Got Over 400kw Atw?

[R31Nismoid]

Interesting stuff Ash, its amazing how much climate can effect things. What RPM does this happen for you with an Rb26?

Indeed usually up in the hills a bit as well is when it does it, so temp and probably pressure both factors.

It's just as turbos are starting to come off Vac so around 2000-2500rpm if i had to guess. Just as the boost gauge moves into positive is when it starts.

Only been up/out in that weather twice since I've had the car. Even @ Mt Baw Baw, when it was quite cool but not under 10deg even with altitude

Getting new ECU.

Autronic SM4

Vipec V66

or

Haltech platinum sport 2000

Looking for input before I ask my tuner what he wants to tune.

[bigmikespec]

Vipec V88

[Marko R1]

what is the variance in price and functionality between the v66 and v88?

i have the v44 & tbh, i never heard of the v66.

[zebra]

there is no v66

it is the nick name for the v44 plugin

[black bnr32]

there's a group buy for the haltech pro on gtrcanada

[SiR_RB]

What cat back exhausts are people running for these power levels?

Jap off the shelf items or custom made?

[Marko R1]

I ran a hks superdrager which was 3.5inch supporting 505awkw on 98 and now I run a veilside evolution full system which also is 3.5inch supporting 390kw on 98.

My mate bought the BSM GTR and surprisingly it runs a 3inch titanium system and that runs a 1000hp engine. I had a good look at it a few weeks and it is ultimate in gtr's what a weapon!

[NYTSKY]

Custom 4inch from turbo back.

[Piggaz]

Twin 3 inch from dumps back.

[SS8_Gohan]

all Midori, s/s front pipes and and Ti catback - Sard cat. not sure on the diametre though, and it would be listed in mm too.

as for ECU, Link G4 plugin - unless it's a really serious build, Ling G4 Xtreme, but obviously that's a wire-in job. I think there are some sort of harnesses floating around for the 26 though...

[WHITER33GTS-T]

4inch dump, 3.5inch back

Link G4 is popular with the tuners I speak to lately, and not much more expensive than what alot of people want for a second hand power fc!

Not when you factor in $600 ish Nismo AFM's ontop of your 7-800 for a second hand Power FC. It's really a no brainer. Yes the FC will do the job but the higher end ECU's like a Autornic SM4, Link/Vipec will do it much better.

[Marko R1]

When I had my power fc's in 2 different cars, I remember feeling a twitch every 10minutes which was very bizarre...maybe it was rebooting like a 'dos' system haha

[DVS JEZ]

The twitch is nornally the attessa relay clicking. Takes a bit of power (Volts) away

[Marko R1]

Fair enough, although, I don't get the same twitch with my vipec. Anyone know why this is the case?

[Nee-san]

Looks like a ViPEC unless my tuner says different.
