GR STI Build - Goal 500WHP on 93 OCT- PTE 6262

Justin V · 03-21-2013, 11:40 PM

Not my build. This is a fun build that's happening in my garage with parts by mail. The owner and I are just combining our knowledge of engines into what we hope will make 500whp on 93 OCT. The original plan was to drop the car off at a reputable subaru shop and go with a forged block and stock location turbo.

I came into the picture and with just the right amount of pressure I was able to talk the owner into building it ourselves. With the money saved, goals went from 400whp to 500whp, and stock location will be replaced with an ETS rotated kit with a PTE 6262.

This thread's goal is full disclosure. Any parts listed and shops used will be included. We got tired of talking to "turbo guy" and him saying oh yeah stock heads will make 500 you just need lagzilla turbo, or "shop x" saying no you don't want 500whp buy this 450whp package, and most importantly we avoided forums, we don't know if the guy on the other end of the computer is typing things based on personal experience, hear say, or just because its what he thinks is best.

The original motor over boosted after a bad email map was uploaded to run an ewg. We pulled the motor one weekend and took the long block to my house where we planned to disassemble it and send off the shortblock if needed and the heads.

Parts list will be in Post #2

So with all that said here is the ground breaking post so to speak. New block has arrived and the parts are trickling in.

This is an outfront closed deck EJ257. 11+ heat infused crank, H-beam rods, 100mm CP pistons, and king bearings. I cannot say enough about outfront, the block is amazing, service from them is great, and most of our parts came from them.

The crank - heat infused rainbow power

Rods

Serkan · 03-21-2013, 11:56 PM

Is it king xpg bearings in the block ?

Justin V · 03-22-2013, 12:26 AM

not really sure, the spec sheet just had "king's" written in. I'm sure outfront would be happy to tell you what kind they use

Zackbo · 03-22-2013, 08:26 AM

You might want to bump that injector size up a little for 500whp.

juanmedina · 03-22-2013, 08:55 AM

The owner should try the 6266 instead.. it seems that no one uses the 6262 anymore. I want to try the 6466 myself

. As far as the injectors he will be ok... but I have some 1200cc injectors for sale.

Nice build

Nice build

The 66 turbine wheel seems to pull hard up top even at low boost

Justin V · 03-22-2013, 09:25 AM

6266 was originally ordered, but we didn't want the additional lag. I was even considering going with a 5862.

Injectors were ordered before the first engine popped so were gonna go with them for now. If we can sell off some of theold stock location stuff a fuel rail setup is on the list which would make switching them later one easier.

You have a 6266, how much power are you making? A what boost? Fuel? Graphs?

RemlapaN · 03-22-2013, 09:53 AM

I don't see this hitting your goal.

To get to 500whp on a realistic dyno, you'll probably need any two of the following combinations in addition to what you've already done:

- Something other than the SPT catback exhaust
- Methanol Injection or E85
- Cams

Gonna be limited to 21-22 psi on pump fuel, and without cams you're gonna die on the top end. I'd say you're in the 450 range in current form.

Careful going with a lightweight pulley AND flywheel on a big turbo, large injector car.

insaneimpreza · 03-22-2013, 09:55 AM

Should be a easy 500whp car with that setup. I built a LGT Wagon for a buddy with my own custom rotated setup using a 5857 Billet BB Turbo and broke 450 on the automatic, so should be no prob on your setup there!

RemlapaN · 03-22-2013, 10:01 AM

Here's another car, running a 6262, tuned by one of the top tuners in the country:

http://forums.nasioc.com/forums/show....php?t=1963604

It was tuned on straight pump fuel, but they had cams and just BARELY hit 500.

They didn't hit peak whp until 6800rpm. The OP isn't going to have much if anything past 6200.

... Run more boost? The new 6262 have CEA wheels which will help. He will hit 500whp with that turbo on 93oct for sure

Justin V · 03-22-2013, 10:22 AM

Yeah I'm not worried about the number so much.

We picked the parts we wanted and think will work well together.

The number is the tuner's job, all these parts and a tune by me probably wouldn't even start. I'll make another thread after break in when we have it tuned.

All I know is dyno's vary, so that number doesn't matter much to me as long as there is a lot of area under the curve.

I'm really hoping the dual AVCS heads will make this thing shine.

Currently between Doug at Topspeed tuning it or Robbie Latta from Epic.
I really like the tune Robbie did for my car, and he is running a 6262 on his personal car so we'll all see in a month or so.

findurpath · 03-23-2013, 11:40 AM

Wow, that block looks awesome!

Subscribed for updates.

Junior2JZ · 03-23-2013, 07:35 PM

I would opt for the 66CEA wheel... The 62 causes lots of back pressure on the 2.5lt, and without doing the heads you will add to that.

Good luck making a real deal 500whp on 93.
We are currently building overboostin's 06 STi to reset his record for the 05 STi. This time with a 6266

Juan, running more boost isn't the answer when you are dealing with 93oct and backpressure. CEA or not

Justin V · 03-23-2013, 08:28 PM

Heads will be ported and large valves, don't know how much back pressure that will decrease.

We had the 6266 ordered but everything we saw and read showed full boost late in the rpms and were hoping for a more usable power band.

Do large runner heads help at all with back pressure?

Heedlessone · 03-23-2013, 09:08 PM

Wow, you don't see a closed deck 257 build too often.

Can't wait to see how this turns out!

Like I said, we set the pumpgas et/mph record with a 6262 a few years back. We are back at it and using a 6266, if I thought the 6262 was the right choice I would have used it again. I'm only going by my first hand data with both turbos.

Just an example, you can put a .5X ar hot-side on a 35r and spool faster then a .82... Doesn't mean its working the way it should.

I would stick to std size valves and a good bowl/port/valve job.

Justin V · 03-23-2013, 11:07 PM

I just couldn't find enough data to support using that large of a turbo. I haven't seen many subaru's running them and the ones that do are very peaky cars.

I was told to expect full boost around 6000 rpm out of a 6266, and while the owner would like to see 500 whp, we want it to be usable power ie reaching target boost at a lower rpm.

I really only have a few subaru's to compare it to, I'm running 311 whp mustang dyno numbers, a buddy here is at 393 with a dom1.5 on whatever dyno topspeed uses.

The dom really shines as a stock location turbo, and have heard great things about rotated 30R's but they seem to only put out slightly better numbers than a dom1.5 on pump and really shine on e85 when higher boost can be run. I really wish there was a middle ground between the 30R and 35R and thought the 6262 would accomplish that.

I compare the 30R and 35R because so many turbo's use those chra's (FP, Blouch, ATP)

Thanks for your input too, I really appreciate a reputable tuner's opinion.

I'd like to see a water injection system in use. The owner is opposed to e85 as it not readily available in Tampa, where the car will ultimately reside. I know with larger turbo's the boost needs to be up there to see them shine.

toph · 03-25-2013, 09:05 AM

Cool build man. My GR is getting a similar build (although I am only looking for 500whp on 110oct). Still trying to figure out what to do with the heads though, thinking I might send them to Element. I'll be going with the Dom3.5, not much data on it, we'll see what we can get out of it.

Why and how large of a turbo are you talking about?

jbulls93 · 03-26-2013, 06:56 AM

Seems like a capable setup! I notice that you didn't list the exact H-beams you are using, which rods are you going with?

FuJi K · 03-26-2013, 08:49 AM

This is what a 6266 spools like on e85 and supporting mods on stock cams.
