Educated Guess At The Final Tune Results

[Nismo 3.2ish]

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

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

[Stixbnr32]

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 ?

Split the cost of the 4" with him to save doing it again down the track?

I will ask, but I think he started it the next day ?

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

[GTofuS-T]

what does 38.4 in "2" mean

in 2 = Square inches = in²

[Nismo 3.2ish]

So it is about 77% going from 3" to 4" , that is something

That's the one

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

[Nismo 3.2ish]

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

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

[XGTRX]

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?
