Is that better (edited)? I honestly think it is a good starting point for learning about how turbos work, turbocharged cars, etc.

I can remove my post it it bothers you that I am the one mentioning it.

You need more than just the turbo.

You need learning more honestly. Search, search, search and then search some more.

You need at a minimum:
catless uppipe
STi pink injectors
engine management
Boost and EGT gauges
a brain to not destroy your gears

You should also have:
dowpipe (catless or high flow), preferably a turbo back
fuel pump
IC hoses or different IC
custom tune
wideband O2 with readout
oil temp or pressure gauge

That's about it.

It is a good idea to take it easy after installing a new turbo, so you can see if the tune is good, and make sure everything is kosher. However, no break in is neccessary after installing a new turbo (aside from priming the CHRA).

I'd like to see one of those pictures since I have a VF39 right in front of me and am not seeing reference to a P18 exhaust side. From what I understand, divide by 25.4 to get what Garrett calls their A/R. Unless I'm looking in the wrong place, the only letters/ numbers on the exhaust side are:
R5
E2
17
3GW

17/25.4=.66 A/R which works out the same as using a telescoping micrometer and a tape measure to caluclate A/R.

Care to elaborate?

Anyone? From everything you guys have said, the exhaust housing is a P18. Mine says P17.

Sidefeed stock STI injectors are reported in this thread to be 480cc. I had all 4 of my stock injectors tested by both WitchHunter and RC Engineering.

WitchHunter results show 490-500cc.
http://www.bescaredracing.com/sti/fu...r/DSC05985.JPG

RC Engineering results show 517-524cc.
http://www.bescaredracing.com/sti/fu...ng/results.jpg

Basically, we are talking about a 25cc difference just by utilizing different companies. Also, keep in mind that if you get 1 injector flow tested then that means nothing since you could have tested either the lower flowing injector of the bunch or the higher flowing injector of the bunch. You need to have several tested. 10cc difference between my injectors.

Test the low flowing injector at WitchHunter and you get 490cc.
Test the high flowing injector at RC Engineering and you get 524cc.

It is now really easy for me to see, explain, and understand why some people said 480cc and why some people said 540cc. Lower flowing injectors vs. higher flowing injectors. One company vs. another company.

Default newbie turbo question

so i have an 03 wrx with the following:
STI top mount intercooler
Cobb AP (stage 1 flashed)
565cc injectors (not installed)
Upgraded fuel pump (not installed)
Full Cobb exhaust
Invidia Downpipe

Got a pretty good offer on a TDO 20 g turbo and was wondering what other supporting mods I would need to run to get maximum safe potential
thanks
