John, what are you you running in your gtr anyway? You inspired me to go twin efr a few years ago but I never really know your whole story

Slightly off topic but some pics from last night's clean. Excuse the shit pics, crap phone and a couple of beers too many!

Hi all!   I've not really been active on this forum for some time and although I lurk in to read bits and pieces of interest I don't really think of this as a forum I'm part of but I once was and I di

Very nice, that wing is massive, what is it and where did you get it if you don't mind me asking :)

It's a custom job by Andrew at Custom Carbon Creations or CCC. Designed by Scott Beaton from Aero Design, the guy behind the WTAC rules.

I've recently cut it down 100mm each side also, was huge back then!

Did you get the proshonk stuff sorted?

Love the green wheels

Not yet, car is resting until next year now. I've ordered some replacement LCA's and just need to make new hats and dogbones to better space the rotor.

Thanks, matches the green roll cage also (can't really see that in the pics)

No twin scroll? :(

Im thinking about going to a 7163 and getting rid of my oil leaking FP green on my evo as FR have a lowmount kit out/coming out. I believe Geoff has 1 on his evo now.. Id love to hear how thats going and what fitment is like from Geoff. I wouldn't wanna sacrifice any response over the green even though i know its a 6lb bigger turbo..

Do it! The EFR7163 will blow the FP green out of the water....

All though it is a lot of money for not much more top end (if any)... Might be better to look at a twin scroll EFR7670??

Haha im pretty confident that the EFR will smoke the HTA. But i dont wanna sacrifice ANY response. Im not after top end at all Alex its the midrange & response i seek :) id also like to stay lowmount.

To be honest id be happy with 330-350kw max but i just want the most responsive setup with most area under the curve i can. The green starts moving in lower gears at around 3700 that'd be as laggy as id like.. As you know Point to point there isn't much faster than an evo.. I want to keep to that recipe as much as possible with my car as it suits the style of driving i enjoy most. :)

How about you grab a 7163 or a 7064 and tell me if it's nicer than your GTX3071 :P Then maybe i'll chuck one on my 34...

I've seen a couple of tests where the 6258 doesn't really outspool the 6758 despite the smaller wheel and falling off much sooner. IIRC one comparison was on the ART silvia and the other was a Perrin test.

Given how fast the 6758 spools it doesnt matter too much, but still, anyone know what the deal is?

I don't know for sure what the story is there, I have seen ones where the 6258 comes on quicker but either way I do know and have before seen dyno plots which don't represent what happens in the real world - at least in terms of response. Might investigate but either way I see no reason in going smaller than a 6758 as a single turbo on something aftermarket

Is anyone running an EFR8374 with 0.92 A/R T4 twin scroll (internal wastegate) on an RB25/26?

What sort of power could be made with this turbo, WMI setup and other required supporting mods? I have not been able to find much info about actual results with this turbo.

Cheers

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂

      Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?

      Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.

      34 de+t conversion using s2 stagea automatic transmission, engine harness and ecu

      By albyz34gt · Posted

      Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys

      Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
