Getting the Engine Ready to Install

We decided that to day was a good day to get the engine off the old tire and on to the engine stand.  It was looking a little sad on the tire.



We were getting ready to install the Kinugawa twin scroll exhaust manifold, and we discovered two disappointing things: one of the runners on the right side was hitting both the oil pan and oil cooler, and the runners were actually about 3-5mm smaller in diameter than the stock manifold.  Why there would be fitment issues is a mystery to me since ostensibly this header is made precisely for JDM STI stock twin scroll engines like my version 8 ej207 motor.  We took it off and put the stock manifold back on.  We put the Kinugawa manifold in the corner to think about its short comings.


I snapped a pick of the OEM oil filter that was on the car when it was in Japan for posterity's sake.  Subaru PN 15208AA100.  After some quick searching on the Internet, these filters appear to be JDM only and are supposedly superior to the OEM blue filters.

I installed a cheap filter from O'Rilies that is intended for a USDM EJ205.  It seems to be fine.


Here is a close up of the Steam STX 71 twin scroll that we installed on the motor.


And then the STX 71 vs the stock IHI VF-37.


Here is the SteamSpeed silicone turbo inlet tube that will replace the smaller stock inlet.  FYI, the JDM STI stock inlet is larger that the USDM version.  I'll try to dig them up off of my shelf to show the comparison.


Wondered what the SteamSpeed AVCS oil feed lines look like?  Here it is installed on the Steam STX 71 turbo.


Here is a picture of the oversize intake ports of the version 8 ej207 heads to make USDM ej257 owners feel jealous.  :)

Domino Fender Rolling

Sorry for the gap in posts.  Too much work going on to make progress on my own car projects.  Next week should be better.

No doubt about it.  The GD STI suspension is a lot wider that the GC8's.  The wheels were sticking out at least 1/2" not to mention you need to run at least 17"x8" wheels to clear the Brembros which seem enormous compared to the stock 2001 RS wheels.  It looked like we were going to have a rub fest especially in the rear.  Time to break out the fender roller.  Anyone need Eastwood products?  We have a wholesale account with them now. :)  

Here is a starting picture.  Sorry, the angle doesn't how far out the wheels were sticking.


Here is the left side in progress.  


Here is the right side mostly done.  With a little camber adjustment, I think Domino will be rub free.  :)




JDM STI Versoin 8 Twinscroll

This is what the stock version 8 STI IHI VF-37 turbo look like vs the Steam STX 71 twin scroll turbo.

Hint: the STX 71 is a little bit bigger, but will make an extra 150 whp.



Stock twin scroll down pipe vs the 3" Kinugawa down pipe.  Pity it is no longer available.



Kinugawa twin scroll header...still available and nicely made.  Sorry, the stock manifold is still on the engine for the comparison.  It is actually nice to run by its self for the looks of it.
