Bang for the buck - upgrades
 

I am interested in a list that give you cost/horsepower so it is easier to decide which upgrades to do next. I guess $ and Hp needs to be backed up with links to vendor pages and dyno test if requested. It is individual upgrades compared to a stock car. I will also include combinations of upgrades that has been dynoed in the bottom.

The data is based on manufacturers own dyno tests and MSRP prizes. The data my not be accurate and comparable. Quality of the products and a ton of other factors are equally important to consider when you buy upgrades. I a privat BRZ owner myself with no commercial interest in this other than I want to spend my money on upgrades wisely. (That was the disclamer :-)

Data so far:

Some upgrades can't be measured in hp.

A light weight crank pulley for instance shows no hp gain on a dyno, but reduces rotational mass to give you quicker throttle response.

Upgraded tires and suspensions also have no dyno gain, but take seconds from lap times.

Really, you're just looking at intake, header, and exhaust (as well as a tune). For most of these it will run $100 per 1hp/.7 tq. You could turbo for 5k and net about $50 per 1/.7

Visconti's tune will get you near that as well, and if you go to e85 it's closer to $20 per.

lol i was also hoping someone would make a chart or something so i can see which company has more HP per mod, maybe a column for claimed HP gain and user proven gains. this way when i go to buy mods in the future i can just look at the chart and have a better idea on what i want.

I fully agree with you. Ideally we should have testet all upgrades on a race track and a drag strip and found $ pr. 1/10 second with same car and driver. But the $/hp is simple and give you an indication. I know it is tons of weaknesses to this, but it could be interesting to compare whether you should put your money in e.g. an intake, headers or a ECU tune and see the cost differences between NA tuning and FI.

#1 is tires.

did this with my Spec-V and quickly realized that just because it was most $<HP didnt make it worth the $$...sometimes personal satisfaction is better than #'s. I am def not a fan of trailer queens or maintaining a nice paint job but sometimes what sounds better and looks better (and a company'spolicies/values) is more important than $<HP... just my .02 (although if you do get a sweet spread sheet going i will def. use)

Run on treadmill. Lose 20lbs. +10hp. $0. Thats what I did. no joke.

More often then not your HP gains will not stack one in each other either so just because you got a exhaust that gives 15(nameless and SRT) and a filter that gives you 5 and a tune that gives you 15 just remember you will probably not end up with 35 HP more.

E85 stage 1 is the most promising na upgrade so far netting 35hp over stock. Really wish we had the corn juice up in Canada, we do grow a lot of the crop that it gets made out of.

Anyone watch Might Car Mods? Paint your brake calipers red and you are guaranteed 25 extra kW!

Now this is not a power mod however I just covered the bare non-deadened metal of the FR-S's trunk and door/door panels with FatMat. The car stepped up a class in cabin quietness. While technically the car is slower b/c of the added ~10 pounds however its hard to quantify how awesome the car is to be in during extended trips now.

Toyobaru FR-Z is on a different level of playing field then the rest of the coupe in the market. Front engine rear wheel drive is the definition of fun. Enough said, I like to tackle touge on my free time I’m currently on stock setup, upgrade HID headlight that about it. FR-Z is very well built car from the ground up, the stock suspension is stiff enough for track and canyon driving. If you are looking for a list of upgrade $$ > HP increase then this car is not for you, I would recommend you to please sell your car to a person that can really enjoy driving rather mods car. You can truely appreciate this car if you learn how to drive it well, mods are fun, upgrade can be costly, but in the end is the driver (are you) good enough to drive the FR-S.

uhhhhhhhhhh are you suggesting everyone who mods or plans on modding these cars should sell it, because they dont appreciate it? or because they want the most bang for their buck? Im not even sure if i want to mod the car when i get it, but JUST IN CASE i do. i would like to have a spread sheet to look at instead of reading through every thread. If anything i would like to get rid of the torque dip that people speak of. Im sure the car is fine the way it is, but im pretty sure a pulley, ecu, intake upgrade would be nice.

Well look at it this way, if you want bang for your bucks then why not buy a 2013 Genesis Coupe 2.0T 260HP@6000 and 260@2000 Torque. These are impressive numbers with more bangs for your bucks, with the Genesis being $27,375 and FRS $24,955. With $2500 more on Genesis you get 60 HP and well over 100 Torque. Can you try to spend $2500 on mods and try get the numbers on FRS?
