hi guys i need some help i drive a R32 gts-t with the following mods:

mapped to 1 bar with apexi power fc on 95 ron fuel

3 inch straight through exhaust with decat

apexi induction kit

greddy spec 2 boost controller

uprated turbo elbow

gtr front mount intercooler with 3 inch piping

RB25 turbo

GTR fuel pump

oil cooler

my problem is that my car seems slower now than it was when i got it when i got it it was boosting 0.8 with an induction kit and exhaust and it really pushed me back to the seat it doesnt have that anymore. when i got it mapped on the rolling road it was hitting 245 bhp at the wheels, which i think is a good figure considering its mapped on rubbish 95 ron fuel. now if anyone can help me with a few question i have i will be very grateful.

1. will mapping it on shell optimax make a big difference? bhp wise how much are we talking on estimate?

2. should i use 2.5 inch intercooler piping instead of 3inch? what difference will that make?

3. is my standard bov ok to be running on 1bar?

4. what are the advantages and disadvantages if i get my intercooler pipes welded instead of using the plastic hoses?

any other help or advise you want to give feel free. thank you

thanks guys

1. yes, it should. You could possibly gain up to 10rwkw, maybe more.

2. Shouldn't matter that much, the smaller pipe might help throttle response. But I doubt it.

3. yeap, should be fine, if not, get a GTR BOV to replace it. Don't use a Vent to atmosphere, your car will run like crap.

4. None. If there are no leaks, then none at all.

Have you put it on the dyno to see if it has actually lost power?

I have 300rwkw, and it feels pretty average after about 3 months of use. You get used to it and think your car is slowing down.

But definately get it tuned to better fuel. Shouldn't take any longer than about 1 hour on the dyno.

Without going back and putting it on the same dyno (to find out if your making 245hp still) its hard to tell.

If indeed you find its making the same power, in the same fashion... easiest thing is dive a corolla for 2 weeks and it'll feel fast again :ninja:

      R34 GT-T cycling ABS pump

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
