Default seeking input for build

Alright,


so i have an 06 sti. hit the lotery with this find. 71k miles, no mods. brand new built motor with some aftermarket internals. oem oil pickup tube cracked. blew original motor. killer b tub in now. new clutch kit. all paperwork provided. single owner. clean bill. got it for 14k. have 5k left to play with.

i want to put in a cobb stage 2 kit (catted downpipe, catback exhaust, access port, cobb shortram intake. turbo heatshield)
- i know this will require a tune

get some wobble in brakes when above 85 so want to install and upgraded brake kit ( new dba4000 series tslotted rotors. upgraded pads and ss brake lines)

perrin turbo intake

and some cosmetics upgrades for eng bay (perrin alt shroud. ect.)

grimmspeed A/O seperator i already installed.

and i wanted to put in a new pump. main question is......

1. if i put in a DW300 pump will it run fine through stock injectors or should i upgrade?
2. at this point i will be running out of money set aside and have to delve into other funds. if not would the DW1000 drop in injectors work fine?
i have read mixed reviews.
3.or should i put in injector dynamics 1000cc top feed with rails. wich i will have to dish out another 250 just for steel line conversion for my car? and if so is this even necessary for my build?

any imput would be very much appriciated. ill upload pics later when i can get them on the pc.

Unless you are going to run a bigger turbo or E-85 you really don't need bigger injectors and a bunch of expensive fuel line accessories.

Brake upgrades are good, especially if they replace your factory lines with steel ones.

You dont need injectors or fuel rails for your current list of mods. Hard wire a DW300 or a Walbro 255 and be done with it. Injector Dynamics or stock, don't risk any other brand.

Stinks I have to say this, but those GS AOS are considered by some useless. I would rather see a different brand myself. IAGs is nice, What aftermarket internals are in there and what was the PTW clearance, and was it properly broken in so that there is minimal blow by?

"GS AOS are considered by some useless"

I spent weeks researching this before purchasing mine. Seems like under track conditions (high g-force turns) the GS AOS is, in fact, pretty useless. However, if you are daily driving the car with the occasional spirited drive, the GS AOS works really well.

I have had mine on for about 2,000 and just took off my intercooler and it is spotless - not a single speck of oil. I also get fewer puffs of white smoke on start up, and I have noticed a significantly less Fine knock learning and Feedback knock.

it started consuming 1qt of oil per week so i took it back to eng builder and had them rebuild another one with upgraded parts. all available GS gaskets, rest oem. gates belts. perrin crank pully. ACL bearings. not sure on clearence, but i plan on properly breaking it in before any of these new mods go on. just trying to get a feel for what i need, and do research. this is my daily driver and dont plan on being tracked. i got the grimmspeed AOS over the perrin only for the fact it mounted ontop of the fill spout in hopes of solving my oil consumption problem. as it did not i do wish i had went for the perrin one. if i do not need the injectors i was contemplating getting the perrin one.

Tell us more about the engine itself. I'm curious why a built motor was chosen when this will be a daily driver. Which built internals were chosen?

the rotors are a waste of money, just get blanks.

stock lines are already stainless braided.

Actually, yes, being an STi stock rotors are fine.

So the '06 STi has SS braided lines stock? That's cool -- My '06 WRX did not, when I installed a StopTech kit it finally got them as part of the package.

I don't remember on the 07s but my 2011 STI had rubber brake lines.

The GS AOS is mostly fine for stock motors, but once you start cornering hard on aggressive autoX tires / suspension it can be overwhelmed. With a built motor you might be seeing more oil blowby than stock due to larger piston-to-wall clearances - I would probably go for an IAG myself personally, but you can always check your intercooler and see if oil is accumulating before you decide to replace the GS.

As others have said, fuel rails aren't needed. I would suggest ID1000s for injectors as the stock injectors will be close to maxed out on a stage 2 tune, and it's recommended to run injectors <90% duty cycles. Injector Dynamics makes the best injectors. DW fuel pumps are okay - I ran a DW65C for a year and never had an issue.

Otherwise your mod list looks pretty good.

i want to put in a cobb stage 2 kit (catted downpipe, catback exhaust, access port, cobb shortram intake. turbo heatshield)
- i know this will require a tune If you stick with exactly what Cobb has developed one of their tunes for, why not use one that came with your AP? You could even save money if the Cobb dp hooks up to your stock exhaust. Why change it?

get some wobble in brakes when above 85 so want to install and upgraded brake kit ( new dba4000 series tslotted rotors. upgraded pads and ss brake lines)
Blank Autozone cheapo rotors are the way to go. Otherwise, if you're simply wanting to pay for bling, go for it. Those dba rotors will do zero for performance over run of the mill stuff. You don't get much out of "upgraded pads" without a lot of research. OEM or HPS are great for the street. Getting track pads is stupid and dangerous. (real track pads). Stainless lines will give you better feel but you have to be really, really careful that the lines don't rub on the inside of a wheel or you'll lose it. They should be replaced yearly. For the street, I'd stick with OEM.

perrin turbo intake You said you're getting a Cobb SR. Stock is better than either choice.

and some cosmetics upgrades for eng bay (perrin alt shroud. ect.)

grimmspeed A/O seperator i already installed.

and i wanted to put in a new pump. main question is......Question should be "why do you think you need a new fuel pump. I don't think you need one. Money saved.

1. if i put in a DW300 pump will it run fine through stock injectors or should i upgrade?
2. at this point i will be running out of money set aside and have to delve into other funds. if not would the DW1000 drop in injectors work fine?
i have read mixed reviews.You don't need them with anything you've talked about here
3.or should i put in injector dynamics 1000cc top feed with rails. wich i will have to dish out another 250 just for steel line conversion for my car? and if so is this even necessary for my build?

any imput would be very much appriciated. ill upload pics later when i can get them on the pc.

I think I've saved you a butt ton of money on stuff that won't help you. You can believe me, especially when it comes to the brake stuff. Us New England guys did our own track testing of various brake stuff and I researched dba, which makes very nice, very expensive rotors that are not any better than $24 ones from Autozone performance wise

For the street, I'd stick with OEM. went with this kit because the whole kit when bundles was $550. with hps pads. not real track as im not planning on going to track. figured why not dish out a little extra for a better product then autozone.

perrin turbo intake You said you're getting a Cobb SR. Stock is better than either choice.i worded this wrong, its the perrin turbo inlet hose. the one that goes under the intake manifold. everywhere ive checked said almost everything is better then stock because the stock one is not smooth on the inside.

and some cosmetics upgrades for eng bay (perrin alt shroud. ect.)

grimmspeed A/O seperator i already installed.

and i wanted to put in a new pump. main question is......Question should be "why do you think you need a new fuel pump. I don't think you need one. Money saved. Wasnt going to but the people at equalibrium tuning suggested it.

A professional tune is absolutely worth the money over the OTS maps that Cobb provides. They drive better and make more power.

While engine and brake components are good. But I think suspension upgrades would be something you would appreciate also. Stage 2 with EWG. Then move into sway bars short throw shifter, and extreme performance summer tires Yokohama ad08r, and a set of winter tires nokian hakkapeliitta r2.

Some good suggestions. I have Whiteline 22mm f/r swaybars, KYB Agx struts with King springs, and Michelin PSS summer tires. Makes a world of difference. In winter I have Toyo Garit snow/ice tires which have proven themselves again and again.

x2 on the IDs. I had a set of DW injectors cost me my stock motor. I am ID for life now.

Also x2 on the IAG AOS. Very trouble free system that is very effective.
