Get all new gaskets for the DP and UP. Again, buy yourself a big bucket of restrain lol. The 02-07 5 sp gears hate a lot of horse/torque with abuse. The TGVs; check with your tuner. Some like to take them off with a 20G or bigger turbo. My tuner left them on because it helps keep the car a little more winter friendly and he knows how to work around them with a bigger turbo.

Update!

I got everything installed on Wednesday and had it tuned as well. Pushed 367 whp at 20 psi with an awesome power curve. I'll post my dyno charts soon.

On a side note...had my DW300 fuel pump crap out on me on my way home from my tuner last night. I just thank god that I was only doing 35 mph and not in boost when that happened. So I switched to a Walbro 250 today and it works like a charm!

Thanks again for all the help guys!

What kind of fuel? Sorry to hear about the fuel pump crapping out. I wonder why DW is having some issues lately. I saw that your profile said it was a dyno dynamics. That'd probably explain why its a little higher than me. My dyno is on a mustang dyno, so its a little lower reading than most.

Congrats on the build and doing a little homework. If I were you I would HIGHLY recommend that you start saving for that transmission yesterday.I ran almost 20K miles with my 20G enjoyed every minute of it on the stock clutch. But even under normal driving conditions it will start to wear out faster than under normal power levels. Like mentioned several times before Im the guy that upgraded the tranny and clutch/flywheel while deployed. When I got home I saw my stock gearset. It was on the way out the door for sure. Now with the gears and clutch I have a 4400 launch is a huge kick in the pants. Just remember that when the gears are upgraded your axles and possibly your drive shaft are the next weak link.

Kirt, sorry for taking so long to get back to you. I've been on family vacation for awhile and didn't have internet access.

I'm running E85 which is my tuners cup of tea. He really knows his stuff when it comes to tuning with it.

Ya my guess would be E85 and like you said "My dyno is on a mustang dyno, so its a little lower reading than most." We did a pull at 21 psi and it pushed 385 whp. He said he could have gotten 400 with a FMIC.

Also, sorry I haven't posted my charts yet. I need to run by the shop and upload them on my flash drive as well as some videos my tuner took while doing some pulls. Anyways I should have them up by the end of the week if not sooner. I have the hard copies just not the electronic ones unfortunately and my tuner is not the quickest when it comes to email.

Thanks Josh, I appreciate it! Lol, ya I have quite the laundry list of parts I'm saving for right now (i.e. STI brake kit w/ rims to fit the brembo's, new shortblock, STI full transmission swap).

I talked with a bunch of very reputable subi tuners as well as mine and they said as long as I don't do any launches, make sure that I'm completely in gear before getting on the throttle, and not jamming gears, etc, it should last me awhile. Its good to hear you were able to get 20K before having to do tranny work. Makes me feel a little more at ease.

Ya, I can't wait till I can fully enjoy my turbo! Hopefully sooner than later!!

Ah, makes sense that you are running E85 and got those numbers then. Nice numbers...I wish I could run some E85. Oh well...

Not a problem, glad I could help and share my knowledge. What are your long term plans/goals for the car? I ask because of the parts you listed. Not knocking them at all. Just wondering about the brakes for one. The 06/07 brakes are pretty capable, just get some SS lines, better fluid, and at least pads and they are a world of difference from stock. But the Brembos are pretty dang nice also. The shortblock I can agree with, as Im trying to save for that also. And the STI 6spd, its nice also, but the gearing is a world of difference from the 5spd also. I have a friend that just swapped a 6spd into his bugeye, he loves that he doesnt have to worry about his tranny anymore, but really disappointed in the ratios. Thats probably partially due to him being so used to a 5spd. Just bringing up some points to think about thats all.

Sounds like you got great advice on how to handle the power with the stock tranny. Its about the same advice I got before I got the work done no mine. You should be alrite following that advice and sticking to a stock clutch until you upgrade.

Congrats on the car and enjoy.

Hey Josh sorry for taking so long to get back to you. Anyways my long term goal for my car is to eventually be running 500+ whp.

So I already have upgraded pads (Hawk hps and SS lines) but I still experience to much brake fade for my comfort. So I'm thinking about just upgrading the front brakes to brembo's and then buying a big rotor kit for the rears. Ya, thats a pretty tough one for me because I love the 5 speed ratios but the 6 spd is so durable....i haven't completely made my mind up about that though. Definitely going to stick with the stock clutch every though its starting to slip...which is given. Thanks man and sorry again for being MIA.

My guess is because you are running a higher octane that it helps keep your hp flater up high. Mine starts to dip again around 5.5k rpms.

Does it really? When do you hit boost though? It doesn't show on my chart but my rev-limiter is set at 7100rpm and its quite surprising how it pulls all the way to 71k. But yes I would say that higher octane does have a contributing factor.

My car will put down more power than this when it comes back from having the head work, cams, and the engine put back together again. But, this is what it put down in 3-14-2011



You are also at a higher elevation, higher octane of fuel, and from the looks of it; using a different dyno also. My chart is from a mustang dyno.

Kirt I hate to tell you this, but your turbo should have been pulling harder than that all the way to redline and not dropping off at 5500. Granted it's slight, but something else was not right there. Not saying that the people who tuned your car are bad, just something mechanical wasn't right.
