new question....

1) what kinda compatability issues will i run into if i use a turbo kit on my 1.8 that was specifically designed for the 2.5 ( i.e. AVO )

2) what boost level should i run with the stock compression ratio? ( since its 10:1, i believe, idont think anything higher than 7 psi will break anything..

3) i have 90,000 miles... anything i should do before installation of a turbo kit?

 

1) Nothing major provided you get the one for your EM style, i.e MAF vs. MAP. I would recommend getting an RS hood and springing for a kit with a topmount.

2) The lowest boost you can run on the wastegate of the turbo you are getting.

3) Make sure every component of your fuel and ignition systems is in tip-top shape, and start saving for the inevitable meltdown. Might take 60-80,000 miles, but it's definitely going to break sometime with a turbo kit.

 

will the 2.0L WRX exhaust manifold bolt up directly to our 2.5L blocks?

 

the bolt pattern is the same, but I'm not sure if the spacing works out. I never got around to building my uber-RS-T motor.

 

gc8 in two door is in japan homey its the first breed ver3,buntas ride,as for turbo been there done that and waste money,do the swap i wish i did that,usdm wrx or ver8,faster and can boost higher,and with a two door its fast i road in one,it feels like an evolution.

 

2 door is still a GM, not a GC, regardless of where it's sold. Homey.

2 questions: Can u run the stock AVO setup on 6psi and drive responsibly and keep your engine in good nic?

And if you install the setup from AVO yourself does it need to be Dynoe'd/Tuned if wanting 6psi?

Thanx

 

At 6 psi you should be okay with just the RRFPR and SAFC.

 

Sorry to be a nub but what are RRFPR and SAFC?

 

Rising rate fuel pressure regulator, and SAFC is a fuel controller. Most kits come with these or a full ECU replacement.

 

try www.rallitek.com they seem to be creating tons of performance parts for the impreza 2.5i including turbo kits and air intakes.

 

BAN SUVS,

Man you've been owning this thread for about three years, eh?

Somebody had to do it, but why they let the n00b handle it is beyond me.
