That downpipe looks fanatastic.

Lachute Performance did a spectacular job on my own catted/rerouted/rotated dp,
but damn this one looks amazing as well. Ceramic coated?

Yes, Cerakote on the pipes. It was supposed to be titanium color to match my headers

Making progress with the shop. They just moved in to a ~20,000sqft facility that will be both a storage place for exotics/race cars, as well as brand new state of the art engine room facility, dyno room, and the rest of the shop strictly for performance builds.

My car is one of the first being finished at the place



Heres the partial assembly on the stand. Shop is really worried about turbo placement right now with how the IAG rails are lining up. Tigwerks seems confident with his setup, since its all built from a jig and has others running the same setup. Crossing my fingers there is either a bit more rotation or something left on the turbo to clear the fuel connectors.

After reading this I went to take a look at mine; seems pretty damn close as well...within a cm of the turbo silicon coupling piece.

To get some more clearance could the shop not just rotate the turbo a bit?
It is a v-band connection right?

It's a weekend car mostly for the streets.

What would you recommend, considering you have experience with the updated platform?
i have a bit of experience with them.. especially in a scenario like this, i can
imagine how the stock suspension would handle this power increase..
yes, the chassis is amazing but they are still set up to understeer and be
as compliant as the oem set up can be from the factory.
even if the car is mostly just out in the streets, slightly tuning the suspension
will make it a bit safer, and sharper/more lively when or if you do
get it out in to some curves or even the track.
from both the stock 15 wrx and sti i've sampled briefly in the canyons recently,
i'd say no matter what; even the "go to" steps would give you a better experience..
springs, rear sway, a proper alignment (even if you're only around -1.8 in the
front), and some spacers to widen your stance touch.. it won't be too
low, and won't be too much stiffer than oem depending on what you purchase.

at least then you won't lose the ability to dip and squat under braking and initiation or on throttle exit by being too stiff, but you'll have a better turn in, and more ability to steer the back end under throttle.

just my $0.02.. some may disagree.


plus it'll look better, right? haha.
keep it up, man. good luck.

Thanks for this! Are you also running the IAG rails? The next step for the shop is to rotate the turbo slightly (yes its vband) to see if it helps. Just not sure how much bend the downpipe has in it. Sending your pics to the shop

I am currently running RCE Yellows and 20mm Perrin spacers, with an alignment. It definitely eliminated any understeer and feels perfect to me. I may add stiffer sways and some lower control arms once I start getting acquainted with the new changes.

Happy to help
Yes I am running the iag rails.
Based on my own fitment I'm sure they can make it work. They'll either have to turn the turbo a little more, or worst case scenario trim a bit off the downpipe to get some more room to maneuver.

oh, nice.. haha, well then I must have missed that.

out of curiosity; what were you able
to max the negative camber up front
since you're not using camber plates?
I know my 06 was capable of -1.8 stock
but a friend was recently curious about
his 15..

Quick update from shop***8212;with some rotation it looks like it clears. Turbo isn't in exact position rotation wise, but it could work. Its at a pretty extreme angle, just need to test downpipe now.

Most excellent. Happy they could make it fit. Break in time must be soon... looking forward to seeing what is essentially my exact mods will make with more serious psi. I initially thought I'd go to 24psi with the aquamist 50/50 kit I just had installed, however I hit my goals at 21psi and more aggressive timing+leaner afr. Block longevity is a concern for me, car is a dd and I opted to keep things more conservative. You look like u gonna unleash the fury....

Skipping the turbo blanket?

Turbo blanket will be on for sure It's probably another 10 days before they are done, pending the fitment of the down pipe. They are super backed up with the move to the new facility, and i'll be out of the country for 2 weeks so I'm not in a huge rush.

Things are getting close! The downpipe was hooked up, and it allowed for enough rotation at the turbo to BARELY clear the fuel lines. However, the downpipe is almost touching the trans now Not terribly impressed with the Tigwerks setup here.

Turbo had to be rotated upwards so as to not have to touch the PS lines. Surge tank is going in next, and we're almost done!

Default pet3r's 2015 STi Launch Edition // EFR7163, IAG Closed Deck

IAG AOS in. It doesn't look quite like the octopus I was expecting.

Was able to fire her up and drive home today! BIG kudos to Archie over at Crown Concepts in Tucson (formerly PSI). Their new facility is off the hook!

Everything went off without a hitch today. No leaks, no noises, all good. Engine runs super smooth thanks to Ron @ Phatbotti (as always).

First impressions of the new 7163 turbo: its so hard to keep it out of boost! Even with the lightest throttle amount, at any RPM, in any gear, puts it at positive pressure. I'm following IAG's break-in instructions to the T though. Oil changed at 50 miles, and put another 50 on tonight. Got to get to around 1000 miles before we can go WOT

I'm loving it. Fine choice in parts man; glad to see its going well so far.

Your psi ambitions have me eager to see what my own efr7163 setup could achieve at higher psi.

I forget if your gonna push e85 or meth...

Doing E85 with Cobb flex fuel! Hoping the recent laws in AZ don't force E85 to E50 in my area

Thanks! I'd rather not think about the cost, lol

IAG had their motor prices on their site. Somewhere around $4500 I think for a closer deck?

Installed is probably $2k-$3k depending on what other mods you might also be doing.

Car is slightly limping right now. P0017 is a cam/crank mismatch. I think I might have skipped timing. Hoping to figure it out tomorrow.

Car runs fine and makes power still, except the S# boost levels will increase from target of 27 back up to 32, and whp drops like a rock. The cams can't advance with the CEL so the boost increases and runs very inefficiently. If I run 91 gas it's solid on boost since it's much lower.
