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

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

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.

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.

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

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.

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"

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

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.

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?

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

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

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
