will a sti turbo fit on an ej22t i think will please correct if i am wrong its an td05 right

The STi turbo is a vf39 I think. It has a different angle on the compressor outlet(IIRC) and would require a small amount of fabrication. The TD05 was a turbo that was available on the early wrx's(overseas) and I believe also available on the overseas legacy turbos. The 16g TD05 will fit though

do u know what else i'll need besides a bigger fuel pump to make this work these are the other things i know i need fcd intercooler mbc boost gauge anything else maybe bigger injector but i'm confused about that

LaureltheQueen · Post by **LaureltheQueen** » Wed Oct 12, 2005 10:05 pm

if you leave your boost settings alone, you should have no problem with your current fuel pump

you'll need bigger injectors if you turn up the boost. Alot of people have used nissan injectors, if you do a search, I'm sure you'll find some information.

You'll want to get a downpipe probably, the stock one is pretty restrictive

ok heres the deal on the vf39 seeing as im the only one here who has used one before. (windchaser bought it form me but i dont know if he ever installed it)

air inlet. you need to use a 90 degree adapter piece that you need to fabricate. you can do it 2 ways one of which is to make a restrictive inlet attached by silicone. it is restrictive for lack of space. the second way to do it is to remove the compressor cover and weld the 90 degree transfer to it. this is unrestrictive but it takes more guts to do it imo. third way to do the inlet is to literaly lift the turbo up and twist it. this is obviously called the twist kit. you will need to redo the down pipe and make an uppipe adapter. for this you will need 2 extra uppipe flanges avaible online. this third option will allow you to keep the stright inlet which also helps spool. for this though you need to use a front mount intercooler. with the amout of custom fabrication needed to do it this way its a waste not to have a front mount.

stock boost control will work and it will work well, the problem with this is that the vac nipples on the turbo and wg actuator are smaller than the nipples on the boost control solenoid. smaller by a fair amount too. if you get lines that barely fit over the stock boost control solenoid they will be very loose over the nipples on the turbo. this results in a stock boost control of 14psi solid. this equates to about 12 psi at sea level.

next issue is the oil suply line. the stock suply line is not long enough this is remidied by cutting the stock line and putting a flex hose between the two ends. where you cut it and the length of line is crusial or it wont fit and youll have to do it again. i recomend you take this piece to be done at a hose speciaties shop. tell them to use steel braided teflon coated flex line rated at 14psi. you will also have to reaneal the washer gaskets or get new ones.

next issue on line is the coolant suply line. for this it is recomended that you use the stock water line off your stock turbo. the lower line on the vf39 hits the uppipe and doesnt allow it to sit down. but the stock line doesnt fit on the turbo either unless you hit it with a hammer. there is a strew that holds the compressor cover on that is on the verry bottom where the lower water line goes next to. you will need to get the line bolt on as much as possible and then bang it into place or it will do what the vf39 line does. you can just hit the 39 line with a hammer too if you wish. you will need to use the stock upper line or flip the upper line around to get it to work. this requires cutting the tab that keeps both lines together.

fuel pump is not nessairaily nessary. i still havent installed mine yet. fcd is more nesary but not entirely if you use a mbc.

other than fabrication of turbo inlet and having to fabricate turbo to throtle piping and intercooler stuff you will need the folowing suplies

1 deep socket 14mm 6 point socket and extentions
1 fixed open end and closed end 14mm wrench
1 hammer
1-2 cans of pbblast or liquid wrench
1 wrx uppipe gasket
1 wrx downpipe gasket
6 17mm banjo bolt copper gasket washers (avaible at your local parts counter. ask for oil turbo coolant inlet washers)
2 10mm banjo bolt wahsers
1 10mm socket
1 12mm socket
1 oil return hose
misc vac lines

i think that about does it.

thanx for the info i think with my know how and the aid of the forum i can do this thanx but if anyone knows exactly what injectors i might need in the future let me know

Uh, 14 psi?

sorry. 14 thousand psi. i meant to put a "k" there

Ah, ok.

I've got an extra set of 93-94 NA fuel rails that you'll need if/when you are looking to upgrade your injectors. As for the injectors themselves, best bet is probably a search, there's been a lot of discussion on it.

you should not need any fuel mods unless you go over 15-16 psi. Here are some pics of my vf34 installation.

Great set of pics.

I'm trying to decide between the 16 or the 34, and to have it done this winter. Your comments would be helpful.

Also, what up pipe are you using?

Post by **Legacy777** » Sun Oct 23, 2005 8:27 pm

Mike,

Is the bracket in this pic critical?
http://www.thawa.net/gallery/IHI-VF-34- ... cture1_033

I don't think I installed that on mine. I don't plan to run the chimney or heat shields....so I didn't really look into installing any of that crap.

magicmike · Post by **magicmike** » Mon Oct 24, 2005 12:07 am

yes that bracket supports the up-pipe and the weight of the turbo.

oh and its a GT-spec header with catless up-pipe

Post by **Legacy777** » Mon Oct 24, 2005 3:07 am

Hmmm....wonder if I should put that on.

lol have you been running without one? that cant be good...

vrg3 · Post by **vrg3** » Mon Oct 24, 2005 3:08 pm

For the short term you're probably fine without it, but I guess FHI figured the extra strain on the uppipe and downpipe could conceivably eventually cause problems. Of course, you're using different materials for those pipes (or at least the downpipe) than stock, so thermal expansion behaves differently now...

Some WRX folk remove that bracket (or just unbolt it from the head) because they think it causes their uppipe leak.

From what I've seen on other cars, it seems that most OEM turbo setups have brackets to support the turbocharger while most aftermarket setups don't bother with it.

Post by **Legacy777** » Mon Oct 24, 2005 5:49 pm

Mike,

I haven't been running period

But when I get the engine running I was just curious if I should put that on.

magicmike · Post by **magicmike** » Mon Oct 24, 2005 11:54 pm

ahh ic, well good luck with that then

Post by **Legacy777** » Tue Oct 25, 2005 2:15 am

Not sure I'm going to bother putting it on. I'd have to take the turbo off and all that jazz.

93forestpearl · Post by **93forestpearl** » Tue Oct 25, 2005 6:07 am

Would you say that the downpipe basically hangs on the turbo? I wouln't know because I don't have one in a car to look at.

I like the idea of the bracket, but I dunno how I'd use it. Maybe I'll be able the bend it with a torch.

vrg3 · Post by **vrg3** » Tue Oct 25, 2005 1:25 pm

The downpipe is bolted to the turbo and to the transmission. Without the turbo support bracket, it's not clear to me whether it hangs onto the turbo or vice versa.

magicmike · Post by **magicmike** » Tue Oct 25, 2005 2:46 pm

Chances are that if your upgrading the turbo you would be upgrading the up pipe and the downpipe like I did. In which case you lose all the support brackets from the factory equiptment. The way I look at it the turbo bracket lines up the top of the up pipe and supports the turbo in a steady place in space. the downpipe is then supported at the top by the turbo and down at the bottom by the tranny.

I have an aftermarket uppipe and downpipe but am still using the factory turbo support bracket.
