Hey guys,

My names Josh and got my 1st 01 m35 yesterday. All is going good but i have this little niggle. It may be nothing but i have had it on full boost then when i let my foot off the accelerator, there is this like crunch sound/ feel under my foot. It doesn't do it all the time just every now and then. Any ideas guys. Just not hoping its much.

Get under the dash and check out the condition of the throttle cable, make sure its not slightly frayed and making that sound. Also WD40 the linkages too and see if that shuts them up :D

That'd be a good start ... eliminate them as being possible problems if anything.

good advice, except M35s dont have a throttle cable

they have a potentiometer attached to the pedal. apparently early V35s had problems where this would wear out.

but like Ruby said, stick your head under there and have a listen to where its coming from

keep an eye on it. if youre backing off the throttle from hard acceleration, it might be a worn or dry bush in the front suspension that is making it happen.

Alex, you like that huh? thats its actual name. its a variable resistor :ermm:

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok so will run the piping over that radiator and no plenum it is. Put that money towards a Haltech and see what suits. Any ideas something like an elite 2000 or 2500 right? My long term goal is 300kw e85 and manual swap and that’s a dream come true. For now will be 200kw and auto the stock rb25det neo intake isn’t too expensive with throttle body. If I was to have the port matching done, Would that be better than the stock de intake as the det has bigger holes plus has the spots for sensors etc? And suit more long term?  appreciate the advice?

      You understand AFR is not the only thing that contributes to it pinging yeah? Funnily, what the AFR gauge will tell you when it likely is pinging, is going to make you think things are really safe and good.

      Run the piping how we all have for decades. Also the duel runners with the +T setup dramatically helps it gets on boost quicker. Yes, chase huge power it'll become a problem, but you're a long way off when you're already saying an aftermarket ECU is out of the budget. You also say NisTune as it's simple, and then immediately say it'll be painful, meaning... It won't be simple. It will likely cost you a lot more stuffing around with a Nistune, than just putting a Haltech or similar in.

      I’ll order an afr gauge to keep an eye on it.  Then will get a haltech soon

      TD05 or maybe pulsar PSR2867r Gen 2?  id love a garret but it’s quite out the budget for now and I’m not chasing crazy power.    yeh fuel pump haven’t looked into but whatever works, kind of last on my list.    Nistune because it’s simple but Ik it’s a lot of pain especially as I’m auto +t with the whole seperate TCM etc still investigating that. Haltech id love but once budget tight for now atleast.    finally the reason I’m trying for a plenum instead of the stock intake is I already have a standard Intercooler mounted etc. so the ports are on both sides so trying to not have to go over the clutch fan radiator etc. trying to find a good deal return flow if I don’t than this will do for now I guess. btw any ideas with that, apparently some people have to cut blades to reduce it from hitting the Intercooler piping over the radiator ? Thanks
