Typical R34 Problems Gotten More Advanced

Hey guys.

So, I've got a 2001 S2 ER34 Skyline, It's N/A. I bought the car and drove it around for about two months with no issues at all, then I started to get the check engine light come on, the car would lose all power and run on probably 4-5 cylinders, As usual, you could turn the car off and on and the check engine light would go away, but would then come on a day later or 5 mins later, completely random.

After reading up on this being a usual problem, I took all the throttle body off and found there was cheap ebay coilpacks in there. I removed them and chucked in a mates Stagea coilpacks, OEM ones. Put it all back together and drove it around for a day with the check engine light NOT coming on. Next day, boom.. check engine light. BUT, It wasn't losing any power/ running rough. Did the same thing, turn the car off and on and the light went away. It got more consistent. So I took the coilpacks out, took the plugs out, cleaned the plugs and checked the power going into the coilpack plugs, All 12volts. I checked they were all sparking consistently and the same. All good. I chucked everything back on and everytime I start the car, the check engine light will stay on, It drives fine, no misfire, no rough running.

Today I took it into a local auto elec and had a diagnostics run on it, Code 21. He cleared it, started the car up again and boom, code is back. Car is still running fine..

Does anyone have any idea as to what it could be... I'm stumped atm.

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.

      Hell, I know that much. So far I just put it off as "part of the deal".
