Time To Upgrade

[Scriblez]

Hey Guys,

I'm Looking at potentially starting the next lot of upgrades for my S2 RS4 (depending on results and costs). I have some questions around this before I begin.

Currently I'm running: Blitz FMIC, Nistune board 4, Splitfire Coilpacks, Drift POD, HKS Turbo Actuator, 3.5" Turbo Back exhaust, Blitz i-colour Boost Controller @ 12PSI and Walbro 500HP fuel pump, Project MU Brakes.

After getting tuned at Turbo Tune, the car was able to produce 180AWKW.

My question is: What kind of power gains can I expect without upgrading the Turbo (is it pointless doing this?). What I mean is, If I upgrade my injectors to 440CC and get a Z32 AFM+Tune, will it be beneficial to me without upgrading the Turbo? If so, can anyone estimate the kind of gains I'd be looking at, or whether it would be worth it without upgrading the turbo? The reason I ask this is because my Budget is limited (like most of us) and I can't afford to upgrade my turbo and do the rest at the same time.

Here's a few pics of my Stag, been a member of these forums for ages and never put any pics up

Cheers

Bigger injectors and Z32afm will not give you any more power with the stock turbo.

It would be better to spend the money on a turbo or just a better tune - I would have thought you could get at least 200awkw from your neo engine.

With a better turbo ( ideally a new one but Hypergear ones seem to do the job) you can just wind up the boost and tune till you max out the injectors and/or afm - say 220 - 230awkw. Then if you want later you can get the Z32 afm and some bigger injectors and go for broke.

Ask around for the best tuner in Adelaide (preferably an Rb specialist) as a really good tune is the key to safe maximum performance.

Cheers Bob, I figured as much mate. Guess I'll just have to bite the bullet and get my Turbo Highflowed then. I'll have a chat with my new Tuner about power output with existing mods (I thought I would have cracked 200 as well)...

Cheers.

haha Cheers mate!

Bigger turbo, Z32 AFM and injectors + retune then there is some extra power to be gained. IMO don't go too big on the turbo bigger isn't always better to drive.

exactly but shouldve made 200-220 with stock turbo, dump, cat back and fmic though.

nice abflug kit btw.

Ok cheers for that guys.

I'll look at the Highflow option then I guess. Might have to save the pennies up for the time being

@dirtyRS4, good spot mate! Not many people know what kind of kit it is

And don't forget gearbox...recon the limit is 220 Kw. in std. tiptronic and 250 with shift kit (correct me if i'm wrong)...very nice ride mate ,it deserves more power...

It definitely deserves more power alright, all on the cards
