I dropped my R34 GTR off at Red R Racing yesterday morning for some bolt on upgrades at the hands of DirtGarage (Paul) and co.

Ive had a few people show interest in my planned upgrades so I decided to start up a thread for those interested. Thread will include plenty of pics and final results with a full mod list at the end to accompany dyno results.

A few of the parts going in, more to arrive - see below

Cheers

320AWKW but we will see how it goes. Dont want anything too crazy, bottom end is stock.

As for response loss on RPM, time will tell. Hopefully not much though, will post full results so will be able to compare to my stock turbos.

maybe i am wrong but aren't your chosen turbos HKS 2530s equivalent, but GT-SS which have less lag make 320 awkw easily..

in fact there are a second hand pair in classifieds that made exactly that?

Bakes, Matt was having trouble keeping his mind on the job...every now and then he would stand back and admire your car. He's been around plenty of tough GTR's and to see him drooling over your car was a laugh.

Have been over and over GTSS vs -5. Not going over it again. I did my research, I wanted -5s, I bought them. Please keep turbo selection out of my thread.

I am excited to see the results of this, great stuff.

Quick question, with regard to the wideband, why did you not go with the Innovate Motorsports WB which is reccommended to be used with the Vipec ECU's? Geniune question, I am not just being a d**k.

PS: in comparing dyno runs details of AFR and ignition advance would be good to get more of a direct comparison.

      Stock rb25det neo questions

      By Wazmond · Posted

      Apologies, while id like to put the MAF as close to the TB and relocate the recirc, this may be too much work. Will most likely end up just putting it on the original AFM spot ( onto/next to the airbox ).  Was going through nistune, found a pretty nifty doc on this. Nistune MAF Notes. Also, i was looking through the bay, and there seems to be a tube/line connected from the A/C to the intercooler piping ( Between the smic and the recirc), what does this do as the crossover fmic piping doesnt have any connection? plumbing? not sure what you call it but the nipple thing ahah.  Also, been reading up more about crossover fmic in regards to the legality of having the hole drilled for the piping, this would most likely need to be engineered right?

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By joshuaho96 · Posted

      My advice is if you need a big build done do it in Japan. The yen rate is so favorable and there are shops that can be genuinely trusted and not micromanaged/carefully monitored every step of the way. Garage Yoshida is obviously my preferred option but they're so busy these days and all interaction with new customers has to be mediated through BBL/Toprank now.

      I haven't....but a poorly made one would terrify me. Surely a good second hand one is the go, as they don't work hard and no-one wants to keep one after they are finished with it A big consideration would be the weight of the shell you are putting on it....is it a fully dressed chassis or just the body

      Not stock. All remade. Mostly looks stock because the pipes run to and from the standard holes in the inner guard to get to the return flow FMIC. I'm not sure which question you're trying to ask, because it seems like "stock position" vs "stock position".

      Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
