^That's 260rwkw. very nice.
Another happy GTRS person here
Response is awesome, I've got mates with bigger turbos on various different flavours of car, and on anything other than the drag strip mine is the quicker all-round package. not quite the same "shove in the back" factor though. If i had the choice again, I'd probably go with the 2835 ProS for the few extra $$, but that's just because i'm used to the power now.
re: GCG Vs GTRS - I researched this a lot, and i'm sure a lot of others have too.. at the end of the day the power outputs are similar enough to be the same; the GTRS maaaay be a wee bit more responsive, but there's really nothing in it.
But remember on the RB25 with that sort of power you're really pushing the limits of the stock injectors, and the stock AFM.
You'll find quite a lot of the guys with these, and larger turbos, have done the PowerFC/Injectors/AFM/Fuel pump upgrade gig.
edit : yep, i've got fuel pump / injectors / AFM / coilpacks / ECU etc ,run up to 17-18psi (but 15psi day to day)
but i DO know of a guy with a GTRS with just a SAFC and no other supporting mods.. he's had it over a year now with no dramas. yet.

the bloke i talked to about it was doing 12 hr shifts for 10 days straight then had 5 or 6 days off.
I'm on a similar roster... my life revolves around 13 hour shifts, 7 days in a row, then 7 days off, then 7 nights in a row, then 7 days off... rinse and repeat.
That's as a public hospital doctor in Melbourne. (intensive care)
If you want to experience the constant thrill of feeling jetlagged, come do what i do!
(actually i quite enjoy it. but it can kick your social life in the a$$ sometimes.)

Hiya kiddies
I have a Mistubishi Diamond Plus 93SB 19 inch flat screen CRT up for grabs
No marks/dents. In perfect working order.
One of the bestestest CRTs out there if you care to read the reviews (as i did before i bought it)
2 years old.
Only selling it as i recently moved to widescreen LCD
Can be had on staticice/shopbot for $450-550
Will happily sell for $250
Melbourne only pls - shippinog would cost a small fortune!
PM for more details/haggling etc etc

I was crew for *gasp* one of the EVO 8's (we came 11th in the Trussme car)
Great weekend. Bloody cold.
Couldn't get over how quiet that R32 was! quite possibly the most sedate exhaust i've heard on one in a while - proof you don't need a milo tin hanging off the back to go fast

Selling it for his dad? or possibly the car belonged to the kid, was driven by the kid, maintained by the kid, and the rego is in dad's name so the insurance can be in dad's name and the kid can save some $$$?
I'd want at least a faxed (signed) letter from the father allowing the kid to sell the car and act as a proxy, and DEFINATELY talk to him on the phone and make sure it's all kosher.
in all honesty though, i'd put my money on the car actually belonging to the son, and it was just registered in dad's name to make insuring it easier!

Unless you already have them, you'd be better off getting the PFC/Injector/GTRS kit from nengun (find it in the "product promotions" section). It's around $4K and easy to install yourself if you're half handy with a spanner.
This turbo is right on the edge of the stock afm / injectors ... to get the most out of it and for security you really need to look at a Z32AFM and either injectors or a fuel reg.
And yes *cough*search*cough* the lag is pretty much the same as stock, very responsive on the street, a great mild/moderate upgrade in turbo terms
You may not quite make the 250rwkw; get the 2835proS is you want that guaranteed.. but you'll come damn close if you don't.
I'm very happy with mine.

i had this problem.... if you email hotmail support with all the details of your account they will reset your pasword for you within a day or two.
you will need to know : the folders in your account, when last accessed by you, how many times a week it is accessed, and the IP address(es) you normally access it from.
They had me sorted within 24 hours last year with the same problem.

Are you timing with a G-Tech device or just using a stopwatch and the speedo?
Anyways; two reasons:
1) Larger wheels = slower acceleration. This is why a lot of the top drag cars don't use massive diameter rims.
and,
2) if you are timing using a stopwatch and your speedometer - your new 19" wheels have a larger rolling diameter, so 100km/h on your speedo is really more like 110km/h in reality, and obviously it will take a fraction more time.

The 230 sheet was NOT in shootut mode and done in January which is summer so if it was a hot day it would of read higher in shootout mode.
34 degrees, to be precise
I like to think i didn't care what power figure i got, but to be honest i was not too happy with the weatherman's prediction that day
and yes... Nengun/Greenline - look at their prices before you start worrying about the lack of 2nd hand GTRS's

^ i pulled 251 on a different dyno (friend of a friend works on commo's a lot in his shop and has one).
And as i said, people are making a reliable 260rwkw on that turbo, different cars, different dyno, different day.
I don't have aftermarket cams, maybe some of those do?
For what it's worth, a friend's ~260rwkw 200SX runs neck and neck with my lowly 230kw. He gets a fatter number on his dyno sheet. I still manage to sleep soundly at night.

comes on boost around 3000, full boost (15psi in my case) by ~3500, dies off around ~6500.
Lag is about the same as the stock item, obviously slightly more, but you're never caught lagging out of corners etc...
-
Back when i was looking at power graphs etc... they seemed to range from 230-260rwkw for the most part, with the occasional freak 290 or so. one guy has over 300!
You'll be right on the cusp of needing injectors (i did mine) or a fuel reg and a Z32afm (i also did this).
Much of a muchness between the GTRS and the GCG Hiflow.
very happy with my choice.
good luck!

