I'm picking up my Toyota 86 soon. While researching the car, I found a company called Sprintex that made a bolt-on Supercharger kit for it, and I also found a mechanic workshop within two hours of me that can source and fit it, along with providing an ECU remap.
I spoke to my dad about it, who's an ex-mechanic of 35 years, and he basically said it was a stupid idea, trying to bolt a supercharger onto an engine that doesn't support it, and said that over time, a ton of issues would pop up, including, in no particular order, diff, clutch, gearbox and the engine bottom. I raised what my dad said with the mechanic, and he said they make sure the PSI boost is kept in 'safe' ranges, usually 8-10PSI for a supercharger.
What are your thoughts on this? I want to stress that I'm not going to jump right in the day after I pick up the car. I'll be happy driving it stock for a few years, and if I feel like a need a bit more at the end of that, I may consider it.
Pls no hate, I'm not a mega-car guy.
>>14046949
4-6psi is a safer bet, and have a tuning shop to a professional tune
The transmission and diff can all take more power safely, and it just sounds like you want a bit more punch in a car that sorely deserves it.
>>14046965
That's what I thought. The shop quoted me near-on $7 grand AUD, which was for sourcing the part, labour to install it, and an ECUTEK re-map and Dyno tune. If I DO end up going for it, I will of course be getting all of that done. The mechanics have done a ton of these in the past and apparently haven't had any issues.
Do you think the 8-10 that they said would be pushing it, or that it's just better to be safe than sorry?
>>14046949
Get something fast from the factory faggot or buy used
Don't try to modify your shitty Toyota to be fast
12.5 cr isn't going to like boost and since it's na it prob has cast pistons as well. If you want a powerful car go get one otherwise do bolt ones and an Ecu and call it good.
>>14046998
It's already pre-owned. Don't be mean.
>>14047015
So you are paying for a slow used car?
Dude just spring the extra cash for something fast or just find something in your budget that's fast
Don't buy these fucking toys if you want something fast
>>14047025
Righto, whatever dude. I'm just looking for advice as to whether it's worth it and whether the car can handle it. Not looking for people to pick apart my spending habits or choice of car, hey.
>>14046949
Look, i won't be mean as i assume you already know it's not fast.
Just don't be 1 of those deluded drivers who thinks their 86 is a sports car and they're now the best driver ever. They're fucking cancer.
As for the supercharger, go for it. Mods are fun and you can make it slightly less slow.
For that amount of money though...if you haven't bought it yet, go buy a r32 gtr for 15k and fix it up for another 6k, those engines are fucking indestructible once you get a new oil pump.
And really, really fucking fast later on when you put more money into it.
Supercharger kits are designed with low boost to not harm the engine. as long as it says its for a stock engine on x octane fuel and it's tuned right it will be fine. (and make sure its from a reputable company)
yes it will wear the clutch more, yes it could hurt the diff if you're doing burnouts and launches and shit on grippy surface all day, but if you treat it kindly it will be fine.
the gearbox will easily handle the type of torque 8-10 psi will create. probably triple that honestly.
t b h he probably just doesnt want you having that kind of power. afraid youll end up wrapped around a telephone pole.
>>14047033
No it's not worth it. Fucking think about it man. You are going to buy a car that you think is too slow from the and you have to modify. Just get a fucking car that's fast from the factory or one that has had the mods done by someone competent.
It's not like the old days with 7.5:1 boosted honda running a rising rate fpr with stock ecu and a check valve. You can get away with wayyyyy more with proper setups.
It's DI, and with proper tune i wouldn't be overly concerned.
If you are worried meth injection with proper safeguards would be all needed.
Still doesnt mean you can go doubling the boost your tuned for or anything.
90% of the problems related to turbo cars are between steering wheel and driver seat.
>>14046949
should be okay as long as you always use premium and have some kind of knock protection/failsafe. rest of the driveline seems strong enough for 250whp all day long. clutch will wear faster but you can upgrade when it's dead.
>>14047006
the stock pistons have milling marks typical in forgings. not that it matters, supras have pressure cast pistons and those hold 1000hp on a stock bottom end
>>14047058
All in the tune baby, all in the tune.
>>14047036
Cheers dude.
I'm not one of those drivers. In my OP, it says I'm not a car guy. I bought it because it was my second car, it was reasonably priced, and I liked the look of it. I don't think I'm hot shit. I don't think I'm suddenly a fantastic driver. I simply think it'll be a fun car to drive through the twisty bits and I was wondering if I could safely eke out a bit more power. Nothing more. Yes, I could've bought a different car. Sure. But I liked this one. All I was asking is if I could safely get more power from this current one. That is all.
>>14046949
Sprintex are absolute garbage. If you want a supercharger as well as a tune that won't blow your shit up in 10k miles, get the Jackson Racing kit. 5k USD and comes with a CARB certified tune. You'll make more power than non-intercooled Sprintex s
>>14047066
don't trigger me senpai
get the cosworth blower m8, there stuff has been top notch for a long time now
>>14046949
Speaking generally (I'm not that familiar with the 86/brz), you don't need to worry about the transmission or diff breaking unless you're launching hard on stick drag tires. With regular street tires, you'll just break traction with more power, so you won't get too much of a shock on your trans or diff. You might need a clutch which can handle more power. I don't know how much power the stock clutch can hold.
