STAGE 2

Default Help with turbo choice and supporting mods. Looking for 325+ WHP on EJ205.

Basically looking to kick it up about a third of the current power and hit 325WHP or so.
Currently running at 245WHP stage 2 with:
Perrin TBE
TurboXS Intake
TurboXS BOV
Protune for Cobb AP

Obviously Ill need a Walbro 255 pump. But what turbo shoudl I go with to hit my power goal?
I dont want too much lag as Ill mainly be streeting/autocrossing with some freeway. Right now the stock turbo's response is great.

Im also looking for reliability since its my daily driver which is why my power goal is 325.
I figure it will last easily to 100k. Im at 60k right now.

What all do you reccomend?
Price plays a factor. Will probably be going slightly used.

With a small FP Green...

Default

18g w/ meth or similar set up. Some have squeezed this out of a 16g but their tuners are god.

i hit that power with my FP Green, but i chose no meth or E85 also the fuel is lousy in Hawaii. I also got a different clutch. Event though the 205's don't make alot of torque and clutches break on torque not HP it's a good idea to support.

Good luck!!!

DB super 16g, 650cc injectors, meth. my super 16g gives me full boost at just over 3000rpm's and with meth you should be in the 325-350whp range, w/out meth your lookin at ~300whp.

No 16g wheel flows enough for 325+ on a true uncorrected dyno.

Sorry to burst your bubble.

A td05H-18g with an 8cm2 turbine housing will. A TD06H-18g 8cm2 will make a bit more.
and a 20g of either setup will make around 325-350 on straight pump.

This is the problem with Nasioc. You have people telling you 350whp is possible with a 16g. Yea @ 30lbs of boost on Q/C16. It then becomes a dyno queen and its no longer practical to drive on the street with $9 a gallon fuel. Why not oversize your turbo a bit put it in a better efficiency range and make your power a bit safer?

<< Run an 18g to the limit and hate it. But I also have $100 into the turbo..

Go big, run less boost make more power...

The only thing that im worried about is breaking the tranny or ruining the life of the engine. Peopel seem to say 325-350whp is max safe for the 04 WRX block and tranny.

Do any 20g's offer quick spool? I enjoy the responsiveness of the stock turbo but its small and that initial into the seat moment leaves me wanting MUCH moooooooooore.

Hence why Im looking at 100whp increase.
I also figure I can do this for under a grand.
$600 for used turbo, Walbro for $85, injectors for ~$250, and biiiig TMIC for ~$200. Oh and of course Ill need it tuned. So maybe $1,200 total.

In my book $1,200 is worth it to be spinning all four and eating almost everything on the road. And when I eventually spin a bearing or something after 100k, ill just rebuild whatever broke with some stronger parts for $200 or so.

Im out of my power train warranty in 1k miles (60k). Soon as its kicked im jumping into the bigger turbo.

You wont spin all four. If your eating everything on the road your street racing...

Do some research.

Ive seen videos of 325whp spinning all four.
However, its not my interest to waste my rubber, it woudl jsut be fun to know its capable.
And eating everything on the road doesnt mean street racing it was implying almost anything encountered on the road could be beaten.
I go down to willows for AutoX.

Seriously, I cant speed on the freeway. Every piggy I pass does a brodie across the median within 2 seconds of passing me and then tails me for a good 10 minutes.

I had a trail of 3 of em when I drove up from oakland and finally took my last exit.

I appreciate your information but please dont be condescending.

Trust me.. You won't spin all four...

You will spin the front tire on a 5 speed. Once in a great great while the rear will break loose, but most likely not.

You should probably set your goals a lot lower as your in California and you have horse piss for fuel. So without meth 325+ isn't going to happen.

Yeah, we have 91 octane highest. :\
But I still think 325-350 is achievable with a reasonably safe aggressive tune on 91.

But back on topic, what would I need to achieve this?
Key notes:
Want to maintain fair MPG
Want some longevity of engine. (Want 100k at least,currently 60k)
Want min of 325WHP.
Want as min of turbo lag as possible.

FP Green?

I'm on the exact same boat. Well, debating actually.

I rather go with a smaller turbo and push it more than go with a larger turbo and have it easier. The turbo lag will take a lot of fun away I feel. That being said...FP green will spool no earlier than 4k...so you'll probably "feel" it around 4.5-4.75k...which won't give you enough room to play around..

18g hands down probably. Profile Coolrex.

HP numbers aside, if this is your intentional use, then you might want to consider (1) squeezing every bit out of the stocker, (2) Blouch's 19T upgrade or (3) a standard 16G.

The FP 68HTA is supposed to out flow the 18G with spool like a 16G. Look into that. That should be right around those numbers. A 16G will have a hard time putting those down.

TXS uses a Dynojet...

No graph was ever posted neither was a trap... And did you not notice in my post... I said 30psi on race or meth... He was @ 28psi on meth... It lasted a whole 3 weeks lol....

So I'm pretty sure my post was all but spot on. A 16g making that power is absolutely retarded in every sense. Buy a 20g loose 3-400 rpms of spool and be able to run 20psi and make that power...

Apparently a 16g on 93+meth wont sniff 355 for much longer than a couple of weeks.

I'm willing to bet that was with SAE correction on a Dynojet..

So, what would you guys recommend for 91 pump?
Id like to hit max boost by 4k max. anything after that doesnt leave much of a power band.
And Id prefer to do it without meth just to avoid any horribly catastrophic failures...

Remember, goal here is 325WHP+.
If I hti 325, ill be happy. If I get more I'll be overjoyed.
So am I looking at a 20g or 18g?
And what one? :P

What dyno? Whats your elevation?

A larger turbo will actually be easier on your drivetrain in most cases (unless you launch it) as it comes on slower and quite a bit smoother.

Your going to need a 20g for straight 91 to make that power. Or an FP Green.

91 is NOT a friendly fuel.

Get ready to drop some coin on more than you think.

Turbo + inlet + tune + clutch/or tranmission + injectors + engine + intercooler + retune after you blow your engine.

I'm hitting 325whp with a 205 and a TD06 8cm 20g, ewg and 19psi on 93 octain. Full boost hits at 4.5k rpms.

Im doing the best with what I got. And again, please dont be so negative.
Why would my engine blow? It shouldnt.

Also, I wont need a new clutch or tranny at 325WHP. Nor the engine.

I plan on doing it properly all at once.
Upgraded intercooler, upgraded injectors, 20g or FP Green turbo, and a Tune. Thats what I will be doing.
I might throw on an up pipe with EWG.

If the clutch cant hold it all Ill upgrade to a lightened flywheel and street clutch combo.

I'm being realistic.

Not negative..

Alot of guys can't keep their 205 together on a td04 let alone another 100hp worth of cylinder pressure...

Your 5 speed... Alot of people can't keep their five speed together on the stock tune/turbo let alone another 150hp..

I'm just telling you exactly how it is/might be.

1. transmissions can and will break at ANY hp level, though i'd say torque is more to blame for broken transmissions.

2. you plan on spending $65 for a tune? the tune is the most important part of the setup and you want to skimp on it? i'm reminded of an old saying, "cheap, fast, reliable...pick two."

Lol of course not, its just an estimate I made.
THanks everyone for your help so far.

Im doing more research and trying to decide what 20G turbo im going with or if I shoudl go FP Green.

I would go green if I could do it again.... Lag can be driven out of, what I mean is you'll only have it in the initial gear you "hit" and you can always downshift...Once your at wot lag is a non-factor...

At least with a green if the motor eventually goes its a great turbo for a built motor also
