Rb25 Mild Turbo Upgrade

[simpletool]

It's prob the best turbo for highflow. They should a 2871 cartridge into it with the machined housings and you'll make 220 to 230rwkw without killing the turbo on about 15psi.

why would u bother slapping such a small turbo on a 25/30 build.

at least go gt30. ~300kw and full boost by 3000 which is amazing response.

Haha he actually means a 2530 turbocharger, not 3 litre with 25 head lol.

I wouldnt pissfart around with a 2860 with adaptors then maybe different lines (im not sure about the lines) Im pretty sure the dump pattern is different too. The adaptors are around $200 anyway, and would look shit. Theres 1100 already, plus custom dump, blah blah....

GO highflow. Looks stock, fits stock, least stuffing around, will make the power your are chasing. Theyre around $1300-1400 mark?

Thanks for all the opinions!

I have been doing some homework since starting this thread and i now see how dumb it is to stuff around with T2 turbo etc etc etc.

i have since purchased a VG30DET single turbo (4V54) with the OP6 turbine housing which i intend to get highflowed to 450hp through Hypergear with the ATR28G3 CHRA as its the most bang for buck optiong i've come accross.

if you only want 220-230rwkw... i had a hypergear, that's been changed for another hypergear. G2 profile, 71 compressor wheel. It's was a special one-off that Stao made, it was mid 220'srwkw (with some other car issues) with stock turbo response. I reckon those specs in an OP6 rear will be exactly what you're after.

I've just switched to a G3, 76 compressor wheel with the OP6 rear housing, and i'm not expecting stock response at all, but hoping for 260'ish.

The first hypergear i had sounds like what you're after, but i think the G3/76 might be a bit big for what you want.

Yea i understand what your saying but i want the headroom for future mods such as injectors, AFM, ECU etc.

how you planning on tuning it at the moment?

i see where you're coming from, but i don't see the need to go so big when you only want 200-230rwkw. Why not get that figure in the most responsive way?

you can do that with the stupid oem turbo.

[SS8_Gohan]

200 yes, 230 definitely not.

a stock response high flow will be 220-230rwkw, but unlike the stock turbo, it won't crack it at you if you want to run 15psi

[JMW]

Other option would be a high flow using std housings and 3071r cartridge, pretty sure its similar to HyperGear's G3

The coolest and quickest street car i have even been in was an R33 with Greddy inlet, baby 256 cams and a HKS 2530. The thing made boost and took off anywhere when you simply looked at the accelerator pedal. It was mighty torquey and punchy. It ran 18psi and made 230rwkws, though it drop back to 15psi up high in the rev range. There is no way i would say the turbo is too small. It hammered along very nicely

haha yea i forgot that i said i was only chasing that power figure.

But now i plan to have it tuned with the factory turbo after i get my new interdooler and boost controller which are on their way. From what i've seen i should make 180ish rwkw on a sensible tune.

Then I'm gonna save the cash to do the highflow, ECU, AFM, injectors, splitfire coilpacks all in one hit and aim for 240-250 rwkw

[SS8_Gohan]

what are you tuning WITH?

[stenve]

What exactly do you mean by baby cams? do you know what they were exactly?

Pretty much exactly how i want my street R33 to be like instant, torquey response

what are you getting tuned if you are running a factory ecu?
