wow, a gt30 huh. I hope you have deep pockets. To properly run this turbo you will need alot of internal work as well as everything else. Why not go for a 20g, or one of the common vf series turbo's, like the vf52 or vf39 etc. However at the very least you will need a bigger fuel pump, injectors, proper engine management and a tune. Look around for better options. A gt3076 is a big jump and will require thousands in upgrades to be ran.

 

Yeah I was looking at that because my buddy has a 07 wrx with a gt30 on it, he just has head studs, fuel pump, and 850cc injectors on a tune.

 

Must be a very very conservative tune with low psi in order for it to run safely. If not, your friends wrx may be a ticking time bomb. This turbo is usually used by people that have BUILT their engines to handle that kind of power. You know that this particular turbo is good up to around 500whp right? Unless subaru is installing a built block in your car, stay away.

 

Yeah he's only running 8lbs of boost on his

 

Do you know what the trim specs are on a 20g??

 

Here's a link. Also this turbo should be a direct bolt on to your 05. It is a very popular turbo on our cars and will make good power also. A much wiser decision over the garrett turbo IMO.

Blouch TD06H-20G-XT-R

 

So you recommend blouch over Garrett or Greddy? And TD06 over td05?

 

Blouch makes a very good turbo. So, yes, i would put them right up there with garrett. The TD06 is a popular upgrade for our cars. The only mods you should really need to run it is bigger fuel pump, injectors, a better intercooler, and a tune. And again it is a direct bolt on replacement.

 

Thought about going front mount, good or bad idea? I'm super new in the tuner game, this is my first tuner build

 

I am by no means taking anything away from garrett turbo's though. They make great power and great products. The "much wiser" comment was just referring that the blouch 20g will be a much friendlier turbo to upgrade too over the gt30.

 

If you're going with a 20g you'll need appropriate supporting mods. That's also going to add a lot of stress on your stock 5 speed.

 

Agreed, And this is the point im trying to get across to him. You cant just buy a big turbo and slap it on our cars. But a 20g will be much easier to handle than what he was originally interested in. If it was my build i would probably do a 16g.

 

A FMIC would be fine if ran with the 20g. But it is not needed. Look up process west intercoolers. They make a very nice top mount for our cars that would be perfect for your build. Plus it would be cheaper. And since this is your first build of a car like this. Do lots of research. Once you think your brain is full of subaru tuning knowledge, read everything again. These cars can be very tempermental and require a pro-tune for pretty much every upgrade after a stage 2 setup.

 

My problem is I'm going to have to trailer my car everywhere after every mod because there are no all wheel drive tuning places within 100 miles of me... and in reply to the stress on the tranny, I have a brand new tranny in my car with about 3000 miles on it with a stage 2 clutch

 

Brand new but is it the 5 speed or the sti 6 speed?

 

It's a 5 speed with hardened syncros. I don't want a 6 speed car

 

Hardened synchros? What about the gears?

 

If you get a cobb ap or even if you go the computer and tatrix route any reputable tuner will send you a limp map so you can safely drive it to them to have it properly tuned.

 

130 miles is a long way to drive on a stock tune pushing way to much fuel and boost through a car, especially in California

 

Gears are just new factory subaru gears

 

The gears are the main issue really. I mean the upgraded clutch will help. But wrx's are famous for glass-like gearboxs. The newer one's arent as bad as the older, but still arent the best. Anything above 350wtrq can cause issues with your tranny. However, the way you drive also plays a part it in. If you are out there banging gears like you are shooting the next fast and the furious movie and launching your car at every red light like a 16 year old then obviously the tranny will go out much much sooner.

 

Torque kills gears. So does stronger clutches. You always want the clutch to be the weak point.

 

Haha, good catch. I meant to say torque. (fixed) And you are right about the clutch wanting to be the weak point. Clutches are much cheaper than gearsets! And OP, intakes pretty much require a tune. However, and lytlec correct me if im wrong here, but the older wrx's were able to run intakes without a tune. If i am correct on that then the intake should be fine. Although at this time with your car being stock is basically just a noise maker.

 

This is my first all wheel drive car so I don't even know how to launch it, I've tried once and it smelt like burning clutch for 2 days so that's not going to happen again lol. I'm more scared of blowing the heads off it with too much boost than I am of blowing the trans.

Just read all this. It's a great start.

 

I already have an AEM cold air intake (true cold air, down in the fog light) could that give me issues?

 

Possibly. Especially if it isn't tuned for.

 

Like cause to spin bearings?

 

My car right now is sitting in the Subie shop with a blown motor. Haha

 

Did it have an aftermarket down pipe or anything else?
