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.

      That looks good, but I think you're going to need much beefier side skirts now.

      new 1.5 LSD issues/concerns

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
