As has been mentioned, the TD04 and VF-10/11 are very similar in size.
A '96ish WRX? Well, the engine was redesigned in '97, and went to the TD04 at that point. the '94-96 WRX's had a TD05 on them. I have seen conflicting reports, but some say that the 220hp '94-96 wagons ran a TD04...

The only problem will be the inlet. Your stock turbo has the 90 degree inlet from intake plumbing that runs around the intake manifold. Unless if came off of a pre '96 car, the TD04 will not have the elbow...

or just buy a silicon hose at a 90 degree bend. Then use a section of pipe to connect boot B with the silicone hose. I cant remember the size of the boot B or the size of the inlet on the wrx but they should be similar, a reducer might be needed.

I might be able to come up with another TD05 from a Version 2 STI if you're interested. We just got done putting a TD05 from a 1996 WRX on his 1990 Turbo Legacy, Along with a WRX Intercooler. I'll post pictures tomorrow if anyone wants to see them. Or you could go the route of the Silicone Hose like Subiekid said.

yea, please post them. its good to just get ideas from other peoples work. my wrx ic setup involves the APS cast pipe, with a few aditional sections of silicone pipe. Its not on due to lack of a hood scoop, and being at college I cant work on my car.

Deadbolt sells turbos with the 90 inlet conversion already done for you, as another option. Keep in mind a TD05 will require bigger injectors, which means custom fuel rails since no injector upgrades exist for the Ej22T...

Default pics

Overall Shot of Engine Bay (What's not shown in this pic is the WRX Coolant Tank...Had to get rid of the stock plastic pile of crap)


Pic of the stock Bypass valve


Shot of 90 degree Radiator hose for turbo outlet


Stock WRX Y-Pipe that has been cut so I could put the metal pipe in to lengthen the inlet tube.


Stock USDM WRX Turbo on Left Stock Turbo Legacy VF11 on Right


Stock VF11 From 1991 Turbo Legacy


Shot of 90 degree Radiator hose for turbo outlet


A problem we're having is that the stock bypass valve is open at idle and is recirculating / venting air all of the time. We didn't know that at the time we took the recirc part off of the intercooler. It seems an aftermarket BOV would fix that. It could also explain why the car is running extremely rich.

on the bov part, what I am using is a bov adaptor. I got mine for 20 bucks on this site. Its so that you can mount like a turboxs bov to the wrx ic. Instead of running an aftermarket bov, I took a section of hose, connected it to the bov adaptor, then hooked that to the OEM legacy bov, then i connected another hose to the other end of the bov and ran it to the boot B. (i know its not a real bov, its just easy to type bov then bypass valve)

I dont have it hooked up and I am not at home so I cant take pics, sorry.

Matt, what turbos can you get from deadbolt with the 90 degree angle? can I get a vf22 with a 90 degree angle or just the older 16g?

You have no idea how much of a pain in the ass it is to get that intercooler on and off. There is not enough room to take it off as you would normally. Basically we leave it attached to the throttle body, and just take the two coolant lines, the four bolts, and the throttle cables off to get the intercooler off. There isn't enough room between the firewall to just take it off how you normally would on a wrx (unbolt the two bolts, undo two hose clamps and take 3 pcv lines off, and it basically slides right off) Oh Well... We also had to take about a quarter of an inch off of the Intercooler (The flange that the hose connecting the intercooler to the throttle body clamps to), and another quarter inch off the throttle body (The flange that the hose connecting the intercooler to the throttle body clamps to) so that the intercooler would have enough room to clear the firewall...and We've only got about 1/4" between the firewall and the edge of the intercooler. THe AC line was tucked down a little bit, the O2, Cam, Crank, and Knock Sensor connectors were all lengthened and moved out of the way so we'd be able to access them incase one of those sensors went bad. THe WRX Coolant Tank is zip tied on for the time being...But it's a hell of alot better than the stock plastic tank that likes to break if you even look at it wrong.

he needs one with a 90 ADDED to it, Deadbolt sells ones that HAD a 90 on them, changed to a straight inlet.
The TDO5 will not require bigger injectors if he does not have the custome 16-18-20G internals. The WRX's that came with TDO5's didnt have bigger injectors.

Funny, That's not what Deadbolt said in that thread...

And while the 94-96 WRX's can run fine on their stock 425-440cc injectors, going with any significant amount of boost on the 390cc USDM purple tops will quickly run out of the fuel delivery capabilities of the injectors. You can run a TD05-16g on those injectors, but you cannot turn up the boost on them...

yeah deadbolt has the 90s on the turbos availble.

as for injectors bac5.2 over on lco is running 16 psi on a 16g with a sabb900 and stock injectors and a whal.255 lph pump. he may have a pressure regulator too.

legacyej22t on the other hand has a deadbolt monster and blew the crap out of his motor.

Pre ver 3 WRXs have 90 degree elbow TD-05s. Ver 3 WRX/STis came with IHI turbos VF22 in the WRX and VF23 in the STi both without elbows. The turbo will depend of the engine EJ20G= TD05 and EJ20k= IHI

The RSliberty guys say they are 370cc on the vf-10 powered EJ20g and mine are grey top
IIRC the 425's are brown top.
I'll have to look into this some more as this has been raised a few places recently and I am beginning to wonder how much power I can get out of my EJ20G without changing the injectors. Or maybe I should get it running before I worry about that.
