Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

The exhuast was farked when it made 330rwkw, 2.3inch front pipes into a 3inch catback than went down to 2.5inch in the cannon.

It's now got 3inch tuned length front pipes into a 3.5inch merge. Decat, and I'm just waiting on the 3.5inch tomei ti catback to turn up.

See how it all works out when the new system on bolted up. Than jez can do a full tune on it, cam gears, and all.

It's got type b pon cams.

Azza's made awesome power on the same setup I the same dyno.

His got a forged motor, but my motor is 160 across all 6 so it shouldn't b an issue.

C what happens

Not exactly the turbo's fault with the little 5's trying to blow out of that man.

So what's considered responsive with -5's? 1 bar at 3600 rpm?

from memory my rb2630 with -10s made 1bar @ 3krpm, I'd need to dig it up as I posted my results in each gear on gtr UK forum

Yea I no, the prob I had was I made up at 4inch system took it back to the dyno and only made 7kw more.

Im just saying -5 on something like your motor is crazy. It deserves a decent turbo. Gunna b awesome!!

You won't get that on a 2.6l unless it's fully loaded up :)

On the street it's around 4000-4200rpm in 3rd for a 2.6l if memory serves me correct

u are the first unhappy -5 customer I have heard...am I allowed to ask who is your tuner?

Add me to the list then for street/hill runs/motorkhana stuff the -5s are shithouse on a 2.6l

Cars was significantly faster with the smaller turbos coming on much faster in a on/off throttle scenario as -5s are lazy and need a stroker.

Interesting as I found my other gtr with -5s very responsive. That was a 2.6 as well.

What do u think is a good turbo for the application u refer to above?

Its not a loaded question- just like to hear your opinion.

Well given I've said many times over that I had -9s taken off to put the -5s on (so i can comment on both, unlike most)... Wouldn't say it's particularly difficult to come to such a conclusion :merli:

I've had GTSS, GTRS & -5's on a 2.6ltr (as well as -10s on a 26/30 which Paul has driven).

^ Absolutely you can comment on -9's back2back with -5's as you've had both...really is horses for courses though as I personally found GTSS's way too small (not sure how -9's compare to GTSS though)

I think it depends on the sort of driving you do. Guys that do the 'on/off/on' driving IE hillclimbs, skid pan work and track work will always favour the small stuff.

Steveo overlayed a 2.6 with SS's and my 2.8 with 5's and down low they were pretty much the same. Top end, well we know what happened.

2.6 with -5's is still lethargic, however peoples definitions of being lazy/lethargic/laggy are all different.

      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).
