Some questions about going FI
Hey guys what's going on, I have a 08 g37 6mt coupe which I plan to boost next year. Lot more boosted guys on here that's why I came here to ask. This is my daily driver so not looking for an crazy amounts of power, just the awesome feeling of boost. :excited: So here are my questions, I am looking to make 400-450 whp on the stock block and stock internals. It's going to be the single top mount kit, the same as the one VSR/Vortex Motorsports in Tampa makes. Will I need to upgrade my stock fuel injectors and fuel pump? Will the stock clutch and flywheel hold the power? Will the stock Y Pipe/Mid pipe be okay with a turbo or will there be too much back pressure in the exhaust? All I could think of for now. Thanks! :tup:

Some questions about going FI
You'll need new injectors, pump, clutch, flywheel and csc. The exhaust will be a major bottleneck. Not to mention you'll need gauges, a boost controller, an oil cooler, ecutek or uprev and dyno time, plugs and most likely a new radiator. Budget $15k for the full package and an additional couple of bucks in reserve if the motor lets go.
Look into the BP kit. The vsr kit has some really bad decisions the way it's been set up. |

What Chuck said is the safest route. Do you need all of those items..no. I was making over 500 and never needed a radiator. The stock clutch holds 400. Oil cooler is dependant upon how and where you drive. Flywheel doesn't have to be upgrades unless your going for high numbers. You don't have to have a boost controller but they are nice.
You need to read on here...a lot. |
Chuck knows what he's talking about. I doubt you'll save much if any money paying someone to custom fabricate a kit for you.

"Going with DW fuel pump and GTR fuel injectors. Southbend quiet disk flywheel and stage 2 clutch" let me rephrase that, I would like to go with these things but I wanted to see if its possible with the OEM parts. Sorry for the confusion
|
The radiator is because most of us with boosted cars have higher than stock water temps. Gtr injectors are too small.
A top mount is bad turbo placement, but some people have made it work. |

The oem parts will not work. The clutch may need to be beefier, and the injectors are too small. Go with 600s at the minimum. |

Some questions about going FI
Sure, there are a lot of things you may not need at the outset, but it is always cheaper in the long run to replace parts before they fail.
Go bigger on the fuel pump. Get the 340. Headroom in the fuel system is a good thing. |

I'd recommend 750cc injectors too |
