Highflow Turbos

[RipNGrip]

Hey guys,

Just a quick question for all you Forced Induction Fans out there............! I recently had a rb25 highflow turbo mounted from sliding performance and i was wonder what is meant by the stages used to describe this turbo and others?

Stage 1

Stage 2

Stage 3

[Omurru]

I was once told that the "stages" in general can be described something like this:

Stage 1: "not bad..."

Stage 2: "scarey"

Satge 3: "ahhh! f**k me were all going to die!"

I don't think there is a actual classification for each and there could also be more than 3, normally sellers/shops/workshops just use them as a classification for the level of modification, ie, stage one basic mods to stage whatever heaps of mods....

Cool i have a stage two!

Instead of starting a whole new thread on highflows (sorry to hijack) I was just after peoples opinions on the following:

Ive just bought a Walbro fuel pump and Apexi S-AFC II and hope to buy an FMIC kit in the next couple of days. My understanding is that the SAFC can't really handle any sort of injector upgrade.

Anyway I am sorely tempted into buying a Slide High Flowed RB25 turbo. My question is, how much gains would I see from the highflow given that I can't really up my injectors. Would probably run the highflow at around 1bar. What sort of power would I be looking at? (Already have POD, boost controller and 3" turbo back zorst)

Like if im going to get around 190-200rwkw with the pump,fmic,safc and stock turbo would it be pushing the injectors too much to be hopeing for 230-250rwkw with the slide highflow?

haha depends what you call scarey

pretty sure i mentioned this in your other thread, but yes, thats hoping for much to much. stock injectors are good for 230rwkw AT THE MOST.. and thats running a very high duty cycle (not recommended). Not to mention, the lack of timing adjustment and proper fuel adjustment will probably make it very difficult to reach that figure in the first place.. if you did, it would be a bad power curve ....

once you highflow, your gonna need an ECU to run it properly..

haha the extra coin you shuold have spent on a decent upgrade....... jokes.

Hey lach,

I would say that SAFC, fuel pump, and FMIC probably won't make 190kws but thats just an estimation. I have a gts4-t with a walbro fuel pump, FMIC, stock injectors, stage 2 highflow from sliding performance, fuel pressure reg, ecu remap from mercury motorsport, splitfire coilpacks, K&N pod, and 3inch exhaust. i am 160 at all wheels on 16 psi which is just over 1 bar. its an rb20det

[WogsRus]

Stock turbo, splitfiers and supporting mods, 15psi, yeah i know it will die eventually, central 20 ecu and a SAFCII, made 217 rwKw.

i am hoping with a slide VG30 max overbore, with 50psi fuel pressure to and stock onjecotrs to get close to 250.
