In a straight line (without a strong crosswind) the car feels fine to me even when topped out. But the car doesn't feel very confident taking a curve at 130+ as there's way to much body roll and what feels like unstable aero

Just swap the analg spedometer with one with high numbers (at least 200mph) and brag about
how fast the car is.

Oil coolers? Sure, it'd be a good idea.
BBK? Not really. Unless he plans on stopping very quickly from top speed, which is not a good idea as it would unsettle the balance of the car. Not to mention it's unlikely he'd need to if he's smart about it.
Better tires? Do you know what tires he has? How can you say he needs anything better?
Forged wheels? Totally unnecessary.

not sure what he's going for here. if want to bump the top speed to 150mph.. .then yeah you don't need to change much.

If you are talking about maxing out the stock gearing limit and shoot for 170-200mph or more. Then yeah you are gonna need way better brakes that can handle those sort of stops from 180 to 70mph over and over without over heating. I doubt the stock brakes could handle one hard 180-0mph test without cooking themselves.

Stock tires are rated to 165ish.. so if you plan on doing more than that you are definitely going to want to swap tires with a higher rating.

Wheels.Well theres a reason all pro racing teams and higher end cars use forged wheels made by Rays (volk, gram light), BBS, Enkei, HRE. I understand not everyone wants to shell out 4k+ for wheels but you get what you pay for. The cheapo wheels you get off tire rack for 250/wheel liekly have no certification or R&D behind them. no structural engineering.

Again if all your shooting for is like 10-20mph increase in top end. i wouldn't worry about any of this.

Haha I plan on doing forged internals and tranny and all that good stuff. I already have forged wheels and a good set of michilin pilot as3s.. I just need my turbo and then building my motor from there. Custom trans can be made though huh? They hold up well?

If you see some of the drag videos of the GT86 on the track running 10's, they barely can keep control of the car towards the end. It's so light.
I wanted a bullet, I understand it would be cheaper to simply buy a car a car with more power, but simply put, money is not an issue. I work hard to throw parts in my car and I'm tired of people shitting on the frs. Hell I might even do an awd conversion just for shits and giggles so I can have better control of the power.

Thank you for your input, but I wasn't asking how much it would be, I asked for guidance on how to get there. Also the mustang and camaro are too damn heavy. I will take 2700 lbs soaking wet as opposed to a sub 3800 lb boat.

Thanks for a legitimate answer..

I have coilovers and I'm getting turbo soon.. maybe a front splitter/rear diffuser too? Is power and aerodynamics seriously the only thing holding the car back?

I do actually plan on getting all of the things he mentioned regardless.. I do already have coils, forged wheels, and some very grippy michilin pilot as3s. I'm gonna get a bbk simply for the sake of it will be very nice to have some nice bite in the event I need to do quick stopping.. drivers on i5 just love to slam on brakes.. and deer are prevalent here in WA

Since you are going turbo, make as much power as you can then gear it for the speed you want.

Aerodynamically, I am no engineer but I would be looking at a functional splitter, the JDM underbody panels and a Drivaway Labs V1 diffuser at a minimum. If money is not a concern a complete customer and properly designed flat undertray going from splitter to diffuser would be worth looking at as it will reduce lift and not create as much drag as a wing on the boot. If you do some searching on the forum there are threads about aero dynamics from far more knowledgable people than me. A vented hood is probably a good idea too.

Do an LS swap then.

If you are concerned about stopping quickly, replacing your all season tires with summer tires (weather dependent) will do much more to decrease stopping distances than a BBK will. That, and get some better pads.

Sounds good man. I'll do some researching. That one piece style diffuser really sounds like a great idea, my only worry is I have the tomei 80r and the pipes in the front hang a tad low.. I'll figure something out though! Thanks again man!
