Wanting to build a motor and go FI
Currently, I have wheels/tires/coilovers/diffuser/front & rear sways. I'm wanting to add a turbo and this is what I came up with as far as setup. My goals are to get 400-450 whp, as a DD. I would track the car maybe 1-2 times a year. Is there anything I'm missing or is this overkill?
Turbo: Full-race EFR 7163 .80 A/R $7,135 Internals: Radium dual catch can Exedy Stage 1 clutch CP Low comp Forged 2618 pistons Manley I beams Perrin Engine mounts FBM Walbro 485 Fuel pump Velox AOS Flex fuel kit Internals + supporting mods: $6000 Labor: 30 Hours @ $85/hr ($2,550) Tune: $600 Total: $16,000+ |

I intend using the same kit, but not going to build the motor as only shooting for 350whp with E85; plus seems to be a reliable number while having fun.
From my own research, you may want to consider transmission mounts. Also, if you plan on not showing you car sympathy, be prepared to blow a tranny at that power level. Not saying it will happen definitely, but definitely a risk. A few people have blown their gearboxes; 4th gear is usually the culprit. Even if you go to Velox's shop car thread, he blew 4th gear and has pictures of inside the gearbox; mind you he is running just under 400whp. Also maybe consider axles, but not too sure if that is a real necessity. As you upgrade one weak area, it will just move it to another part of the drivetrain. Never ending loop on blowing money. Isn't it great!!! |

Also, the stage 1 clutch definitely won't hold up. if you are going for over 400whp, you will be pushing north of 300 ft lb at the wheels.

It's so easy to just think POWWERRR!! I use to think more power the better. Just need to think what you want, why you want it and then go for it. I have read countless times it becomes a money pit. Good thing I came to realise this prior to dumping money into the car!! At the end of the day, there will always be someone with a faster car. |

I've had around 250whp for a while now, and I'm thinking another 40 whp on top of it and I'd be just right honestly.

So no someone won't always have a faster car. A better way to look at it is, does the car do what you want it to? And that can mean being the fastest car on the street track. Just be realistic on the dollar amount and out skills required to get to your goal. Jaden |

I'm in the same boat, at 240whp. As other people have said on this forum, I really think 300whp would be an absolute sweet spot for DD with a bit of track. Fast enough, but doesn't overwhelm the grip or dominate the feel of the car, or break components of the drivetrain.

With E85 it's definitely doable. I personally am not shooting for 350 exact. Anywhere in that ballpark is more than enough. Over in the full race thread, most are running closer to 400 with no issues after over a year with track work. Their issues are more gearbox related, hence why I don't personally want to shoot for the stars. Plus with a bit of mechanical sympathy, it should be more than reliable. |

A few motors have gone on flex fuel around 320-370whp. But anyway, to the OP, good luck with your build, should be absolutely rapid. Maybe if you are going to be putting in close to 20k then also have a read through the engine swap sections on this forum as an option. |
