I have a R33 GTS-t and currently have the following setup:

 Turbo back exhaust

 Hiflow filter for stock air box

 An oriface from benl1981 which gives me 10.5-11psi boost (depending on wat gear I am in) - http://www.skylinesaustralia.com/forums/sh...ead.php?t=70006

 And have a powerfc that I have yet to put into my car

I have the following questions:

 When I put the powerfc and do the tune will I need any upgraded components eg fuel pump, injectors etc?

 What kind of numbers should I expect after tuning given the above setup?

 I know that at some point that will need a few more fuel system/ clutch upgrades. How my rwkw is that when I need to worry about that stuff?

 If I am getting to this level, I don’t want to upgrade these at this stage so I intend to tune if for lower octane fuel. Is this possible?

 Would I get much benefit from an electronic boost controller and if I do get this later will I need a retune?

 Also thinking of putting a R34 GTT intercooler on the thing. What numbers will be getting then?

 Again will I need a retune for that?

 If I changed my muffler to a less noisy one will I need a retune?

 When do you need a retune – how necessary are retunes for new componentry?

My suggestion follow;

1. No

2. 25 rwkw is not unusual

3. fuel pump, ~225 rwkw, clutch when it starts to slip usually ~200 rwkw

4. Lower octane fuel? Nope, just run lower boost.

5. Yes, the PFC boost control kit would go well with the PFC

6. I have seen 215 rwkw from a car with an R34 GT intercooler

7. Not if your tuner has done a good job

8. Not if your tuner has done a good job

9. It does pay to check when you do upgrades, 10 minutes on the dyno and ~$50 may save you from problems.

Hope that helps:cheers:

All that stuff helps a lot

I have a few more questions:

- in wat ways will the electronic boost controller help the setup?

- if i changed the boost on the boost controller like from say 10/11psi to say 14psi will i need it to be retuned?

- on the described setup wat kind of rwkw numbers am I looking at?

- for tuning should i tune for for 95octane or 98 octane petrol?

- in wat ways will the electronic boost controller help the setup?

the bleed valve is essentially that, a valve it will just be open at a fixed size and nothing else. you get what you are given. with an ebc you have a device monitoring and controller the pressure level, its much more accurate and you can adjust boost directly by choosing a boost level in bar or psi whereas a bleed vavle you just keep opening until you get what you think its ok. and in different weeather conditions the bleed valve will spike whereas the ebc should keep it under control more. you can get ebc's pretty cheap nowadays, just dont get a brand new one and u should be fine

- if i changed the boost on the boost controller like from say 10/11psi to say 14psi will i need it to be retuned?

i wouldn't think so but it could help to check the af's make sure its safe etc. dont run 14psi on the stock turbo, youll kill it

- on the described setup wat kind of rwkw numbers am I looking at?

r33 + powerfc + r34 gtt intercooler + 10psi. i'd say around 170rwkw to 180rwkw. i have ths same except front mount instead of r34 gtt and im running 12psi and getting 172rwkw

- for tuning should i tune for for 95octane or 98 octane petrol?

the highest octain readily avaiable to you. so octain 98. always premium

    • Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.
    • Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).  
    • There's one for sale at Grand Auto Wreckers in Lonsdale (SA), for .... let's suggest the sum they're asking for will make you cry. You may have to embrace the idea of modifying the rear subframe to accept some other diff. You could probably find a way to wangle a shortnose into there, with a custom rear adapter and some sort of shenanigans to relocate the front mounts. This has probably already been done by others, so there might be some guidance available as to how easy/impossible it is, out there in the googles. But you possibly needn't restrict yourself to Nissan diffs if you're going to contemplate that. There are similarish Toyota diffs, possibly some Euro ones, possibly some Seppo ones.
    • The ball joint taper and arm taper have to match angle and diameter, but just doing the bushes is a much better option.....seems like the industry moved to "it is cheaper to replace the whole arm than take on the labour for changing this bushes", glad the aftermarket supports it
    • Gee she looks a bit rear heavy in that first pic! Sounds like a great project with the kids, but as I guess you know R series stuff is getting hard to find and pre that is pretty much impossible these days
