Default Ultimate Upgrade path for the EJ257.

This is just my opinion from observing this board since the STi came out. Based on the dyno, the timeslips and posts from the community here, I came up with what I think is the ultimate upgrades list. Feel free to agree, disagree, or just add comments.

- Exhaust any 3 inch exhaust will do.
- Downpipe- a good 3inch bell mouth cause they seem to fit the easiest.
- Cobb AccessPort with ProTune (cause you could sell it if need be and it will pass OBDII)
- PE Injectors that have been cleaned and checked
- Walbro fuel pump
- Fujitsubo equal lenghts...why? Cause they use the stock uppipe (next part on the list) and the equal lengths seems to aid in the cooling of the motor. Of course they should be wrapped or coated, whatever you like.
- Ultimate Racing Externally Gated up-pipe. Since, you got the Fujitsubos, you can bolt this on without problems.
- Tial Wastegate...probably a 44mm, but something
- Perrin sized FMIC. (I'd even go ssautochrome to save some cash) I think the DR750s are just too big.
- FP Red Turbo. From reading Proven Power over and over, the GT rotated turbos make great power, but I think they work best on an inline motor where they are closer to their energy source. It seems like with the boxer motor they loose spool too quickly between shifts and that's why these rotated kits are in the high 12s-low13's or require nitrous to spool them to make the good times. I also do like the SZ turbos, but the FPs seem to be getting down the track quicker.
-Perrin inlet and intake...cause you'll need the big MAF and the bigger inlet hose for the Red...though I think Samco makes better hoses.
-Crawford block (you pick the one you want). I heard they can't get the 2.2 liter blocks anymore, so I don't know what that means in terms of product, but that 2.8 liter sounds awesome.

I tried to go in order of what you would buy stuff. But I think this is a path you can take without wasting money or trying a bunch of different stuff out. This is just my idea, so feel free to comment.
