i dont want to rebuld my engine right now so i am looking for a good turbo that wont harm my engine
just for street use mostlly

Well on revtronix's website it says you could use the stock turbo for stage 2, but your best bet is to just get a cheap TD04 from a wrx, 440cc injectors, and get the IC in at the same time with the td04.

For a WRX td04 you need a silicone y-pipe that you will cut up and a 90 degree silicone coupler to get the intake to work.

Search the site for detailed instructions of the above parts.

Get:

JECS MAF
06-07 TMIC
eBay hose kit as shown in various threads, be prepared to "custom fit"
JDM 440cc injectors
Revtronix Stage 2 for the above setup and TD-04

It appears that various turbos within the TD-04 to VF-39 range work OK with the tuning, for instance I am running a VF-8.

Install all of this at once, and if your motor is old I highly recommend that you get new intake manifold gaskets, throttle body gasket, all engine bay vacuum lines, fuel hoses, and injector o-rings.

thx since im getting new injetor news one ill be fine ill check my hose and vaccum too
still looking for a td04 and y pipe i got the tmic today 07 wrf top mount, and i also have the jecs maf.

what is the size of the exaust oem one?
bcuz they said on rev i should go for 2.5 inch or more!

any good place where i can get some gasket ? i think i may have some intake leak. but thx for all the info im geting close to get all the part

anyone have apicture of the 90 degree silicone coupler ? so i can figure out where i can get it?

thx for the help guys

As I recall stock exhaust on a SS is 2"

I got the exhaust of a 07 STI and it was 2 1/2 inch. Its real quiet and perked up the motor a bit. Running stock boost until I do my Intercooler/Turbo swap so cant really say how it performs beyond 8psi.

I'm sure that temporarily the stock exhaust would be OK. It will just hurt spool times and overall performance.

I'm running a 3" catless DP and the 2.5" STi cat-back. It's quiet, and I am looking for something a bit more performance oriented, but stealthy.

Does a wrx have a 2.5" exhaust as well? Also the stock SS has a 2 1/4" exhaust. A wrx has 3 converters and a resonator. I am sure using a stock exhaust on the chip will be fine considering we only have 2 converters.

The WRX is the same size as the stock exhaust, IIRC.

how do you bolt the dp 3 inch with a 2.25 exaust? need adapter or something?

I had a new flat flange welded on the STi midpipe to match the flat 3" flange.

FYI any Impreza exhaust needs to be lengthened a few inches and the rear hangars repositioned to work on the Legacy.
