Slydr Just Been Tuned!

[flake32]

hey all i just had my r32 dynoed at hyperdrive, when i bought it i was told it had about 299rwhp with a miss, i wasnt sure so i took it to hyperdrive this mourning with spitfire coils and only pulled 265.9rwhp at 14psi, the boost was all over the place, the guy at hyperdrive told me the hks 2540 wont really do anybetter than that so anyway im gonna get a new turbo, any suggestions where to take it or what turbo to get??

cheers

bro theres rb25`s on the turbo upgrade section usen the same turbo for well over 300,

I had my car tuned this morning at Hyperdrive, its got a GT3082R with similar mods as urself. i went 330rwhp @ 16psi through a built auto box. had fuel issues so i could prob see 340 - 350 once sorted. i would go with the GT30 series ... they are not too laggy when tuned right, mine is very responsive and makes power through 7300rpm, pulls very, very hard =D

+ if yours is manual you would prob see closer to 380rwhp

and im sure yours would beat these apparent stockers making 260rwhp+ on 12psi, dont believe that for a second.

260rwhp isn't too much of a stretch.. my 20 with the 25 turbo made 245rwhp on the same dyno and my 30 with the 25 turbo made 243rwhp on the same dyno again, both at 12psi (different days account for the 2hp loss ) my mate has his 33 dyno'd at some place SOR and it made 296rwhp with stock turbo.. THAT is a stretch.. VERY happy dyno there!

[b4libs]

the 2540r should make over 300rwhp ive got one on my 180sx sr20 on 16psi and making 309rwhp

[Butler]

my stock 25 turbo made more power than that. smash some more boost in with a decent controller and get a retune asap. Are you 100% sure its a hks 2540?

[Kaido_RR]

i recommend the HKS GT-RS i think brand new from www.greenline.jp is 2.5k give or take...i've been in [Michael]s car and damn its responsive and powerful hahah or even the Trust TD06-25g or 20g but i would go the HKS because its coolant and oil cooled the Trust turbos are only oil cooled also the Garret GT30 series they good to hehe

lol thanks

if you got the cash go for the hks kits as they are bolt on and comes with everything you need or else just get a garret gt30 series turbo(everyone seems to like the 35r)

haha yeah 250 is not too bad, i had a redtop 20 with 25 turbo makin 240rwhp @ 11psi, but 270rwhp @ 12 psi i cant see happening unless its a freak lol

[IronmaskDR]

Dude i have a GT35R on my FJ20'd DR30 that makes 330rwhp @ 16psi and 355@ 19psi so I opt for the Garret, go to horsepowerinabox.com, they have direct replacement GT series turbo's for Nissan engines for just under the 2k mark.

P.S. The DR will lay SERIOUS rubber down in 3rd :}

[bubba]

I've heard those bolt on GT series use dodgy exhaust housings.. you can get a brand new GT35R for around ~$1800 *paid (1600 for mine but they were special circumstances). A lot of fab. work to be done though..

[rev210]

He's got a perfectly good turbo, not making the power it should. getting another one would be a waste of time till things are sorted.

[bubba]

Well he either needs to find another tuner (I like Hyperdrive and they do all my tuning, but they said his turbo is maxing out) or look at another setup.

He did ask about other turbos, I was merely pointing out that there are bigger options and that I've heard bad things about the horsepowerinabox turbos that use standard exhaust housings whereas real Garrett items don't.

yeah, i would be having doubts its actually a 2540 (given the tune is ok).

if its HKS, it should be marked on the front cover with HKS shouldnt it?

[ix9]

+ if yours is manual you would prob see closer to 380rwhp

and im sure yours would beat these apparent stockers making 260rwhp+ on 12psi, dont believe that for a second.

380, let's not go too far!

But 260hp on 12psi is quite easy for a stock RB25

Are you 100% sure its a hks 2540?

Yeah, check that out first

haha yeah 250 is not too bad, i had a redtop 20 with 25 turbo makin 240rwhp @ 11psi, but 270rwhp @ 12 psi i cant see happening unless its a freak lol

He has an RB25, not RB20

yeah, i would be having doubts its actually a 2540 (given the tune is ok).

if its HKS, it should be marked on the front cover with HKS shouldnt it?

I'd be checking too.

On the top of the shaft, in between the compressor and exhaust sides HKS stamp the model on the little silver label.

[showbizz]

yeah there should also be a tag on it usually behind the front side of the turbo

[sidewayssam]

yeh im trying to see wether it is actually a 2540 ive tried looking at the turbo but cant see it too well past the pipes and heat shroud, but yeah will let you guys know when i find out

[N I B]

About a year ago we had a Stock Turbo'd R33 go 298rwhp,It turned into a Topic on here but that one went 13.0@113mph.

[sidewayssam]

just had a better look with the torch to find the GARRETT on the turbo, did the 25 come stock with a garret turbo? i shall be visiting the guy who sold it to me now ... well its an excuse to get a new turbo anyway

[showbizz]

if it has garret written on the front it aint stock because the stock rb25 turbos have nissan (eg:http://www.imagestation.com/picture/sraid218/pdaf6db9e994775671341d8e5f6208cf4/ec08caf8.jpg) so if it was a gt2540 you could easily tell because hks would be written on it somewhere...

[sidewayssam]

tru, well so i have a garrett something, il probly take it in somewhere tomrow to see if they can tell me what it is... F#&KN Pi$$ed off tho, im gonna go see the guy who sold it to me and work something out

[showbizz]

not 100% sure if the stock rb25det turbo is actually a garrett someone could probably clarify it for ya...?