You mean chip it?
I thought you couldn't reprogram the R33/34 ECU's, only the 32's?
I think you'd need to look at a piggyback/chip setup.

Nsta - i don't just use a heat shield, i have the pod in a sealed box, the only opening is the large hole at the bottom.
As that hole is the only way for air to get in to the box, i don't see why you need a pipe to help it get there? the stuff is generally fairly good with finding directions
That said, lots of guys use pipe.
I figured that the air below the airbox (just under the hole) is under pressure anyway - if you're moving forward, air comes through the front bar and hits the plastic guard that sits on front of the tyre (the grill that stops mud etc getting on the back of your old side mount intercooler).
So the air would head into the airbox with the sucking filter, as it's the path of least resistance.
standard hole is about 2-2.5" diameter. Might be a bit small and cause a restriction? i don't know - someone must study flow dynamics on here!!??
-
I used the same hole saw i used for the FMIC piping install to make it a bit bigger, and then drilled another hole right next to it, so there's about a 3" by 5" hole. did taht make sense?
I've seen a lot of pvc pipe used.
I don't use any pipe at all - it's still sucking cold air from outside the engine bay, as long as you have a sealed box setup. i just didn't see the point of an "air ram" when you're already running a compressor after the filter anyways...
-
With that turbo you would probably need injectors and a fuel pump to be safe, and also a Z32 AFM.
I think you'd be right at the limit of the standard AFM and/or injectors at that power level, and probably won't see the best out of your new turbo.
Why not just wait until the turbo is in; put the PowerFC in then and only get it tuned once and save yourself some money??
I doubt you'd need to lower compression at all.
Cams will net you maybe ~15kw extra, is it worth nearly $1000 to you?
Clutch - i'd look at a 9-puck or similar, but that's just my opinion. Still nice and driveable on the street.
(The dollars start adding up quickly if you want to do it properly!)
-
Hmmm. HKS quote 522kw for the twin GTRS setup at ~1.8bar
I take it that's at the flywheel? (since the SR20 figure is 294kw at 1.2bar)
Why such a difference in boost pressure for their graphs??
-
I've got an airbox in Kew if you like...
Good luck

^thanks
Made 230-240rwkw at 15psi with the GT-RS.
The tuner said he could have squeezed 250 out of it if i wanted the numbers on the dyno sheet... but i'm really just interested in a quick street car with lots of punch out of corners.
Turbo honestly is very close to stock lag-wise. Most impressed for what i wanted it for.
-
^do a search for " 2835* " and you will get at least two threads with pages of info on that turbo ; the installs with pics and any problems and issues along the way. From approx oct/nov/dec last year

I got that Nengun deal a while back.
Very happy with it.
It's currently $4250 delivered, plus tax/duty of course
I think the 260-270rwkw with stock motor and GT-RS is more the exception than the rule though, and you'd need cams to get that power figure. I'd say 240-250 is more likely from what i've read and seen. They CAN put out up to 300rwkw - but if you are expecting to get 260 out of one you should prepare to possibly be a little disappointed.
For 270ish i'd go the 2835ProS; it seems to be reliably making this sort of power. If you want HKS badge, that is.
And to be fair with the GCG Hiflows - a lot of people only get 230-240rwkw with those aswell. Sure some are getting 260, but i wouldn't say it's a guaranteed figure. Maybe they have cams aswell?
IMO the GCG Hiflow and the GTRS are pretty similar in response and peak power. i did a LOT of reading and enquiring around this topic not so long ago. The GTRS possibly has more in it at higher boost (18-19psi) but i only run mine at 15psi, which seems to be what most of the hiflow guys run at, for what it's worth.
The 2835ProS is a slight step up again; bit more lag, bit more top end.
Hope that helps a little.

near 40 degree days, hard driving, peak hour driving, temp has never budged from what it was before the blades were trimmed.

^that setup is fine.
You can also use the vacuum/pressure feed going to the BOV so it doesn't run over the top of the engine.
When you get an aftermarket turbo(
) it will probably have a nipple fitting on the compressor housing that you can use.

I think as a general rule with the correct supporting mods, GTRS 240-260kw, 2835 ProS 260-280.
Any other takers?
