Here's my situation:

I have a 2001 with 75k on it. Mostly stock. I'm looking to upgrade to a turbo setup.

These are the following items I already have:
305 Injectors
HSk 1.8 manifold (needs ERG Bung)
drill/tap
Garrett 2554 (SR20)



My question is:
Is it possible to run this (with other parts, lines, DP, BOV, FMIC), under lower psi (5-7) on the stock ECU?

I have an adaptronic e420c and wideband LC-1 but really don't want to run this if I don't have to.

I just have so many other "ad ons" going into the car right now and don't know if I'll have enough time/money to get it all together and still have time to enjoy it.

To do list:
Install new trans (broken reverse gear)
New clutch/PP/light flywheel
install new springs and AGX strut
finsh building and install LSD


I know I'll step up the turbo unit in a year or two, but I already have these parts. Any advice?

 

Disconnect the wastegate yet still look cool in front of your friends :P

Otherwise if you want boost install the 420.

You should be fine with the stock injectors for 5 psi of boost but you'll start running out of fuel at 6... you still need the standalone to control ---- though.

 

Well if I'm going to have to install the 420 anyway, I'm going to put more than 5 psi down.

Trip88: You have the 2554 right? Where do you start to spool and where is it full boost?
