6k to spend
 

2015 BRZ completely stock besides tires (Michelin A/S 3+). It's my daily driver. I want to make mine a bit faster. If you had 6k to spend what would you do?

SBD kit and all the supporting mods hands down. I love mine

Why not JDL new turbo kit?

Whats your numbers look like after the kit? Also looking for reliability since its my daily.

JDL is awesome too but is there an extra 2k or so to invest in supporting mods? Your also gonna want wheels and tires on top of that

Never cared to dyno it but at 12.5 PSI it almost keeps up with my dads 437WHP '93 ZR1 until 220kmh he starts to really get away. I would guess 300whp easy on pump gas. As far as reliable goes only issue that I couldn't fix on the side of the road was when I blew my rad up. Any time you go turbo your gonna have lots of issues but its worth it to me (mines also a DD).

Why is the JDL going to need any more supporting mods than the SBD? They are both complete bolt on kits. Any supporting mod needed for the JDL like tires and wheels are the same for the SBD.

I agree, they both need the same supporting mods (all FI does) I haven't looked at the price of the new JDL kit I just assumed it is higher because you know its JDL and they make top notch stuff.

Oh and to add if JDL is still doing UEL that's less desirable for spooling a turbo then EL

Edit: Nevermind they are the same price. SBD's website takes you to the 500x kit when you click on a feature for the 400x.

The JDL is actually cheaper at 3k for the base kit. It doesn't make quite as much power as the SBD but with the garret turbo upgrade it will.

And for the whole UEL and EL it wont make much of a difference unless a twin scroll setup is used. with the same turbo UEL and EL will differ very very slightly.

Honestly your probably right but in the real world wont matter much, but I am all about theory and science haha. I thought the SBD kit starts at 3k USD as well? Good deal

Haha yeah it does. I edited my last post. Their website took me to the 500x kit when I clicked on the 400x.

I'd say the main deciding factors between the two is UEL vs EL sound (personal preference) and open wastegate dump vs recirc wastegate (personal preference again). Both are great kits though!

Yeah its good to have choice at that price point now. I am on the fence about upgrading my turbo but on pump gas its honestly kinda pointless hahaha. Don't think you can go wrong with either


edit: SBD has amazing service and 1 year warranty

$5200 with a Delicious Tune

research more. save more.
a s/c if you want more reliability..
read read read

.... But less power :p (all else being relatively equal)

If you want reliability...Edelbrock supercharger or Jackson Racing. With Edelbrock you can use an authorized installer and get a warranty of sorts. Check out the forum section or Google Edelbrock and see the kit. As near to OEM as you are going to see.

^ that is true my buddy has one its been great to him, however power output isn't nearly what I am making but his drives really nice too

Yes, the power will be limited by about 90+ hp or so, it really depends what you want. Most say up to 300 HP is relatively safe, before supporting mods and internals need to be included.

I would say 400hp at the crank is kinda the margin of safety anything over that the risks go way up from what I have seen. E85 is also a good option for power and will save the OP a ton of money if he/she is only looking for 30hp or so

Thanks all for the input! I have looked into the supercharger also but I feel I want the power from the turbo. I wish I could get e85 but my area has VERY few stations that have it which is weird because in Louisiana oil and gas pretty much runs the economy and it's my profession.

I'm brand new to the mod scene and no one around me really messes with it. My warranty is up so I felt its time to start. Just trying to find a starting point. I don't understand much as of right now but been doing research.

Get a custom pie cut titanium cat back built and call it a day.

That's no strictly true - you can get more power than this by building the engine and dropping pulley sizes with a supercharger (e.g Harrop are running ~420whp on their kit with e85) although agreed that it's diminishing returns with a supercharger and for big power a turbo makes sense.

Turbo people seem to have more heat issues though. Not to mention all the drivetrain issues with going above ~400whp

And there is also the argument about how much power you need in this car. Is the difference between having 350whp and 450whp going to be transformative in performance terms? I doubt it. The only situation I could see >350whp being needed would be if you are getting in to 'highway pull' races against other powerful cars.

I would like to get around 300-350whp. The heat issues is what I'm worried about, being in Louisiana we barley have a winter.

I was referring to as-is. Yes, if you make further mods, then much higher outputs are possible.
