Can I get help with my goals?
 

As the title suggests, I have some pretty ambitious goals for my FR-S. Story time first though. I am a new car salesman at an unnamed Chevy dealership, they wont let salespeople drive the new corvettes at all (unfair), but I sold a Z51 corvette the other day and the man who bought it was kind enough to throw me the keys. So I took that beast for a quick spirited run around town and now I have a serious problem... my car is far too tame for my tastes now, which brings us to my goals, 460 HP and 465 Ft-lbs of torque. Now, I understand this is very far out, however this is what I want. the same power while staying as planted as that corvette was. I do not know what I need to do to achieve this, but I did see the crawford 450HP BRZ. Any help with a (long) list of what needs done would be greatly appreciated.

Might be cheaper to just get a corvette.

Give yourself a couple of weeks to mull it over. The tiny speedlust portion of your brain, buried deep in your cerebellum, makes a very loud and compelling noise about what you "must have", but it doesn't have any real staying power. Save yourself tons of bucks, gas and aggravation by relearning the excellence of the FR-Z system. Do you really think Corvette owners are happier than FR-Z owners the 99.99% of the time that they are not pressing hard on the gas pedal?

At $73k a corvette is definitely not cheaper haha

Turbo kit with a gtx30 with all supporting mods and e85. If e85 isn't available in you're area, you're going to have to build the block with lower compression pistons.

Have fun.

Have fun being in the shop all the time. I'd look for a used corvette. It would be a lot more reliable.

Yeah, actually it probably is. By the time you finish all the mods to an FR-S to give it 460 HP, it will most likely have cost you more than a new Corvette.

You're talking about extreme modification territory, and you're not thinking it all the way through to its logical conclusion. When Crawford put that insane engine into their BRZ, the first thing that happened was that the axle broke. Then other things that couldn't handle the torque and horsepower started breaking.

To make that work, they had to basically re-engineer the car. It's not just about bolting on a turbo and finding an extra 250 HP. And the final cost is not just all the go-fast parts that end up on the final version of the car. You'll have trial and error and broken pieces along the way, and every failure will add to the total cost.

I'm not telling you not to do it. But I don't think you're being entirely realistic about what you're getting into.

I'd reconsider that "definitely" part... :bonk:

I am on the side of the fence of just buy a corvette. However I also want to point out that I wouldn't say it was remotely that much. I have a pretty similar powertrain setup to me crawford and I didn't spend anywhere close to that price. But on the flip side heavily modified cars will be less reliable than a turn key production car. Small stupid things add up to reduced reliability with things as simple as not adding heat shielding to vacuum hoses. OEMs do extensive r&d to make their vehicles reliable

Also the z51 is heavier you won't need the exact same power to have the same acceleration. But you will spend a pretty penny to make your car handle the power and put it down properly.

To do things right I would say 15-30k in the car to have eveything done in a quality reputable manner. This would include a new engine, turbo setup, new transmission, driveshaft, diff, axles, fuel system, suspension components etc.

Have you seen how expensive it is just to get a "reliable" 250-300whp?? OP is talking about 460hp! That will take an extreme amount of time, money, and more money. It may not take a total of $75k to get there (That's including price of car), but keeping it reliable and constantly addressing issues and working out all the kinks...that all adds up.
If I all that money to put into a car then I'd just go for the Vette. That would save you an enormous amount of time and you can start enjoying the car from day 1.

Does that figure include the cost of parts you have broken along the way? Are you including both motors, including the one that slung a rod, or just the one that's on the car now?

You are forgetting one key point that the twins have and that's the power to weight ratio ya the Vette may have lots of HP and power you can feel but the twins have a lot of potential. Going fast in a straight line is one thing taking a good line while still being able to maintain a good speed through a corner is another. I suggest you take one of the twins through the canyons and cruise. Hell just even an ecu tune is good enough and you'll still be able to have fun.

OP, read this thread to give you some insight on the journey you're talking about putting yourself through.

The ending sums it all up when you realize all the time and money you've spent into modding your car is just really taking away from what you should really be doing, which is enjoying your time on the road.

I say get a Vette instead because from day 1 you'll be able to hit the road with a smile on your face, as opposed to taking a very long and expensive journey in order to hopefully end with that same smile on your face.

I think if you lower your lofty expectations and shoot for 350ish whp this could be done for a decent amount of money. To me if you want that much power you bought the wrong car to begin with. There is no denying the twins can use a bit more power but not 400 whp
