Upgrading Garret 2860-9

[avoiee]

i know lots has been covered on this subject but i need exact parts to supply my unopened rb26 to handle 300-330KW at rear wheels , i do have my opinion but maybe some stuff is ok from standard GTR and doesn't need to be upgraded . i dont wanna spent any extra $$ for now because i am looking to build 30/26 in near future . Just need your advice to get most out of my Turbos with not going crazy on upgrade list

Got Turbos Garret-9's no actuators

list of stuff i have already :

R32 GTR ecu and nistune

Boost controller

Apexi suction kit

here are list of stuff it might need to be upgrade ?

1) Dumps ? ( car is R33 GTR)

2) Front Pipe 70 into 80mm?

3) exhaust 3" or 3.5" ? (No cat will be used)

4) injectors?

5) Fuel rail ?

6) FPR - ?

7) Fuel pump ?

8) Mafs ?

9) Cams ? if yes what size is the best?

10) stock actuators can be used on -9 turbos? or should i change it for hks ?

11) Port Match Manifolds?

So if i am missing something just add, or if i wrote something not needed to be upgraded remove

Below is the picture of exhaust , your opinion its 3 or 3.5?

Don't need fuel rail or injectors and cams are a waste of money in your set up, even the standard airbox with a paper filter is perfect

Parts needed

-9s

Cam gears

Ecu

Injectors

Fuel pump

Clutch

Full exhaust

Boost controller

That is everything required to make 300-330 with a standard engine

[Hadouken]

Everything that was said above.

I run stock 33 dumps

1000cc injectors

Link ecu

Bosch 044

3-3.5" front pipe

4" cat

3" cat back (soon to be 3.5)

Cam gears

E85 @ 20psi = 340kw

stock Mafs? and if i swap my stock actuators on -9's will it be ok? wont hurt spool up time? i've read some were ajusting actuators helps in spull or something like that

What clutch are you using? NIsmo Single clutch should be ok?.

port matching manifolds?

so i'll just add cam gears , does it has to be Big name brand one?

So dumps, fuel rail, frp, Cams, Mafs - all these are ok with my set up

[Hadouken]

Your AFM's will top out around 300-310kw.

I run map with the Link ecu. I chose tomei cam gears, due to their design being different to the HKS style ones.

[maclarenf1]

also going down this path in Nov - i was advised to put in tomie pon cam shafts to provide a more fatter mid range. R34 GTR.

Car already has stage 1 stuff done apart from turbo's and running Map sensors with HKS F-Con.

[Joshbigt62r]

Call npc up for a clutch they recommend. Other option js jim berry.upgrade your mafs to series 2 rb25 ones. Cheap and will get you 350kw+.

[Joshbigt62r]

Camshafts are a waste of money for that power. Spend it elsewhere.

15+ year old RB26, I wouldn't go over 300 rwkW's.

here are list of stuff it might need to be upgrade ?

1) Dumps ? ( car is R33 GTR) - OEM Dumps should be ok

2) Front Pipe 70 into 80mm?

3) exhaust 3" or 3.5" ? (No cat will be used) - Either one is fine

4) injectors? - No need for 300 rwkW's

5) Fuel rail ? - No need for 300 rwkW's

6) FPR - ? - No need for 300 rwkW's

7) Fuel pump ? - No need for 300 rwkW's unless it needs replacing

8) Mafs ? - No need for 300 rwkW's, just run standard setup with Nistune

9) Cams ? if yes what size is the best? - Cam Shafts? = No need for 300 rwkW's - You might want to look into a set of Cam Gears for extra tunability

10) stock actuators can be used on -9 turbos? or should i change it for hks ? - Either way, doesn't hurt

11) Port Match Manifolds? - No need for 300 rwkW's

So if i am missing something just add, or if i wrote something not needed to be upgraded remove

Below is the picture of exhaust , your opinion its 3 or 3.5? - Ash's (R31Nismoid) general rule of thumb = 300 rwkW's = 3" exhaust / 350 rwkW's = 3.5" exhaust.

[Hadouken]

I would definitely replace the 15 yo fuel pump and injectors. One fails, engine goes lean engine goes boom

[Piggaz]

"Definitive guide to 300-330 rwkw". Pages and pages on this very topic.

True!

In that case (depending on the condition of his Fuel Pump / Injectors) replace them if need.

In future, if he's going RB26/30 and reaching for big power, might as well go aftermarket / larger injectors.

[Piggaz]

OP. what's your goals with the RB 30? You may find you're doing things twice here for no need.

Turbo and fuel setup for the big engine please.

oops just realized I made a mistake in the first line, it was meant to say "you don't need to change the rail or the regulator"

[r32-25t]

so i'll just add cam gears , does it has to be Big name brand one?

So dumps, fuel rail, frp, Cams, Mafs - all these are ok with my set up

any cam gears are fine pick ones you like and yes those parts are fine

Goal is what ever HKS T04Z can throw on it , 30/26 project for me is 1.5-2 year build , already got spear rb26, donor for head , sump and intake plenum, need rb30 now from Dubai , planing to buy one in November when i go there , around 300-500$ as i heard + all bunch of forged stuff etc list is huge . So that is why i just dont want to spent any extra penny on current engine upgrade etc. Want to have good relible 300-320wkw gtr with stock like response until i finish my new 30/26 on side .

Thanks To everyone for input and your opinions

Must do list is so far

ecu

boost controller

fuel pump 044

injectors (will do ID1000+ so i can use it for future build)

front pipe

Cam Gears

if mafs wont do its job then cheapest to go is Ford Lightning and messing around with suction compartment

Clutch - dont know what to use , maybe Nismo Single clutch with 1050kg pressure can work for me?

[Joshbigt62r]

Call NPC up mate they'll sort a top clutch out for you. Just tell them your setup and plans and they'll sort you a top drivable clutch that'll hold big power. Other option is call Jim Berry up and give him the same info and he will custom make you a clutch.

If your set on a Nismo go a twin plate super copper mix. Piggaz or R31Nismoid will be able to possibly elaborate more on this clutch. As they've used and still currently use the Nismo?

Josh

[avoiee]

Thx Josh

But i am located in Georgia , that wont help me shipping from Australia is always big $$ very expensive

[Piggaz]

Re the clutch. Don't bother with a single plate now, you will have to upgrade later on with the T04Z. Just straight to a Nismo twin plate competition model and forget about it.

agree save paying for a clutch twice
