Default Turbo Questions.

Hello, I am new to the subie game. I just bought a 2002 bugeye. The block is out of a 2005 sti, but it has stock heads, etc. Im trying to figure out what turbo would be best for me. But I still want the car to be reliable, but quick. the mods I have currently are a cold air intake, full 3 inch cob exhaust, bigger tmic, cobb tuner, upgraded 2005 wrx tranny, stage 2 exedy clutch, sti pink injectors, perrin hoses and turbo inlet, go fast bits bov, kartboy short throw shifter, and that's about it. Like I said, I am just trying to find a slightly bigger turbo that I can make alittle more power with. Thanks!!!

a Holset HX35 would be slighly larger, you should probably get one of those.

I believe I have a stock Wrx turbo. Some of my subby friends say buy a vf39, how does that compare to the holset?

Also, do I have all the supporting mods for that turbo? If not, what all do I need?

Don't listen to him he is an idiot. That is a huge turbo! Go with a vf or big 16g.

Google is your friend. I believe Mr. Nugget is messing with you.

"Designed primarily for 6 cylinder engines of 5.0 to 6.5 liter capacity, the Holset HX35 turbocharger has high flow aerodynamics capable of providing up to 0.46 kg/s at 3.0:1 pressure ratio."

That turbo is too big. As for what turbo you should get, it depends on your budget and goals. Since you are looking for a bump in power, but want to maintain reliability, a VF39 or VF43 would be a decent choice. You already have the supporting mods. Since you have a 2.5 liter engine, you could go 18G for more power. But you'll need bigger injectors to realize the potential. And it will put more strain on your drivetrain, so there's that.

Weird, you have an 05 STi engine but the wrx turbo. Have you tried to see if you don't already have a VF?

Honestly, like I said I am just getting into the subbies, how can I tell what I have on it now. But I think that the only my block came from a sti, I think everything else is from a wrx. Does that sound right?

A vf39 or a small 16g would be a great upgrade then. You could use the sti injectors and an sti intercooler if you don't already have them. You will see a huge power gain with a tune of course. Td04 is a stock wrx turbo BTW.

Will the vf39 bolt right on? I already have the pink sti injectors, I believe they are 650cc. Do you think that's large enough or should I go bigger?

It will bolt right on. Your injectors are 565cc and are fine. You MUST get a tune if you go this route.

Waiting for Unabomber to come in and say this car is a ticking time bomb.

You really bought a car you have no idea what's done to it?

Why do you think it's an STI block?

I bought the car because it was cheap in my opinion. The guy was having some personal problems and needed some money. But he said it has a sti block, honestly I'm just going by what the previous owner has told me.

If I were you, I'd get a Garrett GT6041 as that's a really great turbo. It might be a little slow to spool, so I'd follow it up with a 200 shot of NOS to spool it.

1. Read the sticky threads....we have one titled Turbo FAQ and you need to read it about 32 times as you have no idea if you are afoot or horseback on this issue.
2. Where the hell in Maryland do you live? I can refer you to your closest Subaru-centric shop so they can screw your head on straight.

You can kindly bugger off is what you can do. Spamming your question in other people's threads is a violation of our forum rules AND that is covered in a sticky thread at the top of this and four other forums.

Check the stamp on the block to see if it's the sti block? Ej205 is 2.0l wrx ej257 is sti correct? Coulda just swapped sti block onto the rest of the wrx motor and kept td04. If it's says td04, you shouldn't be confused. That's what it is.
