What's generally the next step (and associated cost) after upgrading exhaust? Injectors/fuel pump and then turbo?
Trying to figure if I'll be disappointed with just exhaust and tune, and should perhaps look at going one step further to avoid another wasting money on another tune in the future.
ninja edit: before anyone suggests, ethanol is off the cards, I just don't see it being a practical option.
MSR will recommend a new intake - $400 installed. He said it gives you 4-6kw across the rev range and makes the turbo spool up sooner. Plus it gives the car a great turbo whistle sound.
Exhaust and tune combined with the intake will be more than enough for your first step. If you wanted to go further you could get the bigger turbo like poida did but its going to cost you around 1600 installed on top of the rest of your work. And MSR pushes the blouch turbo's which are another $400 dearer than the VF52 that poida got.
MSR claims that changing the intercooler gains you nothing at the power we're dealing with and warns that its a big waste of money.
I looked at the fuel pump and injectors idea.. it will gain you some power but will obviously make you go through fuel a lot faster. I will eventually get the bigger turbo, but am glad im doing it in 2 stages... but if you have the money to do the turbo now, it will save you 300-400 on a retune.
Ok, sounds like you've got it sorted, intake + turbo back exhaust to stock mufflers and a tune, which is back at square one what MSR suggested anyway.
Experienced opinion was on the money, who'd have thought?
Re the fuel; I'd have thought fuel consumption was a function of energy used, rather than the fuel pressure/max flow rate the pump can deliver.
Just to clarify, you seem to think power limitations are due to turbo capacity at high rpms, and a larger turbo is "stage 2" per se?
