esemes, I plan on buying a fresh set of pe850's...and also sending my stock ones out to perrin to be modified, If I remember correctly the modified stock injectors are 740cc...then I will have a set in case(God forbid) I blow and injector or something....I've read alot and have been planning this out...so by spring I'll be done...at what I feel will be the "Ultimate Sleeper". I havent had the misfortune of losing a race yet(street)...but its time to put it on the track and shut some people up(cough,evo,cough) .Spring cant come soon enough!!! Peace

my cousin went thru the quantico training when he joined the fbi (many years ago)....

quite an experience, to say the least (and the least was all he really could say, if memory serves)

enjoy the hi-speed/shotgun activities!

If you get an external wastegate vent it to your downpipe. Believe me, they're realllly loud and venting it to your downpipe quiets it down a bit...

They are all good choices. Personally, I like the PE850's, with an aps sr50 and hyperflow topmount. I have seen this setup put down 385whp on pump gas, and the lag was minimal. I say the sr50, because I have not seen the sr55 put down any more power, and yet it seems to have more lag. The green without a doubt seems to be putting down the best numbers so far, but I have heard about parts breaking and blowing engines . I like a top mount, because I have seen people put down nearly 450whp on race gas with a top mount and no detonation. Personally I like how it keeps the factory fit, and minimizes lag....and yes it does make a noticable difference. If you are going for a drag setup, I say to either get a green or garett. For whatever reason the power bands of the aps turbos don't seem to do well in the quarter-mile. I am still undecided myself, but am in the same boat. Good luck deciding :wink: .

Hey esemes. It's level 3 training. Shouldn't be classified. Shooting through winshields, pitting(advanced), breakout from block in, shooting thru ambushes. Stuff like that. I don't know, maybe I won't like it......RIGHT!!! I'll tell ya about it if I can. Good luck with picking your turbo. I think we are looking for the same thing out of our cars. Keep me posted and I will tell you how mine is coming along. Later, Sam

ese...

While my knowledge of turbos is still limited, coming from the NA camp, All I have to say is I am glad we live so close, so I get a ride in that beast. I still have not rode in your car after the reflash!

One thing I will point out is that it behooves you to buy everything from the shop you will be having do the install and tuning. When I say "you" I mean "you" and not every person that reads this thread. I am only saying this because we have spoken extensively and I understand what your level of satisfaction is and what costs you would not mind incurring in the short run for peace of mind insurance if something should go wrong some time in the long run, however possible or unlikely those "things" or problems might be.

If you buy a turbo made by W, sold by X, installed by Y, and dyno tuned by Z, you have created a long chain of people who can blame each other should their be any warranty work issues or problems to trouble shoot down the road. Compare that scenario to buying Turbo made by W from Z who also installs and tunes it for you. Guess what, if something goes wrong, there is really no other place to point a finger. If it was the manufacturer, then they can supply you with what you need in the event of a problem and handle the warrantly claim.

Most people will say any warranty claim is doubtful, but however unlikely it may be, we know anything is possible. I am not saying pay the extra money to have the piece of mind that this transaction setup affords is worth it or should be paid, but what I am suggesting is that it should be considered even if eventually crossed off your list.

GREAT dATA!!

how, praytell, can i calculate the potential 'lag' of these units??

im up to that section in my book with turbo sizing, but am still very green (no pun intended) as to what combinations of sizes equate to what output levels...

i guess i need to get the compressor maps, an then grasp some firm understanding of them as well (in reference to the sti as well)

to add to the above thoughts, i do have an upgraded TMIC already; i chose the ES-x version of the SPEARCO grande model (bigger than the wrx's spearco model too)... it is gigantic, an took alot of work to get it to fit correctly, and i am keeping it. it runs very cool, and only gets soaked once the car has sat for sometime... my reading has also drawn the conclusion that the I/C at 2½" wide is the most width needed (anything above that is well, excessive, so i drew the conclusion that the aditional 2" of my spearco can/may act as a heatsink, and holds the heat from the turbo underneath - maybe not affecting the intake temps as much as it is thought to...)

just a poorly spelled ramble, but it is a theory nonetheless.....

hmmmm
on the street near me on sti (04 specifically) im seeing alot of fp green, 850 cc inj. larger top mount tuned at 91 oct. these cars are monsters and are showing very good reliability. the guys im seeing are not forum writers they are alot of former import supra clubers(sog). ive been for a ride in 2 and .. well...impressive !
i laid down 309 on race gas with cobb stage 2 and greddy headers and a walbro. i only have one place left to go....BIGGER turbo BIGGER injectors and tuning. i talked to trey in vegas at sema and they are working on a stage 3 with a turbo and injectors they are leaning to a pe1818 or something "like that"
interesting read... keep em comming !

good point(s)

as you know, Mastro (subaru) willbe doing my install and tiuning. they are HEAVY into aps.... if memory serves, i saw a sr40(?) in their showcase, as they stock alot of the big red fast stuff....

your opinion is VERY valuable, and after many hours of talking on the phone, i take your word weighted very heavy.

i guess i need to keep the ideas coming, but also get with Bill @ mastro and see if he stocks/gets/has any experience with the other prouct we are discussing....

looks like this so far::

1) injectors (perrin 825)
2) turbo (aps SR series)
3) oem rails
4) can that be all i need to get to the next level safely???

no beefed up motor mounts (thought the 2005 has hardened sti mounts already)

sheesh... maybe only two components needed??

[salisburyv]

definately get the STI motor mounts and tranny mounts...my motor used to flex causing my uppipe gasket to fail...with the new mounts no flex AT ALL!!! pretty cheap upgrade too. my .02

Thanks Scott!

Best advice: Ride in as many upgraded STis as possible, so you can say I want THAT (pointing to the car with the mods you wish to have) and KNOW what you are getting before you buy it rather buy some combination of parts based on what you read posted in the forums by people that do not have or know a ton about the particular parts they are suggesting (no offense to those who are experts in the field of turbos).OR even worse, or even worse, posted by people who have a completely different subjective judgment about turbo lag (this is a primary concern with regard to turbo selection).

I know I do not know enough to feel truly competent to suggest anything other than how to go about selecting the turbo setup that is best for your particular needs. I would continue to do your searching and find what you feel would meet your needs. Then, approach Bill at Mastro if that is who you WANT to do your tuning, and then ask him if he has any experience with those companies and if we would be willing to setup accounts with those companies so that he may sell you the products. Tell him what prices you have found for them, and tell him how much you are willing to pay to buy them from him (since he does have to spend the time to setup all the accounts and hassles that go along with that). Make a condition of the sale be that he will give you the same product support as he would if he were to sell you any of the other products he is currently stocking or any other conditions you would like to add since you are going to spend a significant sum of money with his company.

If I were lucky enough to be able to provide you with all the parts and services for this setup, you would have gotten to be King for a day!
