Boosting my FR-S
 

Hi guys,
I am completely new when it comes to boosting cars so I need help boosting my stock FR-S. I have decided that I want to turbocharge my car and I would like to have around 400+ HP but no more than 500hp and similar amount of torque. Sorry if I ask obvious questions but I'm new so I don't know much when it comes to boosting. So, my questions are:

1) Which turbo kit is ideal for my car to output 400+ whp (but less than 500hp) and similar torque without having a lot of risk of blowing up the engine? I've heard fullblown turbo kits are nice but is there anything else that has better bang for the buck?

2) What is a safe PSI for the recommended turbo kit? Does having more PSI have an effect on the engine?

3) Should I run E85 or premium gas? I believe most of you would say E85 but I want to know what differences would I experience with these types.

4) Are there any other parts that I have to upgrade other than the turbo kit so that my car doesn't break down? If so, which ones are really required so that I don't risk having broken parts or blowing up the engine?

5) Would installing the Invidia N1 full exhaust help with the boosting process? (I really like the sound of this)

Please help me with these questions as this would be the first car that I'm ever going to have a turbo installed on.
Thanks

You have a lot of reading to do

For 400+ reliable horsepower, you better budget in some internal engine parts. As far as who can do it, talk to Full Blown, MA Performance, P&L Performance, AVO, any number of forum sponsors. They can all get there.

Lots to learn for sure, but there is some great info on here. You can also email me directly at ipeterson@maperformance.com with any questions you might have.

Your head is in the right place but you're very risk adverse...

To start out there's no way to boost the stock FA20 completely eliminating the risk of catastrophic engine failure. Naturally Aspirated FA20's fail due to oiling issues. Spend some time here and read up.

5-6psi is "safe" (in my opinion, based on my reading of threads here) but won't get you anywhere near 400whp. Making reliable power at those levels and above means putting in new rods, making oiling system and cooling modifications.

Visit owners threads, read up, introduce yourself and ask questions. Your journey is just beginning.

400 whp will require either e85 all the time or a built engine. Even on e85 it could still blow up.

400 whp will eventually kill the transmission. I did at 450. Then I killed another one. My car has less than 12,000 miles and has destroyed two transmissions.

Map and fullblown are reputable shops with alot of experience. I have a fullblown kit with a gtx2867r. I keep a spare engine around for when this one grenades. It's going to happen eventually at near 3 times stock power output. This car with 450whp is going to be difficult to drive if you've never owned something like this before. Difficult is relative. But spinning 3rd or 4th on the highway catches some people off gaurd. 1st and 2nd are useless when it's dry out let alone in the rain.

start with 280 ~ 300whp, I think its plenty for this car. Beyond that, is a whole new realm of parts/$$/long term reliability imo.

Read read and read some more

Btw you better have a big budget and a built engine imo for longevity at those numbers

You had me at "new to boosting" - you are gonna shoot yer eye out kid.

Hey I am new as well, but I know a lot and people here aren't really helpful. They know these things out of experience, the studying of this will be better.


1. Fullblown Stg 1 delivers around 300whp, stg 2 delivers more but then you would be looking to change internal of the engine since we only have 1998cc (2.0) of volume. It is not enough to run 400 without risking to blowing up. Is it possible, yes LOL but you risk 90% of blowing it up.


2. The higher the pressure the more it will be a parasite. The more the pressure the more the power though. Think of compression ;)


3. E85 is not a recommended fuel, but it is recommended if lets say you want to have full boost on the track or to have full power once. It is not expensive but the car requires more ethanol to do what petrol do.


4. & 5. Turbo = Air going in and a lot of HEAT
Then you need to get cooling parts (oil cooler, new radiator) etc
Oil changing is ideal
Exhaust to have what goes in goes out.. N1 is 2.5" of pipes.. you need at least 3" for that power........





Helpful how? Are you trying to increase post counts or something!

No.

How can you say that someone new to the BRZ/FRS and turbos is going to be safe in a 450HP twin? I stand by my post - it reminds me of Ralphie. Let's try the BB gun before the 50 cal.

The fact is this just another thread to add to the countless ones that are like this and filled with replies. You can't blame people for making the types off espouses they do sometimes.

