Default Unflanged "sti style" turbochargers on an 08+ WRX

Is anyone here running any turbo with and unflanged outlet, like a vf/16/18/20G and a fmic on a 08+ wrx?
I just purchased an FMS fmic and I was wondering if it was possible to use the piping that was meant for an sti on the hot side of the ic without any fitment issues...and if not is there anything else that I need to get to run this style of turbo?
The install of all the parts will be sometime next year around the summer time. I'll be running an SBR 20g with all supporting mods (DW 850s, DW65c, Hallman MBC, one step colder NGK plugs) along with a bigger fmic.
***Clocking the turbo compressor won't be an issue either to get it to fit properly because I won't be using the iwg actuator on the turbo, I'll be running a GS uppipe/tial44 ewg***

Bump for a word of advice from the more experienced setter-uppers?

Sounds pretty simple then! I'm hoping I have all the right parts together so when it comes time to install everything I wouldn't have any setbacks. Was that pipe included with your fmic kit or did you have to make it yourself/buy it seperately?

I can confirm that it can be done pretty easily as long as you have a FMIC. For the PERRIN FMIC kits, you'll just have to get the LGT first boost tube to replace the 08+ WRX first boost tube and you're good!

The LGT first boost tube should be identical to the 08+ WRX. They share the same turbo design.

You mean the STI first boost tube to replace the 08+ WRX first boost tube?

It's actually the PERRIN LGT first boost tube, keep in mind this is if you are using the PERRIN FMIC only. They are different in the PERRIN kits.

How is your Perrin LGT tube different?

The physical 08+ WRX turbo shares the exact same hot side flange as the LGT. Your top mount for the LGT is the exact same top mount as the WRX? LGT turbo = WRX turbo.

The STi FMIC and the WRX FMIC have a different part number on your site, that is understandable that they use different piping. The LGT and the WRX use the same piping.

That's right that the TMIC is the same between the two cars.

The boost tubes between the LGT kit and the 08+ WRX kit are actually totally different though. When the 08 WRX came out, we started from scratch for the boost tubes, so it would be the best fit for the WRX. The LGT boost tube just has a little less of an angle to make it fit a little better.

How is it different? Every other FMIC manufacturer will fit both.

The LGT boost tube will not fit an STI. They are entirely different designs.

The angle is just a little different between the two. The 08+ WRX wasn't made specifically for a STI turbo, and it turns out that the LGT #1 boost tube fits a little better than the standard 08+ WRX first boost tube when running the PERRIN FMIC and a STI style turbo.

Well my front mount kit has been changed around. So the guy that reworked the pipes was payed with the leftover pipes. So I bought this small section from a speed shop. It's just a vibrant 2.5" pipe with a 45 bend

Are you guys using a 90* silicone to go from turbo>boost tube?

That's what I was trying to get at I think. How is the attachment functioning.

We actually include a metal 90 degree fitting that bolts directly to the turbo. Here's a pic that will help.

Thats not ****ing possible. The LGT and 08+ WRX turbos have a god damned flange on the compressor exit not a normal slip fit like the Sti and pre-08 WRX. So how the F would either the LGT or 08+ WRX first boost tube connect? The STi tube should drop right on. STi turbo on 08+ wrx with FMIC = use hot side piping from STi, cold side piping from 08+ wrx.

This is what I've been trying to say. The STI turbo does not have a flange. Something is not right here.

Please post pictures of the actual compressor.

Sorry for the confusion guys. The PERRIN FMIC includes a 90 degree adapter that bolts to the turbo that basically makes the pipe end up coming out at around the same place as a STI turbo would.



That way, the boost tube doesn't have a 90 degree in it like some other FMIC kits might. Hope that makes sense.

That's the answer I was looking for... thanks Leafy
