?

      Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.

      So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.

      I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
