RB20DE Running Rough After Plenum Change


Recommended Posts

Hey everyone, so I thought I'd change my intake plenum so it was a forward facing one,

and when I turned it on, I began to regret it..

It's idle is all over the shot wether it is cold or warm, it sounds and feels like a misfire, it smells rich, spits from the exhaust and the idle constantly hunts..

I've checked for vacuum leaks with Carby clean, yet to do with a vacuum gauge to double check, I've checked all plugs and set the gap to factory 1.1 mm I've remove each coil pack while it's running and all are sparking nicely,

Ive made sure the tps is set to 5 volts, I've checked the maf for correct voltage and it's within spec I've cleaned the AAC and the Cold start reg with no result..

Anyone have any ideas?! Please?

I will post a video below of the car running

    • Is there a particular model of the box that is recommended and where are you sourcing it from? This has me pretty interested as well for my 1JZ (currently with the standard A343 box). Also very interested to see how the turbolamik TCU goes. Is Tuned Performance assisting with this too? 
    • I've never used or seen that kit. project mu have a serious reputation in braking but there is a lot of information missing from that listing like type and style of dogbone, is the disc solid or full floating to the hats etc. It also mentions they run '1 synchronised pad per piston' which sounds overly complex solution to a non-problem to me. Also no information on price or availability of replacement pads or rotor rings If I was looking for something that serious I'd go AP racing or perhaps Brembo as they have plenty of users and good availability, but in any case something like Just Jap ATTKD are proven and less than half the price (assuming that listing is USD)
    • does anyone have any experience with the project mu forged sports 4-piston kit for the GTRs? it's a front brake bolt-on kit, 355mm x 32mm forged aluminum 41mm piston 4 pads / caliper from my experience with the brand in the past, they make pretty solid stuff, so i figured this would be a nice upgrade for the R33. anyone here have experience with these? the site search didn't really yield any results, just posts about brake pads, mostly. cheers!
    • I vaguely remember there was something about it when I did my plates/subframe bushes but it might have just been a forum post I read. 
    • Now installed, fun times as the GKtech manual makes no mention of modifying the subframe brackets/brace plates. Needed to lop off the hump as the GKtech subframe bushes are flat and don't have an indent. Heaps of swearing later, it's in 🥳
