Default FPGreen maybe??

Sooo, Im thinking about going with an FPGreen in the future, And I havent really seen too many pre-02 people going with something along those lines. I guess Im just trying to figure out if there is anything that would need to be upgraded, other than the obvious of course. Like maybe if my MAF wont work, or FPR needs to be changed. Anything odd. The motor is a V4 STi EJ20K, just fyi.

List-
TURBO!!
em
fuel pump
injectors
going fmic
ewg
? stock bypass valve hold up??
? MAF ?
???

And if there is something that wont work, what would you recommend I fix/ replace it with??

either way you are going to need something to tune with.

i think a fp 18g would be sick.

I have engine management *(em) on the list.

I thought about an 18/20g, but I dont know if it would be enough. Ive got 8k redline stock, so even if I hit full boost around 4k, thats still enough room to play with.

Id rather go a little big than not big enough.


Edit: I also though FPgreen because its about as nasty as I can get with a 2.4 inlet pipe also. I dont really want to go rotated or anything crazy like that.

I woud also rather not use meth inj too. Just plain ol pump gas turbo power.

I wouldnt worry too much about the 2.0 thing... there are plenty of nutty 2.0 eclipses and evos using the green... it is basically just a 50trim and will spool pretty fast.

The sweet thing about that turbo is that it starts making power as it is spooling and does not have the light switch on off feel of a td05.

I went with a 50 trim on my eclipse from a 16g and swear it spooled faster... It was the characteristics of the turbo that made it feel that it spooled faster. It hit full boost a touch later but made more power everywhere before full boost and it was a waaaay more powerful car.

Look into the simtek engine management for your car. You will be able to run strictly off map sensor and drop your maf sensor all together. It is a problem area of the ej20k.

Also advisable not to put more than 400hp to the car on the stock internals.

If overkill is what you need in your life get the green, I feel where you are coming from as I am definitely an overkill person and will be putting something larger on my ej20g, but keep in mind the more power you have the more you are exposing weakness in other areas. Be prepared to address those areas as you push for power.

so you think the stock forged internals arent the greatest? I already put acl race bearings in the motor about a year ago. Cleaned everything else up while I was in there.

i think its a waste

pnped 18g is more than enough unless you go hybrid

but i think turbos this large on a 2.0 unless your dragging is kind of missing the point what these cars are for.....

I maxed out my MAF w/ a TD05H-20G 19.5 psi and a conservative tune....
lag is ok...... full boost by ~3700 rpm

Something for you to think about...

Also, I would worry about the tranny as ver4 sti tranny aren't any stronger than the wrx gearbox....just different ratio and DCCD

Totally missing the point of my earlier post ^

2.0 is what the green was initially made for.... remember that turbo was invented for a 2.0 4g63 motor in eclipses and talons before they started adapting them to anything else.
The fp green with its 50 trim compressor wheel will start making power sooner than the 18g and starts pushing you in the seat as it is spooling up. The 18g hits totally different... feels like it has more lag and hits like a light switch.... nothing... then bam your in boost.

They will both get the job done and meet your hp goal... but have very different characteristics.

Again... You will expose weaknesses in other areas such as internals and transmission, drivetrain etc when you push the envelope.

you failed to see that the 4G63 is a superior motor to ANY EJ motor.

a green on a gsx/tsi/evo isnt a big deal.

it's considered big in subaru terms when it comes to small displacement.

This is what I was after.

What did you do about your MAF??

I was thinking about the tranny earlier, Maybe someone will trade me a PPG trans for my crotch rocket. . .


Also blkgm8

I just briefly checked out the Simtek ecu. Do they have much support in the US?? Pretty good price on that unit also. Any ideas if it works with stock crank/cam sensors along with the iac?

The 50 trim is considered big in subaru terms.......
I know of 1.6 hondas that spool that thing with no problem

Also I wouldnt consider a 2.0 sti motor inferior to a 2.0 eclipse motor.... different in many ways... yes... I own both and both have their strengths and weaknesses.

Case in point... my ej20g spools a 16g faster than my eclipse did.

I love my green! Makes 23lbs at 4100 and it dosent look back (2.0 stock internals running 350whp for 60k miles). Go green! If your looking to drag it I'd suggest getting a 50 shot to get it off the line. But after that the green will push you hard thru the gate.

Great! I was reading comments about this ECU the other day.
Saw on their site they only sell it already programmed through their dealers.
Is there yet any other way to buy one brand new and program it ourselves?

I can get you the software if you know how to tune... or I can help you tune it.
Pm me for more on this.

Also as I said earlier about the Green... Go for it if you have the guts to truly get it in and build a beast. Your car can be sick fast with an 18g as well, hell even the tdo5 16g will have you flying but they feel way different. You will find a lot of people on here preaching conservative to you, but in the end you just need to build your car for what you have in mind and dont let anyone sell you down from your goals, just be prepared for when things break... and build it stronger.
I have a feeling we will be seeing you in the proven power bragging section at some point in the future.... I know I will be there soon enough.

well last year before the track closed I ran a 13.1 @ 101 with just catback and stock everything else. since then I got a dp, el header and blitz intake. figure with a tune right now I should be 12s.



If I can sell my bike ill get ppgs before I put the turbo on. But I'm 90% sure I'm going with the green. I'm not an autocrosser and the car isn't my dd. just a fun fast project car.

What size injectors would everyone recommend?

Oh boy, I asked the seller about shipping on that simtek. Im really considering snagging that thing up. It seems like it would be a good choice. And if someone on here is familiar with it then thats a plus. I would hate to buy that em and not be able to find anyone to work with it.

the b16 or whatever honda motor you mention along with any inline 4 can spool big turbos better then an EJ due to the placement of th turbo.

it isnt totally inferior (the ej) but when it comes to making consistent big horsepower numbers, the 4g63 will out do it per dollar.

my td04 spools instantly on my ej205..im sure it'd spool even faster on a inline 4.

are you confusing torque with spool?

Dude... it really doesnt sound like you are speaking from experience here...

I know each of the turbos stated in this thread very well and based on the firsthand experience in my personal cars, I gave advice on the subject to the op. Totally not confusing anything with anything... Just giving the op real advice from real experience using these different turbos.

Go ahead and keep spooling your tdo4 "instantly" and let people who want to experiment with making real power do so.

You can be either one of two kinds of people.... one that reads this stuff all day and becomes an expert at what he reads.... or one that actually tries different things on his car and becomes an expert at what works.

That last statement is a general view and not directed to anyone in particular so please dont take it personal.

Holy crap, I just googled that and people are saying full boost(mid 20's) before 4k and flows like a 30r. Thats friggin nuts! Hmmmm other option!!


Edit: Went to the Blouch site and saw the dom2.5, looks like that could be a good option also. Do people really run those with the internal gate??

Well people generally run the Dom III on the 2.5 liters, so i would think you would still spool approximately at 4k or a little after?

I run the blouch 2.5r on my 05sti (2.5liter) i get 18psi at 3500 rpm, nice and conservative, fast spool.

Just got the grimmspeed pnp header and highflow x-pipe, going to do tgv deletes, and get a retune...hopefully i'll pick up another few hundred RPM of spool =D

fyi 2.5r is smaller than the fp green, i thought u wanted big and nasty 2.4" inlet turbo
