Default Build Time for the 2007 Limited STI..w/Updates

I hate to say it (dont know if this i good or bad news) but the 2007 Sti Limited I have invested so much in to is starting to get tired,,,,the stock block that is. I have always been prepared for this but didnt know when it would happen. I have been pushing 400whp on an ATP 3076 stock location turbo for the past 25,000 miles and it is starting to produce white smoke, white smoke out of oil cap, check engine light that cannot be read, and blow by oil leaks through charge pipes and bov. The car now has close to 84,000 on the stock block.

Its time to start the build. I brought it to my friends shop, Fast in West Chester. Looking forward to seeing what they can do. My as well go all out on this build and get a beast out of it since the exterior and interior is flawless on the vehicle. Also it has brand new fuel pump, gates water pump kit, tensioners, timing belt, etc. Looking in to large rotated turbo or Borg Warner Twin Scroll. I will be parting out all my stock location parts which some parts have less than 1k miles on them...if your looking for a deal! I guess I canot get too crazy with this since it is my daily driver. Would assume the 500whp mark is safe and obtainable.

Current Engine Mods:
ATP GT3076r Stock Location Turbo 3"inlet
44mm Tial External Wastegate with Dumptube
TGV Deletes
Perrin Front Mount Intercooler
Tial 50mm BOV
Perrin 3" Turbo Inlet
Invidia Catless Downpipe
Perrin Single Tube Catback Exhaust
DW 850CC Injectors
Walbro Fuel Pump
Gates Water Pump
KsTech 70mm Intake
GT Spec Unequal Length Headers
ACT Stage 2 Clutch
ACT Lightened Flywheel
Kartboy Short Shifter
Mishimoto Aluminum Radiator

Current Numbers with this setup....396/393 at 18psi


I will update you on this process as Im excited and hope to get input and opinions on what is being done. Will be going in tomorrow with the grocery list which I will then share here.

This is her in her glory day

Update: Compression test done...Cylinder two read 70. The breakdown is beginning. I really need some opinions.

The cost of the build alone is $1400. An additional $1200 to sleeve it. Is it worth it to sleeve?

Also, is this the time to go "all out". Rotated? Twin Scroll? I guess it depends really on my wallet. The shop is recommending the twin scroll from Borg Warner or I could take it easy and simply go rotated. Looking for opinions. Do not know if this sould be transferred to the build forums.

If you're building the block up then why not play hardball? I would put as much power as I could into it. Did you find out what is damaged in the stock block? Your car looks really nice.. what suspension do you have and other exterior mods? I am planning on putting 400WHP to my stock block. I hope it doesn't end up like yours.

It took 25-30k miles to cause this. It is expected on these engines. Frankly I'm surprised it lasted this long. I am dropped on twin ss-p coils....rolled and pulled fenders. Lot of mods! Ha. I will find out what was technically damaged when the block arrives to the machine shop early next week. I will post pics and let u know! I think I will go all out power/turbo wise....why not tight!

Just a question to those that built...is it worth sleeving it for extra cost?

Yes it is worth it, the block is already apart and it dose give you the option for bigger power in the future. Even if you don't it is nice to know that have a pretty indestructible block (so to speak)


And yes my block is Dan Benson sleeved. Well worth it.

any updates?

you mentioned the 8374. is that what you settled on? EWG or IWG?

you mentioned this is your dd, what are you using while it's down? have you placed your order for the EFR yet?

i have an EWG 7670 ordered to replace my 7064 and know it's going to be a while and i ordered a while ago and was just making sure you knew how much time you could be down because they are just starting to get their t3 frame turbos in, ya know?

keep the photos and updates coming! i'm excited to see more TS EFR results posted and shared!

Hey monki yes I saw our thread that u wanted to change to this setup as well. I just ordered my pistons rods etc. The machine shop should have them tomorrow. I have been driving my second vehicle...3004 Toyota highlander....its brutal. The wait is killing me. Hope to have car back right before Thanksgiving. Efr order is placed. I'll get more pics and updates...just a lot of waiting at this point.

i'm going to a 7670, actually. the 8374 would be a bit much for my purposes and i prefer responsiveness over whp numbers for my application, haha. you are going to make gobs of power, though!

that's awesome you have your order placed. did you go EWG or IWG?

you want to have your car back up and running by thanksgiving with your newly ordered TS EFR?!! i doubt i'll have my 7670 this year and your 8374 won't be in even after those and you know how many folks are ahead of you. i dont know sir, i think you should plan accordingly for a february/march receipt of your 8374.

regardless, it's gonna be bad when you're done!

I have been told the 8374 is November arrival. Very excited for it. Looking forward to FAST of West Chester taking care of everything. Communication has been great! I get pics up soon

ok, well good luck. i guess if you're getting yours in november and the 7064 and 7670s are coming a month or so before, i should be getting an email right around SEMA week, haha!

sorry if my 14-month wait that was supposed to be 2 months for the 7064 has left me a bit skeptical and cynical of the BorgWarner delivery estimates.

did you order EWG or IWG? did you finalize on using the full-race TS kit, as well? or will FAST be fabbing something up for you?

It utilizes two internal waste gates. Yes I'm using full ts kit. And it has been confirmed that cylinder 2 ring land went. Said if I kept driving it would of needed entire long block

so you ordered an IWG 8374, ok. and i think you might be confusing the two. the IWG has one 42mm valve head/36mm port not two. the TS EWG model will require an uppipe that utilizes two EWGs as it's obviously divided.

and since you're IWG, i have the high-pressure canister you'll need that i'll sell to you cheaper than you'll get from full-race. i have no need for it now as the person that bought my 7064 wanted the medium canister and i am on order for the EWG 7670. it's already threaded further up the shaft to work with subaru fitment which saves some hassle. shoot me a PM if interested!

Things are coming together. Turbo will arrive this week and will be coated. Should have at the shop next week. Hoping everything will be installed and ready for the tuner by Xmas. Great communication with Dave and Roy from FAST. Making this long wait worth it in the end!

The charge pipes come painted black (as everything else in my engine bay is ie; manifold, tgvs, rad hoses) do I want to pay the extra $175 to get the intercooler core painted black?