As far as how long the stock bottom end will last, that's dependent on a bunch of factors, but having a safe tune is a must. Find a shop which knows what they're doing. 8-10 PSI is too much for a stock engine with such a high compression ratio, FYI. Regardless, don't expect your engine to last anywhere near as long as an NA one. If this isn't your daily driver and you're willing to pay the money when the engine eventually craps out, then throw on the supercharger. If not, keep it NA.
>>14047090
This is the sort of response I was looking for, thanks a fucking ton.
It will be my daily driver, so I guess I'll be keeping it as-is, at the very least for the next few years.
Cheers.
>>14046949
the hks kit seems like the best
don't forget to upgrade the drive line a little
>>14046949
The diff and trans will be fine if you exercise mechanical sympathy. The engine will be fun with low boost/good tune
>>14047120
>fun
meant to say fine
>>14047101
tldr; what dad said
stupid fucker doesn't deserve his smart parent
superhcarges put major stress on the crank, if you have the cash get a turbo kit
you can upgrade your fuel and get lower compression rods and pistons while you're there
>just don't step on the gas and it will be fine
>>14047222

not with direct injection and good tuning. easily with e85.
>>14047268
Yeah bro take the tune to stage 3 to get that full retard timing
>>14047185
Well you'd sort of expect someone with 35 years experience in an industry to have more knowledge that someone who doesn't have any experience whatsoever. Funny, that.

Kek. What a shit engine they gave the 86.
No one has reliably made a turbo it super kit that isn't heavily clunky
And when you do, you're spending like. 40-50K total keeping it running when you could've gotten a base vette that spanks it across the board and won't explode or overheat (n/a is goat)
>>14046949
You should be getting a Vortech kit
>>14047025
Post car, fag.
Bread on hood, timestamp, etc.
>>14047644
bear in mind it's di. it's not gonna pre ignite if no fuel is in the chamber during compression
>>14046982
If It was my money, i would go with a Vortech kit. It produces less boost at low RPMS, lower inlet air temps, and the powerband it produces is more fitting for something like this.
Keep your warranty nigger
>>14047680
Is the 86 dry sump?
How much power/boost/compression/etc (don't know my shit yet) can the supercharger have before you start needing to upgrade other stock parts?
Also, do the official aero accessories have any functionality or is it just aesthetics and dead weight?
>>14048667
OP here.
Old mate at the mechanics said they'd push it to around 8-10PSI, but another anon here said something like 4-6.
>>14047046 said that apparently if you treat the car right, and get it tuned after the supercharger is added, it should be fine.
Personally, I'm not gonna risk it for a while. I'll have enough fun putting it through it's paces in the twisties near my house. I was just thinking about future improvements.
>>14046949
>>14048667
Why dont you grow some nads and buy an S15 and put the leftover change into 250kw atw and have a cooler/faster car
>>14048693
>S15 made illegal in the US because burgers fear drifting
>>14046949
What's the matter, OP?
Couldn't afford to buy the car with the proper badges?
>>14046982
But turbo/superchargers are illegal in australia.
>>14049195
nigga what
>>14048705
I was scrolling down the front and didn't realise this was one of the ones banned.
It is now also on my fun cars were not allowed to have, but fuck you I'm gonna get one anyway list.
>>14046949
One of the WA anons had the Sprintex kit on his 86 and from what he was saying, basically add +50% more power and torque.
Which for what it is, isn't too bad really.
Lot of good gear in that kit as well.
>>14048705
More like burgers fear the japanese having a faster, better handling and better car overall for the same price as the Mustang.
>>14046949
Get a turbo, they are much funner
>>14047951
no it's not.
>>14049195
Well that's wrong, ya drongo
>>14049401
Low/mid range power with immediate response is more important for a car like the BRZ/FRS.
>>14046949
i was reading up on turbos for these cars. I think 8-10 was deemed pretty safe.
I think your dad is kind of right from what I read. I can't remember exactly what the details were but just popping in a supercharger or turbo wasn't the smart move. One of the reasons subaru doesn't just drop a turbo into it. Needs to be put in in such as way to accommodate the layout of the bay and mechanics of the car. Something like that. Read about one guy who did a custom install and they were talking about why the way he did it was much better and properly thought out.
I will wager that the subaru clutch will be able to handle the extra power if you do end up at a point to replace it look into an ACT clutch. They're pretty good although expensive. If you're gonna use a supercharger be sure to upgrade brakes and tires first.
>>14052498
Old mate I'm buying it from has already put on way better quality tires. Dunno about brakes.
A lot of anons (and dad) said basically that it's more in how you drive it. If you thrash it on the daily, shit'll break, but if you take care of it - and don't overdo it on the boost pressure - it should last a while.
I'm not fussed anyway. Not touching it for a while.
