Yeah i agree i just had a good dump! Feel so much lighter! :D

Great news on the car Pete i think thats the least they coulda done being the high end customer you were! Your build wasn't exactly a budget build so why they left pieces of the puzzle out like dump pipes etc before the tuning process was beyond me?!

haha, you bad :)

Probably going 4" would be better but at least it will be 3.5" all the way should eliminate a bit of the back pressure he had when tuning it. It was an offer I could not refuse and I appreciated it :thumbsup:

Looking alot better.

Yeah exhaust is key - gotta get rid of the hot gas somehow.

I was going to go with the 4" dump and cat, but could not knock this offer back.

I did not mind having the 3.5" exhaust system back from the Cat as it was built to flow and once the gases got to the exhaust it would be cooling a little.

Soon find out how the 3.5" goes, maybe a week before it's done ?

You'll be fine with 3.5 all the way.

Will be excellent.

Thanks, do you really think that 1/2 an inch will make that much difference, there is a step down from the turbo to the dump and a step up from the cat to the exhaust. I guess it would have to be restrictive.

I have heard said that an 1" makes all the difference but never knew what they were talking about :)

Some rough calcs

Area of a 3 inch is 28.2 in 2

Area of a 3.5 inch is 38.4 in 2

Area of a 4 inch is 50.2 in 2

From 3 to 3.5 is 36% larger.

when it is put that way it is pretty impressive ?

what does 38.4 in "2" mean

He only got a rebuilt bottom end and some diffs put in, would hardly call it high end.

Not to take anything away from a 3.2 stroker of course

haha, a little bit more work than that, but not finished yet :)

Of course there is a lot holding this together but without nuts and bolts.

Nitto 3.2./ RB30

PT6262 CEA

9Lt sump conversion

supertech 1mm OS valves and stuff

head cleaned up

custom UE 260 10.8 cams etc

Koyorad radiator

Splitfire coils

ID 1300 injectors

Custom catch tank

Haltech ECU Platinum Pro R34GTR

Flex fuel sensor

HKS EVC 6 Boost Controller

3.5" dump,cat and custom high flow stainless exhaust ( 3.5" cat and dump now going in the car)

Nismo slave cylinder

coppermix twin C Spec

Quaife front diff

Modified Transfer case

Nismo 2-way LSD

Next to do after I get over this lot is,

CAI pod cover

Twin Walbro intank surge tank and fuel lines etc

Full Flex tune.

I know there are shit loads more you can do to your car to call it a top end build, but for a DD it is a pretty strong build that you can drive to church or get you to heaven, real quick, or HELL :/

I thought the turbo setup and fuel system was already on it for some reason!

The Turbo was on. Left a lot of boltons on the car and have been upgrading them as needed.

I had no idea when I started this I would go to this stage :ban:

They told me the fuel delivery was starting to be a problem, especially if I go for E85 and wanted to turn the wick up. Then, the surge tank would be a good idea. I am sick of worrying once I get down to 1/4 tank if I am playing.

Going to end up with a jumble sale of parts soon and all of them are near new :)

I would say a surge tank is a necessity even on a tuned 26 with good rubber. All it takes is one fuel starvation event and your engine is gone. Not worth the risk to be honest.

That will be getting done very soon, just have to get this sorted , then get the parts and book it in :)

Rubber is pretty good, 265/35 x 18 AD08Rs , they really grip!

LOL @ this guy! Are you serious mate? I don't know what Petes bill was BUT it'd have to be starting at $30K+ im pretty sure thats enough to be classed as a high end customer!

Sure there is blokes/GTRKAT that throw bucket loads more money at those blokes than Pete did does that mean he deserved a car that wasn't setup right from the beginning does it?

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