Chances are the OPjust got the car, or is planning on getting it soon and has ideas running through his/her brain and is excited. Because of that, they just went out and asked a question to see what kind of info they could get.

Nothing wrong with that but a few minutes searching and you can easily find an answer and loads of info regarding every question asked.

Truth be told, I wouldn't even consider going past the 300hp mark without some attention the motor. That's just me though.

I'm incredibly helpful, I've told the gentleman who started this thread that all the information he seeks already exists on this forum. Imagine how annoying it would be if Wikipedia had 10 fucking pages for every topic. :cheers:

OP must not be serious, he's butt hurt already.

I see your point of view.

Funny how no one pays attention to the tranny, axels, etc, just on the engine.

Funny how so many don't know/are too lazy to search

@Mikeez my car has never seen pumpgas. E85 only for 12,000 miles. Tell me again why it's not recommended?

*sigh*

Therese's axles and a transmission in this car!? I thought it was an engine then some black magic that made it get to the wheels... :bonk:

Transmission doesn't like over 400whp. At 400wtq is doesn't last long at all. I havent herd about too many axles breaking but they seems to go around 450 with over an inch drop and good tires.

If you are serious - dive in and do an NA vette engine with a new tranny. Plus everything else that goes along with this much power.

Maybe new axles and drive train o.o forgot about that

Corrosion one day

Misconception. That's only if the E85 has absorbed any water, which is why it's stored in sealed drums. It's hydroscopic.

E85 corodes brass. There is no brass in our fuel system. We don't have a carburetor.

The FA20 can be fra-gee-le at times

Where the hell is the OP? @Team86, you alive?..

Thanks for the input guys. Sorry was busy with college but it definitely looks like I do have a lot of researching to do.

Welcome to my world :). I have Universit too @Team86 :(
Money for school goes first, then car. Seriously, don't jump into more than 350whp. Get it small and later on upgrade.

You don't necessarily have to go E85 to reach 400whp safely. There are a few ways to get there, yes E85 is one. Pump Gas (93) + WaterMeth can also get you there.

I think there are a few guys how have reached 400 on pump gas alone. This isn't something that I would personally recommend but it has been done.

@Mikeez yeah thats right have to pay student loans too lol. I think I might go with the FullBlown Stage 1 Base turbo kit at around 9 PSI running E85 to get around 350whp. Heard that you don't have to upgrade a lot of other parts and it's a simple bolt on kit which also sounds good.

I remember college. I went through the same struggle haha. I decided to go the safer route and do a Jackson racing supercharger and was real happy. A friend with the same car went turbo and blew his motor. These were civic si's.

I ended up needing money for school the following year and sold the supercharger kit. Supercharger kits hold their value far better than a turbo kit. Just something to consider.

Turbo and this car are not just a simple bolt on. Your in law law Land if you think this.

Finish school, get a career, a house then think of such toys....

Buddy, seriously you are on the same map as me. Check out my thread:

people on here helped me.


I am going Fullblown Stage 1, 7-9psi (GTX28)
You just have to buy the kit and upgrade the clutch. Don't use E85 unless you track or race lol.... Stay pump gas or else you will have to tune your car for both 91 and E95 fuel.. which is pointless for a student (LIKE ME)
1. Keep it 91/93
2. Keep I 7-9-12 psi MAX
3. Clutch
IF AND ONLY IF you live in hot area... You like to get your RPM all the way up to 7k... Get oilcooler. Very important oilcooler ;)


The rest is optional.
I shift at 2.5-3k and when I race people I shift at 5-6.5k ;) joke
Where do you live? What you study in? PM =p

Technically, they are bolt on as they are classified as bolt on.... Of course there are major modifications that has to be done. But the kit is classified as bolt on kit. I hope repeating made you understand. So please, be useful.


Do what ever he wants, whenever he wants. Its his life, not yours. You want to suggest something, suggest it. Don't give it like a must.

What I meant was that the turbo kit is a bolt on kit as fullblown also mentioned that. And I'm aware that I would have to get a good clutch, oil cooler, radiator, some gauges and a good tune.

No thanks. It's my life and my car. Don't tell me how to live my life. It's crazy how people say this I mean is it because they're older than me and/or have more experience. smh.

Just checked out your thread. Looks like we are on the same boat buddy! And thanks for the info. PM'd ya!
