R32 Gtr Upgraded Dumps Or Not

[STATUS]

If you have them id say fit them.

OEM dumps are not that bad. Ive tunned engines with them making 320-330 atw's

obviously they are not the best thing but they work.

yeah the std ones are a little restrictive but even cats car made a lazy 330rwkw with the stockies. I prefer to use these, but dont have the cash right now ;

the little elbows dont seem to give the same increase as these ones.

Another lovely thread with stupid information from the usual suspect

are you trying to hurt my feelings?

I should rephrase - rev210, cams aren't necessary at 350kw, but can help

[blk180]

Maybe sould have said i have a built engine ie

87mm forged pistons

PAR billet rods

crank crack tested,xrayed and grub screwed

block bored,debrued,and decked

sump inlarged

N1 water pump

N1 oil pump

tomei sump baffles

tomei metal full gasket kit

head was services with bronze valve guids added

tomei oil resistors added

head to block oil returns bored out

N1 hamonic balancer

acl race bearings

nismo AFM

Power FC

Nismo Fuel pump

800cc Sard injectors

Sard FRP

so on

and was having a Hard intercooler piping kit fit, tomei poncams 260in/out

The exhurst is a FULL HKS twin exhurst from the turbos back.

Car only made 301Awkws@18psi with 750Nm on marine dyno. No dumps not sure why the low boost ethier but meh.

I've always found that if you put it of and do it later your only paying again to have the same parts your fitting now removed again to do it later .If you have them fit the while its down will save money later and time wothout your gtr

Uras what brand are those??

Ive seen and fitted a few sets that have been supplied by the customer. I know tomei do them but they look different to those.

Id agree with you they look awesome comapred to any elbow design dump.

[R31Nismoid]

The ones URAS posted are the TOMEI Splut GTR Dumps.

I have a set for my own car

Absolute mongrel though to fit, i did it motor out... i'd HATE to do it motor in, and i have a less cluttered engine bay in my GTS-R compared with a GTR

[WRRR]

In car fitting - aarghhh!

I had enough trouble fitting my custom 3" dumps/pipes on the bench. The back nuts on the turbo exhaust flanges are a real pita to get and be sure they are all done up properly.

I know a lot say they can be done in car but I'd really like to watch. With all that swearing and gyrating to reach what you need to get at it would be like watching porn. Oooh (said in a girly voice) that would most likely be gay porn - pass!

They are actualy the trust ones complete with front pipes

[rev210]

those trust ones are very nice.

Again just do the dump pipes, they are excellent bang for buck given the stockers put a muzzle on the horsepower.

I have a similar set up as you,but no engine work...stock..except for cams..

Look at the sticky RB26and you will find it...

If I were to have some major work like yours done to the motor...I would be expecting over 350Awkw's.

What turbo are you running....??

If they are stockies...don't bother changing the dumps.

What boost controller do you have....??

What are the cam gears dialed at??

Who did your tune....??

I have boost registering as low as 3000rpm......it is in the tune...dialing of the cams and the dumps help alot...

Ronin....mis-understood you... sorry about that...

[deant1]

I don'y understand why there was an issue of taking the turbos out in the first place anyway? if id bought new hardware it would be going on asap.

if the mechanic is charging to much for this job to justify the minor increase in performance just do it yourself, it's not an overly complicated job...

Anyway lol this topic has been around a while and you have probably (hopefully) fitted them dumps by now!!

[blk180]

Old dyno before cams and exhurst and only 15psi.

New on with cams and exhurst and 18psi.

I am running HKS 2530s as title

Boost controler is Blitz ID3

Cam dial in no clue thats up to Dart automotive the tuner.

They never said it couldnt be done they just said it was alot of money for small gain pulling the turbos out.

Anyway man problem now is that car is maybe a bit too loud with the new exhurst. Dumps are not fitted are just sitting on my desk will be done later down the track or may sell the HKS exhurst and get something thats not so loud.

haha, indeed they are TRUST

I was looking @ some TOMEI parts at the same time as replying... stupid me :sorcerer:

Id agree with you they look awesome comapred to any elbow design dump.

i'll have my car at greg's soon, you can get a good look at them

its ok hes on acid tonite

do you happen to own a pair of gtr worker monkeys?

yeah its an easy job but its very time consuming.

Close, they are GREDDY items. Originally designed for thier 700-800hp low mount T618z turbos (im not a fan, to big, too laggy) they found shortcomings with the twin elbow design and they found out that when fitted to the smaller T517z's there was noticeable gain also.

and yes mongrel to fit, but can be done... i dont advise fitting any brand of dump with the turbos inplace. It is a fairly quick and easy job to get the gtr turbos off if you follow a sequence.... definately some tricks of the trade.

Hmm they are rather nice might look into getting a set in to try on my GTR.

There certainly are a few neat little tricks to getting the turbo's on an off quickly. But once everything is removed from around the area its really not hat hard.

Angus smart which GTR is yours?? we see so many of them its next to impossible to keep track of them atm.

I think your cam gears and tuning is your problem...with your set up you should be over 350AWKWS...

You have excessive lag I believe because the exhaust cam is dialled to 0 which works well for stock Turbo's but for 2530's -6 is required.

You have the same AWKW's after the second tune at 100km's an hour than the first tune.........your lag has not improved for street use.

Do you use this car for the track?

Does your car feel responsive?

Your car after these cams should have been more responsive in the low to medium range...

Just my 2c worth...not talking bad about your tuner or anything else...

Cheers

Can anyone comment on the need with the trust/greddy dump front pipes (pictured above) to brace the pipes I think to the bellhousing

am sure I read on here somewhere that without bacing them it can cause drama's with cracking pipes etc

(from memory the pics on that thread were no longer working)

Am hoping to fit these to mine soon but using garret turbos, supposedly that makes the job harder than using trust turbos as well

Should be alot a fun but hopefully worth the effort.
