HKS GT-RS Installed

[redline2003]

Very nice result in my opinion. It seems the GT-RS is one of the best turbos to get for 250RWKW with decent spool time.

[nitemare5]

interested in the 1/4 mile time and trap speed. will be keeping a close eye on this thread

[knore]

what injectors?

[Col-GTSX]

yeah injectors who needs those????

Just drill em out.... LOL

[SLY33]

i also wouldve thought thered be more in it at that boost, bearing in mind i was initially a bit disappointed with 220rwkw from my old 2530, until i realised it sat next to or beat cars with 250+rwkw! while we all like to compare power figures side by side, at the end of the day it is just a figure and its how the car drives that counts.

Mark at MRC think something is holding me back some restristion. I dont expect much more from the turbo. There is heaps of mid range and top end in this turbo.

Injectots i have are apexi 555cc and bosch 044 pump with surge tank and standard pump running in boot.

It was a really hot day during tuning etc, not sure if the dyno figures takes that into equation but it was 45 degrees in the dyno room and didnt have a fan blowing onto the intercooler.

Will hopefully be out the creek on wednesday to run so if people are keen lest get a bit of a crew there. would not mind matching it up with a few others cars.

[croat]

saw boro's car last night......seems to pull really well

lets wait and see what it does at wsid

PS. Dont wear the same heavy shoes mate

Yogi will trying to get off work for wsid. Yeah have been trying to take it easy, its pretty hard tho. should come to the creek.

[thizzle]

no fan on the dyno wtf u expect tuning takes a hr or 2 at least at high revs 2 im suprised you got that much....

she musta been hot...

[siksII]

power sounds right to me, its a gtrs not a t67 or something what do people expect, (also taking into account the level of boost)

[SLY33]

power sounds right to me, its a gtrs not a t67 or something what do people expect

people expect more than 250rwkw over 1bar, since thizzle set the standard with his 250rwkw at 1bar!

but without cams i wouldnt expect much more than 250 even over 1bar. I wouldnt think thered be much more efficient flow left, if that even means anything..

[croat]

Just took it out for a run now, first cold night since i got it. on 1.3 bar boost at high rpm engine cut-out light comes on, was told that this is pinging although i cant hear anything. going to run it back on dyno to set timing back a few degrees.

I am sure thizzle made 250kw @ 1.3 bar, it is impossible to make it at 1 bar.

[siksII]

i would be very surprised if it made 250 at one bar, but then again who knows due to the difference in dynos.

anyway croat, if the engine light flashes it does mean that the power fc has picked up noise that comes up on the ping reading as (usually) 60 or more. if you have the hand controller you can check it next time, although it might have been a noise other than pinging.

[SLY33]

well 250rwkw at 1bar was what he posted after having it tuned at BD4s, only going on what he said. I used to run up to 1.3bar with my 2530, but then when tuning the 2835 my tuner said he didnt want to go over 1.1bar till i did the headgasket. Maybe i could run higher boost with the small turbo coz it would always drop right off at the top end, not sure.

[thizzle]

nah i never tuned on 1.3 boro...plus i had slippin clutch. and rushed tune cuz i wanted my car back i think i gave bd4s like 3 hrs on a friday arvo...your 1.3 is alot diffrent to mine man somethins holdin it back...cuz i pay out the ass for jap tuners and mechanics maybe ??on 1.3 i woulda got 260-265...your engine wasnt pingin man its runnin very smooth.. it could be tuned a little more i think...

post up the dyno show folks the torque lets see if they still would be dissapinted...

time to take it to yoshi :kick:

btw did ya block that bit yosh said to block up?? cuz ur using that catch can with the air filter on top??? wich results in you loosing boost..

[croat]

Nah have not done nothing yet matt. taking it tomorrow to take the timing back a few notches. will see how it goes...

[mokompri]

this is about the same power alot of people are making with the GT-RS on sr20det's, although with cams... they dont seem to flow much more then 250rwkw, if thats the power output your after, then the turbo is perfect for responce/power

if you go for some radical duration on your cams you may see more power... the turbines on these turbos are relatively small which does choke them up top when pushed

[Reedy]

I got a GTRS installed last week and tuned on saturday and got 255rwkw at 1.2 bar still have standard air flow meter so should be a bit more in it when I get it retuned with a Z32 or something similar. Other mods are full 3 inch exshaust, FMIC, PFC, nismo 555cc injector, exhaust cam, lightened flywheel and ceramic clutch, spitfire coils and bosch 044 fuel pump. Also great response and enough power to keep me satisfied and scare the sh!t out of my mates, also makes the car sound awesome as well.

[nitemare5]

any updates?

[Cake]

Reedy very nice, are the internals of your RB25DET standard?

Can anyone tell me how their GT-RS performed at lower boost such as 0.8 or 0.9bar, apart from lower power output, still responsive?

[FATGTS-R]

Reedy

Is that IT 50 or 58? its hard to read in the pic.

Also croat mentioned the dyno cell was 45 degrees but no fan was used.

Isnt that like crazy?

I would shoot any tuner dead on the spot that did that to my car.
