Front Pipe And Dumps?

[joeleo87]

ive recently just brought a GTR yay!

Its got a cat back exhaust so im thinking first mods to get front pipes and maybe dump pipes.

at just as guess how much kws will i pick up after the dumps and fronts?

everything is stock atm apart from a mins ECU.

cheers

[JimmyRickard]

None if you don't up the boost. And if you do that's when the real fun of owning a GTR sets in. Sell your kidneys mate its going to be an expensive exercise

[GTRsean]

I second that!!

[nism0man]

install the pipe...take out boost restrictor...shood keep u happy for awhile

[heller44]

Throw it on a dyno and get an AFR plot.. never know what that mines ecu is set for, might be a grenade.

[joeleo87]

yeh right... never thougth about that.

im getting a bosch 040 pump to put in there this week, reason being i had to change over the fuel filter the other day and it was the factory stock filter! i weighed about 1 kilo, full of crap, so i figured its about time to change the pump as well. should i get an AFR plot before changing the pump?

[bnr#@]

Do the AFR after you do the pump

[Mr. Keets]

Front and dumps+mo boost then dyno...then wait for the ceramics to let go after a few days, week, months whatever and then your in the club

Seriously I'd get the tune sorted then leave it alone...if you want to keep money in you pocket that is. Pump's a good idea though.

[joeleo87]

i dont want to be in that club lol

well i bought a 040 fuel pump, yep just figured its not rly much of an upgrade lol. ill just buy a 044 pump in the next few days

[Tomei_33]

you wont need a 044 unless you join the club

[JimmyRickard]

you'll probably find that Mine's ECU of yours is tuned to Jap petrol (102 octane most likely) and it'll be running lean. A fuel pressure regulator is probably needed, and if you're upgrading the fuel pump make sure the relay is in good order, making a full 12V at the pump. As for the turbos, its just a matter of time. I've heard of people running 14psi consistently on the ceramics with no troubles at all. Me on the other hand, as soon as I took it to the track they clapped out after the 5th lap. $10k later and its back on the road

As for the dumps, fit them when your turbos eventually blow, it wouldn't be worth the cost of labour otherwise.

[CRoNic...]

So it's not recommended fitting dumps, etc to stock ceramic turbo's?

Even if you do, they're not going to explode unless you up the boost?

Explode meaning wheel lets go and flys away..

[JimmyRickard]

I was running standard boost when mine let go, so I don't think the boost level you're running has much to do with it. I wouldn't depend on it anyway.

[CRoNic...]

Did you have to get an engine rebuild?

Or did it just end up in the cat?

[Mr. Keets]

When one of my ceramics let go, 13psi, I went for 2860R-5's. There are a few knowledgeable guys here who believe that destroying a ceramic is a death sentence. My engine tested fine and continues to have good oil pressure after 17K on the new turbs. Cat...what is that lol

[CRoNic...]

Catylic converter - exhaust item.

[JimmyRickard]

Ended up in the cat - very lucky

[R31Nismoid]

some people shread motors when turbos let go, some dont.

Seems to be luck of the draw on that one

I think the sarcasm was lost on you mate

[CRoNic...]

Hahaha true...
