Build Thread: xluben's 2011 WRX 5 Door Build Thread

Dropped in the Blouch 20G-XT-R last week. I did partial air pump deletes (got rid of everything in the way of the compressor housing, but I didn't pull the intake manifold off to get the last few pieces out) and I ended up using the AVCS oil line kit from FP. It's pretty slick and looks to be very well put together.

Nuke and I went out to tune it and first did a pull on wastegate pressure only. The wastegate spring on this turbo is 19psi, and the car made around 390WHP! Big jump from the ~350WHP that I was at with the VF52. We turned it up to 24psi and made 426WHP/438WTQ

For comparison, here is a layover of the curves on top of a recent VF52 log that I had. Should be all the same parts besides the turbo (ie. same exhaust, both have FMIC, etc). This shows the difference in spool and powerband between the two turbo's.

The turbo does spool about 500rpm's slower than the VF52, but you can see that it's really never making less power, so it is still very driveable on the street. I am really enjoying it so far! The power is very linear and it just keeps pulling on the top end, where the VF52 fell off. It is very addicting!

Thanks to Nuke for tuning me and helping me out all along the way!