>>14048705
>>14049261
That's just because they were never released in the US market. It's not banned because it's too fast, its banned because of import laws and emission requirements
people sound ignorant af when they say that shit senpai
The Toyobaru isn't worth it. It's super heavy for a sports car. Just get a WRX, it's roughly the same weight and price. WRXs are not only faster, but far more practical as well and have a better aftermarket.
>>14052971
>It's super heavy for a sports car
>>14049195
What's the point of spending more than 370z money for something that'll still be slower than a 370z? They're similar cars, there is no back stay in the 370z but the back seat in the 86 is useless anyway.
>>14053088
FRZ for 25k, 370z 30k. Yes the 5k matters, FRZ is "underpowered" 370Z is "heavy"
>>14053099
OP wants to drop 7k on a supercharger, and running safe psi will still be slower then the 370z.
>>14053119
5k*, also maybe a little slower will it really be by that much?
>>14048667
>do the official aero accessories have any functionality
I know the Series.Blue has a slightly better drag coefficient than the standard car. Not sure how much of that is due to the under spoilers, or the extra panels underneath that smooth out the bottom of the car. Probably a little of both.
>>14052971
>Just get a WRX, it's roughly the same weight
BRZ = ~2,765 lbs
WRX = ~3,265 lbs
Not even close.
>>14053327
Add another 150lbs to the WRX because that's the usual difference between them and BRZ owners
>>14053088
BRZ backseats are usable in a pinch if you just need to drive some people halfway across the city. Totally managable for a 30 minutes ride if the people in the back aren't 7' tall or hambeasts.
>>14048705
It was Nissan's choice not to get it certified for US sale. Probably because they only managed to sell a dozen or so S14's here.
Bunch of fucking pussies, I say.
>>14053358
because BRZ are women
>>14053088
>>14053364
The backseats in the Genesis are useless for people too but I fit 3 tires back there once
>>14053374
Will I become a girl if I buy a BRZ?
Because I'm buying one immediately if that's the case.
>>14047036
A BRZ is a sports car you retard.
>>14047072
>I'm not a car guy
>I want to spend $7,000 on my car to make it less reliable but more fun!
Sounds like a car guy to me.
>>14053454
>A BRZ is a sports car you retard
For real. I always see people trashing modern coupes saying they're not sports cars but then go on worshiping the miata as the pinnacle of sports cars.
>>14053454
Mate, 'less reliable but more fun' doesn't mean I'm a car guy. I don't know dick about cars, but I enjoy going around corners quickly.
>>14053513
I hate the whole "x car is not a sports car" thing
If a car is designed to be fast and have a fun driving experience, its a sports car.
>>14053585

I appreciate your input.
>86
put a GT infront of that shit you fuck.
>>14046949
This is why you don't listen to spanner monkeys, there are thousands of charged Toybarus on stock internals because most of the kits are developed by intelligent professions like engineers.
I have a 2013 BRZ am am deciding between a turbo or the Innovate twin screw super. I don't want to go over 10psi. On the other hand, I am more likely to replace the whole exhaust, header, and tune instead and keep it NA. I already have Super Sports on Enkais so the brakes are the only other thing I would upgrade if that is even needed on a NA ft86.
>>14048667
I don't know how the motor in the BRS86 is, but I do know that older Subaru engines (EJ25/20) have notoriously bad internals and are loads of work and money to upgrade. Running low PSI will help keep the beating to a minimal but it's still gonna be a beating. Moving parts wear out, especially when you start shoving air into an engine to make them move faster.
As for aero, it makes a hell of a difference if you're driving fast on a track. Splitters/diffusers/wings all help keep airflow in a way that keeps you on the ground.
>>14046965
Ive seen carburetors run more boost than that
>>14046949
The FA20 engine is a very versatile platform, it's an engine designed to be modded, not to the same extremes as a 2JZ, but the stock internals on it are good up to about 400hp easily. It also comes with high-compression stock, you're never going to want more than 8-10psi boost without upgrading the block.
Most bolt-on kits that are designed specifically for the 86 are 100% fine as is, and will tell you if you need any other mods before you install them
>>14054723
>I do know that older Subaru engines (EJ25/20) have notoriously bad internals
Well, for starters the EJ began development nearly forty years ago. While the "notoriously bad" internals are massively overstated by /o/ and are mostly a result of the EJ25D shitting out head gaskets for a couple model years in the nineties. The smaller displacement EJ's are very reliable as long as you aren't putting crazy amounts of boost on them. This seems to be more an issue of Subaru owners and the stereotypes we associate with them. That's not to say that the current STI is using a forty-year-old engine, but having the best of an 'okay' decades-old engine design isn't exactly something to brag about.
The FA, on the other hand, debuted in 2013 and is based on the FB series that's more than thirty years removed from the EJ. To hear people discuss it here, you'd think it was a bad thing that all the things they've done to wring 100 hp/L out of a naturally aspirated engine are ruinous because of their preconceptions about FI and previous Subaru engines. As >>14054799 has said, the newer engines are designed with aftermarket mods in mind and should be much more reliable in stock form.
>>14046949 , here's a teardown with a lot more detail about the engine, and its FI potential.

>>14055391
>EJ25D shitting out head gaskets
why even have separate heads when the block is in two parts
