Turbo Or Ecu Upgrade First For R34 Gtt

[driftmeister]

My current mod is 3" HKS exhaust, Blitz downpipe, Trust oil cooler, std intercooler, std ECU. Intend to upgrade to HKS Type S intercooler + Boost Controller soon.

What would you think is next best upgrade, ECU or Turbo first? I am not looking for high HP but more streetable power when the need arises. From what i know is the std ECU won't boost more that 0.8bar.

If it was ECU, should i go for F-Con Vpro or Power FC? Pls factor in cost also.

If turbo, should it be HKS GT-RS or HKS 2835? What are the characteristic for both turbo compared? intend to boost 1.0bar for daily driving. Need advice...thx in advance

turbo wont work aswell without an ECU

so ECU is first

[Busky2k]

PowerFC.

Then grab a set of cams and a 2835 Pro S later on for some serious mumbo

What you guys think of the FCon V Pro? I know some prople who can bring the Japs and tune but quite costly. But it has one function that once the A/F is fixed to a certain amount, whatever boost you run the fuel will be optimized for it.

I like Power FC but is it easy to learn to tune by myself on the road or dyno?

1. In order for the FCon V Pro to "self tune" it would need a wide and fast lambda sensor and extensive interpretation hardware and software. I have not seen any evidence of that.

2. If you have a stand alone A/F metre there is no reason why you couldn't tune any (tunable) ECU on the road

cheers

Lastly, based on my current mods how much boost can my std turbo take if i upgrade to either one of the ECU?

Many thanks in advance guys. Cheers!

IMO, and sure this will be flamed by many other forum members, I just don't agree with buyign a powerfc, paying 500 for a tune, and then having to tune it again after you get your turbo.

I am still saving at the moment to collect all the parts I need and then i'm going to do them all in one hit.

Gotta agree with the post above - I'd buy the powerFC but wait until you can get the turbo and fit both together (and probably some fueling mods too)

Do both at the same time, along with all the supporting mods.

And remove the GTR badge.

what do you guys think of putting a SB8032, 440hp Garrett ball bearing core into the stock RB25 turbo covers? ive used it and gotten good results, just wonderin what other people thought of the idea.
