The current ECU map wont cope with boost.
a 5th injector is an incredibly crude way of adding more fuel, a stand alone ECU would be alot better.
a set of injectors off a 200SX or similar might be a cheap upgrade.
I dont think theres space for a turbo down the back of the engine so youll need to gearbox mount it.
Youll need to find a suitable source for a high pressure oil feed.
Youll need a pipe welded to the sump for an oil drain.
You will need a map sensor, at least a 2 bar but you can get a 3 bar for the same price. Remember when talking about map sensors the first bar they measure is atmospheric pressure so a 3 bar sensor only measures 2 bar of boost
The GTi6 runs quite high compression (for a 90s hot hatch) and so it does limit the boost you can safely run.
You do need to consider if its actually worth it if your only going to run 6psi of boost. I know they reckon that if you add 7.35psi (0.5bar) of boost then youll add 50% more power but you need to consider the thermal losses and your power per pound. I reckon 6psi will see 220bhp and for the money of turboing it and setting up the fueling youd be far better offf (for the sake of both reliability and cost) building a cammed 2.1.
What is your experience with turboing cars?
What s your experience on modding a GTi6?
