GT-RS or high flow?? opinions??

[SouthernR33]

Hey guys,

I would just like some opinions on what i am planning to do to my R33 as the next stage and what other may recommend to do.

The goal is around 250 - 260rwkw's at around 1.2 bar (i understand some lag is expected).

I have already

FMIC, Power FC, AVCR, 3" exhaust with dump pipe, Bosch fuel pump, fuel reg, BOV, heavy duty single plate clutch. I am currently running standard turbo, injectors and air flow meter.

I have decided to upgrade my turbo, injectors and AFM in one hit and have the cash ready to go but the 2 options i can think of are

1) HKS GT-RS (brand new $2800 from Nengun performance), 555cc injectors (jap brand $650) and a Z32 AFM $300

2) High fow standard turbo ($1500 if i had to guess), 555cc injectors (jap $650) & AFM $300

I really wanna buy a new turbo as i don't like buying second hand stuff but i will save alot on getting my standard turbo high flow'd (even though i am not a fan of rebuilding the standard and using existing gate,actuator, oil & water lines)

If i was to get the HKS kit it come with new lines, heavy duty actuator and wastegate.

Opinions on high flows? Any advice?

Cheers guys

I just got mine highflowed. With this highflow set up i got it'll be very hard to reach 250 mark at 1.2 bar. With those types of figures you'll probably wanna get the RS.

However with my case being EPA'd played a big part in my decision to get it highflowed over a newer, bigger turbo.

Definatly go the GT-RS!!

Im definatly considering this turbo atm!

I used to have a high flowed stockie, with steel wheels but didnt like it at all!

You can get a GT30 with a nissan exhaust housing.

I dunno how much power you'll get out of that though.

I would look at something bigger than the GT-RS why not a GT2830 they give heaps of torque though the midrange and will make more power than the gt-rs

[pnblight]

i sore a thread talking about the GT3071R which had been compares to the GTRS ,and had better responce than the GTRS ,has anyone tried one of these or know someone running one of these

I got a GTRS installed couple of weeks ago and got 255rwkw at 1.2 bar still have standard air flow meter so have to get Z32 so maybe a bit more in it and some better resolution in the tune. My mods are very similar to yours full 3 inch exshaust, FMIC, PFC, nismo 555cc injector, exhaust cam, lightened flywheel and ceramic clutch, spitfire coils and bosch 044 fuel pump. I couldn' t be happier great balance of response and power. I my main problem now is keeping traction in first gear. Also got $300 back for old turbo and i does come with new lines, heavy duty actuator and wastegate.

i have seen a r33 that got about 250rwkw from it , but it was running std injectors with a fuel reg to boost the pressure so that might have limited it

i dont know what kind of response it would have compared to the gtrs

[thizzle]

the 2835 is rated at 420 ps gtr-s is 400ps and spools up alot quicker... whats 20 ps?

cheers guys....

I will check out the GT2830 and do some more looking at the GTRS. I am only looking at making around 250-260 so i the end my decision will reflect this.

[redline2003]

Is the HKS GT2XXX series still being made by HKS or has it been discontinued>>

[Cake]

discontinued

except there is now a GT2530KAI model which is rated at 364ps, more power than even the GT2540, but perhaps similar response to the old 2530?

[benm]

Interesting thread. Seems some people only make 240ish with the GCG Hiflow and others make up around 260ish.

I guess it depends on how much power you are making before you go the P/FC + Turbo.
